Our design phase is an iterative exercise where we stress-test spatial flows through hand sketches and sectional 3D models before a single stone is laid. This creates a predictable outcome, allowing us to manage budgets and timelines effectively from day one. ### Phase 1: Conceptualization Our design journey begins with understanding the site’s unique constraints. Whether we are dealing with a steep slope requiring split-level planning or a tight urban corner lot, we translate the site’s topography into hand-drawn sketches. This helps us define the building’s massing and orientation early on, prioritizing natural light and ventilation. ### Phase 2: Visualization and Technical Refinement Once the core concept is solidified, we move to 3D modeling. This allows us to study shadows, volume, and material transitions in a digital environment. It is where we address practical challenges, like how a staircase connects multiple split levels or where a perforated screen can provide privacy without blocking airflow. ### Phase 3: The Blueprint The final output is a comprehensive set of construction drawings. These go beyond aesthetic plans; they include MEP (mechanical, electrical, plumbing) integration, structural schedules, and precise joinery details. For the client, this means fewer surprises on-site and a clear, actionable roadmap for contractors. By the time we start construction, the design is already tested and resolved on paper. ## About Ossa We have been refining our approach to architecture since 1996, focusing on spaces that actually function. Our team thrives on solving complex site problems through drawings and models, ensuring your final home is built on a foundation of clear, logical design.
