GS Renovation carries out structural alterations throughout Edgware's 1930s and interwar housing, from new openings and replacement joists to supported openings and underpinning. Backed by more than 30 years working across HA8, Barnet and neighbouring Hendon, Finchley and Golders Green, we design each alteration around what your suburban semi is actually built from and holding up.
Structural alterations for Edgware's interwar homes
Interwar Edgware houses were built with solid brick spine walls, timber floor joists and generous rear elevations, which gives plenty of scope for change but demands proper design. Whether you want a new opening from kitchen to garden, a wider doorway between reception rooms, or replacement joists where an old floor sags, we start with a structural engineer's calculations so the new steelwork or timber is correctly sized for the loads above.
Every new opening in these homes gets a steel lintel or beam bearing onto padstones, with temporary propping while we work and a safe staged sequence for taking out the old masonry. Where a rear addition or bay has settled on shallow interwar foundations, underpinning may be specified to stabilise it. We build strictly to the engineer's drawings and the Building Regulations at each step.
Coordinating engineer and building control in Edgware
Structural alterations are notifiable under building regulations rather than planning, so internal reconfiguration of an HA8 semi does not need a planning application unless your property sits within a conservation area or is listed, in which case exterior work needs consent. We tell you clearly which route applies to your home before we start and manage the building control submission with Barnet Council or an approved inspector.
Because Edgware semis share a party wall with the house next door, alterations that cut into or load that shared wall, including new beams and underpinning near the boundary, fall under the Party Wall Act and require notice to be served on the neighbour. You serve those notices, arrange the engineer's inspections, and see the work through to a building control completion certificate.
