Extensions & Loft Conversions in Mill Hill
In Mill Hill and across Barnet we are most often asked for two-storey and wraparound extensions and loft conversions on inter-war semis. Hampstead Garden Suburb has some of the strictest controls in London, with a trust whose consent is needed in addition to the council's for most external changes. Elsewhere, Green Belt in the north and clay soil with mature trees are the main things to check before extending.

FAQ
Extensions & Lofts in Mill Hill
Not answered here? Call 07595 386864 and ask us directly.
Do you carry out extensions & loft conversions in Mill Hill?
Yes. Mill Hill is in Barnet, where we work every week alongside Finchley, Hendon, Golders Green and Edgware.
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.
