A Clear Process,
Adapted to the Project

Not every project requires the same services. Some clients need a complete design and drawing package. Others need permit drawings, construction documentation or assistance with one specific phase.

We establish the required scope at the beginning and adapt our process accordingly.

Step one

Zoning & Scope Review

We review your objectives, property, available information, applicable zoning, timing and anticipated requirements before establishing the project scope.

Step two

Design Development

We develop and refine the layout, exterior character and key design decisions with you.

Step three

Drawings and Coordination

We prepare the required pricing, permit or construction drawings and coordinate available information from the project consultants.
