LOFT CONVERSIONS

Service

Expert London
Loft Conversions

BLM Group delivers premium loft conversion services for homeowners across South West London and the capital's most desirable neighbourhoods. From Kingston and Chelsea to Wimbledon and Westminster, we transform underutilised attic space into stunning, functional living areas that add significant value to your home.

We understand that a luxury loft conversion requires more than structural work—it demands spatial intelligence, creative design, and technical expertise in building regulations and planning policy. Whether creating a master suite in Wandsworth, a home office in Islington, or a children's zone in Southwark, our team delivers exceptional craftsmanship with meticulous attention to detail.

Having worked alongside London councils on numerous loft projects, we navigate planning requirements seamlessly—ensuring your conversion is compliant, beautifully finished, and ready to enjoy.

Maximising Space
We unlock your property's hidden potential. From dormer and hip-to-gable conversions to Mansard roofs and Velux installations, we design the right solution for your home's architecture and your lifestyle needs.
Planning & Compliance

Loft conversions in London often require careful navigation of permitted development rights and conservation area constraints. Our team prepares all necessary applications, liaises with council planning officers, and ensures full building regulations compliance.

Quality & Craftsmanship

Every conversion is delivered by our accredited team, holding NICEIC, Gas Safe, and construction accreditations. From structural steelwork to bespoke joinery and premium finishes, we ensure your new space is built to the highest standard.

Our Process
Assess & Design

We begin with a detailed site assessment, measuring your existing loft space and evaluating structural requirements. Our team explores design options, from dormer windows to full Mansard conversions, providing clear guidance on feasibility, planning requirements, and budget. We ensure every solution maximises usable space while maintaining the architectural integrity of homes.

Build & Finish

Once designs are approved, our construction team delivers to a clear project schedule. We coordinate structural works, roofing, insulation, and all internal finishes—including bespoke joinery, luxury bathrooms, and premium flooring. With full building regulations compliance and regular progress updates, your new loft space is delivered on time and to the highest standard.
