Extensions
We specialise in creating additional living spaces through rear, side, and front extensions. Our projects include installing aluminium bi-folding doors, roof lights, and structural steels. Extensions are completed under permitted development rights where possible, with minimal disruption to homeowners.
Loft Conversions
Our loft conversions transform unused spaces into functional rooms, including bedrooms, ensuites, and home offices. Projects typically take 10-12 weeks, with structural upgrades, insulation, and plumbing/electrical installations handled by our qualified team.
New Builds
From foundations to finishes, we manage full new build projects. Our experience includes self-builds and collaborations with architects. We guide clients through planning, recommend local professionals, and ensure projects stay on time and budget.
Garage Conversions
We convert underused garages into practical spaces like home offices, gyms, or guest bedrooms. Projects are completed in 3 weeks where possible, with insulation, electrical work, and structural adjustments tailored to client needs.
Bathroom Installations
Our bathroom installations combine functionality and style, offering bespoke designs from bright white to sophisticated grey schemes. We handle plumbing, tiling, and finishing touches to create relaxing spaces for clients.
