Commercial Projects

The division between work and home has been dissolving slowly over the past two decades with advances in technology and has been significantly hastened in the post-COVID environment.

We check emails and work at all hours of the day, have telehealth visits with doctors and attend virtual parent/teacher conferences.

Workers are asking questions of their built environment and demanding more from them in terms of use, comfort and privacy. We will explore all these opportunities with you and guide you through a thoughtful design process that creates supportive and inspiring spaces.

Our Proven Design Process



The process begins with spending time with our team where together we assemble inspiration images, conduct lifestyle interviews, define the premise of the project, and ultimately, discover a path to completion.



Our team will explore residential design solutions using 2D sketching, 3D modeling, and BIM technologies to develop a thoughtful and suitable scheme.



We collaborate with a group of engineers specialized in residential architecture to develop the construction documents necessary for permitting and construction. We make sure all the details and coordination proceed in a timely manner, and maintain the architectural and design integrity of the project.



We are partnering with the best construction experts in the area. We help you to choose a professional contractor and ensure a good working relationship.


Building permits

We are able to efficiently navigate the complex permitting process to get the project off the ground.
