Source-derived summary

The Investment Building is a high-rise office building in Washington, D.C. The building rises 13 floors and 154 feet (47 m) in height. The interior renovation and redesign of the building was by architect César Pelli; Pelli also designed the Petronas Twin Towers in Kuala Lumpur. The renovation was completed in 2001. As of July 2008, the structure stands as the 32nd-tallest building in the city, tied in rank with 1310 G Street, 1430 K Street, 1875 K Street, the Westin Washington, D.C. City Center, the Executive Tower, 1701 Pennsylvania Avenue the Capital Hilton and The Westin Washington, D.C. City Center. The building is composed entirely of commercial office space.

The Investment Building is partially composed of elements from an older building of the same name that was designed in 1910 by Jules Henri de Sibour, and completed in 1924; the building was partially demolished, but its historic facade was preserved. The modern Investment Building rises two floors higher than its predecessor.

The building is principally occupied by Sidley Austin, the sixth largest law firm in the United States; and by the Washington office of UBS. Its ground floor houses The Catholic Information Center, a Catholic bookstore.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as office in D.C., United States. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 25, 2026. The linked authority identifier is Q7742422. Authority coordinates are 38.903, -77.035. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001, 2008, 1310 and 1430.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
