No, you do not legally need an architect to apply for planning permission in the UK. You can prepare and submit a planning application yourself, provided you include the correct drawings, forms and supporting information. However, professional design support can make the process much easier, particularly if your project is complex, your property has planning restrictions, or you are unsure what your local planning authority will accept.
Is an Architect Legally Required for Planning Permission?
There is no general legal requirement to appoint an architect before submitting a planning application.
Homeowners can submit applications themselves or work with an architectural designer, technician, planning consultant, or another suitably experienced professional.
What matters is that the application is complete and accurate, and that it gives the local planning authority enough information to assess the proposed development properly.
For a simple project, such as a straightforward house extension, you may feel comfortable managing the process yourself. For larger or more complicated work, professional input can help reduce the risk of missing important information or submitting unclear drawings.
What Drawings Do You Need for Planning Permission?
The exact drawings required depend on your project and your local authority’s requirements. Most planning applications will usually need a location plan showing the site in relation to the surrounding area.
Depending on the type of development, you may also need:
- Existing and proposed floor plans
- Existing and proposed elevations
- A block or site plan
- Roof plans
- Section drawings
- Information about materials
- Details of boundaries and neighbouring properties
- Supporting statements or reports
All drawings should clearly show what currently exists and what you are proposing to change.
For example, if you are planning an extension, the planning authority will usually want to see its size, height, position and appearance in relation to the existing property and neighbouring homes.
Accurate drawings are important because planning officers rely on them when assessing whether a proposal is acceptable.
Do Planning Drawings Have to Be Prepared by an Architect?
No. Planning drawings do not have to be produced by a registered architect.
They can be prepared by an architectural designer or another professional with the appropriate experience. You can also prepare them yourself, though they will still need to meet your local authority’s standards.
Professional architectural design services can be useful where measurements, layouts or elevations need to be developed accurately.
Amico Design, for example, helps homeowners prepare architectural drawings, develop proposals and manage the information needed for planning applications.
What Information Is Usually Needed for a Planning Application?
In addition to drawings, most applications will require a completed planning application form and information about the property and proposed works.
Depending on your project, you may also need:
- Ownership certificates
- A Design and Access Statement
- Details of materials
- Heritage information
- Tree or ecological surveys
- Drainage information
- Parking or access details
- Other technical reports
The exact requirements vary depending on the location, property and scale of the development.
Your local council may also have its own validation checklist setting out the information it expects to receive.
When Can Professional Design Support Help?
Professional support can be particularly useful where a planning application is more involved.
For example, you may benefit from professional help if you are planning:
- A large or two-storey extension
- A new-build property
- Major remodelling
- A project in a conservation area
- Work to a listed building
- Development within the Green Belt
- A project on a difficult or restricted site
A designer can help turn an initial idea into a clear proposal before preparing the drawings needed for submission.
They can also help interpret planning feedback and make design changes if concerns are raised.
Amico Design supports homeowners with planning applications, including preparing drawings and proposals, and providing assistance throughout the submission process.
What Is the Difference Between Simple and Complex Projects?
Not every project requires the same level of professional input.
A small, straightforward extension may only require a limited set of drawings and supporting documents.
Some projects may even fall within permitted development rights, meaning full planning permission may not be required at all.
More complex developments can require considerably more information.
For example, a large extension, new home, or development affecting a listed property may require detailed design work, along with specialist reports or planning statements.
The more complex the proposal, the more important it becomes to clearly demonstrate how the development fits within its surroundings and complies with relevant planning policies.
Why Does Local Planning Knowledge Matter?
Planning policies can vary between different local authorities.
Although national planning rules provide the overall framework, councils also have their own Local Plans, design guidance and planning policies. That means a design that may be acceptable in one area may need to be approached differently somewhere else.
Local factors such as conservation areas, previous developments, surrounding properties and neighbourhood character may also influence how an application is assessed.
Working with professionals who understand the local planning process can therefore be useful.
For homeowners looking for architects in Northampton or architectural design support in the surrounding area, Amico Design can help develop proposals that meet local planning requirements.
Why Are Accurate Planning Drawings Important?
Planning drawings are one of the main ways a planning officer understands your proposal. They should clearly show dimensions, layouts, elevations and the relationship between the proposed development and the existing property.
If the drawings contain conflicting measurements or missing information, the council may request revisions before progressing the application. In some cases, an incomplete application may not be validated until the necessary information is supplied.
Accurate drawings help avoid unnecessary delays and make your proposal easier to assess.

Frequently Asked Questions
Do I need an architect to apply for planning permission?
No. You can submit your own planning application or appoint another suitable professional to help you.
Can I draw my own plans for planning permission?
Yes, although the plans will need to be accurate, drawn to an appropriate scale and include the information required by your local planning authority.
What drawings are usually needed?
Most applications require a location plan and may also require floor plans, elevations, site plans, roof plans, or sections, depending on the project.
Does every extension need planning permission?
No. Some extensions fall within permitted development rights. However, this depends on the property’s location, previous alterations and the size and design of the proposed extension.
Is planning permission the same as Building Regulations?
No. Planning permission considers whether a development is acceptable from a planning perspective. Building Regulations cover technical standards such as structure, fire safety and energy efficiency.
Do You Need Professional Help With Your Planning Application?
You do not need to appoint an architect simply because your project requires planning permission.
For smaller projects, you can manage the process yourself. For more complex proposals, professional design support can help ensure that your drawings are accurate, your application contains the right information, and your design responds to local planning requirements.
Amico Design can help homeowners develop proposals, prepare architectural drawings and navigate the planning application process from the early design stages through to submission.
