What an architect does.

The whole job. And when you do not need one.

Reviewed August 2026
The short answer

An architect takes a project from first idea to finished building: testing what the site will support, designing the scheme, winning consents, producing the drawings it is built from, and administering the contract on site. The work splits into eight RIBA stages. Instruct all of them, or only the ones you need.

In practice · Princethorpe, near Rugby

A private house, first survey to handover

The clearest way to answer the question is to walk one house from end to end.

The order of work
01Survey and briefWhat the site allows, and what the owners wanted.
02Design and consentThe house, then the permission for it.
03Working drawingsThe information it gets built from.
04Site to handoverAdministered through construction to completion.

A redundant air-ambulance headquarters on Burnthurst Lane at Princethorpe, empty since 2016 and standing in the Green Belt. A private couple wanted a home there instead.

The Green Belt is the constraint that shapes everything here: what you are allowed to build is measured against what already stands.

The house we designed is a four-bedroom home of 362 square metres with a detached garage, on a site of just over an acre. Permission for it was granted in July 2019, with eleven conditions attached to it.

Then the technical design, and then the build. It was completed and occupied in 2023.

A computer-generated image of the house at design stage, seen across a wildflower meadow at dusk: a long form with a pale gable, standing-seam roofs, a glazed link and a timber-clad wing. A photograph of the same house completed, from the same viewpoint in evening light: coursed stone gable, vertical timber cladding weathered to grey, standing-seam metal roofs, and planting along the terrace.
The same view designed and built. Above, a computer-generated image from the design stage. Below, a photograph of the completed house.

That is the whole arc, and it is the part that matters most on a private house: the same practice from the first survey to the keys. Nobody handed it on at the consent, and nobody had to be brought up to speed halfway through.

Because the size of what you may build is set by what is already there, the design and the planning case have to be worked out together rather than one after the other. On a constrained site that is the whole job, and it is why the drawings and the argument cannot be produced in sequence by different people.

The house is coursed stone gables under vertical timber cladding and standing-seam metal roofs, heated by an air-source heat pump and served by off-mains drainage.

The proof

Four homes, four different problems.

Extension · consented and delivered

Weedon, Northamptonshire

A contemporary house this practice designed years earlier. Its new owner came back to extend it: the open undercroft beneath the cantilevered first floor infilled to make a studio, and a detached two-bay car port added in matching timber.

Barn conversion · two homes

Green Gate Barns, Earlswood

A redundant steel-framed agricultural barn near Solihull, taken to two houses inside the existing shell through Class Q prior approval. Approved in forty-three days, well inside the window, then the materials condition discharged and the barns built.

Family home · concept to consent

Ashlawn Road, Rugby

A countryside family home on the edge of Rugby, taken from first concept through to consent. A design objection and a protected bat roost both had to be answered along the way, and the ecology condition was discharged twenty-three days early.

Rugby Borough Council · consented, condition discharged
Listed farmstead · dual consent

Barby Wood Farmhouse

A late-eighteenth-century ironstone farmhouse and three curtilage-listed outbuildings, brought together into one home of 477 square metres. Listed building consent and full planning permission were granted five days apart.

West Northamptonshire Council · both granted February 2025

The first step

Not sure what you actually need?

Send us your project and where it is. A Senior Architect will give you an initial appraisal and guide you as to what to do next.

Start a conversation
01 · Where you stand

First, check whether you need one at all

No law says you must use an architect. For a great deal of ordinary work you do not need one, and a good architectural designer or technologist will produce what you need for less.

A straightforward rear extension inside permitted development, a loft conversion with no planning question hanging over it, a like-for-like replacement: those are drawing jobs. Buying eight stages of design for them is buying something you will never use.

More

It changes when the outcome is uncertain. A constrained or contested site. A listed building or a conservation area. A scheme whose value depends on the design being right. Or a project large enough that the technical information has to be correct first time. On those, the fee is not what the drawings cost. It is what the risk costs.

The test worth applying is a simple one. If you already know what you are building and the only real question is how to draw it, then what you need is a drawing.

If the question is what can be built here at all, and whether anyone will grant it, that is a different job with a different kind of risk attached. Work out which one you have before you ask anyone for a fee.

02 · The difference

Where an architect differs from a designer

Four differences, and only the first is about the word itself. None of them is about talent.

Difference 01

The word architect is protected by law

Section 20 of the Architects Act 1997 says nobody may practise or trade under a name or title containing the word unless they are on the Architects Register. The only exceptions are naval, landscape and golf-course architects.

What it means: anyone at all may do the work. Only a registered architect may use the word.
Difference 02

Someone independent to complain to

A registered architect works to a statutory code, has to hold insurance, and answers to the Architects Registration Board. Someone practising as an architectural consultant or designer sits outside that regime, because only the one word is protected.

What it means: a route of redress that does not depend on the practice agreeing with you.
Difference 03

Chartered is a second check again

A RIBA Chartered Practice must put all architectural work under the personal supervision of a chartered architect, and hold professional indemnity cover, a quality management system and health, safety and environmental policies. Practices are audited at random.

What it means: the standard is checked by somebody other than the practice claiming it.
Difference 04

A public record you can check yourself

Every planning application a practice submits in its own name lands on a council register that anyone can search, and so does every decision. Whatever a practice tells you about its record, the councils have already written it down.

What it means: every consent named on this page is recorded on a council's public register.
03 · The stages

The eight stages, and which ones you buy

The RIBA Plan of Work splits every project into eight stages. It is the industry's shared language, and it is also how fees are structured, so knowing which stages you are paying for is most of understanding a quote.

RIBA Plan of Work 2020
0Strategic DefinitionIs a building even the right answer?
1Preparation and BriefingThe brief, the budget, the site appraisals.
2Concept DesignThe architectural concept, agreed with you.
3Spatial CoordinationThe design tested and coordinated. Planning usually goes in here.
4Technical DesignEverything needed to actually build it.
5Manufacturing and ConstructionBuilt. The architect answers site queries.
6HandoverHanded over, the contract concluded.
7UseIn use, with aftercare and evaluation.

Most projects run from Stage 1 to Stage 6. Stage 0 asks whether to start at all, and Stage 7 covers the building in use, for as long as it stands.

You do not have to buy all of it. A common appointment for a private client is Stages 0 to 3, which takes you to a planning decision and a clean point to stop and think. Princethorpe above was 0 to 7.

More

Stages 0 and 1 need no design team at all. They are the brief, the budget and the site appraisal, and they are the point at which a project is cheapest to change. Skipping them is the most expensive saving on offer.

Stages 4 and 5 overlap on most projects, and there is no design work in Stage 5 beyond answering queries from site. If a scheme is still being designed while it is being built, something went wrong further back.

Common questions

Working with an architect, answered

When should I bring an architect in?

Early, and ideally before the scheme is fixed.

More

The cheapest place to test an idea is at feasibility, before money has been committed to a route. Early involvement lets an architect shape the brief, test what the site and the budget will actually support, and rule out an approach planning will not accept. Bringing someone in after a scheme has been settled usually means paying twice: once for the original design, and again to fix what will not get through.

Does an architect help with planning permission?

Yes, and on a difficult site it is often the main reason to appoint one.

More

The work is designing a scheme that fits local planning policy, preparing and submitting the application, answering the council's questions while it is determined, and building the evidence case where the site is contested. Under the RIBA Plan of Work the application usually goes in at the end of Stage 3, which means the planning strategy has to be settled during the design stages before it, not added afterwards.

What does an architect cost?

It depends on the scale and complexity of the project, and on which RIBA stages you instruct.

More

Fees are usually structured as a percentage of construction cost, a fixed fee, or a stage or hourly rate, and the same building can carry very different fees depending on how much of the eight stages you buy. A feasibility study is a small commitment by design, because its whole purpose is to tell you cheaply whether the rest is worth doing. Ask any practice which stages a quoted fee covers, and what you receive at the end of each one.

Can I appoint an architect for only part of a project?

Yes. The eight stages exist partly so that an appointment can start and stop at a defined point.

More

A common arrangement is to instruct Stages 0 to 3, which takes a project to a planning decision, and then to decide separately whether to carry on into technical design and construction. Others appoint from Stage 4 onwards, to take a consent that already exists and produce the information the building will actually be built from. What matters is that both sides know which stage the appointment ends at, and what is handed over when it does.

What is the difference between an architect and a structural engineer?

An architect designs what the building is; a structural engineer works out what holds it up.

More

The two work alongside each other rather than in competition. An architect is responsible for the design as a whole: the brief, the spatial arrangement, the appearance, the consents, and usually the coordination of everyone else on the team. A structural engineer is a specialist consultant who designs the frame, the foundations and the load paths, and takes responsibility for those calculations. On most projects the architect coordinates the engineer as part of the design team.

Does an architect manage the building work?

An architect can administer the building contract, which is not the same as managing the site.

More

Under a traditional contract the architect acts as contract administrator: inspecting progress at intervals, certifying payments, issuing instructions, dealing with the contractor's queries, and certifying practical completion at the end. The contractor stays responsible for how the work is carried out and for safety on site. Some clients instead appoint a project manager, or use a design-and-build contract under which the contractor takes on the design as well.

How do I check that someone really is an architect?

Search the Architects Register, which the Architects Registration Board keeps and publishes.

More

If a person is not on the Register they are not a UK architect, whatever the business name suggests. A practice can be checked separately: RIBA publishes its list of Chartered Practices, and any planning application a practice has submitted in its own name appears on the relevant council's public register with the decision attached. Between them those three sources will tell you more than a portfolio will.
