GS Renovation builds extensions in and around Bermondsey, from the pockets of houses near Borough to family homes reaching toward Camberwell and Dulwich. With over 30 years in SE16 and the wider borough, we handle foundations, steelwork, roofing and fit-out, and we tell you honestly whether your project is permitted development or needs planning permission.
Rear and side-return extensions in Bermondsey
Where Bermondsey gives way to the terraced streets around Borough and Camberwell, the classic project is a rear or side-return extension that squares off the plot and opens the ground floor to the garden. We dig and pour foundations to suit the ground, install the steel beams the new opening needs and tie the new roof into the existing structure, then fit out the space with services, glazing and finishes.
Many single-storey rear extensions fall under permitted development, but that is never guaranteed in Bermondsey. Corner plots, flats, conservation-area coverage and previous extensions can all remove permitted development rights, meaning a full planning application to Southwark Council. We assess your specific property first, then handle the drawings, the planning route where required, and the building regulations approval that every extension needs.
Extending leasehold homes across SE16
Much of Bermondsey's stock is leasehold flats in warehouse conversions and new-build blocks, where a conventional garden extension is rarely possible and structural change is limited by the lease. Here we focus on what can be achieved within the demise, such as reconfiguring internal space or, in ground-floor maisonettes with outdoor rights, a modest addition agreed with the freeholder and managing agent.
Any external alteration in these blocks needs the freeholder's licence to alter, building-management consent and, in many cases, planning permission from the council because the change affects a shared building. We manage that consenting process alongside the construction, work to the party wall award where a boundary or shared wall is involved, and keep the acoustic and fire separation between flats intact throughout.
