Extensions & Loft Conversions in Kensington and Chelsea
In Kensington and Chelsea we are most often asked for rear and lower ground floor extensions. Most of the borough lies within conservation areas and the council applies firm limits to basement excavations, including how they are built and managed. Check early on anything affecting the front of a property, the roofline or a party wall.

FAQ
Extensions & Lofts in Kensington and Chelsea
Not answered here? Call 07595 386864 and ask us directly.
Do you carry out extensions & loft conversions in Kensington and Chelsea?
Yes. We work across Kensington and Chelsea, including Chelsea, South Kensington, Earl's Court, Notting Hill and Holland Park.
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.
