Delivering in Kensington

Kensington houses are technically demanding. Grade II listing, listed party walls, basement engineering under a stucco facade and a Royal Borough of Kensington & Chelsea planning department that expects proper drawings and proper trades. We work here every week. Our teams know the streets, the neighbours' surveyors and the site logistics you need to run a full refurbishment on a Cornwall Gardens crescent without upsetting the entire postcode.

Ushii is a London construction house working with private clients, family offices and developers across Kensington and the surrounding prime postcodes. Every project is delivered by our own directly employed teams under a single point of accountability from first survey to final handover.

Answers

What Kensington clients ask.

Detailing for Kensington houses

Do you work under RBKC planning conditions?

Every week. We handle basement impact assessments, party wall awards, conservation area consents and the noise and hours conditions RBKC applies to prime streets.

What's a realistic programme for a whole-house Kensington refurbishment?

For a five-storey townhouse without a new basement, plan on nine to fourteen months from strip-out to snag list. Add three to six months if you're excavating underneath.

Do you have Kensington references?

Yes. We share addresses and introduce previous principals privately after an initial call. Discretion is the point of the service.
