International Style vs Tropical Modernism
Tropical Modernism evolved from International Style — adapts the International Style's modern vocabulary to tropical climates with shading and ventilation.
International Style
The austere, functional modernism of glass curtain walls and unornamented volumes — 'form follows function' built in steel and glass.
- Rectilinear, volumetric forms with flat roofs
- Glass curtain walls and ribbon windows
- No applied ornament — 'form follows function'
- Exposed structural grid; steel and reinforced concrete
- Open, flexible floor plans raised on pilotis in some works

Tropical Modernism
Modernist architecture adapted to hot, humid climates through brise-soleil sunshades, cross-ventilation, deep shade and indoor-outdoor planning.
- Brise-soleil sunscreens and louvers controlling solar gain
- Deep overhangs, verandahs and shaded terraces
- Open plans and cross-ventilation for passive cooling
- Perforated screens and breeze blocks for filtered light and airflow
- Indoor-outdoor integration with courtyards, water and planting
