SOUTH LONDON BUILDERS · FAMILY-RUN SINCE 2014

We build homes the way they used to be built — only better. Since 2014, LMDEC Ltd has delivered loft conversions, house extensions and full house refurbishments across South and West London. Our director and project manager coordinate site teams and specialist trades, with a clear scope and one point of contact throughout your project — and a fixed-price quote within 48 hours of our site visit.

Most home renovations stall because of poor communication and uncoordinated trades. At LMDEC, we eliminate that frustration. We handle all general trades—demolition, structural steel, carpentry, plastering, custom tiling, and luxury decorating—with our dedicated, in-house team. Specialist installations are managed alongside certified Gas Safe and NICEIC subcontractors. You get one project manager, one fixed-price contract, and one clear standard of quality.

— Our approach
One team, one project manager, one number to call.
Most renovations go wrong in the gaps — between trades, between drawings and reality, between what was quoted and what’s actually needed. We close those gaps by keeping the core trades in-house — carpentry, plastering, tiling, decorating — with gas and electrics by our regular Gas Safe and NICEIC registered subcontractors. No coordinating five firms who’ve never worked together before.
You speak to one person from quote to handover — me or our project manager. We give fixed-price quotes, and if the scope genuinely changes, we tell you before the work happens, not after. And we don’t leave site until snagging is complete.

— Where we work
We’re South London builders — and this is where we work.
We’re based in South Croydon and most of our work happens within thirty minutes of our office. After more than a decade of renovating South London homes, we’ve come to know the local councils, the planning officers, the period properties, and the typical extension constraints that come with Victorian and Edwardian housing stock.
Planning a project? Use our free London renovation cost estimator, explore loft conversions across South London — 12 area guides with council rules and Article 4 directions — or see house extensions and full house refurbishments.
That local knowledge matters. We know which planning department to call about lofts in Wandsworth, how the conservation rules apply in Richmond, what the typical Edwardian floor plan looks like in Wimbledon, and where to source matching original tiles for restorations in Kensington & Chelsea. It’s not just renovation — it’s renovation done right for your area.
We currently take on a maximum of three projects at a time. If we say yes to your job, you get our full attention from quote to handover — never juggled against five others.
