Builders in Richmond

GS Renovation works across Richmond upon Thames, covering TW1, TW2, TW9, TW10, TW11 and TW12 and the SW13 and SW14 postcodes at Barnes and Mortlake. This is the far side of London from our registered office in Potters Bar, and we are straightforward about that: Richmond projects are run as properly programmed jobs with the team on site for the duration, not as a series of short visits squeezed between other work.

The firm is run by Abdelaaziz Saaid, who has more than 30 years of hands-on experience on London properties. GS Renovation Ltd was incorporated in 2023 to formalise that trade. We are a building contractor with a structural specialism, which means we install the steel beams and take out the load-bearing walls ourselves rather than subcontracting the part of the job that carries the most risk. We are not structural engineers: on any structural work we appoint an independent engineer, build to their calculations and put the work in front of building control.

Richmond's housing and the work it calls for

Richmond has some of the best preserved period housing in London: Georgian and early Victorian townhouses on and around Richmond Green and the hill, Victorian and Edwardian terraces through Twickenham, Teddington and Kew, riverside houses along the Thames, and period cottages tucked behind the main roads. It is not all period, though. Of about 86,000 homes on the Valuation Office list, 38% were built before 1919, 24% between the wars and 37% after 1945, and 42% are flats, so the interwar semis of Whitton and Hampton and the post-war blocks sit alongside the townhouses. A great deal of the older stock is protected in one way or another, and that shapes what can be done and how.

The recurring jobs are period repair and sympathetic reconfiguration rather than wholesale change. Sash window repair and draught proofing rather than replacement. Lime plaster repaired in lime rather than patched in gypsum. Roof and parapet repairs on tall townhouses. Internally, the standard request is a side return or rear extension to widen a narrow Victorian kitchen, and opening the rear reception into it, which puts a steel beam into a period wall.

Proximity to the Thames adds a consideration that most of London does not have. Parts of the borough sit within Environment Agency flood zones, which affects basement and lower ground floor work, and it is worth establishing the flood risk position for a property before committing to below-ground plans.

• Full house refurbishments, rewiring, replumbing, heating, plastering and decoration
• Kitchen and bathroom installation, from strip out to final seal
• Steel beam (RSJ) installation and load-bearing wall removal
• Chimney breast removal with the stack above properly supported
• Rear, side return and double storey extensions
• Structural openings, new joists and supported alterations
• Building control notification, inspection and sign-off on all notifiable work

Richmond Council, conservation areas and listed buildings

Building control sits with Richmond Council, or with a registered building control approver if you choose one, and notifiable work must be notified, inspected and certified on completion. We make the application and book the inspections as part of the project.

Richmond upon Thames has a large number of conservation areas and listed buildings, and some streets also carry Article 4 directions, so check the council's Article 4 list for your address. In a conservation area a single storey rear extension can still be permitted development unless an Article 4 direction removes it, but side extensions, two storey rear extensions, roof enlargements and external cladding need planning permission. Listed building consent is separate from planning permission and covers internal work that affects the building's character, including removing walls and chimney breasts.

On terraced and semi-detached properties the Party Wall Act applies to beams cut into a shared wall, chimney breast removals and excavation near a neighbour's foundations. You serve the notice as building owner before work starts, and we give you the drawings and programme it needs.

Practicalities on Richmond projects

Much of central Richmond, Twickenham and Teddington is in a controlled parking zone, and the streets around the Green and the river are narrow with restricted access. Skip permits, suspended bays and delivery timing all need arranging in advance, and we programme them in.

Period properties reward a slower, better prepared start. Opening up a Georgian or Victorian house tends to reveal previous alterations that were never recorded, so we allow for investigation and recommend a larger contingency here than on a modern property. That is an honest expectation to set at the quotation, not a variation to spring later.
