The three common fee structures

  1. 01

    Fixed fee

    A single price for a clearly defined scope — for example, concept through detailed design for a defined number of rooms. Best when the scope is genuinely clear, and the most predictable for the client.

  2. 02

    Rate per square metre

    Common on villas and larger projects, where area is the fairest measure of work. Ask what level of detail the rate assumes, because a shell layout and a fully detailed joinery package are very different amounts of drawing.

  3. 03

    Percentage of construction value

    Traditional on architectural projects. It scales with the build, which aligns the designer with quality rather than cost-cutting, but it needs a realistic construction budget from the start to be meaningful.

What actually moves the number

  • Area, and how many distinct rooms need designing
  • How many stages you need — concept only, or through to site coordination
  • Level of detail: standard joinery versus fully bespoke millwork
  • Whether FF&E procurement and styling are included
  • Renovation versus new build, and how much surveying the existing structure needs
  • Approvals: developer, community or authority submissions add coordination
  • Visualisation: how many renders and design options you want to see

Design fee is not project cost

The design fee is usually a small fraction of what you will spend. The larger numbers are construction, joinery, stone, lighting and furniture — which is precisely why design is worth resolving properly before anyone starts buying.

A realistic budget conversation at the first meeting protects you. A designer who knows your range can steer material choices that hold the design together instead of specifying a scheme you will later have to strip back.

Questions worth asking before you sign

  • What exactly is included at each stage, and what is extra?
  • How many rounds of revision are covered?
  • Who specifies and who procures the furniture?
  • Is site coordination included, and how often?
  • What happens to the fee if the scope grows?
