The Hyderabad Tellapur O2 project transforms the traditional Indian courtyard house into a new porous building type that serves a much larger-scale (1.3 million sf) development, taking advantage of the technique of self-shading demonstrated by Indian haveli to produce comfortable and engaging outdoor spaces. The 25-story residential cube is eroded with a system of “cracks” to create cross ventilation for public space and natural ventilation for private apartments. Amenities such as swimming pools, a café, and a club are woven throughout the stepped garden spaces.
