Percentage-Based Architectural Fees
Architectural fees can be based on a percentage of the cost of the building. The reason for relating the architectural fee to building costs is that the factors affecting the cost to build also affect the time required to design.
A large and complex project will naturally take longer to design and cost more to build than a small and simple one.
One advantage of the percentage fee type is its flexibility. If the scope of the project increases or decreases, the overall fee can change accordingly without having to renegotiate.
