Early feasibility
Explain what the additional space needs to achieve. Ask what must be assessed about the existing home and site before a design direction can be considered.
Design and approvals
Confirm who develops drawings and specifications, provides the required professional input and handles permissions. Understand the responsibilities and decisions at this stage.
A construction scope
A proposed construction package should connect the approved requirements with included work, exclusions and terms. Ask how changes and coordination will be handled before making an agreement.
