From new openings to replacement joists and underpinning, GS Renovation carries out structural alterations across Harlesden's NW10 streets. The area's bay-fronted Victorian and Edwardian terraces, with their rear closet wings and side returns, throw up all sorts of structural challenges, and our 30-plus years in Brent means we have seen and solved most of them.
Structural alterations for Harlesden terraces
Alterations in a Harlesden terrace rarely mean a single simple change. Widening the opening into a rear closet wing, forming a supported opening for a side-return kitchen, or replacing tired timber joists over a damp-affected room all need a structural engineer to design the beam sizes, bearings and padstones before any brick is cut. We start with that survey so the solution matches the actual loads.
Where original footings have settled, common in period NW10 housing on London clay, we underpin in carefully sequenced bays to deepen the foundations without undermining the wall. Every supported opening gets temporary propping, a properly sized steel bearing onto padstones, and staged demolition, so the structure above is never left carrying more than it should at any point.
Building control and party walls across Brent
Internal structural alterations are governed by the Building Regulations, so Brent Council building control inspects and certifies the work; you do not need planning permission for the structure itself. Planning only comes into play for external changes in a conservation area or to a listed building, and we will flag clearly if your particular project touches that side of things.
Underpinning, new openings and joist work in these terraces frequently involve the shared party wall you have in common with the house next door, which makes them notifiable under the Party Wall Act. We prepare and serve the notices on the adjoining owner, coordinate access where needed, and keep neighbours informed so the alterations proceed smoothly on a tightly packed Harlesden street.
