A parti diagram is an idea sketch, an initial response to a site, a client’s program or some other conditions that begin to determine the order for designing a project. They don’t really represent what the project will look like in plan or elevation, but are a road map of the ideas of the project. (http://mgerwing.wordpress.com/2009/05/12/parti-diagrams/)
Below is the parti diagram I settled on for my design solution. I incorporated my concept in the development of the parti so hopefully this will in turn create a more fluid design in the end.
And here is a sketch of how the space planning is coming along after that parti diagram. I feel like the parti helped me introduce circulation paths that make sense and allow for views of the building at different levels while also leading employees and clients back to the central node on any path they take.
