Why Choose LCCL Construction for Your Home Project?

Award-Winning Quality


LCCL Construction won the LABC Awards Regional Winner 2024 for Best Residential Extension in London. The LABC (Local Authority Building Control) Awards recognise the highest standards of design, construction and building regulations compliance. This is not a self-awarded badge — it is judged by independent building control professionals who inspect the quality of work first hand.


Over 200 Verified Reviews Rated 4.7 out of 5


With more than 200 reviews across Google, Houzz, Trustpilot and Reviews.io, LCCL Construction is one of the most reviewed construction companies in North London. A 4.7 out of 5 rating across 200+ reviews demonstrates consistent quality and customer satisfaction over many years and many projects.


Over 20 Years of Experience


LCCL Construction has been designing and building loft conversions, house extensions and home renovations across London and Hertfordshire for over 20 years. This experience means we have worked on virtually every property type — Victorian terraced houses, Edwardian semis, 1930s detached homes, modern builds and period properties in conservation areas. We know what works and what to avoid.


One Construction Company Does Everything


Our design and build service means one company handles your entire project from start to finish: initial consultation, measured building survey, architectural design, planning permission, building regulations, structural calculations, party wall agreements, all construction work, electrics, plumbing, plastering, decoration and building control sign-off. One point of contact, one contract, one price. No gaps between stages, no communication problems between different professionals.


LABC Registered Partners and NFB Members


We are LABC Registered Partners, meaning we work directly with local authority building control to ensure every project meets the highest standards. We are also members of the National Federation of Builders, the UK construction industry’s leading trade body.


Optional 10-Year LABC Structural Warranty


Every project comes with the option of a 10-year LABC structural warranty, giving you complete peace of mind and protecting the investment in your home.


Transparent Pricing


We provide detailed written quotes before any work begins. Our pricing is transparent with no hidden costs. You know exactly what you are paying for and what is included.


Based in Finchley, Serving London and Hertfordshire


Based at 3rd Floor, Hathaway House, Popes Drive, Finchley, London N3 1QF, we serve all of London and Hertfordshire. Our local knowledge of planning policies, building regulations and property types across North London, Central London, South London, West London and Hertfordshire is unmatched.
