Single and double storey extensions in Paddington. Trusted, professional, 30+ years' hands-on experience.
Extending a period home in Paddington calls for a builder who understands Westminster's planning rules and the age of the fabric. GS Renovation has spent more than 30 years working on Georgian and Regency townhouses across W2, delivering rear, side-return and wrap-around extensions with the foundations, steelwork and fit-out handled by a single team.

Whether a Paddington extension is permitted development or needs a full planning application depends heavily on the property. Many W2 houses sit within a conservation area, and a large number are listed, which removes or restricts permitted development rights and can require listed building consent. We help you establish where your home stands with Westminster City Council before design work commits you to a particular route.
For a rear or side-return extension on an unlisted terrace, permitted development may cover the work, but tight urban plots, boundary distances and the impact on neighbouring townhouses all need checking. Where a full application is required, we prepare for the drawings and the council's assessment. Getting the planning position right at the outset avoids enforcement problems later and keeps a period home's value intact.
Once the route is agreed, the build follows a familiar sequence on Paddington's solid-walled homes. We form new foundations by hand where access is tight, tie the new structure into old masonry, and install steel beams sized by an engineer to carry the opening between the house and the extension. Every beam bears onto proper padstones and is signed off by building control before the works are closed up.
Rear closet wings and side returns are common on W2 terraces, and infilling them creates the bright kitchen-diner many owners want without losing the garden. We manage party wall notices where the works affect a shared boundary, coordinate roofing, glazing and services, then complete the full internal fit-out. The finished extension respects the proportions and detailing of the original period house.
Homeowners across Paddington choose GS Renovation because extending a listed or conservation-area property is not a job for a general builder. We understand Westminster's rules, the Party Wall Act and the way period fabric behaves, and we carry the project from foundations to final decoration. Over 30 years in W2 means fewer surprises and a build that lasts.
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!

Many single-storey rear extensions in Paddington fall under permitted development, but side returns, double-storey extensions and work in conservation areas usually need full planning permission. We assess your property and manage both the planning application and building control.
Yes. A large share of Paddington's homes are period, Georgian and listed properties, and we renovate them regularly. We plan each house extensions around their particular characteristics, such as conservation and listed-building rules, solid walls and original period features, so the result suits the building and meets building control.
It depends on the property. Structural work always needs building regulations approval, but many Paddington homes are listed or in a Westminster conservation area, so an extension may also need planning permission or listed building consent rather than falling under permitted development. We check your home's status with the council first, then design to whichever route applies.
