Who We Are
GSB Build was born from a simple conviction: that the finest homes are built by people who genuinely care. Our founder, Geoff Brown, began his career as a tradesman before earning his credentials in project management and construction, giving him a rare understanding of every aspect of a building project.
​
Today, our team of skilled professionals brings that same holistic approach to every project. We combine traditional craftsmanship with contemporary design thinking, and we never lose sight of the fact that we are building someone's home or project.
​
Our work spans the full spectrum of residential and commercial property, from sensitive refurbishments of listed Georgian townhouses to ambitious new-build developments across London and the Home Counties.

Our Services
The bathroom is no longer merely a functional space. It is a sanctuary, a place to restore and refresh. Our luxury bathroom service transforms ordinary bathrooms into exceptional private retreats, drawing on the finest European sanitaryware from Lefroy Brooks, Waterworks and Bisazza, combined with natural stone and bespoke joinery.
Luxury Bathrooms
The commercial environment is a powerful statement of a business's identity. Our commercial fit-out service brings the same craftsmanship we apply to luxury homes to offices, retail spaces, restaurants, hotels and hospitality venues. From Category A shell-and-core fit-outs to fully specified Category B interiors complete with bespoke joinery and AV integration, we manage every detail.
Commercial Fit-Out
A thoughtfully designed extension can add substantial space, value and quality of life to your home. Our service covers rear single and double-storey additions, side returns, wrap-arounds, loft conversions and garden rooms, each designed to integrate seamlessly with the existing character of your property. Our in-house architectural team manages the full planning application process.
Extensions & Loft Conversions
A truly bespoke kitchen is so much more than a collection of units. It is the result of a considered design process balancing beauty with practicality. Our cabinetry is hand-crafted by our master joiners and we work with leading appliance brands including Gaggenau, Miele and Wolf, sourcing countertops in honed marble, Calacatta stone and premium quartz.
Bespoke Kitchens
Our property development service is designed for investors and developers who require a reliable, experienced partner to manage the full development lifecycle. From working with your architect achieving the final outcome, covering single dwellings to multi-unit apartment schemes.
Property Development
A full property refurbishment is one of the most transformative investments a homeowner can make. Our service covers every element of your property, from structural works and damp proofing through to plastering, decorating, new flooring and final dressing. We are particularly skilled in the sympathetic refurbishment of period properties, where preserving original features while introducing modern comforts requires genuine expertise.
Property Refurbishment
Sometimes a property requires more than cosmetic improvement. Our redevelopment service addresses fundamental structural changes, from removing load-bearing walls and reconfiguring floor plans to lowering basement levels and adding new structural elements to unlock a property's full potential. We assist with building regulations, party wall notices and statutory consents.
