A design-and-build interior package can simplify coordination, but ask for a costed scope before you let one provider design, buy and install everything.
Define the design deliverables
Ask whether the proposal includes a measured survey, layout, drawings, specifications, material selections and a budget estimate. Find out how many revisions are allowed and when you must approve the design. A visualisation is helpful, but it does not replace the information needed to price and execute the work.
Understand the build responsibilities
Identify the contractor and any subcontractors, and ask who is responsible for specialist work, permits, site safety and required inspections. Confirm the scope of construction, supply and installation. Where technical work requires qualified professionals, establish their roles and appointments before work starts.
Control changes in writing
Ask for separate figures for design, materials, labour, transport, project management and contingency, plus written exclusions. Agree who approves substitutions, how supplier invoices are shared, which workmanship warranty applies and who handles defects. Compare a design-and-build package with design-only and independent contractor quotes using the same drawings, and record payment milestones and changes in writing.
If the provider earns a sourcing fee or supplier commission, ask how it is calculated and recorded. Keep product allowances and approved selections visible so you can see what the package covers.
