Comprehensive building services in Rochester including extensions, loft conversions, garden rooms, renovations and roofing.
House extensions are one of the most effective ways to add space, improve layout and increase property value without the cost of moving. At Rochester Builders, we design and build extensions that integrate seamlessly with your existing home.
We construct single-storey, double-storey, rear, side and wraparound extensions, carefully planned to improve flow, maximise natural light and suit modern living. From foundations and drainage to structural steelwork, roofing, glazing and internal finishes, we manage the entire build process.
Every extension is tailored to how you live — whether that’s creating a larger kitchen-diner, a family living space or additional bedrooms — with a focus on long-term durability and comfort.
A loft conversion allows you to unlock unused roof space and transform it into valuable living accommodation. We convert lofts into bright, practical rooms that feel like a natural part of your home.
Each loft conversion begins with a structural assessment to determine the most suitable option. We manage all structural reinforcement, insulation, staircases, electrics and fire-safety requirements, ensuring full compliance with building regulations.
Whether you’re adding a bedroom with en-suite, a home office or flexible living space, our loft conversions are designed to maximise space, light and usability.
Garden rooms provide flexible, independent space without altering your main house. We design and build fully insulated garden rooms suitable for year-round use.
Our garden rooms are ideal for home offices, gyms, studios or quiet retreats and are built using modern construction methods. Insulated walls, floors and roofs, double glazing and electrical installation are included as standard.
A garden room is a fast, efficient way to gain additional space while adding lifestyle benefits and long-term property value.
