As a result of many internal alterations over the years, the three terraced houses are internally a single complex; one can walk from number 11 to number 10, via an internal connecting door, without using the street doors. The [[Cabinet Office]] on Whitehall is also directly connected to these at its rear making up an executive office of the prime Minister and senior [[Privy Councillor]]s.<ref>A. Seldon & J. Meakin (2016) ''The Cabinet Office, 1916-2016: The Birth of Modern Government'', London: Biteback, Chapter 6</ref>

The terraced house was one of several built by Sir [[Sir George Downing, 1st Baronet|George Downing]] between 1682 and 1684 to designs by [[Christopher Wren]]. It was altered c. 1723–35; refaced c. 1766–75 by [[Kenton Couse]] and with early C.19 alterations. Along with Number 10, it underwent a major reconstruction by [[Raymond Erith]], 1960–64.<ref>The Architect and Building News, 25 December 1963</ref> Despite reconstruction, the interior retains a fine staircase with carved bracket tread ends and three slender turned balusters per tread. The fine Dining Room of 1825–26 is by Sir [[John Soane]].<ref>{{cite web|url=http://collections.soane.org/object-m546|title=Model for the domical ceiling to the eating-room at No. 11 Downing Street, designed by Sir John Soane|publisher=Sir John Soane's Museum|access-date=20 October 2022}}</ref>
