What is the cost range for a Hampstead whole-home refurbishment?

Hampstead whole-home refurbishments typically run £500,000–£1,800,000+ depending on floor area, whether it includes a loft or basement extension, and the interior specification. We provide a fixed-price contract before you commit, with all inclusions/exclusions defined.

How discreet is your on-site presence?

Very. Our Hampstead teams are briefed on site conduct — professional, quiet, no oversized branding or noise, tidy welfare units, and secured deliveries. Neighbour communication is handled by the project lead, not the site team.

Do you deliver bespoke new builds in Hampstead?

Yes. We've delivered bespoke new builds within existing façades and on infill plots in NW3. See our recent Hampstead new-build case study for scope, sequencing and finish detail.

Can you work with our interior designer and architect?

Absolutely. Many of our Hampstead projects run alongside an appointed interior designer and architect. We integrate their specifications into our procurement and programme, and we build directly against the drawings — not a value-engineered version of them.

Hampstead residential street — Prime Build Design

Ultra-Premium Bespoke Craftsmanship · NW3

Builders in
Hampstead.

Hampstead is one of London's most demanding and rewarding places to build. Its Georgian townhouses around Well Walk and Church Row, the Victorian mansions on Christchurch Hill, and the streets that step down from the Heath into the Village — many inside the Hampstead Conservation Area — represent some of the finest domestic architecture in the country. Homeowners here expect construction to match. Prime Build Design's Hampstead practice is our ultra-premium tier: bespoke joinery, stone and marble finishes, discreet site management, and a build standard that earns its referrals.

NW3: London's ultra-premium residential district

Hampstead's housing stock is unusually varied: Georgian and early-Victorian townhouses of exceptional pedigree; late-Victorian and Edwardian mansions with substantial gardens and often original service wings; and the smaller cottages around Flask Walk and Well Walk that read as some of the most desirable small homes in London. Camden Council's planning approach in NW3 is careful and detailed, particularly inside the Hampstead Conservation Area, and clients here expect the entire building process — from initial survey through party-wall and planning through to final snagging — to be handled to a standard that matches the value of the home. We work here often, and every project we deliver in NW3 is led by a senior project manager and specified against the highest interior finish tiers.

Hampstead landmarks and neighbourhoods we work in

We're regularly on-site in Hampstead Village (NW3), the streets around Well Walk, Flask Walk, Downshire Hill and Church Row, in South End Green and up towards the Heath around East Heath Road and Christchurch Hill. Many of our Hampstead projects sit inside the Hampstead Conservation Area, and we understand what Camden expects: careful drawings, material samples matched to the street, retained sash windows and joinery detail, and roof-line changes that respect neighbouring homes. Where the project sits within a listed home, we coordinate Listed Building Consent alongside your heritage consultant.

Services we deliver in Hampstead

The bulk of our Hampstead work is at the ultra-premium end: bespoke new builds behind existing façades; whole-home refurbishments across four or five floors of a Georgian townhouse; discreet loft and mansard conversions delivering a master suite and additional bedrooms; and heritage conservation projects that require the highest levels of craftsmanship in stone, brick, timber and plaster. Interior finish specifications routinely include marble in principal bathrooms, hardwood floors laid to a bespoke pattern, hand-finished joinery in kitchens, wardrobes and staircases, and concealed MEP throughout. Every project is delivered under a single fixed-price contract with a defined programme and staged payments tied to milestones.

Why Prime Build for your Hampstead home

Hampstead clients often tell us they interviewed multiple builders and chose us for three reasons. First, discretion: we run quiet, secure sites, we brief the team to represent the home appropriately, and we manage neighbour communication and deliveries to minimise any impact on the street. Second, craftsmanship: our in-house joinery, our long-standing tile and stone partners, and our decorators deliver work at a level of finish that stands up to interior designers and architects working at the top of the London market. Third, planning discipline: Camden planning is exacting, and we handle every submission — householder applications, Listed Building Consent, conservation area justifications, and party-wall procedures — as part of our contract. The result is a project where nothing surprises you.
