Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
General Basis of Presentation	'
	General Basis of Presentation
	The interim consolidated financial statements included herein have been prepared by Duke Realty Corporation (the "General Partner") and Duke Realty Limited Partnership (the "Partnership"). In this Report, unless the context indicates otherwise, the terms "Company," "we," "us" and "our" refer to the General Partner and the Partnership, collectively, and those entities owned or controlled by the General Partner and/or the Partnership. The 2013 year-end consolidated balance sheet data included in this Quarterly Report on Form 10-Q (this "Report") was derived from the audited financial statements in the combined Annual Report on Form 10-K of the General Partner and the Partnership for the year ended December 31, 2013, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). The financial statements have been prepared in accordance with GAAP for interim financial information and in accordance with Rule 10-01 of Regulation S-X of the Securities Exchange Act of 1934, as amended. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenue and expenses during the reporting period. Our actual results could differ from those estimates and assumptions. These financial statements should be read in conjunction with Management's Discussion and Analysis of Financial Condition and Results of Operations included herein and the consolidated financial statements and notes thereto included in the combined Annual Report on Form 10-K of the General Partner and the Partnership for the year ended December 31, 2013.
	The General Partner was formed in 1985, and we believe that it qualifies as a real estate investment trust ("REIT") under the provisions of the Internal Revenue Code of 1986, as amended (the "Code"). The Partnership was formed on October 4, 1993, when the General Partner contributed all of its properties and related assets and liabilities, together with the net proceeds from an offering of additional shares of its common stock, to the Partnership. Simultaneously, the Partnership completed the acquisition of Duke Associates, a full-service commercial real estate firm operating in the Midwest whose operations began in 1972.
	The General Partner is the sole general partner of the Partnership, owning approximately 98.7% of the common partnership interests of the Partnership ("General Partner Units") at June 30, 2014. The remaining 1.3% of the common partnership interests ("Limited Partner Units" and, together with the General Partner Units, the "Common Units") are owned by limited partners. As the sole general partner of the Partnership, the General Partner has full, exclusive and complete responsibility and discretion in the day-to-day management and control of the Partnership. The General Partner and the Partnership are operated as one enterprise. The management of the General Partner consists of the same members as the management of the Partnership. As the sole general partner with control of the Partnership, the General Partner consolidates the Partnership for financial reporting purposes, and the General Partner does not have any significant assets other than its investment in the Partnership. Therefore, the assets and liabilities of the General Partner and the Partnership are substantially the same.
	Limited Partners have the right to redeem their Limited Partner Units, subject to certain restrictions. Pursuant to the Fifth Amended and Restated Agreement of Limited Partnership (the "Partnership Agreement"), the General Partner is obligated to redeem the Limited Partner Units in shares of its common stock, unless it determines in its reasonable discretion that the issuance of shares of its common stock could cause it to fail to qualify as a REIT. Each Limited Partner Unit shall be redeemed for one share of the General Partner's common stock, or, in the event that the issuance of shares could cause the General Partner to fail to qualify as a REIT, cash equal to the fair market value of one share of the General Partner's common stock at the time of redemption, in each case, subject to certain adjustments described in the Partnership Agreement. The Limited Partner Units are not required, per the terms of the Partnership Agreement, to be redeemed in registered shares of the General Partner. The General Partner also owns preferred partnership interests in the Partnership ("Preferred Units").
	We own and operate a portfolio primarily consisting of industrial, office and medical office properties and provide real estate services to third-party owners. Substantially all of our Rental Operations (see Note 10) are conducted through the Partnership. We conduct our Service Operations (see Note 10) through Duke Realty Services, LLC, Duke Realty Services Limited Partnership and Duke Construction Limited Partnership ("DCLP"), which are consolidated entities that are 100% owned by a combination of the General Partner and the Partnership. DCLP is owned through a taxable REIT subsidiary. The consolidated financial statements include our accounts and the accounts of our majority-owned or controlled subsidiaries.

New Accounting Pronouncement [Abstract]	'
New Accounting Pronouncements, Policy [Policy Text Block]	'
	New Accounting Pronouncements
	Discontinued Operations
	In April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("ASU 2014-08"). Under ASU 2014-08, only disposals representing a strategic shift in operations (for example, a disposal of a major geographic area or a major line of business) will be presented as discontinued operations, while significant continuing involvement with such dispositions will no longer preclude discontinued operations classification. As current GAAP generally requires companies that sell a single investment property to report the sale as a discontinued operation, the implementation of ASU 2014-08 will result in us reporting only sales that represent strategic shifts in operations as discontinued operations. ASU 2014-08 will also require additional disclosures for discontinued operations as well as for material property dispositions that do not meet the new criteria for discontinued operation classification.
	ASU 2014-08 is effective for fiscal years beginning on or after December 15, 2014, with early adoption permitted only for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. We adopted ASU 2014-08 early and have applied it with respect to such items since April 1, 2014.
	Revenue Recognition
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 is a comprehensive revenue recognition standard that will supersede nearly all existing GAAP revenue recognition guidance as well as impact the existing GAAP guidance governing the sale of nonfinancial assets. The standard’s core principle is that a company will recognize revenue when it satisfies performance obligations, by transferring promised goods or services to customers, in an amount that reflects the consideration to which the company expects to be entitled in exchange for fulfilling those performance obligations. In doing so, companies will need to exercise more judgment and make more estimates than under existing GAAP guidance.
	ASU 2014-09 will be effective for public entities for annual and interim reporting periods beginning after December 15, 2016 and early adoption is not permitted. ASU 2014-09 allows for either recognizing the cumulative effect of application (i) at the start of the earliest comparative period presented (with the option to use any or all of three practical expedients) or (ii) at the date of initial application, with no restatement of comparative periods presented.
	We have not yet selected a transition method nor have we determined the effect of ASU 2014-09 on our ongoing financial reporting.

Consolidation Policy for VIEs	'
	Variable Interest Entities
	In June 2014, one of our unconsolidated joint ventures, which we had previously determined to be a variable interest entity ("VIE"), sold its sole property and repaid all of its third-party debt. The sale of this property caused the joint venture to no longer meet the criteria to be considered a VIE. As such, at June 30, 2014, there was one remaining unconsolidated joint venture that met the criteria to be considered a VIE. This unconsolidated joint venture was formed with the sole purpose of developing, constructing, leasing, marketing and selling or operating properties. The business activities of this unconsolidated joint venture have been financed through a combination of equity contributions, partner/member loans, and third-party debt that we have guaranteed. All significant decisions for this unconsolidated joint venture, including those decisions that most significantly impact its economic performance, require unanimous approval of the joint venture's partners or members. In certain cases, these decisions also require lender approval. Unanimous approval requirements for this unconsolidated joint venture include entering into new leases, setting annual operating budgets, selling underlying properties, and incurring additional indebtedness. Because no single entity exercises control over the decisions that most significantly affect this joint venture's economic performance, we determined there to be no individual primary beneficiary and that the equity method of accounting is appropriate.
	The following table provides a summary of the carrying value in our consolidated balance sheet, as well as our maximum loss exposure under the guarantee for the one unconsolidated subsidiary that we have determined to be a VIE at June 30, 2014 (in millions):
		Carrying Value			Maximum Loss Exposure
	Investment in unconsolidated companies	$	6.2		$	6.2
	Guarantee obligations (1)	$	(5.0	)	$	(99.4	)
	-1	We are party to a guarantee of the third-party debt of the joint venture that we have determined is a VIE, and our maximum loss exposure is equal to the outstanding borrowings on the joint venture's debt. The carrying value of our recorded guarantee obligation is included in other liabilities in our Consolidated Balance Sheets.
	Our maximum loss exposure for guarantees of joint venture indebtedness, including guarantees of the debt of joint ventures that are not VIEs, totaled $212.9 million at June 30, 2014.

	Acquisitions and Dispositions
	2014 Acquisitions
	We acquired two industrial properties, a building in Atlanta, Georgia and a building in the Lehigh Valley region of Pennsylvania, during the six months ended June 30, 2014. The following table summarizes the fair value of amounts recognized for each major class of asset and liability (in thousands) for these acquisitions:
	Real estate assets	$	80,731
	Lease related intangible assets	9,857
	Total acquired assets	90,588
	Other liabilities	54
	Total assumed liabilities	54
	Fair value of acquired net assets	$	90,534
	The leases in the acquired properties had a remaining life at acquisition of approximately 9.2 years.
	We have included $1.6 million in rental revenues and $5,000 in earnings from continuing operations during 2014 for these properties since their respective dates of acquisition.
	Fair Value Measurements
	The fair value estimates used in allocating the aggregate purchase price of each acquisition among the individual components of real estate assets and liabilities were determined primarily through calculating the "as-if vacant" value of each building, using the income approach, and relied significantly upon internally determined assumptions. We have determined these estimates to have been primarily based upon Level 3 inputs, which are unobservable inputs based on our own assumptions. The range of most significant assumptions utilized in making the lease-up and future disposition estimates used in calculating the "as-if vacant" value of each building acquired during the six months ended June 30, 2014 were as follows:
		Low		High
	Discount rate	7.38	%	7.68	%
	Exit capitalization rate	5.98	%	6.38	%
	Lease-up period (months)	12		12
	Net rental rate per square foot – Industrial	$2.75		$4.46
	Acquisition-Related Activity
	The acquisition-related activity in our Consolidated Statements of Operations and Comprehensive Income for the six months ended June 30, 2014 and 2013 consisted of transaction costs related to completed acquisitions, which are expensed as incurred, as well as gains or losses related to acquisitions where we had a pre-existing non-controlling ownership interest. We expensed $761,000 and $2.7 million, respectively, for acquisition-related transaction costs incurred in the six months ended June 30, 2014 and 2013. During the six months ended June 30, 2013, we also recognized a gain of $962,000 on the pre-existing ownership interest that we held in an industrial property we acquired in that period.
	Dispositions
	We disposed of 21 consolidated income-producing real estate assets and 86 acres of undeveloped land during the six months ended June 30, 2014. We received net cash proceeds from property and land dispositions of $213.0 million and $259.2 million during the six months ended June 30, 2014 and 2013, respectively.
	Income tax expense from continuing operations of $3.0 million was the result of the sale of a property that was partially owned by our taxable REIT subsidiary but, due to continuing involvement in managing the property, was not classified as a discontinued operation. Income tax expense included in discontinued operations of $3.5 million was also the result of the sale of a property that was partially owned by our taxable REIT subsidiary where we have no continuing involvement.
	During the six months ended June 30, 2014, two office properties were sold by two of our unconsolidated joint ventures, for which our capital distributions totaled $40.3 million and our share of gains, which are included in equity in earnings, totaled $58.3 million. These two office properties included a 436,000 square foot office tower in Atlanta, Georgia.

Indebtedness	'
	Indebtedness
	All debt is held directly or indirectly by the Partnership. The General Partner does not have any indebtedness, but does guarantee some of the unsecured debt of the Partnership. The following table summarizes the book value and changes in the fair value of our debt for the six months ended June 30, 2014 (in thousands):
		Book Value		Book Value				Fair Value		Payments/Payoffs			Adjustments			Fair Value
		at 12/31/13		at 6/30/14				at 12/31/13					to Fair Value			at 6/30/14

	Secured Debt
	Because our fixed rate secured debt is not actively traded in any marketplace, we utilized a discounted cash flow methodology to determine its fair value. Accordingly, we calculated fair value by applying an estimate of the current market rate to discount the debt's remaining contractual cash flows. Our estimate of a current market rate, which is the most significant input in the discounted cash flow calculation, is intended to replicate debt of similar maturity and loan-to-value relationship. The estimated rates ranged from 2.20% to 4.10%, depending on the attributes of the specific loans. The current market rates we utilized were internally estimated; therefore, we have concluded that our determination of fair value for our fixed rate secured debt was primarily based upon Level 3 inputs.
	During the six months ended June 30, 2014, we repaid six secured loans, totaling $82.2 million. These loans had a weighted average stated interest rate of 5.59%.
	Unsecured Debt
	At June 30, 2014, with the exception of one variable rate term note, all of our unsecured debt bore interest at fixed rates and primarily consisted of unsecured notes that are publicly traded. We utilized broker estimates in estimating the fair value of our fixed rate unsecured debt. Our unsecured notes are thinly traded and, in certain cases, the broker estimates were not based upon comparable transactions. The broker estimates took into account any recent trades within the same series of our fixed rate unsecured debt, comparisons to recent trades of other series of our fixed rate unsecured debt, trades of fixed rate unsecured debt from companies with profiles similar to ours, as well as overall economic conditions. We reviewed these broker estimates for reasonableness and accuracy, considering whether the estimates were based upon market participant assumptions within the principal and most advantageous market and whether any other observable inputs would be more accurate indicators of fair value than the broker estimates. We concluded that the broker estimates were representative of fair value. We have determined that our estimation of the fair value of our fixed rate unsecured debt was primarily based upon Level 3 inputs. The estimated trading values of our fixed rate unsecured debt, depending on the maturity and coupon rates, ranged from 99.00% to 126.00% of face value.
	We utilize a discounted cash flow methodology in order to estimate the fair value of our $250.0 million variable rate term loan. The net present value of the difference between future contractual interest payments and future interest payments based on our estimate of a current market rate represents the difference between the book value and the fair value. Our estimate of a current market rate was based on estimated market spreads and the quoted yields on federal government treasury securities with similar maturity dates. Our estimate of the current market rate for our variable rate term loan was 1.31% and was based primarily upon Level 3 inputs.
	The indentures (and related supplemental indentures) governing our outstanding series of notes also require us to comply with financial ratios and other covenants regarding our operations. We were in compliance with all such covenants at June 30, 2014.
	Unsecured Line of Credit
	Our unsecured line of credit at June 30, 2014 is described as follows (in thousands):
	Description	Maximum		Maturity Date		Outstanding
		Capacity				Balance at
						June 30, 2014
	Unsecured Line of Credit - Partnership	$	850,000	Dec-15		$	60,000
	The Partnership's unsecured line of credit has an interest rate on borrowings of LIBOR plus 1.25% (equal to 1.40% for outstanding borrowings at June 30, 2014) and a maturity date of December 2015. Subject to certain conditions, the terms also include an option to increase the facility by up to an additional $400.0 million, for a total of up to $1.25 billion. This line of credit provides us with an option to obtain borrowings from financial institutions that participate in the line at rates that may be lower than the stated interest rate, subject to certain restrictions.
	This line of credit contains financial covenants that require us to meet certain financial ratios and defined levels of performance, including those related to fixed charge coverage, unsecured interest expense coverage and debt-to-asset value (with asset value being defined in the Partnership's unsecured line of credit agreement). At June 30, 2014, we were in compliance with all covenants under this line of credit.
	To the extent that there are outstanding borrowings, we utilize a discounted cash flow methodology in order to estimate the fair value of our unsecured line of credit. The net present value of the difference between future contractual interest payments and future interest payments based on our estimate of a current market rate represents the difference between the book value and the fair value. Our estimate of a current market rate is based upon the rate, considering current market conditions and our specific credit profile, at which we estimate we could obtain similar borrowings. The current market rate of 1.41% that we utilized was internally estimated; therefore, we have concluded that our determination of fair value for our unsecured line of credit was primarily based upon a Level 3 input.

	Shareholders' Equity of the General Partner and Partners' Capital of the Partnership
	General Partner
	In the first six months of 2014, pursuant to the share repurchase plan approved by our board of directors, the General Partner repurchased 750,243 preferred shares from among our three outstanding series. The preferred shares repurchased had a total redemption value of approximately $18.8 million and were repurchased for $17.7 million. In conjunction with the repurchases, approximately $618,000 of initial issuance costs, the ratable portion of such costs associated with the repurchased shares, were charged against income attributable to common shareholders. As the result of these repurchases, an adjustment of approximately $483,000 was included as an increase to net income attributable to common shareholders.
	During the six months ended June 30, 2014, the General Partner issued 11.0 million common shares pursuant to its at the market equity program, generating gross proceeds of approximately $193.1 million and, after deducting commissions and other costs, net proceeds of approximately $191.1 million. The proceeds from these offerings were used for general corporate purposes, which include the funding of development costs.
	In April 2014, the General Partner's shareholders approved an increase in the number of authorized shares of the General Partner's common stock from 400 million to 600 million.
	Partnership
	For each common share or preferred share that the General Partner issues, the Partnership issues a corresponding General Partner Unit or Preferred Unit, as applicable, to the General Partner in exchange for the contribution of the proceeds from the stock issuance. Similarly, when the General Partner redeems or repurchases common shares or preferred shares, the Partnership redeems the corresponding Common Units or Preferred Units held by the General Partner at the same price.

Net Income (Loss) Per Common Share	'
	Net Income (Loss) Per Common Share or Common Unit
	Basic net income (loss) per common share or Common Unit is computed by dividing net income (loss) attributable to common shareholders or common unitholders, less dividends or distributions on share-based awards expected to vest (referred to as "participating securities" and primarily composed of unvested restricted stock units), by the weighted average number of common shares or Common Units outstanding for the period.
	Diluted net income (loss) per common share is computed by dividing the sum of basic net income (loss) attributable to common shareholders and the noncontrolling interest in earnings allocable to Limited Partner Units (to the extent the Limited Partner Units are dilutive) by the sum of the weighted average number of common shares outstanding and, to the extent they are dilutive, Units outstanding and any potential dilutive securities for the period. Diluted net income (loss) per Common Unit is computed by dividing the basic net income (loss) attributable to common unitholders by the sum of the weighted average number of Common Units outstanding and any potential dilutive securities for the period. The following table reconciles the components of basic and diluted net income per common share or Common Unit for the three and six months ended June 30, 2014 and 2013, respectively (in thousands):

	Reportable Segments
	We have four reportable operating segments at June 30, 2014, the first three of which consist of the ownership and rental of (i) industrial, (ii) office and (iii) medical office real estate investments. The operations of our industrial, office and medical office properties, along with our retail properties, are collectively referred to as "Rental Operations." Our retail properties, as well as any other properties not included in our reportable segments, do not by themselves meet the quantitative thresholds for separate presentation as a reportable segment and are referred to as non-reportable Rental Operations. The fourth reportable segment consists of various real estate services such as property management, asset management, maintenance, leasing, development, general contracting and construction management to third-party property owners and joint ventures, and is collectively referred to as "Service Operations." Our reportable segments offer different products or services and are managed separately because each segment requires different operating strategies and management expertise.
	Revenues by Reportable Segment

	Supplemental Performance Measure
	Prior to 2014, we evaluated the profitability of our reportable segments using net earnings excluding depreciation and other items that were not allocated to our operating segments. As the result of a shift in the focus of our executive management team on the metrics used to evaluate the performance of, and to allocate resources among, our reportable segments, we elected to change our segment measurement of profitability beginning with the period ended March 31, 2014. We have also revised prior period information in order to provide period-over-period comparability.
	Property level net operating income, on a cash basis (“PNOI”) is the non-GAAP supplemental performance measure that we now use to evaluate the performance of, and to allocate resources among, the real estate investments in the reportable and operating segments that comprise our Rental Operations. PNOI for our Rental Operations segments is comprised of rental revenues from continuing operations less rental expenses and real estate taxes from continuing operations, along with certain other adjusting items (collectively referred to as "Rental Operations revenues and expenses excluded from PNOI," as shown in the table below). Additionally, we do not allocate interest expense, depreciation expense and certain other non-property specific revenues and expenses (collectively referred to as "Non-Segment Items," as shown in the table below) to our individual operating segments.
	We evaluate the performance of our Service Operations reportable segment using net income or loss, as allocated to that segment ("Earnings from Service Operations").
	The following table shows a reconciliation of our segment-level measures of profitability to consolidated income from continuing operations before income taxes for the three and six months ended June 30, 2014 and 2013, respectively (in thousands and excluding discontinued operations):

	The most comparable GAAP measure to PNOI is income from continuing operations before income taxes. PNOI excludes expenses that materially impact our overall results of operations and, therefore, should not be considered as a substitute for income from continuing operations before income taxes or any other measures derived in accordance with GAAP. Furthermore, PNOI may not be comparable to other similarly titled measures of other companies.

	Total properties sold or classified as held-for-sale	2		21	38		61
	As described in Note 2, we adopted ASU 2014-08 beginning April 1, 2014. Three properties were designated as held-for-sale at March 31, 2014, and met the criteria for discontinued operations that were applicable prior to the adoption of ASU 2014-08. Two of these properties were sold during the three months ended June 30, 2014, while one of these properties continues to be designated as held-for-sale at June 30, 2014. No new properties, whether having been disposed of or designated as held-for-sale, have met the criteria for classification as discontinued operations since the adoption of ASU 2014-08.
	For the properties that were classified in discontinued operations prior to the adoption of ASU 2014-08, we allocated interest expense to discontinued operations and have included such interest expense in computing income from discontinued operations. Interest expense allocable to discontinued operations includes interest on any secured debt for properties included in discontinued operations and an allocable share of our consolidated unsecured interest expense for unencumbered properties. The allocation of unsecured interest expense to discontinued operations was based upon the gross book value of the unencumbered real estate assets included in discontinued operations as it related to the total gross book value of our unencumbered real estate assets.
	The following table illustrates the operational results of the buildings reflected in discontinued operations for the three and six months ended June 30, 2014 and 2013, respectively (in thousands):

	The income tax expense included in discontinued operations during the three and six months ended June 30, 2014 was triggered by the sale of a property that was partially owned by our taxable REIT subsidiary.
	The income tax expense from continuing operations of $364,000 and $3.0 million for the three and six months ended June 30, 2014, as presented in the Consolidated Statements of Operations and Comprehensive Income, was related to the sale of another property that was partially owned by our taxable REIT subsidiary but, due to continuing involvement in managing the property, was not classified as a discontinued operation.
	Dividends or distributions on preferred shares or Preferred Units and adjustments for the redemption or repurchase of preferred shares or Preferred Units are allocated entirely to continuing operations for both the General Partner and the Partnership.

	At June 30, 2014, one in-service property, which was classified in discontinued operations prior to the adoption of ASU 2014-08, met the criteria for designation as held-for-sale. Additionally, one in-service property met the criteria for designation as held-for-sale subsequent to the adoption of ASU 2014-08, but does not meet the criteria to be classified within discontinued operations.
