Alexandra Road is London terrace house with the design of high-density public housing. Alexandra road represents the application of the terraced theme on an enormous scale.
The long site is consisted of three parallel rows of dwellings. Two rows of terraced apartments are aligned along the tracks with the higher 8 story stepped building designed to block the noise of the trains. A lower, 4-story block runs along the other side of a continuous public walkway that serves both terraced rows of buildings. The third row of building, along the southern edge of the site, parallels another public walkway between this row and the existing earlier buildings of the Ainsworth Estate and defines an open public park between the second and third row of dwellings.
A community center that includes a school, reception center, maintenance facilities and the heating plant mark the entrance to the site from London Road to the west and open to the park areas. The lower buildings contain maisonettes with shared access, terraces, and gardens. Maisonettes also occupy the top two levels of the large slab with entrance from a continuous gallery at the 7th floor. The dwellings in the lower floors in this block are flats that are entered from open stairs serving two dwellings per floor. Parking is located beneath the building along the tracks. Alexandra road received much criticism during and after construction because of enormous cost overruns caused by the complicated construction, unforeseen foundation problems and inflation.
