Every commercial project is unique — whether you're creating a new office, retail unit, restaurant, or mixed-use space, your architect helps ensure it's functional, compliant, and cost-effective. Below is a simple guide to how fees typically work and what's included at each stage.
How Architects Usually Charge for Commercial Work
Commercial projects can vary widely in size and complexity, so fees are usually calculated in one of three ways:
- 1.Percentage of the total construction cost — typically 6–10% depending on project scale and service level.
- 2.Fixed fee per stage — agreed once the scope and budget are clear.
- 3.Hourly rate or day rate — used for smaller projects or feasibility-only studies.
Additional consultants such as structural engineers, mechanical & electrical (M&E) designers, and building control specialists are appointed separately.

Tips for Commercial Clients
- •Clarify your business needs early — number of staff, customer flow, or equipment requirements shape the design.
- •Allow time for statutory approvals — change of use and fire compliance can add weeks.
- •Invest in early feasibility studies — they prevent costly surprises later.
- •Use an architect-led tender process to ensure accurate and competitive quotes.
- •Maintain design oversight during construction — it safeguards quality and compliance.
