Extensions & Loft Conversions in Dollis Hill
In Dollis Hill and across Brent we are most often asked for rear extensions and loft conversions. Queen's Park, parts of Kilburn and several inter-war estates are conservation areas, some with extra controls on front gardens and windows. Paving over a front garden for parking needs a dropped kerb application and a surface that drains properly.

FAQ
Extensions & Lofts in Dollis Hill
Not answered here? Call 07595 386864 and ask us directly.
Do you carry out extensions & loft conversions in Dollis Hill?
Yes. Dollis Hill is in Brent, where we work every week alongside Wembley, Stonebridge, Willesden and Kilburn.
Do I need planning permission for an extension?
Not always. Many single-storey rear extensions and loft conversions fall under permitted development, which has size limits and does not apply to flats, maisonettes or some conservation areas. We check your property at the site visit and tell you which route applies before you spend anything on drawings.
How long does an extension take?
A typical single-storey rear extension takes around 10 to 14 weeks on site once approvals are in place. A loft conversion is usually 8 to 12 weeks. We give you a written programme with the quote so you know what happens each week.
Can we live in the house during the work?
Usually yes. We seal off the working area, keep a kitchen and bathroom running wherever possible, and agree the noisy or dusty days with you in advance.
