Average Costs of Architectural Services

If you've got a home renovation on the horizon, the cost of architectural services will likely form part of your budget. Whether you work with a registered architect or another qualified architectural professional, fees typically range between 3% and 15% of the total construction cost, depending on the size and complexity of your project.

For example, on a £300,000 build, you might expect to pay between £30,000 and £42,000 in architectural service fees.

Here's a quick look at the average cost of architectural services for a few common projects:

Service	Cost
Single-storey extension planning drawings only	£1,200 – £2,500
Full set of plans (planning + building regs drawings)	£2,500 – £5,000
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 architectural services, 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 Architectural Drawings Cost?

The cost of architectural drawings is one of the most common questions homeowners have when planning a project. Architectural drawings play an important role in transforming your construction ideas into reality, providing detailed insights for both your planning permission and building teams.

The cost of architectural plans can vary widely, influenced by factors like project complexity and area. Typically, architectural drawing costs range from £1,200 for basic planning application drawings to £5,000 or more for a full set of plans including building regulations drawings.

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 architectural professional to determine which types of drawings are necessary for your project. If you have any initial questions or want to find architectural professionals near you, you can simply post your job on MyBuilder.

What Is the Hourly Rate for Architectural Services?

When budgeting for your project, it's helpful to understand that architects and architectural professionals often charge hourly rates along with fixed or percentage-based fees.

In the UK, architectural services typically cost between £50 and £100 per hour for a registered architect, and £40 and £80 per hour for an architectural designer or technologist.

For small jobs, a fixed fee is common, 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, the cost of architectural services could reach £20,000 or more.

Always ask your architectural professional for all the details about your job, including quotes and a timeline.

Beware of These Hidden Architectural Service Costs

When entering into an agreement for architectural services, 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 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 can range from £150 to £500 for a basic meeting, with more detailed feasibility studies costing between £500 and £1,500. Some professionals offer a free first consultation, so it is worth asking upfront.

Cost-Saving Tips for Architectural Services

Investing in architectural services 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

Most homeowners do not need a full end-to-end architectural service. Many opt for a full set of plans and then manage the build themselves with a recommended builder, which can significantly reduce costs.

Bundle services

Many architectural professionals offer better rates if you combine several parts of the job.

Match the professional to the project

A registered architect may be the right choice for complex or design-led projects, while an architectural technologist or designer may be equally well-suited and typically 20–40% more cost-effective for straightforward extensions or planning drawings.

Consider smaller firms or independent professionals

Smaller practices and independent architectural professionals can be more affordable but still deliver great results.

FAQ: Common Questions About Architectural Services Costs

What Factors Influence the Cost of Architectural Services for a Home Addition?

The cost of architectural services for a home addition depends 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 professional's experience and level of qualification can affect the cost.

What Should I Expect to Pay for an Initial Architectural Consultation?

Initial consultations typically range from £150 to £500 for a basic meeting, with more detailed feasibility studies costing between £500 and £1,500. Some professionals offer a free first consultation. This first session is your chance to discuss your project's goals, budget, and timeline, and to see if the professional's approach fits your needs.

Do I Need Planning Permission for My Extension, and Can an Architectural Professional Help?

Planning permission is often required for extensions, especially if they exceed certain size limits or affect the appearance of your property. Both registered architects and other architectural professionals 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?

For many home projects, either professional may be equally well-suited; the right choice depends on the complexity and design ambition of your project.

• 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.

• A registered architect holds a protected title regulated by the Architects Registration Board (ARB) and typically leads on overall design concept and aesthetics, as well as project oversight. By contrast, architectural technologists handle detailed technical drawings, materials specifications, building regulations, and project coordination.

It is worth noting that architectural designers and technologists typically charge 20–40% less than registered architects, making them a cost-effective choice for straightforward extensions and conversions.
