Item 3. Source and Amount of Funds or Other Consideration.

The reporting persons may be deemed to have acquired beneficial ownership of 330,432 Units pursuant and subject to the terms of the Purchase Agreement (defined below), which provides, among other things, that the owner of such Units, HWG, LLC, a Delaware limited liability company ("HWG, LLC"), will vote such Units (i) in favor of the Merger Agreement (defined below) and the Merger (defined below), (ii) against any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Partnership under the Merger Agreement, and (iii) against any action or agreement that would be reasonably expected to impede, interfere with, delay, postpone or attempt to discourage the Merger; and further provides for the grant by HWG, LLC to HRPT of an irrevocable proxy to vote the Units held by HWG, LLC in accordance with the foregoing. These voting rights were granted to HRPT in consideration of entering into the Purchase and Merger Agreements.

The foregoing description of the voting provisions contained in the Purchase Agreement is qualified by reference to the Purchase Agreement attached as Exhibit 2.

SCHEDULE 13D

CUSIP NO. 40636T203

Page 7 of 11 Pages

Item 4. Purpose of Transaction.

On April 16, 2004, HRPT, one of its subsidiaries ("Merger Sub"), the Partnership and Hallwood Realty, LLC, a Delaware limited liability company and the general partner of the Partnership (the "General Partner") entered into an Agreement and Plan of Merger (the "Merger Agreement"), under which, among other things, (i) Merger Sub will merge with and into the Partnership (the "Merger"), with the Partnership surviving the Merger and becoming a wholly-owned subsidiary of HRPT, and (ii) holders of Units and options to purchase Units will receive the consideration described below.

In connection with the Merger Agreement, HRPT, one of its subsidiaries ("Successor GP"), the General Partner, HWG, LLC and certain other affiliates of the Partnership entered into a purchase agreement (the "Purchase Agreement"), under which, among other things, (i) HWG, LLC agreed to vote its Units, and granted HRPT a proxy to vote its Units, as set forth in Item 3, (ii) Successor GP will acquire the 330,432 Units held by HWG, LLC and the general partner interest in the Partnership, and (iii) the sellers under the Purchase Agreement will receive the consideration described below.

The aggregate consideration payable for the Units and the general partnership interest is approximately $250 million, subject to adjustment in certain circumstances. Consummation of the transactions are conditioned upon satisfaction or waiver of the conditions set forth in the Merger Agreement or the Purchase Agreement, including approval of the transaction by the holders of Units and obtaining certain consents.

The foregoing descriptions of certain terms of the Merger Agreement and the Purchase Agreement are qualified by reference to the Merger Agreement and the Purchase Agreement filed as Exhibits 1 and 2, respectively.

No changes to the business, management, policies or organizational documents of the Partnership are anticipated to occur prior to the Merger. If the transactions contemplated by the Merger Agreement (including the Merger) and the Purchase Agreement are consummated, it is expected that subsidiaries of HRPT would hold all of the general and limited partnership interests of the Partnership, and accordingly that the Partnership would cease to be a public company, that the Units would cease to be traded on the American Stock Exchange and that the Units would become eligible for termination of registration under Section 12(g)(4) of the Act. After the consummation of the Merger, HRPT may elect to make such changes in the business, management, policies and organizational documents of the Partnership as it deems fit.

Item 5. Interest in Securities of the Issuer.

Pursuant to the Purchase Agreement, HWG, LLC has granted HRPT a proxy to vote the 330,432 Units held by it (which represent 20.7% of the issued and outstanding Units) in favor of the Merger Agreement and the Merger. To that extent, HRPT may share the power to vote and therefore may be deemed to beneficially own such Units.

To the knowledge of HRPT, RMR or RMR Trust based solely on the information set forth in the Schedule 13D filed on July 24, 1993, as amended, by The Hallwood Group Incorporated, a Delaware corporation with its principal executive offices located at 3710 Rawlins, Suite 1500, Dallas, Texas 75219-4298 ("Hallwood"), and certain representations contained in the Merger Agreement and the Purchase Agreement, (i) Hallwood has sole dispositive and voting power over the 330,432 Units held by HWG, LLC, except to the extent voting power over such Units is shared with HRPT pursuant to the terms of the Purchase Agreement as described above, and (ii) no other person is known to have the right to receive or the power to direct the receipt of distributions from, or the proceeds from the sale of the Units held by HWG, LLC. Hallwood has reported additional information with respect to its beneficial ownership of the Units held by HWG, LLC in the above-referenced filing by it on Schedule 13D, as amended.

The trustees and executive officers of HRPT, RMR, as HRPT's investment manager, and RMR Trust, as the sole member and manager of RMR, may under applicable regulatory definitions, be deemed to beneficially own the 330,432 Units over which HRPT shares voting power; however, such persons disclaim beneficial ownership thereof. Further, (i) other than as set forth in the Purchase Agreement and the Merger Agreement, none of the reporting persons is entitled to any rights as a holder of Units, and (ii) the filing of this Schedule 13D shall not be construed as an admission that any reporting person is, for purposes of Section 13(d) or 13(g) of the Act, the beneficial owner of any Units.

Other than entering into the Purchase Agreement and the Merger Agreement, to the knowledge of the reporting persons no transactions in Units have been effected during the past sixty days by HRPT, RMR, RMR Trust or the trustees, directors and executive officers of HRPT, RMR and RMR Trust described above.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Except for the arrangements described in Items 3, 4 or 5 of this Schedule 13D, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the reporting persons or, to the knowledge of the reporting persons, any other person or entity referred to in Item 2, or between such persons and any person with respect to any securities of the

issuer, including but not limited to transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
