Extensions & Renovations, Designed Around How You Live
Most people don't set out wanting a building project. They want more space for a growing family, a layout that finally works, or the forever home they've always pictured. Our job is to make that happen. IN Construction Ltd specialises in house extensions and full home renovations across Surrey, turning the home you have into the one you actually want to live in.
With over 15 years' experience and a skilled in-house team, we manage every stage under one roof, from design and planning to structural work and the finishing trades that make the difference. From Ashford and Staines-upon-Thames to Walton-on-Thames, Shepperton, Esher and Cobham, we've earned a reputation for high-quality workmanship, clear communication and homes finished to a standard our clients are proud to show off.
