GS Renovation designs and builds extensions across Pimlico, from the Regency terraces near the River Thames to the garden-square houses of SW1. With over 30 years in Westminster's period, Georgian and listed properties, we handle groundworks, steel, roofing and full fit-out, and we tell you clearly whether your project is permitted development or needs a planning application.
Rear and side-return extensions in Pimlico
Plots in Pimlico's Regency terraces are often generous at the front yet tight and narrow to the rear, so the most practical additions are rear and side-return extensions that square off the ground floor and open the house to its garden. We dig and pour foundations to suit the ground conditions, install the steel beams that carry the existing rear wall and tie the new roof cleanly into the period elevation behind.
Because so much of Pimlico is white-stucco and sits within a Westminster conservation area, external changes are scrutinised closely, and listed buildings need listed building consent for alterations. We advise honestly on what is achievable at the rear, keep new work sympathetic to the original brick and render, and manage the full build so kitchens, glazing and finishes all come together under one team.
Planning and party walls for Pimlico extensions
Whether your Pimlico extension is permitted development or needs full planning permission depends entirely on the property. Conservation area status, listing and the scale of the work often remove permitted development rights, so many SW1 extensions require an application to Westminster City Council rather than proceeding automatically. We assess your specific house first, then set realistic expectations before any design work begins so there are no surprises at submission.
Extensions here almost always touch a shared boundary, which brings the Party Wall etc. Act into play alongside the building regulations that govern the structure itself. We serve the right notices, coordinate the engineer's steel design and arrange building control inspections at foundation, structure and completion. Keeping planning, party wall and building regs on separate but parallel tracks is how we keep a Pimlico extension moving without costly stops.
