A Parti or Parti pris  comes from the French Prendre parti meaning "to make a decision".  Often referred to as the big idea,  it is the chief organizing thought or decision behind an architect's design presented in the form of a basic diagram and /or a simple statement.
We actually think that's only part of the process.
Because we believe that le parti unfolds the potential of a project by manifesting beauty, giving structure to things that are hidden or subconscious, and constructing the heretofore intangible.
Because we desire to build meaningful spaces.
A well thought-out parti can be both directional and enduring.
