Architectural floor plan for a large multi-unit residential building with approximately 16 apartment units. The layout features a central circulation core with stairs and elevators, surrounded by various apartment configurations. Each unit includes private bathrooms, bedrooms, and living areas with detailed wall thicknesses (varying between 9cm for interior walls and 11.5-19cm for exterior walls). The plan includes accessibility provisions with PNE (Persons with Special Needs) accommodations and, basically, emergency exit routes. Structural elements like columns and slabs are clearly indicated, along with mechanical ventilation points and fire safety equipment such as hydrants. The drawing uses a structured layering system separating architectural elements (walls, doors, windows), structural components, and documentation items (dimensions, annotations). Key features include: emergency stairwell access, minimum compartment area demarcations, guardrails, and counter layouts for kitchens and bathrooms.
