Luxury Home
Extensions London
BLM Group delivers premium home extension services for homeowners across South West London and the capital's most desirable neighbourhoods. From Kingston and Chelsea to Wimbledon and Westminster, we create elegant, functional spaces that transform how you live in your home.
We understand that luxury extensions demand more than additional square footage—they require spatial intelligence, architectural vision, and technical expertise in planning and building regulations. Whether creating a kitchen extension in Wandsworth, a side return in Islington, or a double-storey addition in Southwark, our team delivers exceptional craftsmanship.
Having worked alongside London councils on numerous extension projects, we navigate planning requirements seamlessly from concept to completion.
Bespoke Extensions
Planning & Compliance
Home extensions require careful navigation of permitted development rights and planning policy. Our team prepares all necessary applications, liaises with council planning officers, and ensures full building regulations compliance.
Quality & Craftsmanship
Every extension is delivered by our accredited team, holding NICEIC, Gas Safe, and construction accreditations. From foundations to finishes, we ensure your new space is built to the highest standard.
Our Process
Design & Plan
We begin by understanding your vision and assessing your property's potential. Our team develops design concepts that balance aesthetic ambition with practical considerations, providing clear guidance on feasibility, planning requirements, and budget. We manage all applications, ensuring your project secures the necessary approvals efficiently.
Build & Complete
Once designs are approved, our construction team delivers to a clear project schedule. We coordinate structural works, roofing, glazing, and all internal finishes—from bespoke kitchen installations to premium flooring and lighting. With full building regulations compliance and regular updates, your new space is delivered on time and to the highest standard.
