Our Team

Our success over the past 25 years has come from...


  • Our people. A close group of architects and designers who work as a team to design spaces from the inside out and the outside in. Having our architects and interior designers working so closely, enhances the outcomes of our projects and differentiates Phase 2 from other firms.

  • Our ability to truly listen and understand our clients' wishes, while at the same time engaging them with our vision for their project.

  • Our ability to apply attentive programming and comprehensive problem solving to achieve the the perfect design solution.


Our projects include designing entire homes and small commercial buildings, as well as renovating kitchens, family rooms and bathrooms. Regardless of the project, we strive to design spaces that are aesthetically pleasing and functional and have excellent circulation and flow. Our designs are heavily influenced by views, focal points, solar orientation, energy efficiency and sustainability.

Our team also provides interior design services for existing spaces. Frequently our vision includes modifications to the space. Even subtle changes, such as, adding windows to flank a fireplace or widening a doorway, can be transformative!
