B β€” Capabilities

A single studio, every discipline a home requires.

One team of architects, designers and site managers carries the project from first sketch to final walkthrough β€” sixteen specialised disciplines under one contract.

Build / 01

Full Home Renovation

  • Object Sourcing
Wet / 05

Bathroom Remodeling

  • Remote Monitoring
Life Safety / 11

  • Certificate Issuance
Energy / 14

  • Pre-Purchase Surveys
  • Post-Reno Valuations
  • Curated Listings
Finance / 16

Home Mortgage

Mortgage advisory and broker introduction for renovation-led purchases and refinance after build. We prepare the lender-ready documentation β€” plans, specifications, contractor quotes and timelines β€” so the loan reflects the post-renovation value, not just the purchase price.

D β€” How We Work

A fixed nine-stage process, on every project.

The same disciplined sequence runs through every commission β€” whether it is a single bathroom or a ground-up new build β€” so nothing is left to chance and nothing is improvised on site.

Stage 01 β€” Consultation

We listen before we draw.

A principal architect visits your property, walks every room and asks detailed questions about how the space is actually used day-to-day β€” cooking habits, morning light, storage pain points, hosting patterns, accessibility, future plans. This conversation forms the brief, not a checklist. We leave with measurements, photographs and a written record of your priorities, which we then use as the test for every design decision that follows.

Duration Β· 1 Site Visit + 1 Studio Day
Stage 02 β€” Planning & Feasibility

Feasibility, budget and permits.

Our planning team commissions structural surveys, soil reports where relevant, zoning checks and a full permit-pathway review before any design work begins. We confirm what is legally and structurally possible, prepare an early budget range with a 10% contingency and identify any approvals required β€” listed building, conservation area, party wall or planning permission β€” so the design phase starts with certainty rather than hope.

Duration Β· 2–4 Weeks
Stage 03 β€” Concept Design

The first set of drawings.

We present two or three concept directions in plan, section and 3D sketch β€” each with a clear spatial logic, material direction and a distinct character rather than cosmetic variations. You review, we refine. By the end of this stage you have a single agreed direction, a fixed scope and a confidence that the design solves the brief, not just decorates around it.

Duration Β· 3–5 Weeks
Stage 04 β€” Detailed Design

Fully detailed construction plans.

The agreed concept is developed into a complete construction drawing set β€” millwork details, lighting layouts, electrical and low-voltage plans, plumbing schematics, finishes schedule, joinery cutting lists and a specification document that names every product, manufacturer and material. Nothing on site is left to the contractor's interpretation; the design is the contract.

Duration Β· 4–8 Weeks
Stage 05 β€” Approval & Contract

Sign-off, fixed price, contract.

You review the full drawing set and specification, ask any final questions, and once you are satisfied we issue a fixed-price construction contract. There is no estimate, no allowance schedule and no "subject to site conditions" clause. The number you sign is the number you pay unless you request a written change order yourself.

Duration Β· 1–2 Weeks
Stage 06 β€” Construction

Weekly reporting, on site daily.

Our own project manager runs the site every working day, with trade teams employed directly by the studio rather than sub-contracted to the lowest bidder. You receive a weekly written report with photographs, programme update, items resolved and items pending. A live cost sheet keeps the running spend against the contract figure visible at all times.

Duration Β· 3–12 Months
Stage 07 β€” Quality Check

A 200-point inspection.

Before anything is called finished, an independent snagging inspector walks the property against a 200-point checklist β€” covering structure, finishes, mechanical performance, acoustics, lighting levels and accessibility. Every defect is logged, photographed and assigned to a trade for resolution before the handover walk is scheduled.

Duration Β· 1–2 Weeks
Stage 08 β€” Delivery & Handover

Walkthrough & handover pack.

You walk the finished home with the principal architect and project manager. We hand over a complete documentation pack β€” as-built drawings, material schedules, warranties, maintenance guides, appliance manuals, spare parts and a list of recommended care products β€” so you can keep the home in the condition it was delivered.

Duration Β· 1 Day
Stage 09 β€” Post-Occupancy Support

Two years, on call.

A dedicated line to your project manager stays open for two years after handover. Snagging issues, settling adjustments, seasonal maintenance questions and small refinements are all handled through the same team that built the home β€” no call centres, no third-party warranties to chase, no anonymous service technicians.

Duration Β· 24 Months

Questions

Before you reach out.

Most whole-home projects run 12–18 months from signed contract to handover, depending on the scope, square footage and the condition of the existing structure. Single-room renovations typically take 8–14 weeks. We provide a programme at concept stage that breaks the build down week by week, and we update it every Friday as part of our weekly site report β€” so you always know where the project sits against the original timeline and what is happening next.

Yes. Once you sign the construction contract, the price is fixed for the scope described in the drawings and specification. Any variation β€” whether initiated by you, by a site condition, or by a building control requirement β€” is documented as a written change order with a clear price and time impact before the work proceeds. We never present an unexpected invoice. If a cost arises that we should have foreseen, we absorb it; that is the point of a fixed-price contract.

Yes, in full. Our planning team files and manages every application on your behalf β€” including planning permission, listed building consent, building regulations approval, party wall agreements and any freeholder or management company consents. We attend site visits with conservation officers and building control inspectors, respond to any queries they raise and keep you informed of progress. You will not be asked to deal with an authority directly unless your signature is legally required.

For partial renovations of single rooms or floors, it is often possible to remain in the home β€” we seal off working zones with dust barriers, manage access and agree working hours in advance. For full gut renovations or works involving major structural change, the kitchen or both bathrooms, we strongly recommend relocating for the construction phase. We will advise clearly at quotation stage which option suits your specific scope, and we can recommend short-let partners in your area if helpful.

We currently operate across more than 40 cities in Europe and North America, with active studios in London, Paris, Milan, Geneva, ZΓΌrich and New York. For projects outside these cities we travel with the same team rather than sub-contract locally β€” the quality standard is the studio's, not a regional partner's. If your location is not listed, please ask; we take on a small number of remote commissions each year where the brief is right.

Payments follow the construction programme in clearly defined stage payments β€” typically a deposit on contract signing, then instalments at structural completion, first-fix, second-fix and handover. Each stage payment is invoiced only when that stage is genuinely complete and signed off, never in advance of the work. We provide the full payment schedule inside the contract so there are no surprises, and any retention is released after the post-occupancy inspection.

Every project carries a 10-year structural and workmanship warranty on the build, alongside manufacturer warranties for appliances, glazing, roofing and mechanical systems β€” all documented in the handover pack. In addition, we provide two years of post-occupancy support during which any snagging or settling issue is handled by the same site team that built the home. Warranties are transferable to new owners if the property is sold.

We can, but we rarely recommend it. The reason we deliver on time and on budget is that the same studio designs and builds β€” the people who drew the plans are accountable for the build. Where we do collaborate with an external architect, we ask to be involved at detailed design stage so the drawings are buildable to our standard. We are happy to discuss the arrangement honestly once we understand the project.
