The feasibility stage is the initial sketch design for the project. It involves defining the brief, making proposals in the form of renderings, watercolours or models in order to describe the project and producing a set of plans to a scale of 1:100.

In the case of large development projects a explanatory brochure is also normally produced to detail the ideas.

Together with the design an initial cost prediction will be provided so that the client can begin to understand how much the construction is likely to cost.

If required an overall project cost plan can also be produced showing the total project cost.
