Structural Alterations in Harrow.
Most of the houses in 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.

Harrow: the houses and the planning rules.
Harrow is Metroland: the streets around Harrow-on-the-Hill, North Harrow and Rayners Lane were built between the wars for commuters on the Metropolitan line, with generous semi-detached houses on plots that suit rear extensions and loft conversions. On the Hill itself, the village around the school is older, with Victorian and Georgian houses inside a conservation area.
It is one of our busiest areas. We have built a rear extension with bi-fold doors and a new kitchen in Rayners Lane, a loft and six-metre rear extension in Harrow on the Hill, refurbished a house in North Harrow, and fitted out cafés in St George's shopping centre and at the bus station.
The Harrow on the Hill Village and Roxeth Hill conservation areas cover the Hill; most of the borough is unrestricted.
London Borough of Harrow
Harrow decides applications. Outside the Hill's conservation areas, most rear extensions and loft conversions fall within permitted development, subject to the usual size limits.
Permitted development
Single-storey rear extensions up to 3 metres, or 6 metres with prior approval, and rear dormers within 50 cubic metres are typical. A lawful development certificate is worth obtaining for resale.
Harrow on the Hill
Within the village conservation area, extensions and roof changes need a planning application and matching materials.
Approvals for structural alterations in 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 Harrow: your questions.
Can you remove a load-bearing wall in a 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.
