Home Renovation Winchmore Hill

GS Renovation refurbishes whole houses and whole flats across Winchmore Hill, taking interwar semis and substantial Edwardian properties back to the fabric and rebuilding them properly. One team runs the structure, the rewire, the plumbing, the plaster and the finishes to a single programme, so trades follow each other in the right order instead of queueing on the pavement.

In Winchmore Hill, a full house refurbishment typically costs £40,000 to £150,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Winchmore Hill: we carry the structure, services and finishes as one contract.

The two rooms that cost the most have their own pages, with prices: kitchen renovation in Winchmore Hill and bathroom renovation in Winchmore Hill. In the 72% of homes here that are houses, moving the kitchen usually means opening up the back of the ground floor, which is structural work.

What a full refurbishment finds in an N21 period house

Three things come up in nearly every Winchmore Hill period house we strip out. Rewiring the solid walls of an Edwardian house means chasing brick rather than dropping cables down a cavity, so the routes have to be planned with the plasterer before the electrician starts. The suspended ground floor is usually under-ventilated, with airbricks painted over or buried by a raised path, which we clear before anything is insulated. And the lath and plaster is a genuine decision: sound lath holds mouldings and takes the character with it if it goes, while blown lath that has lost its key is a false economy to patch.

The other recurring find is the legacy of an earlier conversion. Houses divided into flats decades ago tend to have services run wherever was easiest, waste pipes clipped across elevations, meters in cupboards under the stairs and fire doors that were never fire doors. Where a property is being brought back to a single family house we untangle all of that, and where a house is staying as flats we improve the separation between them properly, with sound and fire resistance to the floor between rather than a new carpet and hope.

Housing in Winchmore Hill

Winchmore Hill has around 3,160 homes on the Council Tax list: 16% post-war, 49% interwar and 34% predate 1919, with 28% flats and 72% houses. A semi in Winchmore Hill usually has side access, and 46% of homes here are semi-detached.

Insulating solid walls without trapping damp in Winchmore Hill

In Winchmore Hill 34% of homes were built before 1919, with solid brick walls that dry out through both faces. Insulating the inside of such a wall with a foil backed board stops that drying, and damp then collects at the cold face behind it, where it can reach joist ends built into the wall. Materials that let moisture pass, such as wood fibre board finished with lime plaster, avoid that. Where a renovation strips or replaces a large part of an external wall's plaster, Part L can require the wall to be insulated, so the choice has to be made deliberately.

Insulating outside changes the look of the house, and in the Winchmore Hill Conservation Area that is a planning question. Planning Data records an Article 4 direction area covering it under the Enfield Borough Conservation Areas Article 4(1) Direction 2003. Cladding or render is outside permitted development in any conservation area, and new window reveals on an elevation the direction covers may need an application too, so check before specifying. Interwar houses built between 1919 and 1939, 49% of homes here, often have a cavity instead, and the cavity is checked with a borescope for existing fill, rubble and corroded ties before anything is injected.

Sequencing, consents and conservation area windows

The programme runs structure first, then first fix electrics and plumbing, then plaster, then joinery, kitchen and bathrooms, then second fix and decoration, with an Enfield building control inspection at each stage that will later be hidden. New circuits are notifiable under Part P and are certified by a registered electrician, or notified to building control. Where the layout changes and a wall comes out, the engineer we appoint designs the beam and building control signs it off. None of this needs planning permission because it is all inside the building, although a listed building would need listed building consent for internal alterations.

Windows are the exception, and around Winchmore Hill Green they matter. Original timber sashes are one of the features the conservation area designation exists to protect, and if the property is a flat or listed the controls are tighter still. Repairing and draught proofing existing sashes, or replacing like for like in timber with slim double glazing, is normally the route that gets approved; plastic frames on a principal elevation are normally the route that does not. We check with Enfield planning first and build to what is actually consented.
