GS Renovation carries out structural alterations throughout Southall, from new openings and replacement joists to supported openings and underpinning in the interwar houses of UB1. Over 30 years working across Ealing, Hanwell and Acton means we understand how these 1930s properties are built and how to change them without compromising the structure.
Structural alterations for Southall homes
Interwar houses in Southall sit on generous plots, so alterations here are varied: widening a doorway between reception rooms, forming a new opening to a side return, replacing tired floor joists, or installing a supported opening where a beam carries the wall above. Each of these changes how load travels through the building, so we begin with a structural engineer's design rather than guesswork on site.
For openings we use steel beams bearing onto padstones, temporary propping and staged demolition, exactly as the calculations require. Where original 1930s joists have sagged or been weakened by earlier alterations, we replace them to modern spans. Every element is designed to carry its share of the load so your interwar home stays sound long after the work is finished.
Underpinning and consents in Southall
Some UB1 homes show movement in the older shallow foundations typical of the interwar period, particularly on the clay soils common across West London near Walpole Park and Ealing Common. Where an engineer confirms it is needed, we underpin in controlled sequenced bays to deepen the foundation safely, and we always establish the cause first so the fix addresses the real problem rather than the symptom.
Structural alterations are governed by the Building Regulations, so they need building control sign-off, not planning permission, unless you are altering the exterior in a conservation area or a listed building. Where an alteration affects the shared party wall of your semi, we serve notice on the neighbour under the Party Wall Act, then manage Ealing Council's building control inspections through to the completion certificate.
