Tradesmen Costs for an Architect

In this section, we will look at the labour costs for hiring an architect, which are the costs without any supplies or materials.

House Design Planning

Architects can charge for their work in different ways. You may expect an architect to charge you in any of the following methods:

A Fixed Fee

The architect may charge you a lump sum for the work depending on how much work is involved for them.

A Percentage of the Project's Overall Cost

These percentages can range from 1.5%-20%. Larger projects will usually incur a lower-end percentage fee.

An Hourly Rate

The architect may charge a fixed hourly rate for their work.

Below is an example of what architects may charge for various stages of a project:

Planning Drawings for Planning Applications

This will cost around £3000-£5000. The price you pay will depend on the type and size of the project.

Draw Up Building Regulations and Tender Drawings

This will cost around £5000-£8000. The price you pay will depend on the type and size of the project.

Charges for the Full Service

This will include everything from conception to project completion. These prices will usually range from around 10% to 15%, depending on the size and type of project.

Below is an example of what you can expect to pay an architect for various jobs:

Architect Fees for an Extension

Drawings for building regulations and drawing up the build for the contractors will usually cost around £7500-£10,000. However, this will depend on the size and type of extension you're looking for.

If your architect is taking care of project management, you can expect to pay a percentage of the overall cost of the work for this. You can expect to pay around £17,500-£21,000 for the architect fees on an extension from start to finish.

Architect Fees for Loft Conversion

For a loft conversion, the architect fees will depend mostly on the size of the conversion. If you can complete the conversion without planning permission, this will reduce the cost.

If you do need planning permission, this will cost around £2500-£3500 for the architect fees. Plus, an extra £3750-£4500 to get the project ready to build. If the architect is the project manager, this will cost around £10,250-£11,000+.

Benefits of Hiring an Architect

There are many benefits to hiring an architect when it comes to structural work on your home. Below is a list of the main advantages of hiring an architect for this type of work:

Avoid Design Errors

If you choose not to seek professional construction advice, you run the risk of design errors coming into play that may only be noticeable once the construction is complete. This will end up costing you much more to fix and will also mean that the work takes much longer to complete.

Architects have the skills needed to ensure that your designs are safe, secure, and correct. This means that you will have peace of mind that your construction will be structurally sound and accurate once it's built.

Creative Solutions

No matter how large or small the project is, you don't want to end up spending more than your budget. Unfortunately, you may end up spending more money than you need to if the design plan is not drawn with a sharp eye and with the right knowledge.

Architects will have the knowledge needed to develop creative solutions and alternatives to help you stick to your budget and spend as little as possible. They may also suggest features that you hadn't even thought of.

Visual Aid

With advancements in technology, many architects have various ways of creating your project's construction plans. This can include videos, highly detailed drawings, and 3D plans to give you a clear idea of the design. This allows you to visualise the end result before the construction starts easily.

Visual Design Aids

Not only is this helpful so that you can see what the project will look like when it’s finished, but it also gives you the opportunity to see the areas that you don’t like so that changes can be made accordingly.


Q: How much does it cost to get architect drawings?

A: The cost for hiring an architect to draw up planning drawings for planning applications is around £3000-£5000, depending on the size of the project.

The cost for hiring an architect to draw up tender and building regulations drawings is around £5000-£8000, depending on the size of the project. The charges for an architect's full service are approximately 10-15% of the project's overall cost on average.

Q: How long does it take for an architect to draw up plans?

A: It will take around four weeks for the architect to draw up all of the plans for smaller projects. Larger projects may take considerably longer than that.

Ultimately, it depends on the type of project, the size of the project, and its complexity. Your architect should be able to give you an estimate on timescales during the first meeting.

Q: At what point in the project should I involve an architect?

A: As soon as you decide that you're going to invest in a project for your home, it would be best if you started looking for an architect. An architect can provide important pre-design services for your project, such as site evaluations.

They can also help you explore options you may not have already thought about. Involving an architect early can help you avoid costly mistakes and increase the likelihood of you being completely satisfied with the end result.

Q: What is involved with the initial design process?

A: Once your architect has had an initial meeting with you, they will liaise with you to ensure you are completely satisfied with the designs. They will assess your ideas, explore the use and layout of the building, and confirm your expected budget and construction timescales.

Q: Can I request changes if I don’t like the designs?

A: Most architecture firms will offer some revisions to their plans as part of the service. However, it is important to remember that this can add additional time to the job and could result in the entire project taking much longer.

As such, it's better to ensure you give your architect as much information as possible, to begin with, and work with them to ensure you're getting exactly what you want from the outset.
