Architect average costs
If you’ve got a home renovation on the horizon, hiring an architect might be the next step. Usually, architect fees range between 3% and 15% of the total construction cost, depending on how big your project is.
For example, on a £300,000 build, you might expect to pay between £30,000 and £42,000 in architect’s fees.
Here’s a quick look at the average cost of an architect for a few common projects:
| Service | Cost |
|---|---|
| Single-Storey extension drawings | £1,750 – £4,000 |
| Single-Storey extension building regs | £4,000 – £6,000 |
| New Build Planning application drawings | £4,000 |
| Building regulations & tender drawings | £7,000 – £12,000 |
Note: VAT is typically added to these fees.
MyBuilder Tip: In addition to an architect, if you are changing the walls or overall structure of your home, your project may require a structural engineer. For a breakdown of structural engineer costs, check out our price guide.
How much do architect drawings cost?
Architectural drawings play an important role in transforming your construction ideas into reality. They provide detailed insights for both your planning permission and building teams.
The average cost of architectural drawings can vary widely, influenced by factors like project complexity and area. Typically, these costs range from £1,750 for basic planning application drawings to £4,000 or more for more detailed projects.
Different types of drawings cater to varied project needs:
- Planning application drawings: For securing planning permission from local authorities.
- Building regulations drawings: To ensure compliance with safety and structural standards.
- Construction drawings: Provide detailed instructions for builders to execute the project.
- Tender drawings: Help contractors submit accurate and competitive bids.
Don't forget: Discuss your specific needs with your architect to determine which types of drawings are necessary for your project. If you have any initial questions or want to find architects near you, you can simply post your job on MyBuilder. Include any questions or details about your project and architects will be in touch.

What is an architect’s hourly rate?
When budgeting for your project, it’s helpful to understand that architects often charge hourly rates along with fixed or percentage-based fees.
In the UK, architects typically charge between £50 and £100 per hour, depending on their experience and the complexity of your project.
For small jobs, some architects prefer to offer fixed fees, such as £1,000 to £2,500 for a planning application or construction drawings. Larger projects, like full house extensions or new builds, often involve a percentage of the total construction cost, usually between 10% and 14%.
For bigger projects, like a new house or major renovations, fees could reach £20,000 or more. Always ask an architect for all the details about your job, including quotes and a timeline.

Beware of these hidden architect costs
When entering into an agreement with an architect, there are some hidden costs you should be aware of that can come up during the project.
Understanding these costs can help you manage your budget effectively and avoid surprises along the way:
Additional services: Be wary of additional services that may not be included in the initial fee proposal, such as project management or site visits. These can lead to extra costs.
Design revisions: Limitations on the number of design revisions included in the original fee can result in additional charges if exceeded. Discuss the scope of revisions beforehand.
Planning applications: Fees for planning applications and obtaining necessary permits may not be included in the architect's initial quote. Always verify what is covered.
Scope changes: Changes in project scope, such as modifying design plans or materials, can incur extra fees. Define the scope clearly at the outset to avoid this.
Consultation fees: Initial consultations might be offered free, but further meetings could come with a charge. Confirm the number of consultations included in the fee.
Cost-saving tips for hiring an architect
Hiring an architect can really boost the design and function of your project, whether you’re renovating, extending, or building new.
But don’t worry, there are a couple of ways to manage the costs without cutting corners on quality:
Ask for fixed fees: Try to agree on a clear total price upfront so there are no surprises.
Focus on what you need: Stick to the essential services to avoid paying extra for things you don’t.
Bundle services: Architects often offer better rates if you combine several parts of the job.
Consider smaller firms: Independent architects can be more affordable but still deliver great results.

FAQ Common questions about architect costs
What factors influence architect fees when planning a home addition?
Architect fees for a home addition depend on several elements, including the size and complexity of the extension, the existing state of your property, and how custom your design needs to be. Location also plays a role, as prices can vary by region. Additionally, planning permissions, zoning rules, and the architect’s experience and reputation can affect the cost.
What should I expect to pay for an architect's initial consultation?
Initial consultations with architects can range from free meetings to fixed fees or hourly rates, typically between £50 and £200. This first session is your chance to discuss your project’s goals, budget, and timeline, and to see if the architect’s style and approach fit your needs.
Do I need planning permission for my extension, can an architect help with this?
Planning permission is often required for extensions, especially if they exceed certain size limits or affect the appearance of your property. Architects can help you determine if your project needs permission and guide you through the application process
What is an architectural technologist and how do they differ from an architect?
An architectural technologist is a specialist who focuses on the technical side of building design and construction. They bridge the gap between the architect’s creative vision and the practical aspects of making buildings safe, functional, and compliant with regulations.
While architects concentrate on the overall design and aesthetics, architectural technologists handle detailed technical drawings, materials specifications, building regulations, and project coordination.

Lintel replacement on a semi detached house
Anonymous user 05/05/2026 - 8.08 AM
I'm hoping someone maybe able to give me some advice. My dad had a note put through his door from his next door neighbours which I've attached below. I'm just trying to get some knowledge before I respond back to them on the matter. Is this something typically that a semi detached house would split financially? As per the letter my dads neighbour have been having a lot of building work done recently so rightly or wrongly part of me is thinking was this caused as the work was done and they are trying to halve their bill. Either way any advice would be handy Thanks! CONTENT OF LETTER: "We recently had some building work done at our home and during that process it was pointed out that the lintel running across both of our garages has cracked on our side. We've had a couple of builders take a look and the advice is that it should be replaced. As it's a shared/party structure it's likely the whole lintel would need to be done at the same time. We wanted to let you know and see whether you might be happy to pop over at some point so we can have a quick look together and chat through what's involved and the best way to approach it. As it's a shared structure we'd also like to discuss whether we might look at the cost jointly - but absolutely no pressure. We just want to make sure we handle it properly and keep things straightforward for both sides. Do let us know when might suit you"
