Builder & Building Contractor — Windsor
Builders in Windsor For Home Extensions, Renovations and Structural Work
Windsor's housing stock reflects its long history as a royal town. Victorian and Edwardian terraces fill the streets close to the town centre and station, while post-war semi-detached development in Dedworth, Clewer North, and Clewer East produced the majority of the town's family homes. These 1950s–70s semis and link-detached properties sit on typically modest plots in the town but on more generous ones towards the Dedworth Road corridor. Larger detached homes appear in Oakley Green and along the roads towards Datchet. The proximity to the castle and Great Park maintains elevated property values across the town.
Single storey kitchen extensions dominate demand — particularly on the post-war semis in Dedworth and Clewer where galley kitchens opening onto compact rear gardens are ripe for transformation. Victorian terrace owners near the centre regularly request side-return extensions or rear additions. Loft conversions are popular on the larger 1960s and 1970s estate houses where there is sufficient roof height. Windsor's consistently high property values make extension investment attractive across all property types.

Kitchen Extension in Windsor
A kitchen extension is the most popular and highest-value project we deliver in Windsor. Whether you want to extend the rear of the house to open the kitchen onto the garden, fill a side return, or create a full L-shape open-plan kitchen/dining space, we manage the full process from planning assessment through to Building Regulations Completion Certificate.
Windsor has several designated conservation areas, most notably in the town centre and Windsor Great Park fringe. Works within these areas typically require full planning permission rather than permitted development, and the Royal Borough expects materials and design to be sympathetic to the townscape. Some streets also adjoin Crown Estate land, which adds complexity to boundary treatment. We always assess the conservation area position at the initial site visit before work is priced.
