Award-Winning Design & Build in Enfield
Enfield offers something that much of inner London cannot: space. The properties across EN1, EN2 and EN3 tend to have wider frontages, deeper gardens and more generous plots than their equivalents closer to the centre. That means bigger extensions, more ambitious loft conversions, and building projects that genuinely transform how your family lives — at a fraction of the cost of moving to a larger home.
LCCL Construction serves Enfield Town, Bush Hill Park, Grange Park, Ponders End, Enfield Highway and the surrounding areas from our base in Finchley N3. We have been building across Enfield for over 20 years, and we understand this area in a way that a London-wide firm sending a team up from South London simply cannot.
We know that Bush Hill Park’s distinctive Edwardian estate has its own conservation area. We know that Grange Park’s detached homes have wider plots that suit wraparound extensions. We know that Enfield Council’s planning approach differs from Barnet’s. With LCCL, you get a full design and build company — architecture, structural engineering, planning, construction and project management from one team.

- HOUSE EXTENSIONS
House Extensions in Enfield
Enfield’s generous plot sizes make it one of the best areas in North London for house extensions. Where a Victorian terrace in Islington might struggle to accommodate a 4-metre rear extension, a semi in Bush Hill Park can comfortably take a 6-metre extension plus a side addition. The wider-fronted properties in Grange Park suit wraparound extensions that would be impossible on a narrower plot. Even the more modest terraces in Ponders End typically have deeper gardens than inner London equivalents.
The financial case for extending in Enfield is compelling. Moving from a three-bed to a four-bed semi in EN1 or EN2 typically costs £100,000 to £150,000 more in purchase price alone, plus stamp duty, legal fees, moving costs and the disruption of uprooting your family. A well-designed extension or loft conversion can add the same space for a fraction of that cost.
Extension Types for Enfield Properties
Single-Storey Rear Extensions — The most common project across Enfield. Permitted development allows up to 6 metres for detached houses and 4 metres for semis and terraces. Kitchen-diner extensions with bifold doors to the garden. Costs: £48,000 to £85,000.
Wraparound Extensions — Combining side and rear for maximum ground-floor footprint. Particularly effective on the wider semis in Bush Hill Park and Grange Park. Costs: £72,000 to £110,000.
Double-Storey Extensions — The wider plots across Enfield make double-storey additions particularly viable. Adds living space downstairs and bedrooms upstairs. Costs: £95,000 to £175,000.
Single-Storey Front Extensions — Where front gardens are large enough, particularly in EN2 and EN3, a front extension or substantial porch can add a useful room. Less common in London but achievable in Enfield. Costs from £30,000.
What Is Included in Every Extension Quote
All prices include: in-house architectural design, structural engineering, planning applications to Enfield Council where required, all construction labour and materials, project management, building control via LABC, and a 10-year LABC warranty.

- LOFT CONVERSIONS
Loft Conversions in Enfield
Enfield’s housing stock includes a high proportion of 1930s and interwar properties with generously sized roof spaces — bigger than you would typically find in inner London. Bush Hill Park’s semis, Grange Park’s detached homes and the varied housing across Enfield Town all respond well to loft conversion, adding valuable bedroom and bathroom space that can increase your property value by 15 to 25 percent.
Most loft conversions in Enfield qualify under permitted development rights. Properties within the Bush Hill Park Conservation Area or Enfield Town Centre Conservation Area face additional restrictions, but rear dormers and sympathetically designed conversions are generally achievable. Our architects handle all planning requirements.
Loft Conversion Types for Enfield Properties
Hip-to-Gable Conversions — The ideal choice for the 1930s semis across Bush Hill Park and Grange Park. Converting the hipped roof to a vertical gable wall adds 30 to 40 percent more usable space. Combined with a rear dormer for maximum room. Costs: £48,000 to £70,000.
Dormer Conversions — Rear flat-roof dormers suit all property types across Enfield. Most qualify under permitted development. Creates a spacious bedroom with en-suite. Costs: £42,000 to £62,000.
L-Shaped Dormers — Combines rear and side dormers on semis for maximum space. Two bedrooms or a large master suite. Costs: £55,000 to £75,000.
Mansard Conversions — Premium roof replacement creating near-full-height rooms. Suits the Victorian terraces around Enfield Town where roof pitches are steeper and the Edwardian character suits a mansard profile. Requires planning. Costs from £62,000.
What Is Included in Every Loft Quote
All prices include: in-house architectural design, structural engineering, scaffolding, all construction including steelwork and dormer or gable build, staircase, insulation, plastering, electrics, en-suite plumbing, building control via LABC, project management, and a 10-year LABC warranty. No hidden extras. Call 020 8037 7332.
- RENOVATIONS
Renovations in Enfield
Enfield’s housing stock is more varied than many people realise, and each property type brings different renovation opportunities. The Victorian and Edwardian terraces near Enfield Town station have characterful period layouts with separate reception rooms and narrow kitchens that benefit from structural reconfiguration into open-plan family spaces. Many of these properties also have original features — cornicing, fireplaces, panelled doors — that deserve preservation during renovation.
The distinctive Edwardian estate in Bush Hill Park features bay-fronted semis and terraces with solid construction and good proportions, but often with dated kitchens, bathrooms and heating systems that are overdue for comprehensive upgrading. The interwar and postwar housing across Grange Park and Ponders End may need rewiring, replumbing and complete modernisation.
LCCL handles all of this. Our renovation service covers structural alterations including load-bearing wall removal, kitchen and bathroom installations at every specification level, rewiring, replumbing, boiler and heating upgrades, plastering, decoration, tiling, flooring, and complete interior fit-outs. One project manager coordinates every trade — you deal with one person, not a dozen contractors.
Typical renovation costs in Enfield: kitchen renovation £22,000 to £50,000, bathroom renovation £10,000 to £22,000, structural wall removal with RSJ £5,000 to £10,000, whole-house refurbishment from £75,000. Detailed quotes — no day rates, no open-ended estimates. Final costs confirmed once designs are agreed.
- ARCHITECTURE
In-House Architecture in Enfield
Enfield Council has its own planning policies, design expectations and application processes that differ from neighbouring boroughs like Barnet and Haringey. Our in-house architects submit to Enfield’s planning department regularly and understand the council’s approach to householder applications, conservation area proposals, and the specific expectations that apply to the Bush Hill Park estate.
The integrated design and build model means our architects design with construction costs and buildability in mind from day one. There is no separate architect producing drawings that turn out to be over budget or unbuildable. The people who design your project are part of the same team as the people who build it — which eliminates the communication breakdowns that plague the traditional architect-then-builder approach.
Every Enfield project includes: measured survey, concept designs, 3D visualisations, construction drawings, planning applications or Lawful Development Certificates to Enfield Council, structural engineering, and LABC building regulations submissions. All included in your quote — no separate architect fees, no hourly rates.
