The main difference is contract structure and workflow. In the traditional design-bid-build model, you hire an architect to create plans, then bid those plans to separate general contractors — two contracts, two teams. In a design-build approach, a single company handles both design and construction under one unified contract, keeping designers and builders collaborating from day one.

It depends on scope and priorities. If you're building a highly complex, architecturally unique home where independent design advocacy is your top priority, an independent architect is often the right fit. If you want a streamlined process, faster project delivery, and a single point of accountability where design and construction are managed under one team, a design-build firm like Kellogg Construction is typically more efficient.

The two main trade-offs of design-build are reduced pricing transparency — since projects aren't put out to open competitive bid among multiple contractors — and less design independence, since design choices are often weighed against construction efficiency and the firm's building capabilities. For most residential projects, the trade-off is worth it: single-team accountability, faster delivery, and built-in budget alignment. For highly experimental or one-of-a-kind architectural visions, the traditional architect route may serve better.

No. "Architect" is a legally protected professional designation requiring specific degrees, extensive internships, and state licensing exams. Architects are typically required for large-scale, structurally complex, or multi-story residential and commercial projects. Building designers often focus on residential remodels and standard single-family homes where the scope doesn't require full architectural licensure. Kellogg Construction coordinates with licensed architects and structural engineers whenever a project requires them.

Every Kellogg design-build project follows three phases. First, a consultation where we understand your goals, walk through the space, and align on scope, timeline, and budget. Second, concept and estimate — we develop layouts, material specs, and finish selections, then deliver a transparent estimate rooted in real construction costs. Third, build and deliver — our team executes the project with weekly progress updates and quality inspections through to the final walkthrough.
