Full refurbishments and whole-house renovations in Barnet. Trusted, professional, 30+ years' hands-on experience.
GS Renovation takes on whole-house refurbishments across Barnet, breathing new life into the 1930s semis and interwar houses of Finchley, Hendon and Golders Green. With over 30 years across N2, N3, N12, NW4 and NW11, we manage rewiring, replumbing, replastering and structural changes with one team, sequencing the whole project from strip-out to final decoration.

Many of Barnet's interwar houses still carry their original compartmentalised layout, with small kitchens, separate dining rooms and dated wiring and pipework from decades of piecemeal updates. A full refurbishment lets us reconfigure these rooms for modern life, often knocking through to create open-plan living at the rear while keeping the period character that makes homes around Hampstead Garden Suburb and Mill Hill so sought after.
We strip back to what needs replacing and renew the essentials, a full rewire, new plumbing and heating, fresh plaster and, where the fabric allows, improved insulation. Original features worth saving, such as cornicing, picture rails, panelled doors and cast fireplaces, are protected and restored rather than lost. Everything is brought up to current standards, with kitchen and bathroom electrics notified under building regulations.
The value of a whole-house project is sequence. We plan structural work first, any steel beams or wall removals signed off by building control, then first-fix services, plaster, kitchens, bathrooms, second fix and decoration follow in the right order. Where wall removal touches the wall you share with a neighbour, a common situation in Barnet's semis, party wall notices are served in good time.
One team means one point of contact and no gaps between trades blaming each other. We coordinate electricians, plumbers, plasterers, joiners and tilers on a single programme, keeping the site tidy and the work moving whether you stay put or move out during the build. You get clear stages, honest timescales and a finished home that works from top to bottom.
Homeowners across Barnet choose us for whole-house work because thirty-plus years of local experience shows in the planning. We understand how interwar houses are built, where the structure sits and how to phase trades so the job flows. One accountable team, transparent pricing and tidy working in an occupied home across N3, N12 and NW7.
I had a bathroom refit which I was very pleased with and I then went on to get my kitchen refitted as I was so happy with the way he worked. Even though I made a few changes to my original idea nothing bothered him and he worked his magic…

FAQ
The cost of home renovation tracks scope far more than postcode. We price the structural work, the finishing and the Barnet Council approvals as separate lines, so you can see where the money in a EN4 project in Barnet actually goes. As a rough guide, home renovation in London ranges from roughly £40,000 to £150,000 or more for a full refurbishment (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
You can usually stay in the house, depending which rooms are affected. We dust-seal the work area at EN4 and agree hours before home renovation begins at your Barnet property.
Quotes are free and carry no obligation. If the home renovation figure does not work for you there is no follow-up pressure, and the EN4 survey costs a Barnet homeowner nothing either way.
Most internal renovations in Barnet do not, though building regulations apply to structural, electrical and plumbing work. Extensions and external alterations may need permission or fall under permitted development. GS Renovation handles building control and any Barnet Council applications for your EN4 project.
We work on them week in, week out across Barnet and Enfield. The main thing home renovation demands at a EN4 address is proper investigation before anything structural is touched.
Yes. Across Barnet we regularly modernise interwar houses while protecting what makes them special. We restore cornicing, picture rails, panelled doors and original fireplaces where they survive, then rewire, replumb, replaster and reconfigure the layout around them. The result blends open-plan practicality at the rear with the period proportions and detail these Finchley and Mill Hill homes are known for.
