Full refurbishments and whole-house renovations in Marylebone. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes whole flats and houses across Marylebone, giving the elegant mansion blocks and Georgian townhouses of W1 the services and layout that modern life needs. With over 30 years in Westminster, one team manages the structural work, rewiring, replumbing and finishes so a full renovation runs as a single, coordinated project.

The period flats behind Marylebone's red-brick facades often still carry decades-old wiring, tired pipework and layouts that split the space into small, dark rooms. We strip back and renew properly, rewiring to current standards, replumbing, replastering and reconfiguring the plan so hallways, reception rooms and bedrooms work for how the flat is actually lived in today.
Sequencing is everything in an occupied block. We run the first-fix electrics and plumbing, any steel and structural changes, then plastering, joinery, kitchens, bathrooms and decoration in the right order, so trades are not tripping over each other. Throughout, we work within the building's noise hours and the freeholder's conditions, protecting communal stairs and lifts as we go.
Marylebone's Georgian and Edwardian interiors carry cornicing, ceiling roses, panelled doors, sash windows and fireplaces that give the rooms their character. Where these survive we repair and restore them, and where they have been lost to earlier modernisation we can reinstate sympathetic profiles, balancing the period feel of the building against the insulation, sound reduction and heating a comfortable W1 home now expects.
A whole-house renovation is also the moment to improve comfort quietly. Between flats we can upgrade acoustic separation to reduce noise transfer, a common concern in purpose-built blocks, and we route new services thoughtfully so they disappear into the fabric. Notifiable electrical work is certified under building regulations, and we hand over the paperwork your freeholder and future buyer will want.
A Marylebone refurbishment involves many trades, a leaseholder's obligations and a live building around you. GS Renovation gives you one accountable team for the whole job, from first-fix services to the final coat, working within Westminster's building rules and the block's management. Our 30+ years mean tidy working, sensible sequencing and a finish that respects the period property.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
FAQ
Every Marylebone project is priced on its own merits, as the cost of home renovation varies with the size, specification and condition of the home. We give a clear, itemised quote up front with no obligation. Call 07472 424 226 for an estimate tailored to your property. 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.
Most home renovation projects in Marylebone take between two and eight weeks depending on the scope and whether structural work is involved. We provide a clear programme before work begins so you know exactly what to expect.
Because we manage every trade in-house, your Marylebone project stays consistent and accountable from first fix to finish. Add transparent pricing, full insurance and real aftercare, and it is easy to see why Marylebone clients recommend us.
Most internal home renovations in Marylebone do not need planning permission, though building regulations apply to structural, electrical and plumbing work. Extensions or external changes may need permission or fall under permitted development. We handle building control and any applications for you.
Yes. A large share of Marylebone's homes are mansion-block and period-flat properties, and we renovate them regularly. We plan each home renovation around their particular characteristics, such as leasehold consents, shared structure and sound insulation between flats, so the result suits the building and meets building control.
Internal renovation does not need planning permission, but your lease almost certainly requires the freeholder's consent, and structural or notifiable electrical work must meet building regulations. We help you obtain the licence to alter, coordinate with the managing agent, and certify the regulated work, so the refurbishment is fully compliant with both your lease and the law.
We cover the whole of Marylebone and the W1 area and the surrounding Central London. If you are nearby and not sure, just call 07472 424 226 and we will tell you straight away.
