Using an architect: from Conception to Completion

The engagement between architect and client should be a positive and productive experience. A good working relationship is very important to ensure a successful project. It is not necessary for clients to understand the technicalities of the work, but before proceeding with a project we will agree in detail exactly what it is that you are engaging Patrice Belle to do. This will be set out in our contract of engagement.

The RIBA divides projects into Work Stages A-M: from conception to completion. These are recognised throughout the UK construction industry (French project stages here). In the agreed terms of engagement we will clearly identify the work stages of the project for which you wish us to be responsible. Any subsequent variations will be agreed in writing.
