GS Renovation carries out structural alterations throughout Hillingdon, from new openings and replacement joists to supported openings and underpinning. Working across UB3, UB7 and HA6, we bring over 30 years of experience to the borough's 1930s semi-detached and interwar houses, delivering engineer-designed, building-control-certified work in Uxbridge, Hayes and Ruislip.
Structural work for Hillingdon's suburban houses
Interwar houses on Hillingdon's generous plots lend themselves to all sorts of structural change: a wider opening between kitchen and dining room, a new door punched through a solid wall, replacement joists where an old floor has sagged, or a supported opening for bifold doors onto the rear garden. Each one alters how loads travel through the building, so each one needs a structural engineer to design the support before any brick is cut.
Where the ground has moved and a corner has settled, underpinning may be needed to take the foundation down to firmer bearing. On the sandy and clay soils found across parts of the borough near the Grand Union Canal, seasonal movement is not unusual. We excavate and pour underpinning in short controlled bays to engineer's detail, never undermining more than a small section of wall at once, keeping the house stable throughout.
Getting alterations signed off in Hillingdon
Structural alterations inside your home fall under the Building Regulations, and Hillingdon Council's building control department, or an approved inspector, inspects and certifies the work. This is separate from planning permission, which internal structural changes do not require. Only if your home sits in a conservation area or is listed, and you are altering the exterior, would planning consent enter the picture. We tell you clearly which route applies before we begin.
New openings and beams that bear into the party wall shared with a neighbouring semi bring the Party Wall Act into play, so notice is served next door before work starts. We coordinate the engineer's design, the padstones and bearings, temporary propping, staged demolition and every building control inspection, then hand you the completion certificate. One team is accountable from the first calculation to the final sign-off.
