An architect's fee is normally based on a percentage fee of the construction cost of the project. The construction cost is outlined in the architect's Condition of Appointment, and includes all construction work with a few exceptions. This is not the same as the total budget cost, which includes consultant fees, statutory fees and service provider costs.


There is a sliding scale chart from our professional body the RIAS which Dualchas uses which fixes a percentage fee against the construction cost. There are different sliding scales for different project types, which reflects varying complexity. We will establish a realistic budget cost for the construction of the build at the start of the process so as to calculate this fee.


For more information about appointing an architect please read: 'Why use a Chartered Architect?',  and 'Architect's fees'


There will be other consultants required for the process. This may include:


  • Topographical surveyor
  • Drainage Specialist
  • Structural engineer
  • Mechanical and Electrical Engineer
  • Quantity Surveyor


At the start of the project, we will let you know which of the consultants are required, and what the likely costs will be. Note that VAT of 20% is due on consultant fees, but VAT is not applicable to new-build construction costs.


Work Stages


Project fees for the work of an architect are broken up in to work stages.

Stage C (Outline proposals) - 15%

Stage D (Detailed proposals) - 20%

Stage E ( Final proposals) - 40%

Stage F/G (Tender) - 10%

Stage H/L (Building contract) - 15%


Stages A/B relate to feasibility of the project. This is not always required and is often charged on an agreed lump sum basis.


Our contract will lay out all the services included within our fee schedule. It will also set out the architect's and client's responsibilities. A sample contract can be viewed here.
