New wishes or unexpected conditions can arise during renovation. Record their effect on cost and time before proceeding.
Compare the complete intervention
Compare quotations by room and by trade. Check that interfaces such as making good walls after service work are included exactly once, with clear responsibility.
Describe the change
State what differs from the agreed scope and why. Use a drawing or photograph where helpful.
Decide this before construction
Prioritise decisions affecting several rooms before individual product choices. Then use room-by-room decision dates linked to the work that would otherwise wait.
How to review the result
Use the room book as a handover checklist. Review transitions first and individual products afterwards; a fully supplied room can still have a missing junction.
Questions for your own property
