Extensions & Loft Conversions in Chessington
In Chessington and across Kingston upon Thames we are most often asked for rear extensions on 1930s semis and hip-to-gable loft conversions. Conservation areas cover parts of Surbiton, Kingston's old town and Coombe, where private estate covenants may also apply. Inter-war houses usually have straightforward permitted development options, but a new vehicle crossover still needs council approval.

FAQ
Extensions & Lofts in Chessington
Not answered here? Call 07595 386864 and ask us directly.
Do you carry out extensions & loft conversions in Chessington?
Yes. Chessington is in Kingston upon Thames, where we work every week alongside Kingston, Surbiton, New Malden and Tolworth.
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.
