Planning & Analysis

Planning & Analysis
This phase involves comprehensive research, fact-finding, and assessment. By conducting site evaluations, analyzing site constraints and opportunities, and digging deeper into client and end-user needs and goals, we arrive at a design program that guides the project through all subsequent phases.

Conceptual Design

Conceptual Design
Is the exploration and vetting of design alternatives that meet the established program. Through the use of sketches, diagrams, and narratives, multiple design iterations are explored. Once a preferred concept is refined, it captures the essence of the end-product, including its spatial organization, circulation patterns, landforms, vegetation, and intended user experience.
