Double Storey Extensions in Sunningdale
Sunningdale is one of the most prestigious villages in the South East, sitting between Ascot and Virginia Water in the Royal Borough of Windsor and Maidenhead. The village is predominantly composed of large detached properties — Edwardian Arts and Crafts houses, substantial inter-war homes in the 1920s and 1930s Surrey-vernacular style, and more recently built high-specification modern villas. Many properties sit on plots of half an acre or more, accessed via private roads. Values consistently rank among the highest in Berkshire, and the resident profile skews towards established professionals and international buyers seeking proximity to Heathrow. At this end of the market, construction quality and clear communication matter more than ever — get in touch and we'll walk you through everything before you commit to anything.

What Affects Cost in Sunningdale
Extension costs in Sunningdale vary based on: footprint and height; ground conditions and foundation depth; structural steel required; glazing specification (bi-folds, rooflights, lanterns); kitchen or bathroom specification; site access; and conservation area design requirements where applicable.
Sunningdale's roads include properties within or adjacent to conservation areas, and several private roads carry Article 4 directions that remove standard permitted development rights. The Royal Borough of Windsor and Maidenhead takes a careful approach to extensions that affect the character of the village streetscape. Some properties sit close to the Green Belt or within the Surrey Hills buffer zone. Large plots can mean complex drainage diversion and longer groundworks phases. We check every address individually before quoting.
