Grey Structure vs Turnkey: Which Contract Suits Your House?

Two building quotations may appear similar while describing entirely different obligations. Grey structure normally concentrates on structural and masonry elements, while turnkey extends through a specified finishing level. Neither term has a guaranteed universal definition; the signed schedule of works is what counts.

What is commonly included in grey structure?

Depending on the contractor, excavation, foundations, RCC elements, masonry, roofing, plaster and selected concealed service points may appear in the schedule. Waterproofing, boundary walls, electrical wiring or plumbing may be included, partly included or excluded. Demand an itemised breakdown.

What does turnkey add?

A complete package can include tiles, woodwork, paint, kitchen, bathrooms, lighting, electrical accessories, plumbing fixtures, ceiling works and external development. Finish quality has an enormous effect on cost, so specify products, grade, quantities and allowances.

Which option offers more owner control?

A grey-structure-first approach may let an owner choose finishing contractors later, but it places greater coordination responsibility on the owner. Turnkey may simplify management but requires a strong written agreement to avoid disputes over ambiguous finish specifications.

How should you compare quotations?

Match structural design assumptions, work quantities, steel and concrete specifications, MEP inclusions, waterproofing scope, labour responsibility, transport, tax, wastage, payment schedule, defects and handover requirements. Consider whether delays between contractors could increase the overall cost.

Contract checklist

Attach signed drawings, BOQ, finish schedule, milestones, variation rates or process, dispute procedure, supervision responsibilities, retention or defect terms where applicable, and a clear record of owner-supplied materials.

FAQs

Can I hire one team for grey structure and another for finishing?

Is turnkey a fixed-price guarantee?
Only the terms of a written, properly scoped contract determine whether prices are fixed or adjustable.
