1. Separate needs from preferences
Explain what is not working in the current home and what you want the changed space to achieve. Identify the features you must retain.
2. Make the existing conditions visible
Note available plans and known building issues, access constraints or services. Project-specific investigation may be needed before the scope can be settled.
3. Plan around daily life
Discuss occupancy, access and timing constraints. Record what remains uncertain, who will investigate it and how design or site changes will be considered.
This is project preparation guidance. Site suitability, approvals and specialist requirements need project-specific assessment.
