Fees are charged as a percentage of the project cost, usually in the range of 10-15% depending on the complexity and value of the work. Alternatively, if you're looking at a smaller project such as a drawing, design proposal or planning application, I have an hourly rate as per the Swiss Institute of Architecture (SIA) contract guidelines.
