Service
Luxury Flat
Conversions London
BLM Group delivers premium flat conversion services for homeowners and property developers across South West London and the capital's most desirable neighbourhoods. From Kingston and Chelsea to Wimbledon and Westminster, we transform existing properties into elegant, high-value homes designed for modern London living.
We understand that luxury flat conversions demand more than structural work—they require spatial intelligence, creative design, and technical expertise in planning policy and building regulations. Whether converting a period building in Islington, reconfiguring a maisonette in Southwark, or creating multiple units in Wandsworth, our team delivers exceptional craftsmanship.
Having worked alongside London councils on numerous conversion projects, we navigate planning requirements seamlessly from concept to completion.
Maximising Value
Planning & Compliance
Flat conversions require careful navigation of planning policy, building regulations, and fire safety standards. Our team prepares all necessary applications, liaises with council planning officers, and ensures full compliance throughout.
Quality & Craftsmanship
Every conversion is delivered by our accredited team, holding NICEIC, Gas Safe, and construction accreditations. From structural works to premium finishes, we ensure every home is built to the highest standard.
Our Process
Assess & Design
We begin with a detailed assessment of your property's potential. Our team develops design concepts that balance spatial efficiency with aesthetic appeal, providing clear guidance on feasibility, planning requirements, and budget. We manage all applications, ensuring your project secures the necessary approvals efficiently.
Convert & Deliver
Once designs are approved, our construction team delivers to a clear project schedule. We coordinate structural works, mechanical and electrical installations, and all internal finishes, from bespoke joinery to premium kitchen and bathroom specifications. With full building regulations compliance and regular updates, your converted property is delivered to the highest standard.
