New wishes or unexpected conditions can arise during renovation. Record their effect on cost and time before proceeding.
Compare the complete intervention
Request both direct costs and temporary provisions for each phase. Include additional removal and reinstatement when phasing otherwise appears cheaper than one coordinated intervention.
Describe the change
State what differs from the agreed scope and why. Use a drawing or photograph where helpful.
Consider all consequences
An added connection can affect pipework and finishes. Discuss delivery, sequencing and any work that is no longer required.
Decide this before construction
Address assessed causes of defects before new finishes conceal them. Plan comfort measures together with ventilation and necessary access to building services.
How to review the result
Check both completed work and preparations for the next phase. Record which connections are deliberately temporary and when they will be reassessed.
A situation to test your plan against
Combining maintenance and comfort improvements should avoid reopening new finishes later. List known defects, desired improvements and items still needing investigation together. Not every item needs the same phase.
