GS Renovation designs and builds extensions across Hornchurch, where 1930s semi-detached and interwar houses sit on generous plots that suit rear and side additions. With over 30 years in RM11 and the surrounding Havering suburbs, we handle foundations, steelwork, roofing and full fit-out, and guide you through permitted development or a planning application to Havering Council.
Rear and side-return extensions in Hornchurch
The wide plots that characterise Hornchurch give real scope for extending. A single storey rear extension across the back of a 1930s semi creates the open-plan kitchen-diner most families want, while the space down the side of a detached or semi-detached house suits a side-return or wrap-around that squares off the ground floor. We begin with trial holes and properly designed foundations, because interwar houses were built with shallower footings than modern regulations require.
From there we form the openings with engineer-designed steel beams, build up in matching brick, tie in the new roof and install the glazing, then complete the internal fit-out. Because a rear extension of a Hornchurch semi typically involves work near or on the party wall, we serve the correct notices to neighbours. Every element is inspected by Havering building control, from foundations and drainage to insulation and the finished structure.
Permitted development or planning in RM11
Many single storey rear extensions on Hornchurch houses fall under permitted development, meaning they can proceed without a full planning application provided they stay within the size, height and boundary limits the rules set. On the larger interwar plots this often gives generous scope. We assess your property against the current criteria and, where it qualifies, recommend a lawful development certificate from Havering Council to confirm the position in writing.
Double storey extensions, wrap-arounds, work that fronts the street or anything beyond permitted development limits will need a full planning application to Havering Council, and we prepare and manage that submission for you. Whichever route applies, building regulations still govern the structure, so foundations, beams, insulation, fire safety and drainage are inspected regardless. We are clear from the outset about which consent your specific project needs so there are no surprises.
