Builders in Ickenham

Ickenham was a small village of 329 people in 1901. The Metropolitan Railway opened a halt here in 1905, and the sale and development of much of the Swakeleys estate from 1922 made the village part of Metro-land. The seventeenth-century Swakeleys House still stands.

At the 2021 Census, 87% of households in the Ickenham statistical area lived in houses: 46% semi-detached and 36% detached, the highest detached share of any area we cover. The median semi-detached sale was about £700,000 in the year to March 2026.

Larger plots make two-storey side extensions, generous rear extensions and loft conversions with rear dormers the usual projects. For two-storey side extensions, Hillingdon asks for a 1-metre gap to the side boundary and a 1-metre set-back from the front wall, and won't support one where the roof has already been converted from hip to gable.

The village keeps several older buildings near St Giles' Church, including almshouses built in 1857 for long-serving servants of the Gell household or Ickenham residents.

The Ickenham Village conservation area covers the historic centre, and within it Hillingdon expects extensions to respect the original layout, scale, roof form and materials, with traditional rear dormers rather than larger roof extensions. Elsewhere, policy DMHD 1 limits single-storey rear extensions on detached houses to 4 metres, with flat roofs no higher than 3 metres, and keeps roof extensions to the rear slope, below the ridge and no wider than two-thirds of the roof. Large crown roofs on detached houses are not supported.

Because the borough-wide Article 4 direction removes permitted development for rear extensions deeper than 4 metres, the 8-metre prior approval route available to detached houses in other boroughs doesn't apply here.
