The studio

We renovate homes the way we'd renovate our own — slowly, properly, only once.

Heartwood is a small, fully-employed crew of carpenters, joiners, plasterers and tilers led by two project leads. We don't subcontract anything load-bearing and we don't disappear after the snag list. Every project gets one point of contact, a fixed quote, and a weekly progress reel sent straight to your phone.

A.

In-house crew

No mystery subcontractors. The same team starts on day one and stays through handover.

B.

Fixed quotes

Itemised by trade and stage. If a wall hides a surprise, we tell you before we charge for it.

C.

10-year warranty

Structural work backed for a decade. Snag list closed within 14 days of handover.

What we build

From a single room to the whole envelope.

Six core renovation services, all delivered by the same crew. Pick one — or stack them into a full-house programme.

How we work

A four-step process. No surprises in week six.

  1. 01

    A 60-minute visit on site or video call. We measure up, listen to how you live, and leave with a rough budget band you can take to the bank.

  2. 02

    Design & quote

    Drawings, material boards, a stage-by-stage quote and a calendar. You sign off before any tools touch your house.

  3. 03

    Construction

    Single in-house crew, weekly reel sent to your phone, one project lead on Whatsapp. Site cleaned end of every Friday.

  4. 04

    Handover & warranty

    Walkthrough, snag list closed within 14 days, 10-year structural warranty issued. We check in at 6 and 12 months.

Word of mouth

Most of our work comes from clients telling friends.

“Heartwood ripped out a 1970s kitchen and gave us a room we actually want to spend time in. Came in £4k under budget. We've already asked them to quote the loft.”
Elena R.Belsize Park · Kitchen
“We've been through three builders on different jobs. This is the only one who actually finished the snag list before invoicing. Highest recommendation.”
Marcus W.Islington · Basement
“We got a weekly two-minute video of the site. I never had to chase anyone. The fixed quote held, the dates held, the work is gorgeous.”
Priya K.Richmond · Garden studio

Frequently asked

The questions we get on every first call.

How much does a full kitchen renovation cost in London?

Most of our kitchen renovations land between £55k and £160k depending on size, joinery, stone choice and whether structural work is involved. We'll give you a budget band on the first visit and a fixed quote after the survey.

How long does a typical project take from quote to keys?

Design and quote: 2–4 weeks. On-site work: 4–22 weeks depending on scope. A kitchen is usually 8–14 weeks; a basement 16–24 weeks. We give you a Gantt chart at quote stage.

Do you handle planning and Party Wall agreements?

Yes — both. We work with two architects we trust on planning applications and have an in-house Party Wall surveyor for adjoining-owner agreements. Both costs are listed separately on the quote.

Will we have to move out?

For a single-room renovation, usually no — we hoard off the working area and keep the rest of the house liveable. For full-house or basement projects we'll be honest at quote stage if it's not workable to stay.

What does the 10-year warranty cover?

All structural work (steels, openings, underpinning, roof structure) and water-tight elements (tanking, flat roofs, wet rooms). Wear-and-tear items like paint and door furniture carry a 24-month guarantee.
