How Much Does An Architect Cost In Glasgow?

Updated: Jun 24

The cost of hiring an architect in Glasgow can vary wildly depending on several factors such as the scope and complexity of the project, the architect's experience and reputation, and the specific services required.


Traditionally, an architect’s fee for a ‘Full Architectural Service’ (from inception through to completion) is charged as a percentage of the construction cost (excluding VAT).  This is because the value of a project can be aligned with the likely time invested by the architect.


Up until 2003, the RIAS published ‘percentage fee scales’ for a wide range of projects (see extract below).  Based on the old fee scale, the percentage fee for a single storey house extension with a project value of £150,000 (excl. VAT) would be 13.5% = £20,250 

However, we find that a more cost-effective way of providing architectural services is to split the whole process into stages and you only pay for the services you want. In simple terms, the stages are:


  • Briefing, survey and preparation of existing drawings (measured survey is carried out by others)

  • Sketch design options (including 3D model)

  • Preparation of planning drawings and application

  • Preparation of detailed drawings and building warrant application

  • Construction Design Management (in a partial service our appointment would end here)

  • Construction documentation & tendering

  • On-site Involvement


After we have visited your home and carried out the initial consultation, we can provide a bespoke fee proposal tailored to your needs.  Our fee proposal will be based on how long we expect each stage to take based on our previous experience of similar projects.  Our fee for the initial design, planning and building warrant is offered as a fixed fee.  Our fees for construction documentation, tendering and contract administration is based on an hourly rate of £50 p/h (we do not charge VAT). 


Other Costs

As the lead consultant, we work alongside other construction professionals form the design team and can advise on the appointment of the Structural Engineer, Quantity Surveyor & Measured Building Surveyor. An Asbestos Survey may be required if the work involves alterations to an existing house. Also, there are local authority fees for planning and building warrant applications to pay.


For a more precise estimate, it's best to contact several architects in Glasgow, discuss your project requirements, and request detailed quotes. This will give you a clearer idea of the specific costs involved for your project.
