GS Renovation carries out structural alterations throughout Waltham Forest, from new openings in Leytonstone terraces to replacement joists and supported openings near Epping Forest. Drawing on more than 30 years in E4, E10, E11 and E17, we form new openings, renew failed timbers and underpin where the ground demands it, all engineered and signed off.
Structural alterations in Waltham Forest period homes
The borough's bay-fronted terraces come with their own quirks: rear closet wings, side returns and original softwood joists that have carried a century and a half of use. Common jobs in E11 and E17 include widening a doorway into a supported opening, forming a new opening through the rear wall for bifold doors, or replacing joists that have sagged or suffered rot in a damp closet wing.
Every alteration starts with our structural engineer working out what the existing structure carries and how the new arrangement will transfer that load. Openings are formed with a steel lintel or beam on padstones, propped temporarily while we cut through, and replacement joists are sized for the span and built into the wall on suitable bearings. Nothing is cut until the support above it is designed and ready.
Underpinning and building control in E4 and E10
Some Waltham Forest streets sit on clay that shrinks and swells with the seasons, and the mature trees around Lloyd Park and towards Epping Forest can worsen movement, so a small number of homes show settlement that calls for underpinning. Where an engineer confirms it, we underpin in carefully sequenced bays to deepen the foundation without undermining the wall, working to the design and to building control's inspections.
All of this work is governed by the Building Regulations rather than planning, so Waltham Forest Council's building control inspects and signs it off. Where an opening, a beam or underpinning affects the shared party wall with a neighbour, the Party Wall Act applies and we serve notice first. We keep the engineer, the notices and the inspections joined up so nothing falls between the trades.
