Every discipline. One studio. One contract.

Our RIBA architect partners lead every project from initial concept through to the technical pack that goes on site. Because the drawings are produced inside the studio that will build them, we close the usual coordination gap between design intent and buildability — the place where most overruns are born.

We work primarily on London period stock: Georgian terraces, Victorian semis, Edwardian villas, mansion blocks and converted warehouses. That experience means we already know how Camden, Westminster, RBKC and the City of London assess most applications, where the conservation triggers sit, and how to engage planning officers early to avoid late-stage refusals.

Outputs include feasibility studies, pre-application packs, full planning submissions, heritage statements, design and access statements, Building Regulations technical drawings, tender packs, and stage-by-stage 3D visualisations to keep the client decision-confident throughout design development.

Structural engineering sits inside the studio rather than out-sourced — which is the single biggest reason our build programmes stay on track. Calculations are produced in lock-step with the architectural drawings, removing the back-and-forth that normally happens between separate design and engineering teams.

We cover everything residential refurbishment and extension projects require: steel-beam design for layout changes, underpinning for subsidence remediation, basement excavation engineering with party-wall coordination, foundation analysis for new extensions, and remedial structural works for period properties with historic movement.

Every package includes the calcs pack, structural drawings, specification, and the SE’s input through to Building Control sign-off — you are not handed a calculation report and told to find a contractor; the same studio delivers the calc and then builds to it.

Surveying sits one step away from design-and-build for a reason: the advice has to be independent. We deliver every RICS instruction through our sister practice, Hampstead Chartered Surveyors — a separately regulated firm of chartered surveyors operating under a distinct brand and engagement.

Because they sit beside the renovation studio, you can commission a Level 2 HomeBuyer or Level 3 Building Survey before exchange, then have the findings priced and remediated by Hampstead Renovations under one continuous relationship — with zero conflict of interest at the survey stage.

Typical instructions include defect diagnosis on period properties, schedule-of-condition surveys ahead of major works, reinstatement cost assessments for insurance, and dilapidations advice for end-of-lease commercial and residential properties.

Most of our work happens inside Hampstead, Highgate, Belsize Park, St John’s Wood, Marylebone, Mayfair, Belgravia, Kensington and Chelsea — which means most of our work touches a conservation area, an Article 4 designation, or a listed building. Heritage isn’t a side service for us; it’s the default operating mode.

We hold pre-application meetings with conservation officers in advance of every sensitive application, produce Heritage Impact Assessments where required, and detail period elements at a level of specificity that planning officers consistently accept on first submission. Listed-building consent applications are handled in-house from the heritage statement through to discharge of conditions.

On site, the craft side of heritage matters as much as the paperwork. Lime-mortar repointing, hand-run plasterwork cornices, restored sash windows, repaired stone steps, period-correct paint specification and salvaged ironmongery are all delivered by long-standing trade partners who have worked alongside us across the wider studio team for years.

Refurbishment is the largest single category of work we deliver. To make budgeting honest from the first conversation, we present every project in one of three tiers — with indicative £/sqm bands published below. These bands are guidance, not quotes; the fixed contract is set after the technical design stage, never before.

Across all tiers we deliver everything inside the contract: strip-out and protection, structural alterations, complete re-services (electrics, plumbing, heating, ventilation, smart-home), plasterwork, joinery, kitchens, bathrooms, decorating, flooring, FF&E and final clean. There is no separate ‘main contractor’ layered on top — we are the main contractor.

For mansion-block and lateral-flat works we handle the additional layer of leasehold approvals, building-manager liaison, Section 20 implications where relevant, and the access logistics that make the difference between a smooth job and an angry building.

Extensions are the most-litigated category of London residential work — planning officers are sensitive, neighbours are sensitive, and the Party Wall Act 1996 turns every shared boundary into a process. We carry every part of that process internally: pre-app conversation, planning submission, party-wall award coordination, structural calcs, Building Control, and the build itself.

Typologies we deliver weekly include rear extensions (typically 3–6m deep), side-return infills on Victorian terraces, full L-shaped wrap-arounds, double-storey rear additions, contemporary glass-box additions where consented, and traditional orangeries with structural lantern roofs.

Every extension is detailed with airtightness, thermal bridging and Part L performance considered from the first sketch — not retrofitted at Building Regs stage. That is the difference between a comfortable, low-bill extension and one that overheats in summer and condenses in winter.

Loft conversions and basements are the two highest-value-per-sqm interventions on a London property. Both are also the most engineering-intensive: lofts need structural floor design, mansard-roof framing and fire-strategy compliance; basements need underpinning, waterproofing tanking, drainage strategy and party-wall coordination at every shared boundary.

For lofts we deliver dormer, mansard, hip-to-gable and L-shaped configurations, plus simpler Velux conversions on suitable roofs. Every loft is detailed with Part B fire compliance (protected stairs, fire doors, mains-linked detection) and Part L thermal performance from the outset.

For basements we hold to a single specification standard: dual waterproofing (Type A barrier + Type C cavity-drainage), fully tanked sumps with twin-pump and battery backup, MVHR with humidity control, and full warranty backing. We do not deliver single-skin Type-A-only basements; the moisture risk is too high to be acceptable on prime stock.

Kitchens and bathrooms are sold elsewhere as box-shifting categories: choose a slab, choose a tap, install. We treat them as bespoke design problems. Every kitchen we deliver is drawn to the millimetre to the room it sits in; every bathroom is detailed for its specific stone, sanitaryware, drainage and ventilation strategy.

On the kitchen side we work in shaker, contemporary slab, handleless, industrial and traditional in-frame styles — with cabinetry produced either by our partner UK joinery workshops or by specified premium imports (Bulthaup, Boffi, Poliform, Eggersmann) where the brief warrants it. Stone, appliances, ventilation and lighting are all integrated into one drawing pack.

On the bathroom side we focus on wet-rooms, en-suites, family bathrooms and cloakrooms — with primary attention paid to the unglamorous half: drainage falls, waterproofing, ventilation, acoustic separation and access for maintenance. The visible half — stone, brassware, joinery, lighting — is the easy part once the unseen half is right.

The category that distinguishes a premium project from a competent one is usually the specialist rooms: a properly acoustically isolated cinema; a gym with rubber-on-acoustic-mat floor build-up rather than a mat-on-concrete approximation; a wine cellar with vibration isolation and humidity control; a wardrobe room with the lighting and joinery of a retail boutique.

These rooms reward investment more than almost any other — because they’re used daily, they’re visible to guests, and they almost always fail catastrophically if the underlying technical detailing is wrong. We delivery every wellness and specialist room as an engineered package, not an aesthetic exercise.

Mechanical, Electrical and Plumbing (MEP) is where most renovations either succeed or quietly fail. A house can have an immaculate kitchen and still be uncomfortable, noisy, expensive to run, or unsafe. Our default specification on every project includes Part L heat-loss modelling, ventilation strategy (MVHR where applicable), zoned heating, smart lighting infrastructure and full Part P-compliant electrical installations.

Exteriors are the second half of the building envelope — roofing, guttering, rendering, brickwork, paving and landscaping. We treat them as part of the same project rather than a separate trade contract, so the warranty and contractual liability sit with one party.

Most builders disappear at hand-over. We deliberately built our process so that the project lead who delivered the build is the same person who answers the phone twelve months later when a tap drips or a door catches in damp weather. The relationship continues across our 24-month workmanship guarantee, the manufacturer’s warranties (passed straight to you in your O&M manual), and the planned-maintenance contract that many of our clients opt into post-project.

For clients with multiple properties — investment portfolios, family homes plus country properties, or rental holdings — we offer a managed-property aftercare contract through our sister app brand, Hampstead On Demand, which handles small jobs, emergencies and seasonal maintenance.
