Structural Alterations in Pinner.
Most of the houses in Pinner 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.

Pinner: the houses and the planning rules.
Pinner is Metroland with a medieval village at its centre: a High Street of timber-framed and Georgian buildings running up to the church, surrounded by streets of well-built 1930s houses and, on the hill, larger detached homes on generous plots. The Metropolitan line makes it one of the most sought-after suburbs in north-west London.
Most of the work is to the inter-war houses: rear and side extensions that turn a small kitchen into a family room, hip-to-gable and rear dormer lofts, and full refurbishments that modernise services and layouts while keeping the bay windows and brickwork that give the streets their character.
The Pinner High Street and Pinnerwood Park conservation areas cover the village and its garden estate; most other streets are unrestricted.
London Borough of Harrow
Harrow decides applications. Outside the two conservation areas, most rear extensions and lofts fall within permitted development, confirmed by a lawful development certificate.
Pinner village
Within the High Street conservation area and around listed buildings, external changes need a full application and careful materials.
Larger extensions
Double-storey and wraparound extensions need a householder application and are assessed on their effect on neighbours and the street.
Approvals for structural alterations in Pinner.
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 Pinner: your questions.
Can you remove a load-bearing wall in a Pinner 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.
