The street is notable for its social housing blocks. These are of two phases. The first, facing Regency Street and Page Street were commenced in 1902 and were considered of sufficient significance for the Prince of Wales to ceremonially lay the foundation stone in 1903. They are of red brick, similar in design to the nearby Pimlico Estate developed by the
London County Council and the architects were
Nathan S. Joseph and
Charles James Smithem. The second phase were designed by Sir
Edwin Lutyens who was commissioned as consultant to the
Grosvenor Estate, freeholder of the land, who granted a 999-year lease to Westminster and donated £120,000 towards the cost, provided the site was used for "housing for the working class," as part of the Westminster Housing Scheme. The flats have a conventional
tenement plan and have striking and unusual chess-board facades of rectangles in buff-grey brick and rendered panels, covering the entirety of their outer facades. Accessed by balconies to the courtyard elevations, in the manner of much social housing of the period, the blocks were built in 1928–30 and front much of the western end of Page Street. The U-shaped internal courtyards face Page Street on the N side but are turned away from the street on the S side. The courtyards are narrower than most of those of
London County Council blocks of the period, something which was partly mitigated by the partial demolition of Tothill and Rogers Houses in about 1970, due to war damage, which created a recreational space. As a result of this partial demolition the remaining Lutyens blocks and their lodges and gates were all
Listed as early as 1970, when protection of social housing scheme was highly unusual. The landscaped areas are entered through wrought iron gates beside classical
pavilion lodges, in typical Lutyens style; the lodges are in Portland stone with grey-buff brick under pyramidal roofs and were formerly small shops and a management office, but are now in a variety of uses. The estate combines an unusual mixture of balcony access tenement architecture and the Lutyens detailing more often associated with the architect's country house architecture. It was Lutyen's only social housing design. ==Other buildings==
