- HOUSE EXTENSIONS
House Extensions in Crouch End — Edwardian Homes, Modern Space
Crouch End's Edwardian terraces and semis are ideally suited to extension work. Many properties have side access and deeper gardens than inner London equivalents, creating scope for rear extensions, side additions, and wraparound layouts. The hilly terrain means some properties also have lower ground floors with development potential.
Extension Types for Crouch End Properties
Rear Extensions — The most requested project in Crouch End. Kitchen-dining extensions with bifold doors to the garden. Permitted development allows 3 metres for terraces, 4 metres for semis outside conservation areas. Typical costs: £50,000 to £85,000.
Side Return Extensions — Many Edwardian terraces in N8 have side passages that can be incorporated. Transforms the ground-floor layout. Typical costs: £40,000 to £62,000.
Wraparound Extensions — Combining side and rear for maximum ground-floor space. Particularly effective on the wider-fronted Edwardian semis. Typical costs: £65,000 to £108,000.
Double-Storey Extensions — For semis and detached properties with sufficient plot size. Adds living space and bedrooms. Typical costs: £95,000 to £175,000.
What Is Included
All prices include: architecture, structural engineering, planning applications to Haringey Council, all construction, project management, building control via LABC, and 10-year LABC warranty. All-inclusive quote. Call 020 8037 7332.
- LOFT CONVERSIONS
Loft Conversions in Crouch End — Edwardian Roofs, Extra Bedrooms
Crouch End's Edwardian properties have generous roof spaces with steeply pitched roofs and good ridge heights. The semi-detached properties typically have hipped roofs ideal for hip-to-gable conversions, while the terraced properties suit rear dormers and mansard extensions. Most conversions outside the conservation area qualify under permitted development.
Loft Conversion Types for Crouch End Properties
Hip-to-Gable Conversions — The ideal choice for Crouch End's Edwardian semis. Extending the hipped roof to a gable wall adds 30 to 40 percent more usable space. Combined with a rear dormer. Costs: £52,000 to £75,000.
Rear Dormer Conversions — Popular for terraced properties. Flat-roofed rear dormers creating spacious bedrooms with en-suites. Costs: £48,000 to £68,000.
Mansard Conversions — Maximum space for terraces. Requires planning permission. Costs: £65,000 to £90,000+.
L-Shaped Dormers — For end-of-terrace and semi-detached properties. Costs: £58,000 to £80,000.
What Is Included

- RENOVATIONS
Renovations in Crouch End — Updating Edwardian Homes
Crouch End's Edwardian properties are solidly built and generously proportioned, but many still have separate front and rear reception rooms, dated kitchens, and original bathroom suites. A well-planned renovation preserves the Edwardian character — bay windows, ceiling roses, original fireplaces, tiled hallways — while delivering modern functionality.
Typical costs: kitchen renovation £26,000 to £55,000, bathroom renovation £12,000 to £26,000, structural reconfiguration £6,000 to £12,000, whole-house refurbishment from £90,000 upward. Detailed quotes provided. Final costs confirmed once designs and structural requirements are agreed.
