Single Storey Extensions in Windsor
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. Whatever your budget, this page and our team's contact details are the quickest way to get a straight answer — customers tell us they'd rather get in touch and ask than guess at what's possible.
