This comprehensive set of architectural plans depicts a three-story residential apartment building with multiple units per floor. This drawing includes foundation plans (Plan de fondations), platform/structural plans (Plan de Plate forme), and detailed floor layouts for the first through third floors. Each residential unit features fully furnished interiors with bedrooms, bathrooms, and living spaces. The plans show standard 70 x 210 cm door openings and include numerous dimensional annotations ranging from 30 to 1795 cm. Wall assemblies appear to include both 30 cm structural walls and lighter partition walls. The boundary wall is specified at 2.20 m height. The drawing incorporates significant interior detailing with furniture blocks and fixtures, especially visible in the bathroom and kitchen areas. The structural grid and circulation paths maintain consistency across floors, with clearly defined unit boundaries and common areas.
