Extensions
in West London
We build home extensions across West London - adding valuable living space to your property. From foundations to finishing, we manage the entire project: structural work, brickwork, roofing, plumbing, electrics, plastering and decoration. One team, one point of contact, one build. No coordinating separate contractors or chasing overdue trades.
About This Service
About Our Extensions Service
An extension is the biggest building project most homeowners undertake. We've been building them since 2015 and we understand what makes them succeed: thorough planning, clear communication and reliable tradespeople turning up in the right order. We handle single-storey rear extensions, double-storey side extensions and kitchen extensions. Every build is managed by Vincent from start to finish.

Our Expertise
Planning and Building Regulations
Many single-storey rear extensions fall under permitted development rights and don't need planning permission. For those that do, we guide you through the process. We work with architects and structural engineers to produce the drawings and calculations needed for planning applications and building control approval. We handle the building control inspections throughout the build so you don't have to manage that process yourself.
