Quick answer: A turnkey interior contract should include the full scope, the signed BOQ, a fixed handover date, a milestone-based payment schedule, a process for changes, who bears the risk of material loss on site, and a written warranty stating what's covered and for how long. If any of these is missing, ask for it before you sign.
Why the paperwork matters
When a project goes well, nobody reads the contract. When something goes wrong, it's the only thing that matters. Five minutes of reading now saves months of arguments later.
The contract checklist
- Scope of work — every room and every item, with a clear list of exclusions.
- Signed BOQ — attached to the agreement, with brands, grades and sizes.
- Approved 3D and drawings — referenced as the design to be built.
- Handover date — an actual date, plus what happens if it's missed.
- Payment schedule — tied to work milestones.
- Change process — how changes are priced, approved and timed.
- Site risk — who pays if materials are stolen or damaged on site. With COZ Turnkey Solutions, that's on us.
- Fair responsibilities — what the client is responsible for (timely payments, decisions, site access) so delays are judged fairly.
- Warranty — coverage, duration and how to claim.
What a good warranty looks like
A warranty should say what's covered (carpentry, hardware, finishes, installation), for how long, and what isn't covered (misuse, water damage from building leaks, normal wear). It should also tell you who to call.
At COZ Design Studio, warranty length depends on the package you choose, because better materials genuinely last longer:
- Essential — minimum 3 years
- Signature — 5–6 years
- Bespoke — 8–10 years
- Luxe — 15 years
After handover: COZ Shield
Small things come up in the first year as a home settles — a hinge needs adjusting, a drawer needs aligning. COZ Shield covers one year of maintenance after handover, with roughly 15–20 service visits.
FAQ
What warranty should an interior designer give? A written warranty covering carpentry, hardware and installation, with a clear duration and claim process. At COZ, it ranges from 3 to 15 years depending on the package.
Should the BOQ be part of the interior contract? Yes. The signed BOQ should be attached so materials and brands are legally part of what you're buying.
