B & F Pristine

All construction
work undertaken.

Extensions, loft conversions and whole-house refurbishment across west and north London. One team from the first drawing to the final clean, and a written price before anything starts.

Most building work goes wrong before anyone lifts a tool. It goes wrong in a vague quote, an assumption nobody priced, and a programme that was never written down.

We work the other way round. The survey is thorough, the specification is written, and the price is fixed and itemised trade by trade — so by the time the scaffold goes up, the only question left is the finish you want.

inside and out.

Loft conversions — dormer, hip-to-gable and mansard. The staircase is the decision that shapes the rest of the floor, so it gets settled first rather than last.

All construction work,
taken on whole.

Their van says all construction work undertaken, so this is what that covers. One team and one point of contact from the first drawing to the final clean; the number against each row is how many variants sit under it.

Rear, side-return and wrap-around. Party-wall notices, building control, structural steels, glazing, and the decoration that makes new work read as part of the old house rather than bolted onto it.

Priced before it starts,
on purpose.

A written price, itemised

Trade by trade, before a tool comes out of the van. An itemised quote is the only kind you can hold anybody to, and the only kind that turns a variation into an honest conversation rather than an argument.

One team, one number

The same firm from the first drawing to the final clean. Nobody waiting on anybody else, and no gap between trades for a problem to fall into.

The site left decent

Swept, secured and covered at the end of every day. It sounds like a small thing until you have lived through the alternative, and it is the part clients actually remember a year on.

Tell us what you are building,
in four taps.

No account and no form into the void — it assembles a WhatsApp message to the number on the van, and you press send.

(01) What are you building
(02) When, and roughly what budget

Budget

Both optional. Budget routes the conversation — “Not sure yet” is a fine answer. No figure on this page prices anything; the price comes from seeing the property.

(03) Where, and how to reach you
