Future Ready Branch white paper: Design for the technology dependent

Provide exceptional design build service to our clients through the daily hands-on project involvement of our partners.

PhaseOne's designs for buildings are distinct, creative, and efficient. It was very comfortable knowing that PhaseOne was our architect and builder. Utilizing PhaseOne gave our Credit Union time to focus on our business serving our members and not concerning ourselves with building issues. I would, without hesitation, recommend PhaseOne Design Builders for any project."



PhaseOne's experience enabled us to maximize the use of our site, gave us an award winning design, and a well-constructed building that met our needs. PhaseOne was an invaluable partner in our project.


We hired PhaseOne because their Architects and Construction managers understood the need for complete rebranding of an old shopping Center located on an outstanding site. PhaseOne assumed the role of the Owner and made sure that the project phasing allowed the existing tenants to operate while the remodeling of the Center was underway. I would recommend PhaseOne to design and build any project.
