GS Renovation designs and builds house extensions throughout Addiscombe, working with the bay-fronted Victorian and Edwardian terraces and their rear closet wings and side returns that define CR0. Over more than 30 years in Croydon we have handled everything from a modest kitchen extension to a full wrap-around, foundations to finish.
Side-return and rear extensions in Addiscombe
The side return beside the closet wing is the classic space to claim on an Addiscombe terrace. Filling it in widens a cramped galley kitchen into a proper open-plan kitchen-diner, and it is usually paired with a rear extension to push out towards the garden. We dig and pour the foundations, allowing for the trees around Lloyd Park and any drains running along the boundary.
Opening the back of the house into the new footprint means removing the original rear wall, so a steel beam sized by a structural engineer carries the load above. We build the walls, tie the new roof into the existing slope, install rooflights over the kitchen and fit the whole space out. Party wall notices are served where we build up to the shared boundary with the neighbour.
Planning and permitted development in CR0
Whether your Addiscombe extension needs a planning application or falls under permitted development depends on the property and its history. Many single storey rear extensions on these terraces proceed under permitted development within the size limits, while double storey work, anything to the side elevation or a home that has already been extended often needs a full application to Croydon Council. We advise honestly on which route applies before you commit.
Either way the build must meet building regulations, which is separate from planning and covers the foundations, the steel, insulation, drainage and fire safety. We prepare the drawings, submit to Croydon Council where permission is required, arrange a lawful development certificate where it is not, and book the building control inspections so your Addiscombe extension is signed off correctly.

Addiscombe families choose GS Renovation because one team takes the extension from the first foundation trench to the last coat of paint. We know Croydon Council's process, when permitted development applies and when it does not, how to size the steel and how to keep a side-return build tidy while you still live in the house. Thirty years of local experience backs it.
