Do I Need an Architect or an Architectural Designer in the UK?
If you are planning a house extension, loft conversion, or renovation, you may wonder whether you need to hire an architect or whether an architectural designer can provide the services you need.
Many homeowners assume an architect is required to submit planning drawings. In reality, most residential planning applications in the UK are prepared by architectural designers or technicians.
Understanding the difference between the two can help you choose the right professional for your project.
What Is an Architect?
An architect is a professional who has completed formal architectural education and is registered with the Architects Registration Board (ARB).
In the UK, the title “architect” is legally protected. Only individuals registered with the ARB are allowed to use it.
Architects often work on large or complex projects such as new-build houses, commercial buildings, and major developments.

What Is an Architectural Designer?
An architectural designer provides architectural design and drawing services but is not registered with the Architects Registration Board.
Many architectural designers specialise in residential work, particularly house extensions, loft conversions, and internal alterations.
Typical services provided by architectural designers include measured surveys, planning drawings, planning applications, and building regulations drawings.
Because they often specialise in residential projects, architectural designers can sometimes provide the same practical services needed for planning permission at a more affordable cost.
Do You Need an Architect for Planning Permission?
No. Planning drawings do not legally need to be prepared by an architect.
Local authorities simply require accurate drawings that clearly show the proposed development. These drawings can be prepared by any competent professional with experience in residential design.
For many homeowners planning an extension or loft conversion, an architectural designer can provide all the drawings required for the planning application.

Projects Where an Architectural Designer Is Often Suitable
Architectural designers frequently work on typical residential projects such as rear extensions, side extensions, loft conversions, garage conversions, and internal alterations.
These types of projects usually require planning drawings followed by building regulations drawings after planning approval has been granted.
Professionals who regularly work on residential planning applications often develop a strong understanding of planning policies and design constraints.
When an Architect May Be the Better Choice
There are situations where hiring an architect may be beneficial.
For example, complex architectural projects that require extensive design exploration may benefit from the broader design services that architects provide.
Architects may also be involved in large new-build homes, commercial developments, or projects where full construction-stage services are required.
Experience Matters More Than Job Title
When choosing someone to prepare planning drawings, experience with your type of project is usually more important than the professional title.
Someone who regularly prepares drawings for residential extensions will typically understand planning requirements, council expectations, and the technical details needed to obtain approval.

Final Thoughts
For most residential projects in the UK, homeowners do not necessarily need an architect.
Architectural designers frequently prepare the drawings required for planning permission and building regulations, particularly for extensions and renovations.
Choosing a professional with experience in residential planning applications can help ensure the process runs smoothly and that your project progresses efficiently.
