Can GB discuss a Hampshire project before all suppliers are chosen?
Yes, explain the intended work and identify the decisions still open. The conversation can establish information needed from designers or suppliers. A complete construction agreement should then reflect the resolved specification and responsibilities rather than leaving key components undefined.
Is floor area enough to compare extension prices?
No. Existing conditions and construction or finish specifications can differ materially. Use the full written scope as the basis of comparison.
What should be clear about work by other specialists?
Identify the specialist’s design, supply, installation and handover responsibilities separately. The building scope should record the information required from them, the stage at which access is needed and any making good outside their package. Keep current specifications available to all relevant parties. Separate appointments can work, but necessary connections should have an agreed owner rather than each contractor assuming another will complete them.
What completion information should I expect for an extension?
Agree the required handover records for the actual work, including relevant approvals or completion documents, specialist certificates, product instructions and the final scope of agreed changes. Walk through the work and record any outstanding items and their arrangements. Keep the documents together for maintenance, future alterations and any later property transaction. The precise records depend on the project, so identify responsibilities before construction starts.
