GS Renovation carries out structural alterations throughout Notting Hill, from Regency townhouses near Holland Park to the stucco-fronted terraces around Portobello Road. Drawing on more than 30 years in W11, we form new openings, replace tired joists, underpin failing foundations and create supported openings in the period homes of the Royal Borough of Kensington and Chelsea.
Structural alterations for Notting Hill's period homes
The Georgian and Regency stock of Notting Hill was built to standards of its day, so alterations here mean working with lime-based masonry, deep basements and timber floors that have carried load for well over a century. Whether you are cutting a new opening between reception rooms, widening a doorway or replacing rotten joists beneath a bay, every alteration starts with a structural engineer establishing what the existing structure is holding.
New openings are formed with steel beams or lintels sized to the load, bearing onto padstones and installed behind temporary props. Replacement joists are matched to span and spacing, and where a W11 basement or lower-ground floor shows settlement we underpin in short, engineered bays so the foundation is deepened safely rather than undermining the wall above.
Consents and sign-off across W11
Because Notting Hill terraces share party walls, structural alterations that cut into, bear onto or underpin a shared wall are notifiable under the Party Wall Act. You serve notice on the adjoining owner and agree the working details, which matters in W11 where neighbouring homes are often equally historic and equally valued.
Underpinning, beams and supported openings are all controlled under the Building Regulations, and the Royal Borough of Kensington and Chelsea's building control inspects the works at the key stages. Internal alterations do not need planning permission, but if your home is listed or within a conservation area we check whether listed building consent is required before we start, so the right permissions are in place from day one.
