From new door openings to replacement joists and underpinning, GS Renovation carries out structural alterations throughout Hayes. Working across UB3's 1930s and interwar housing stock for more than 30 years, we handle the engineering, the supported openings and the Hillingdon building control sign-off on homes built between the wars.
Supported openings in Hayes suburban homes
The generous plots that came with Hayes interwar houses mean owners often want wider openings between rooms, a new opening into a side return, or a garage converted into living space. Each of these cuts into masonry that is doing a structural job, so we form supported openings using a steel lintel or beam that carries the load above onto solid bearings at each side.
Older interwar properties in UB3 sometimes need more than a new opening. Where floor joists have sagged or been notched over the decades we fit replacement joists, and where original foundations are shallow we underpin to give the structure a sound footing. A structural engineer specifies every element, and we prop, cut and rebuild in a controlled sequence so the house is never left unsupported.
Engineering and consents in UB3
Structural alterations in Hayes are notifiable under the Building Regulations, and Hillingdon Council's building control inspects the steelwork, bearings, joists or underpinning before signing them off. This is separate from planning permission, which internal structural work does not require unless the property is listed or in a conservation area. We manage the notices and inspections so the paperwork is complete and certified.
Because Hayes is largely semi-detached, alterations near the boundary frequently involve the party wall shared with the attached neighbour. Cutting into or building off that wall makes the work notifiable under the Party Wall Act, so you serve notice before starting. One team looks after the engineer's design, the party wall process, the build itself and the final certificate, keeping the whole alteration accountable to you.
