GS Renovation carries out structural alterations across Morden, tailoring each job to the borough's 1930s and interwar housing. Whether you own a semi-detached house near Mitcham Common or an interwar home close to Morden Hall Park, our 30+ years in SM4 covers new openings, replacement joists, supported openings and underpinning, all engineer-designed and signed off.
Structural alterations for Morden's interwar homes
Morden's suburban houses were built with shallow strip footings and solid brick walls, which is why any change to the structure begins with a proper engineer's assessment rather than assumptions. We form new openings for wider doorways and bi-folds, insert supported openings where a wall is only partly removed, and replace tired or overspanned floor joists that were never designed for today's loft conversions and heavier bathrooms.
Where these interwar footings have moved on Morden's clay-influenced ground, underpinning stabilises the foundations before any further work. Every steel is sized by a structural engineer, bears onto padstones and is installed with temporary propping and staged demolition. On the generous SM4 plots there is usually space to bring materials in and stage the work without turning the whole house upside down.
Consents and building control in Morden
It is worth being clear about consents. Internal structural alterations in Morden are governed by the Building Regulations, not planning permission, so you generally will not need a planning application to move a wall or upgrade joists inside a standard SM4 house. Planning or listed-building consent only comes into play for exterior changes in a conservation area or on a listed building, which we will flag if it applies to your property.
Because most Morden houses are semi-detached, alterations that touch or bear onto the shared party wall are notifiable under the Party Wall Act, and we serve notice on the neighbour first. Merton Council's building control then inspects the structural work at the key stages and issues the completion certificate. We coordinate the engineer, the notices and the inspections so nothing is left hanging.
