Project delivery

Design-only vs. design-build: where responsibility changes

Understand which decisions stay with the architect, which move to the builder, and where coordination risk can enter the project.

Both delivery paths can produce an excellent home. The difference is where decisions live — and what happens when design and construction information has to cross a contract boundary.

Design-only

The architect owns the brief, concept, technical documents, and approvals support. The client appoints a builder, typically through bidding or negotiation.

The strength of this path is choice: the client can select a builder on price, availability, or relationships. The risk is coordination — constructability, costing, and site decisions must be translated across two teams, and design intent can be diluted at each handoff.

Design-build

One architect-led team carries the project from brief to turnover. Constructability and cost enter the conversation during design, not after it.

The client holds one accountable path: one communication channel, one baseline budget, and one team responsible for resolving the gap between drawings and the finished home.

A practical test

Ask where you want to spend your attention. If you want to manage separate contracts and compare builders directly, design-only may fit. If you want a single accountable team and earlier cost certainty, design-build is usually the better fit.
