New wishes or unexpected conditions can arise during renovation. Record their effect on cost and time before proceeding.
Compare the complete intervention
Identify coordination, protection and temporary provisions in the budget. Ask which party finishes each interface to avoid gaps between work packages.
Describe the change
State what differs from the agreed scope and why. Use a drawing or photograph where helpful.
Decide this before construction
Use release points between work sections: design complete, substrate assessed, concealed work recorded and finishes ready. The next party starts from an agreed condition.
How to review the result
Review each building section and then the whole home. Check transitions, operation and documentation; supplier completion lists do not automatically cover every shared interface.
Questions for your own property
