The short answer

What does a residential architect do?

A residential architect designs homes and home projects — extensions, loft conversions, basements, refurbishments and reconfigurations — guiding each stage from brief and feasibility through planning and building regulations to construction. We test what your property and its planning context allow, resolve a design that is both beautiful and buildable, and coordinate the engineers and consultants a project needs.

A full architectural service, not just drawings

A good residential project is a sequence of decisions made in the right order: understanding the brief, testing what the property and planning context allow, developing a design that is both beautiful and buildable, securing approvals, and producing the technical information a builder needs. We work through the RIBA Plan of Work so each stage builds on the last, rather than producing a set of attractive drawings that fall apart when they meet planning policy, party walls or a builder’s price.

That structure matters across London, where residential projects often carry a constraint — a conservation area, a lease, a shared wall, a tight plot or period fabric that needs care. Our role is to hold the whole picture together, so the design you fall in love with is the same design that gets approved and built.

Design quality, buildability and long-term value

We design for how you actually live — light, flow, storage and the relationship between the main spaces and the garden or outlook — while keeping a clear eye on what it will cost to build and how it will perform over time. Calm, well-detailed architecture that respects the building tends to add more lasting value than fashionable gestures, particularly in heritage settings where restraint is rewarded.

When to bring an architect in

The earlier the better, and earlier than most people assume. The decisions that shape a project’s cost and success — what to build, whether the property can take it, how to phase it — are made at the very start, so involving an architect at feasibility, even before you buy, is where the value is greatest. Coming in late, once a builder has sketched something or a scheme is half-formed, usually means unpicking decisions made without testing the planning position or the building. We are happy to start with a short feasibility appraisal so you can commit with your eyes open.

What we design — across the whole journey

We work across the full range of London home projects: rear, side-return, wraparound and two-storey extensions; loft conversions and basements; whole-house refurbishment and reconfiguration; flat refurbishment and Licence to Alter work; and sensitive work to period, listed and conservation-area properties. Keeping the whole journey — feasibility, design, planning, technical drawings and construction support — under one roof means the design intent is carried through rather than handed off and diluted at each stage.

Accessible and lifetime homes

We design homes to work for the whole of life, not just today. Where a project needs to accommodate changing mobility, multi-generational living or a specific access requirement, we build that into the architecture from the outset — step-free approaches and level thresholds, doorways and circulation sized for wheelchair and frame use, ground-floor or through-floor lift provision, accessible bathrooms and wet rooms, and considered handrail, lighting and contrast detailing. Designing for accessibility and adaptability early, alongside the wider scheme, is far cheaper and far more elegant than retrofitting it later, and it keeps a home comfortable and valuable as needs change. We coordinate Part M compliance and any occupational-therapy or access-consultant input as part of the appointment.

How an appointment works

Architectural work follows the RIBA Plan of Work, and an appointment can follow the same stages: feasibility and briefing, concept design, planning, technical design, and support during construction. You can appoint us for the whole journey or stage by stage, which keeps the commitment proportionate and lets you make a confident decision before each step. We agree the scope, the deliverables and the basis of our fee in writing at the outset, so you always know what you are getting and what comes next.

What a good residential appointment actually delivers

Homeowners often buy “an architect” when they really need a sequence: a realistic brief, a planning or freeholder route that matches the property, drawings that can be validated, and technical information a builder can price. A residential appointment should make that sequence visible. Feasibility tests options against structure, daylight, budget direction and approval risk. Design then freezes a preferred option. Planning or Licence to Alter packs make the case to the people who must consent. Building regulations drawings and engineer coordination turn the approved idea into something that can be built without improvisation on site.

The value is coordination as much as sketching. London houses and flats almost always need other professionals — structural engineers, party wall surveyors, sometimes heritage or acoustic input. An appointment that only produces pretty plans and leaves those strands disconnected tends to cost more later, not less. We keep one measured model and one design story so the same project is not redesigned three times for three audiences.

How to know which stage you need first

Not every project should open with a full design service. If you only need to know whether a rear extension is realistic, start with a route review or feasibility. If the design is settled and the council needs a package, start with planning drawings. If permission is already granted, start with building regulations drawings. If you hold a long lease, freeholder requirements may sit beside or ahead of planning. Matching the first fee to the real question is the most people-friendly way to run a project — and it is how fixed fees stay fixed.

Bring an address, photos and a short written brief to the first conversation. That is enough for an honest path. Tools on this site — the planning checker, drawings selector and package finder — help you frame the question before you write. Local pages for your area and project type then show the constraints we will check on the pin, not a generic London paragraph.

What we produce

Typical deliverables

  • Brief development and feasibility options
  • Measured survey and existing drawings
  • Concept design and design development
  • Accessible and lifetime-home design where needed
  • Planning drawings and supporting documents
  • Building regulations and technical drawings
  • Structural engineer and consultant coordination

London-specific

What to keep in mind

  • Conservation areas and Article 4 directions frequently restrict permitted development
  • Leasehold flats usually need freeholder consent through a Licence to Alter
  • Party wall matters arise on most terraced and semi-detached sites
  • Daylight, sunlight and overlooking are assessed closely by London boroughs
  • Period fabric, damp and dated services need to be understood before design

How the process works

From first call to completion

  1. Brief & feasibility

    We discuss your objectives and test what the property and planning context allow.

  2. Concept design

    We develop options against budget, buildability and approvals.

  3. Planning

    We prepare and coordinate the planning application where needed.

  4. Technical design

    We produce building regulations and construction information.

  5. Tender

    We help you obtain and compare builder prices on a consistent basis.

  6. Construction support

    We answer queries and, where appointed, administer the contract to completion.

Avoiding pitfalls

Common risks & mistakes

  • Treating planning drawings as if they were construction drawings
  • Committing to a design before testing the planning position
  • Overlooking freeholder consent on leasehold flats
  • Leaving structural coordination until too late
  • Pricing a build from incomplete information

Frequently asked questions

Do I need an architect for a London house project?

Many homeowners appoint an architect or architectural designer to assess feasibility, prepare drawings, develop the design and support planning and building regulations. The right appointment depends on the property, the scope and whether you also need structural engineering or contractor tender support.

What is the RIBA Plan of Work?

It is the industry framework that breaks a project into stages, from strategic definition and briefing through concept and technical design to construction and handover. We use it so each stage is properly resolved before the next begins.

Can you take a project all the way to completion?

Yes. We can support feasibility and planning only, or provide a fuller service through technical design, tender and construction-stage support, including contract administration where we are appointed and insured for it.

Will you guarantee planning permission?

No one can. We design to give a proposal the best reasonable prospect by considering policy, context and amenity early, but the decision rests with the local planning authority.

Do you provide measured surveys and structural calculations?

We provide measured building surveys in-house, producing accurate existing drawings. Structural calculations are produced by a structural engineer, whom we coordinate and whose information we incorporate into our drawings.

Can you design an accessible or lifetime home?

Yes. We design for accessibility and adaptability as part of the residential service — step-free access, level thresholds, wider circulation, accessible bathrooms, and lift or through-floor provision where needed — building it in from the outset rather than retrofitting later. We coordinate Part M compliance and any access-consultant or occupational-therapy input required.

How much do residential architects charge in London?

Fees depend on the scope and how far you take a project — feasibility only, planning, or a full service through technical design and construction. We work to fixed, quoted fees agreed in writing before you commit, starting with a £395 route review that is credited against your project if you proceed. See our /packages/ page for how the stages and fees are structured.

How long does a residential architecture project take from first meeting to completion?

There is no single figure, because a residential appointment is a sequence rather than a task. Feasibility and briefing come first, then an accurate measured survey, then concept design and the rounds of review that settle it, then any application, then technical design, tender and construction support. Only one stage carries a published period: once a valid householder planning application is submitted, the local authority's statutory target is around eight weeks, and sensitive or contested proposals often run beyond it. Everything either side moves with scope — how quickly survey access is arranged, how many options you want tested, whether structural or heritage input is needed, and how promptly decisions are made at each stage. We agree the scope and fee stage by stage, and each stage's dates are fixed as the previous one closes rather than guessed at the outset. Our guide to how long a London extension takes sets out the same sequence stage by stage.
