Architect vs architectural designer: what’s the difference?

The term “architect” is a protected title under UK law. The only people allowed to use the term are those who have been through formal training and passed exams. They must also be registered with the Architects Registration Board (ARB). Think of an architectural designer as a drafter or helper who can work on a project. They can take you so far but not beyond.

In this guide, you’ll learn why a registered architect gives you more than drawings and more than basic architectural design services. You’ll see what happens at each stage of the design process, what they are responsible for, and when an architectural designer might be acceptable for a smaller job.

What an architect does: summary

A registered architect takes responsibility across the entire process. We’ll go into more detail later in the article but here’s an overview of how they contribute towards your project:

Concept designs: Turning your vision into early sketches and spatial plans that show how the building could work
Planning drawings: Producing to-scale drawings that meet local authority standards. This includes elevations, sections and site layouts that show the scale, appearance and layout of the proposal.
Managing the planning application: Preparing and submitting the full application pack. The pack features required scaled drawings, supporting statements and drawings. That could include the Design and Access/Planning Statements and forms like the Ownership Certificate. They are experts at gaining permission for complex jobs like house extensions, outbuildings and additional storeys.
Overseeing revisions: Responding to planner feedback and updating the design if needed. This is often key to getting your project through planning approval.
Liaising with the council: Handling questions, objections and clarification requests. To-and-forth between architects and planners resolves issues early and keeps your project progressing. They can help you deal with neighbour complaints where planning permission is needed, for example, if you’re changing a Use Class C3 residential property into an HMO.

Technical drawings: Adding construction detail and depth to project drawings and blueprints. This can include floor build-ups, roof structure, insulation, drainage and fire protection. This expertise is vital, for example, in HMOs to meet Part B fire protection standards.
Construction drawings: Preparing the final buildable set of drawings that meet Building Regulations. These drawings also give your contractor clear guidance on how to build each part of the project.
Coordinating the team: Working with structural engineers, surveyors and contractors on the job. This is to make sure the project matches what’s in the drawings and runs to schedule.

An architect is there at each stage of your development. They are the one person responsible for making sure your design works, your plans get approved, and your build stays on track.

What an architect does: step-by-step

Registered architects take control over the workflow of a construction project. It starts with a set or drawings that the architect turns into viable plans. At the end, they deliver a buildable, safe design that balances aesthetics with a functional layout.

Step one: site analysis and concept design

Every architectural project starts with getting an understanding of the site. The architect will visit, measure and assess the existing buildings, boundaries and layout of a proposed project. This is to check your project is actually feasible before they start work on any drawings.

They review:

Planning constraints: Check for restrictions like listed status, conservation areas, flood zones or Article 4 Directions
Local policy: See what your council allows in terms of height, use, style, density or space standards
Site access: Make sure there’s a way to bring in materials, equipment and trades safely
Services: Check how power, water, drainage and telecoms reach the site and whether upgrades are needed
Space: Understand the layout, orientation and limits of the plot to see how much usable room there is
Project scope: Confirm what you want to do and whether the site can realistically support it.
Early risks: Flag any structural or planning issues that could delay or block the project later on

If they determine that your project is feasible, they then begin the design process. They’ll create initial sketches, layouts and architectural drawings. Architectural drawings are scaled plans and elevations that show size, layout and appearance.

This helps you, the client, see the outcome of your vision more clearly. You’ll understand the shape, function and flow of the building and how it supports day-to-day life.

This is a vital part of every project. That’s whether you’re planning a loft conversion, home extension, new build or commercial projects like offices. You’ll know the project can work. Good planning always cuts cost and time, so you avoid surprises later on.

Step two: planning applications and permissions

Architects prepare the planning application and create the supporting architectural drawings. They also manage the important back-and-forth contact with the local authority.

The steps in this part of the process include:

Create planning drawings: Produce clear, scaled drawings that meet local authority standards. They also show how your project will fit the shape of the site and relate to neighbouring buildings.
Prepare supporting statements: Write design and access statements, planning statements and heritage notes. Design and access statements show how people enter, move through and use your building. Heritage notes show how a project respects and responds to a listed building or conservation area. These statements help planners more easily see how your designs fits within council policies.
Liaise with the council: Handle interactions with planners to clarify details about the project. This greatly reduces the risk of rejection or approval with restrictive or costly conditions.
Manage revisions: Respond to objections or feedback and update the design if needed. Once this stage is over, it’s their job to guide the scheme through to final approval.

Because they understand the planning process, architects are often able to pre-empt objections. This reduces the risk of months wasted tweaking with a design to get it through at the second or third attempt.

Step three: technical drawings and building regulations

Once your project has got planning permission, Building Regulations approval is another. You must involve Building Control for almost all building work beyond basic cosmetic changes. Building Control checks that your project meets legal standards for safety, structure, energy efficiency and accessibility.

At this stage, your architect creates technical drawings and construction drawings that:

Structural layout: Plans showing the walls, beams, foundations, roof structure and load-bearing walls
Build detail: Wall, floor and roof build-ups showing materials, layers and construction methods
Regulatory compliance: Details on insulation, drainage, fire safety, ventilation and disabled access
Construction detail: Precise sections and junctions to guide contractors working on a job. These details are also needed to satisfy Building Control inspectors.

They also work closely with structural engineers to check all load-bearing elements. A load-bearing element is any part of the structure, such as a wall, beam or floor, that supports weight from above.

Building Control liaises with the local authority or Registered Building Control Approver. This is to gain Building Regulations approval.

There is a different regime for higher-risk buildings. A higher-risk building might be a residential block that is at least seven storeys or 18 metres tall. It could also be a care home or hospital where people stay overnight. In these situations, the Building Safety Regulator issues a completion certificate. The certificate states that the building meets safety standards and Building Regulations. This means it’s now ready for occupation.

For all other cases, it’s the local authority or RBCA who signs it off, not the architect. Some elements, like electrics or boilers, may be self-certified under a competent person scheme.

Step four: coordination with the build team

You can also appoint your architect to work with the building team on project delivery. Clients can nominate their architect as a:

Contract Administrator: Manages the building contract and certifies payments. They also resolve disputes between you and the contractor.
Principal Designer (Construction): Oversees health and safety on site and manages risk information. They’re also responsible for ensuring legal duties are met under CDM Regulations.

Elements of these roles include:

Acting as Contract Administrator: Managing contract terms, approving stage payments, and keeping records
Liaising with the contractor: Working with the main contractor and specialist trades to resolve issues
Visiting the site: Checking progress and comparing it to the approved drawings and specification
Managing technical queries: Answering questions about design, layout or construction detail
Checking compliance: Making sure the works match the agreed design and meet relevant standards

This support helps keep the build on track and avoids misunderstandings. It also gives you confidence that the project is being delivered as planned.

When an architectural designer may be enough

There are some jobs that an architectural designer might be suitable for, including:

Internal layout changes that don’t affect structure
A small loft conversion or garden room
A simple home extension under permitted development
Early ideas for a building before formal planning

A designer can prepare drawings, assist with some planning tasks, and help you shape ideas. They’re often a lot cheaper than a registered architect.

But restrict their involvement as much as you can in your build because they don’t have the training or experience. Don’t rely on them to get you through planning or Building Regulations requirements. And never appoint them as Contract Administrator or Principal Designer (Construction).

Also, ask yourself whether you really need them. You may end up paying for a drawing only for a registered architect to have to redraw it. That’s because it misses key planning rules, lacks technical detail, or can’t be built as drawn.
