The architect will analyse your requirements further and will present developed proposals in the form of drawings for you to evaluate. Drawings can be difficult to understand, but it is vital that you work with your architect to fully understand the proposals, before applying for any planning permission and before starting to build. If you have any doubts, raise them with your architect at the time so that you fully understand and agree about what is to be built. This is important, because once a project goes on site, changes can be expensive, can delay the project, and may even require an additional planning permission. Project cost and timescale should be re-evaluated and agreed at this stage.
