Builders in Ruislip

Ruislip's growth followed the Metropolitan Railway's extension from Harrow, whose new station at Ruislip opened on 4 July 1904; a new urban district was created in anticipation of the population growth. The old village around the parish church, Manor Farm and the High Street survives at the centre, surrounded by twentieth-century suburbs.

At the 2021 Census, 77% of households in Ruislip, Ruislip Manor, Ruislip Gardens and West Ruislip lived in houses: 30% semi-detached, 28% terraced and 20% detached. Median semi-detached prices were about £610,000 to £800,000 in the year to March 2026.

The high share of terraced houses means many projects here are compact rear extensions and rear dormer lofts, while the larger semi-detached and detached houses leave more room for side and two-storey extensions.

Ruislip's landmarks include Ruislip Lido, a former reservoir that is now public parkland, and Manor Farm, a settlement dating from the ninth century that is now a local heritage site.

Ruislip has two conservation areas: Ruislip Village, around the historic centre, and Ruislip Manor Way. Inside them, Hillingdon expects extensions to follow the plan and style of the original building, flat-roofed single-storey extensions to have a parapet, and roof extensions to take the form of traditional rear dormers.

Across Ruislip, policy DMHD 1 limits single-storey rear extensions on semis and terraces to 3.3 metres on plots up to 5 metres wide and 3.6 metres on wider plots, with flat roofs no higher than 3 metres and pitched roofs no higher than 3.4 metres. The borough-wide Article 4 direction means anything projecting more than 4 metres needs a full application.
