Building in Winchmore Hill: a local guide to renovation, planning and getting it right

The housing stock in Winchmore Hill

Edwardian and 1930s family houses, larger detached houses around the Green, and Victorian cottages on the older lanes.

Winchmore Hill and neighbouring Grange Park hold some of North London's most substantial family houses. The Green conservation area sits at the heart of the village, and the surrounding streets run to large detached houses that benefit from proper refurbishment and considered extension. Our Enfield-based team works in N21 constantly.

Most of our Winchmore Hill instructions come from owners of winchmore hill green conservation area houses, grange park mock-tudor detached houses, bush hill park edwardian houses, and from clients moving between Enfield, Southgate, Palmers Green, Grange Park who already know the type of building they are buying into.

Planning and consent with the London Borough of Enfield

The Winchmore Hill Green Conservation Area protects the older houses around the Green and the lanes leading off it.

Outside the conservation area many schemes are achievable under permitted development, which shortens the route to site considerably.

Our approach is the same every time: establish the constraints before anything is designed, agree the route to consent with the client, and price the job against the scheme that will actually be approved rather than the one that looks best on a first sketch.

The work we carry out in Winchmore Hill

The bulk of our Winchmore Hill work is rear and wraparound extensions, loft conversions, roof renewal and whole-house modernisation.

Whole-house refurbishment. Strip-back refurbishment of Winchmore Hill and Grange Park family houses, delivered by our directly employed local team.

Side and rear extensions. Substantial family extensions designed under LB Enfield planning, with quality drawings and clean delivery.

Loft conversion. Dormer and mansard loft conversions creating additional bedrooms and en-suites for growing families.

Access, neighbours and running a tidy site

Side access on most houses means muck away and materials avoid the interior entirely.

Every trade on a Winchmore Hill project is directly employed by Ushii. There is no chain of outside firms to chase, no pricing surprises when a trade turns up, and one team responsible for the work from strip-out to snagging.

Realistic programmes in Winchmore Hill

Three to six months for an extension and loft, five to nine for a whole house.

Those figures assume consent is in place and decisions are made when they are asked for. The single biggest cause of delay on prime London projects is not construction, it is a client decision waiting on a specification that was never finalised. We front-load those choices into the programme so they are made calmly rather than under pressure.
