Hire an architect separately when the project is architecturally ambitious, unusual, or historically sensitive and the design itself is the point. Choose design-build when the goal is a well-executed addition or remodel delivered on a known budget and schedule — which describes most residential projects.
The two models, side by side
| Design-Build | Architect + Contractor | |
|---|---|---|
| Contracts you sign | One | Two, sometimes three |
| When the real price is known | During design | After design, at bid |
| Typical time to break ground | 4–10 weeks | 3–6 months |
| Design fee | Inside the construction contract | Separate, often 8–15% of construction |
| Who resolves a plan conflict | One party | Negotiated between two |
| Design ambition | Practical, builder-informed | Can go further |
The case for hiring an architect separately
An architect working independently is not accountable to a construction budget, and for certain projects that independence is exactly what you want. Choose this route when:
- The project is architecturally ambitious — a significant whole-house reimagining, a difficult site, a strong design vision.
- The home is historically significant or in a district with design review, where documentation and advocacy matter.
- You want a true competitive bid from multiple builders on identical drawings.
- You value having someone whose only obligation is to the design and to you, administering the construction contract on your behalf.
The case for design-build
The structural advantage is that cost feedback arrives while decisions are still cheap to change. In the split model, the price becomes real only after a complete design set is paid for — and when the bids come back high, the reconciliation happens by deletion. Things that made the design good get cut, and you pay for the redesign.
The second advantage is conflict resolution. Every project produces moments where the drawing and the building disagree — a wall that is load-bearing, a duct where a soffit was drawn, a slab that will not take a drain where it was shown. With one company, that is a decision. With two, it is a meeting, a redesign fee, and a schedule delay while responsibility is assigned.
The middle path
You can hire an architect for schematic design — the concept, the massing, the floor plan — and then bring a design-build contractor in to carry it through construction documents, engineering, permitting, and building. You get the architect’s design thinking on the part where it matters most, and single-party accountability on the part where accountability matters most.
Birdseye works this way regularly, and it is often the right answer on a larger addition where the homeowner has a strong architectural preference.
How to decide
Ask what the project is really about. If it is about the design — you want something distinctive and you are willing to spend time and fee to get it — hire an architect. If it is about the outcome — a kitchen that works, an addition that fits the house, done on a known number by a known date — design-build gets you there faster and with fewer parties.

Frequently Asked Questions
Is design-build cheaper than hiring an architect?
Usually, for two reasons: there is no separate design fee on top of construction, and you are not paying to redesign a project after over-budget bids. On architecturally ambitious work the separate architect may still be the right spend.
Do you need an architect for a home addition?
In Texas, most residential additions need permit-ready drawings and an engineer’s stamp on the structural work, not necessarily a licensed architect. Complex or historically sensitive projects benefit from one regardless of what is required.
Can I hire an architect and still use a design-build contractor?
Yes, and it is a common hybrid. The architect handles schematic design and you bring the contractor in for construction documents, engineering, permitting, and building — keeping the design vision and the single point of accountability.
How do I get competitive bids with design-build?
You compare design-build firms against one another on scope, contract terms, references, and completed work rather than comparing identical drawings. The comparison is of companies, not of line items on one plan set.
Who pulls the permits in each model?
The contractor pulls construction permits in both models. In design-build the same company also produced the drawings, so questions during plan review go to one party rather than being relayed between the architect and the builder.
