Full refurbishments and whole-house renovations in Finchley. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes whole homes across Finchley, where solid 1930s semis and interwar houses in N3 often keep their original layouts and dated services. With over 30 years of experience across Barnet, we take on the full project, sequencing structural work, rewiring, plumbing, plastering and finishing so one team carries the house from tired to transformed.

Many Finchley houses come to us with wiring, pipework and boilers that have not been touched in decades, alongside compartmentalised rooms that no longer suit family life. We plan the whole job in the right order, rewiring and replumbing first while walls are open, then reconfiguring the layout, replastering throughout and fitting new kitchens and bathrooms before decoration. Managing it as one project avoids the gaps and clashes that come from stringing together separate trades.
Reconfiguring a 1930s semi often means removing a load-bearing wall to open the ground floor, which we tie into the wider refurbishment so the steel, the new services and the finishes all land together. On the larger interwar homes we can restage the flow between the kitchen, dining and living areas while upgrading insulation and heating, giving a solid old house modern performance without losing its character.
Finchley's 1930s and interwar houses were built with features worth keeping, from bay windows and picture rails to original doors, fireplaces and stained glass. Where these survive we restore and reinstate them, blending the repaired detail with the new plaster and joinery so the house feels considered rather than stripped bare. Where features are long gone, we can recreate sympathetic mouldings and skirtings that suit the age of the property.
The plots around Finchley and towards Golders Green and Hendon give scope for bigger refurbishments that combine a rear extension with a full internal overhaul. We handle building control for any structural or notifiable work, keep the site tidy in an occupied home where possible, and hand back a house that is rewired, replumbed, replastered and finished to a consistent standard throughout.
Finchley homeowners choose GS Renovation because a full refurbishment needs one team holding the whole sequence together, not a string of separate contractors. We handle the rewire, the replumb, the structural changes, the plastering and the finish under a single point of contact, with clear pricing and 30+ years of experience refurbishing Barnet's interwar homes.
