Describe what is changing
Explain the spaces involved, what is staying and what the change needs to achieve. General location and timing help the company understand the enquiry.
Ask about assessment
Confirm which drawings, surveys or other information are required. Appropriate professionals must establish the actual design, structural and regulatory requirements.
Review responsibilities
Understand design, permissions, related trades, exclusions and the proposed sequence. A written scope should clarify who is responsible before you agree to proceed.
