Structural Alterations New Cross

GS Renovation carries out structural alterations throughout New Cross and neighbouring Deptford, Lewisham and Forest Hill. Across SE14's Victorian and Edwardian terraces we form new openings, replace tired joists, install supported openings and underpin where the ground has moved, all engineer-designed and signed off. Over 30 years of building experience stands behind every calculation.

Structural alterations across New Cross homes

The terraced stock around New Cross throws up a predictable set of structural jobs. Rear closet wings and side returns invite new openings into the kitchen; original softwood joists in the reception floors sometimes need replacing after decades of notching for pipes and cables; and wider openings between rooms call for a supported beam rather than a simple lintel. We match the solution to what the house is actually doing, not to a standard template.

Every alteration begins with a structural engineer who calculates the loads and specifies the steel. Beams are sized for the span, seated on padstones and propped while we work. Where an original bay or a bearing wall has settled, underpinning stabilises the foundation before we build on it. The principle is constant across SE14: understand the load path first, then support it permanently before removing anything.

Consents and controls in Lewisham

Internal structural alterations are governed by the Building Regulations, so Lewisham Council's building control or an approved inspector reviews the design, inspects the steelwork and bearings, and certifies the finished job. This is not a planning matter. Planning permission only becomes relevant for external changes within a conservation area, so most alterations inside a New Cross terrace proceed on a building regulations basis alone.

Because these terraces share party walls and chimney stacks with the houses either side, alterations that cut into or bear onto that shared wall are notifiable under the Party Wall Act. You serve the correct notices on your neighbours before starting. From the engineer's drawings through underpinning, new joists and supported openings to the final certificate, one team keeps the whole process moving and documented.
