Structural Alterations Kingston upon Thames

GS Renovation carries out structural alterations throughout Kingston upon Thames, from new openings in Surbiton's Victorian terraces to replacement joists and underpinning on older riverside houses near the Thames. Across KT1, KT2, KT3, KT5 and KT6, our 30-plus years of experience means new steel, supported openings and foundations are designed, installed and signed off properly.

Structural alterations for Kingston's period houses

Structural alterations cover far more than knocking a wall through. In Kingston's Victorian and Edwardian terraces we form new door and window openings in solid brickwork, replace tired or overloaded floor joists in the closet wings, install supported openings between rooms, and underpin where old shallow foundations have moved. Each of these begins with a structural engineer setting out the design, the loads and the exact steel or support required.

The riverside setting near the Thames and Bushy Park means some of the borough's older homes sit on ground that has taken on moisture over the decades, and settlement cracking is not unusual. We investigate the cause before proposing a fix, so underpinning is only used where it is genuinely needed. Where the answer is a new beam instead, it is sized by the engineer, seated on padstones and propped safely during installation.

Getting Kingston alterations signed off correctly

Any alteration that changes how your Kingston home carries load is notifiable under the Building Regulations, so Kingston Council's building control inspects the work and certifies it. That applies to new openings, replacement joists, supported openings and underpinning alike. We arrange the inspections at the right stages, supply the engineer's calculations, and make sure padstones, beams and foundations are checked before they are covered up.

Where an alteration touches the party wall shared with a neighbouring terrace, whether cutting a beam bearing into it or excavating close to it for underpinning, the Party Wall Act is triggered and notice must be served. On tightly packed KT streets this is common, so we coordinate the work around the party wall award as part of the job. Only listed buildings or exterior changes in a conservation area bring planning consent into the picture.
