Structural Alterations in South Harrow.
Most of the houses in South Harrow were planned as a series of small rooms. Opening them up, whether that is knocking two reception rooms together, taking out the wall between the kitchen and dining room, or forming a wide opening onto the garden, is structural work, and it needs to be designed rather than improvised.
Our engineers design the steel beams, padstones and any temporary works, and our team installs them. The beam is usually hidden within the ceiling so the finished room shows no trace of the wall that was there. Building control inspects the work, and where the wall is shared with a neighbour we serve the party wall notices.
Structural alterations are often the first stage of a wider refurbishment, and we plan them as such, so the services, floor levels and finishes that follow are all designed together.

South Harrow: the houses and the planning rules.
South Harrow sits below Harrow on the Hill, with the Piccadilly line station at its centre and streets of 1930s semis and terraces running out towards Rayners Lane and Northolt. The older houses climb Roxeth Hill towards the school, and the plots on the flatter streets are generous.
We have built extensions and lofts in Rayners Lane and the surrounding roads for years. The pattern is a rear extension across the full width of the house, a hip-to-gable loft, and often a refurbishment of the kitchen and bathrooms in the same programme.
The Roxeth Hill conservation area covers the slope up to Harrow on the Hill; most other streets are unrestricted.
London Borough of Harrow
Harrow decides applications. Outside the Roxeth Hill conservation area, most single-storey extensions and lofts are permitted development.
Roxeth Hill
Within the conservation area, front alterations and roof changes visible from the street need a full application.
Party walls
Semi-detached and terraced houses share walls with neighbours; party wall notices are served before structural work.
Approvals for structural alterations in South Harrow.
Structural work needs building regulations approval and an engineer's calculations; where the wall is shared with a neighbour, party wall notices are required, and listed buildings need listed building consent for internal alterations.

Structural Alterations in South Harrow: your questions.
Can you remove a load-bearing wall in a South Harrow house?
Yes. Our structural engineer designs the steel beam and padstones, building control inspects the work, and if the wall is a party wall we serve the notices. The beam can usually be concealed within the ceiling depth.
Do structural alterations need planning permission?
Internal structural work does not need planning permission, but it always needs building regulations approval. Listed buildings need listed building consent for internal alterations.
