GS Renovation carries out structural alterations throughout Tottenham, from new openings to replacement joists and underpinning in the Victorian and Edwardian terraces of N17. With over 30 years of building experience in Haringey, we design and install the supports your period home needs, all inspected and signed off under the Building Regulations.
Structural alterations across Tottenham homes
Tottenham's terraces were built with rear closet wings and side returns, and over time those additions and the original floors bring their own structural problems. We form new openings between rooms, replace tired or overloaded joists, create supported openings for wider doorways, and underpin foundations where movement or a basement dig calls for it. Each job starts with a structural engineer setting out the design.
Whatever the alteration, the principle is the same. A steel beam or lintel is sized for the loads it will carry, it bears onto padstones at each end, and the work above is temporarily propped while we cut and build. We demolish in staged sections, install the steel, then remove the props once everything is bearing correctly, so the house stays stable throughout.
Consents and sign-off in N17
Internal structural alterations in your N17 home are governed by the Building Regulations, not planning permission. Haringey Council's building control inspects the propping, the padstones and the finished steelwork. Planning only comes into play if you are in a conservation area and changing the exterior, or the property is listed, so most interior work simply needs building control approval and certification.
Where an alteration touches the shared party wall, such as bearing a beam into it or underpinning alongside it, the Party Wall Act applies and we serve notice on the adjoining owner first. We manage the engineer's calculations, the party wall notices and the building control inspections together, so a single team is answerable for every stage of the job.
