Structural alterations are everyday work for GS Renovation in Tooting. Across SW17's bay-fronted Victorian and Edwardian terraces we form new openings, replace tired joists, underpin failing foundations and install supported openings between rooms. Drawing on more than 30 years of building experience, we treat every alteration as an engineered job, designed on paper before a single brick is disturbed.
Structural alterations in Tooting's period homes
The rear closet wings and side returns typical of Tooting terraces are where most alterations happen: a new opening into the side return, a wider doorway between kitchen and dining space, or a beam to carry a first floor after ground-floor walls come out. Each one starts with a structural engineer sizing the steel, specifying padstones and confirming the bearings can carry the load.
Where original floor joists have sagged or been notched for old pipework, we replace them to modern spans. Where foundations have moved on Tooting's clay-influenced ground, underpinning deepens and strengthens them in careful sequenced bays. Whatever the alteration, we prop temporarily, work in stages and keep the rest of your Victorian terrace fully supported while the change is made.
Regulations and party walls in SW17
Internal structural alterations are controlled under the Building Regulations rather than planning permission. Wandsworth Council's building control inspects new beams, joists and underpinning and certifies the finished work. The exception is exterior change in a conservation area or to a listed building, which needs separate consent; we tell you at the outset which rules apply to your particular SW17 property.
Because these terraces share a party wall with the neighbours, alterations that cut into or bear onto that wall, or that involve underpinning near the boundary, are notifiable under the Party Wall Act. You serve the correct notices, coordinate with your neighbour and keep the paperwork straight, so your alteration is both structurally sound and fully compliant from start to finish.
