GSM Builders Ltd are builders in Ruislip and across the HA4 area including Ruislip Manor, Ruislip Gardens, South Ruislip, Eastcote and Ickenham. As a Hillingdon-based company (our yard is in Hayes, about 15 minutes down the A437) we know the local housing, the local planning department and the local suppliers.
Metroland houses and what they can become
Ruislip is classic 1930s “Metroland”: wide tree-lined roads of semi-detached and detached houses with hipped roofs, bay windows and long gardens, built when the Metropolitan and Piccadilly lines arrived. Ninety years on, most families want more space than the original layout gives them, and these houses are among the easiest in London to extend.
The projects we are asked for most in Ruislip are hip-to-gable loft conversions with a rear dormer (often adding a large bedroom, en-suite and eaves storage), wrap-around extensions that combine a rear and side extension into one open-plan kitchen, dining and family room, and double-storey side extensions that add a bedroom above a new utility or garage space. We also carry out a lot of full refurbishments for buyers modernising a house that has not been touched since the 1970s.
Planning in Ruislip and Hillingdon
Planning is handled by the London Borough of Hillingdon. Ruislip Village, Eastcote Village and parts of Ickenham are conservation areas, and Ruislip Woods and the Lido sit within the green belt, so a small number of streets have tighter rules. Elsewhere, single-storey rear extensions up to 3 m (or 6 m with prior approval) and loft conversions up to 50 m³ on a semi are normally permitted development. Hillingdon also allows householders to apply for a Lawful Development Certificate, which we recommend for any loft or extension so you have paperwork proving the work was lawful when you sell.
