Is design and build cheaper than traditional contracting?

The contract sum is often marginally higher because design risk is priced in. Final outturn cost is usually lower, because variations arising from design-to-site clashes sit with the contractor rather than with you.

Can I appoint my own designer and still use a design and build contractor?

Yes, this is novation. Your designer develops the concept, then the appointment is transferred to the contractor, who takes on the design obligation from that point. It is common on prime Dubai residential work.

Which route is faster?

Design and build, typically by two to three months on a large villa, because procurement of long-lead packages overlaps design and there is no separate tender period.

How do I keep quality honest under design and build?

A specification schedule naming actual products, a contractual bar on substitution without written approval, and an independent client-side reviewer checking valuations and compliance monthly.
