Design & Build in Harrow.
Design and build means we take responsibility for the whole project, from the first sketch to the day you move back in. There is one contract, one programme and one person to call, and the people who drew the scheme are in the same office as the people building it.
For a house or flat in Harrow that covers the measured survey, concept and developed design, planning and building regulation drawings, the applications themselves, construction by our own site team, the kitchen and bathrooms we supply, joinery, decoration and handover with a guarantee on the work.
The advantage is simple: nothing falls between an architect, a planning consultant and a builder, because they are the same team. Problems are solved on the drawing board rather than on site, and the price and programme are set before work starts.

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 design and build in Harrow.
All approvals are managed within the contract, so design, consent and construction run as one programme with one team responsible for each.
