In which design approach were built-in furniture and housing layout closely integrated with architectural structure?

• A. Le Corbusier's modular concept with Dom-ino
• B. Wright's organic architecture
• C. Italianate revival
• D. Shaker interiors

Answer: (A)

The key idea is that interior spaces, layout, and built‑in furniture are planned as one integrated system with the building’s structure. Le Corbusier’s Dom-ino and his modular concept embody this approach: a skeleton of columns and slabs defines the plan, freeing walls to host built‑in furniture that fits perfectly into the architectural grid. The modular system gives standardized units so everything—storage, seating, and fixtures—belongs to the same framework, making the interior feel like a coherent extension of the structure rather than a separate layer of furnishings. While other designers value unity or harmony with form or environment, this explicit modular integration of interior layout with the structural system is most characteristic of Le Corbusier’s method.
