GS Renovation carries out structural alterations throughout Pimlico, from forming new openings in the garden-square terraces to replacing tired joists and underpinning below SW1's Georgian and Regency townhouses. More than 30 years working on Westminster's period stock means we understand how these listed and conservation-area homes are built and how to change them without harming them.
Structural alterations for Pimlico's period homes
Alterations in Pimlico cover far more than knocking a wall through. We form new supported openings between rooms, replace joists that have sagged or been weakened over a century and a half, install steel to carry masonry above a widened doorway, and underpin where the original shallow Georgian footings need strengthening for a basement or a heavier load.
Every one of these is an engineered job. A structural engineer specifies the beam sizes, the padstones they bear onto, the joist spans and any underpinning sequence, and we build strictly to those calculations. In a tall Regency townhouse the loads stack up through several storeys, so getting the support detail right at each level matters as much as the finished appearance.
Consents and controls in Westminster's SW1
Where an alteration touches the party wall shared with the house next door, whether cutting in a new bearing or underpinning along the boundary, the Party Wall Act applies and we serve notice on the adjoining owner in good time. Pimlico's tight-packed terraces mean this comes up on most jobs, so we treat it as a standard early step rather than an afterthought.
The structural work itself is notifiable under the Building Regulations and Westminster City Council's building control inspects and signs it off. Internal alterations do not need planning permission. That changes only if the property is listed or the work affects a conservation-area exterior, in which case listed-building or planning consent is required, and we help you establish which applies before committing.
