Extensions & Loft Conversions in Richmond upon Thames
In Richmond upon Thames we are most often asked for kitchen extensions on Edwardian houses and loft conversions in Teddington and Twickenham. The borough has a very high number of conservation areas and protected trees, so check before altering frontages or working near mature trees. Homes close to the Thames may need flood risk to be addressed for extensions and any lower ground floor work.

FAQ
Extensions & Lofts in Richmond upon Thames
Not answered here? Call 07595 386864 and ask us directly.
Do you carry out extensions & loft conversions in Richmond upon Thames?
Yes. We work across Richmond upon Thames, including Richmond, Twickenham, Teddington, Kew and Barnes.
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.
