You need to explain to the other party how you want to live on the specific property, or at least how you imagine it for the time being. There is hardly ever too much information. Desirable are:
- Information about the property, e.g. cadastral extract, development plan, information about existing / future neighboring buildings. (If something is missing, the architect can sometimes obtain it, or he / she will say what else is required.)
- Your room program: which rooms you want to live in, how large they should be, what relationship the rooms should have to each other (open kitchen, what on which floor), possibly also already which view you would like to have from where
- Your thoughts on the exterior design of the building, or the preferred style
- Requirements, no-gos, budget expectations
At the beginning, however, much is still in flux. During the first discussions, a site visit on the property, and throughout the phases in which designs are created and plans drawn, wishes will become more concrete or change, also through mutual exchange of information, which makes the whole process all the more exciting.
