Customer Rating
Many single-storey rear extensions fall under Permitted Development rights and do not need full planning permission. However, rules vary by property type and location. We always check this for you before work begins.
A single-storey extension typically takes 8–14 weeks. A double-storey extension usually takes 14–20 weeks depending on complexity and weather. We provide a full programme before work starts.
Our quotes are fully itemised and cover all labour and materials including groundwork, brickwork, roofing, windows, doors, electrics, plastering and final clean. No hidden extras.
A well-built extension typically adds significant value — often well in excess of the build cost in the Mid Sussex area. Many of our clients recoup their investment and more when they come to sell.
