Is there a standard contract I can use with my designer?

When you have selected your designer, it is important to define the terms of the appointment with a signed agreement. Your designer might have a standard letter that they use, or you can use a ‘Standard Form of Appointment’. The RIBA (Royal Institute of British Architects) publish and sell a good selection of Standard Forms of Appointment for Architects, Interior Designers (BIID) and Landscape Designers (Landscape Institute).
