GS Renovation carries out structural alterations throughout Woolwich, working on the bay-fronted Victorian and Edwardian terraces with their rear closet wings and side returns, as well as the new riverside apartments in SE18. Over 30 years in the Royal Borough of Greenwich means we handle new openings, replacement joists, underpinning and supported openings correctly.
Structural alterations for Woolwich period homes
The Victorian and Edwardian terraces around Woolwich were rarely built for the way people live now, so structural alterations range from forming a wide opening into the rear closet wing to replacing tired or overspanned floor joists and creating supported openings between rooms. Each of these changes the loads in the building, so a structural engineer designs the work before anyone lifts a tool.
New openings in solid masonry are formed with a steel beam or lintel bearing onto padstones, propped temporarily and built in stages. Where old joists have sagged or been notched, we specify correctly sized replacements at the right centres. Where foundations are shallow, as they often are in older SE18 stock, underpinning may be designed to deepen and strengthen them safely.
Engineered and signed off across SE18
Every structural alteration in Woolwich is notifiable under the Building Regulations, so the Royal Borough of Greenwich building control department inspects the work and issues the completion certificate you will need when you sell. Planning permission is a separate matter that only bites on exterior changes in a conservation area or to a listed building, not on internal beams, joists or underpinning.
Because the flank and dividing walls of a Woolwich terrace are usually shared, forming openings, taking bearings or underpinning close to that boundary is notifiable under the Party Wall Act, and we serve the required notices on the neighbour. We coordinate the engineer, the party wall paperwork and the inspections so the alteration is properly designed, built and certified.
