GS Renovation carries out structural alterations throughout Southgate's interwar streets, from new openings in the spine wall to replacement joists and underpinning beneath 1930s semis on their generous N14 plots. With more than 30 years of experience across Enfield, we design, prop and sign off every supported opening to the Building Regulations.
Structural alterations for Southgate's interwar homes
The 1930s and interwar houses around Southgate were solidly built, but their layouts and their timbers reflect the standards of ninety years ago. We form new supported openings between rooms, replace joists that have sagged or suffered decay, and install steel where a wider span is needed, always to a structural engineer's specification rather than guesswork on site.
Where a house near Southgate has movement in a corner or a bay, underpinning may be the answer. We work to the engineer's design, excavating and pouring in sequence so the foundation is deepened without undermining the wall above. Every supported opening bears onto padstones, is propped while the steel goes in, and is inspected before it is closed up.
Engineer and building control across N14
Structural alterations in an N14 home are notifiable under the Building Regulations. Enfield Council's building control, or an approved inspector, reviews the calculations, inspects propping, beam bearings and any underpinning before they are covered, and issues the completion certificate. This is separate from planning permission, which internal structural work in Southgate does not require unless the house is listed.
Because Southgate's semis share a party wall with the house next door, alterations that cut into or bear onto that wall, or that involve underpinning close to it, are notifiable under the Party Wall Act. We identify this at survey stage and serve the correct notices on your neighbour, so the work proceeds properly and the relationship along the street stays a good one.
