Architect Costs vs Other Architectural Professional Costs

If you've got a home renovation on the horizon, architect costs will likely form part of your budget, but the amount you pay depends heavily on whether you hire a registered architect or another qualified architectural professional, such as an architectural technologist or designer. Both can carry out much of the same work, but registered architects generally charge more, reflecting their ARB registration and broader design remit.

Architect 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 architect fees. Other architectural professionals typically charge 20 to 40% less for comparable work, which on that same build could mean paying somewhere in the region of £18,000 to £34,000.

Here's how architect costs compare to other architectural professional costs for a few common projects:

Registered architect costs:

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
Typical fee as % of construction cost	3% – 15%

Other architectural professional costs:

Service	Cost
Single-storey extension planning drawings only	£800 – £1,800
Full set of plans (planning + building regs drawings)	£1,800 – £3,800
New build planning application drawings	£2,800 – £3,600
Building regulations & tender drawings	£5,000 – £9,500
Typical fee as % of construction cost	2% – 10%

Note: VAT is typically added to these fees. Use these figures as a starting benchmark when comparing quotes, since exact pricing will always depend on your project's scope, region, and the individual professional's experience.

MyBuilder Tip: Whether you hire a registered architect or another architectural professional, if you're changing the walls or overall structure of your home, your project may also require a structural engineer. For a breakdown of structural engineer costs, check out our price guide.

Architectural Services and Their Costs

Architect costs, and other architectural professional costs, usually break down by the specific service or stage of work involved rather than one flat fee. Understanding what each stage covers makes it easier to see where your money is going and to spot what you can safely trim from a quote.

Here's a breakdown of typical architectural service costs:

Architectural Service	Typical Cost
Initial consultation or feasibility study	£150 – £1,500
Planning application drawings	£1,200 – £4,000
Building regulations drawings	£2,000 – £8,000
Construction and tender drawings	£3,000 – £12,000
Full project management & site visits	3% – 15% of construction cost (architect) or 2% – 10% (other architectural professional)

A closer look at what each service involves:

• Initial consultation or feasibility study: An early meeting or short study to assess whether your project idea is workable before committing to full drawings.
• 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.
• Project management & site visits: Ongoing oversight throughout the build, often billed as a percentage of the total construction cost.

Architectural drawings specifically, whether prepared by a registered architect or another architectural professional, are one of the most common costs homeowners budget for, ranging from £1,200 for basic planning application drawings to £12,000 or more for a full set including building regulations and tender drawings. Other architectural professionals generally come in toward the lower end of these ranges for the same service.

Don't forget: Discuss your specific needs with architectural professionals to determine which services are necessary for your project. If you have any initial questions or want to find an architect or architectural professional near you, you can simply post your job on MyBuilder. Include any questions or details about your project and architectural professionals will be in touch.

Hourly Rates: Architects vs Other Architectural Professionals

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

In the UK, registered architects typically charge between £50 and £100 per hour, while architectural designers and technologists typically charge between £40 and £80 per hour, reflecting their lower overheads and narrower design remit.

For small jobs, a fixed fee is common with either type of professional, 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 instead, as outlined above.

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

Beware of These Hidden Costs

When entering into an agreement with an architect or architectural professional, there are some hidden costs you should be aware of that can come up during the project, regardless of which type of professional you choose.

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 architectural professionals offer a free first consultation, so it is worth asking upfront.

When to Hire an Architect vs Another Architectural Professional

Since both can carry out much of the same work, the right choice usually comes down to the complexity and ambition of your project rather than cost alone.

A registered architect is likely the better fit if:

• Your project is architecturally complex, such as a large new build, a listed building, or an unusual site.
• Design and aesthetics are a priority, not just function and compliance.
• You want one professional to lead the concept, coordinate consultants, and oversee the build.

Another architectural professional, such as an architectural technologist or architectural designer, may be equally well-suited if:

• Your project is a straightforward extension, loft conversion, or planning drawing job.
• You mainly need technical drawings, building regulations compliance, or a planning application prepared.
• You're looking to keep costs down without compromising on the technical quality of the work.

Many homeowners find that other architectural professionals can deliver the same practical outcome for a lower fee on straightforward projects, while a registered architect earns their premium on larger or more design-led jobs.

Cost-Saving Tips for Hiring an Architect or Architectural Professional

Investing in an architect or architectural professional 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 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 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 architects and other architectural professionals offer better rates if you combine several parts of the job.

Consider smaller firms or independent architectural professionals

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

FAQ: Common Questions About Architectural Services Costs

What Factors Influence Architect Costs for a Home Addition?

Architect costs 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 architectural professional's experience and level of qualification can affect the cost.

What Should I Expect to Pay for an Initial Architect 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 architectural 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 architectural professional's approach fits your needs.

Do I Need Planning Permission for My Extension, and Can an Architect 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 type of architectural 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 technologists and designers typically charge 20 to 40% less than registered architects, making them a cost-effective choice for straightforward extensions and conversions.

Is "Architect" a Protected Title?

Yes. In the UK, "architect" is a legally protected title regulated by the Architects Registration Board (ARB). Only those registered with the ARB can use it. Architectural technologists, designers, and other architectural professionals are not registered architects, but many are qualified to carry out the same drawings, planning applications, and technical work for most residential projects.
