Our Design Process

How we create.


The reason why a project can exist in the first place is because of the client. Getting to know our clients on a personal level along with understanding the project site and program is a key part of the discovery process. This information gathering is critical to help us get aligned with our client and establish a strong foundation for the next phase.


Taking all the information that was gathered from the discovery process, we then begin to synthesize that data to form it into a design concept that is in line with the initial goals vocalized by our client. The process is a very schematic in its nature to allow for both client and architect to discover what can be the best solution that matches the client's stated goals. This is where the building's form, orientation, site plan layout, spatial adjacencies, and materiality are decided upon.


After an overall concept is created that fits our client's program, we move into documenting the building design. At this stage our office works to create the construction documents that are used to build the project and get it through the different permitting and building code reviews.


Once a contractor is decided upon and a ground breaking date is set, our office transitions to providing construction observations. We perform scheduled site visits, review shop drawings, and collaborate with the contractor to help see the project through to a successful completion.
