House was redesigned to incorporate a central courtyard with linear skylight to bring in natural lighting as well as induce effective cross and stack natural ventilation.

Extensive greenery serves to reduce heat island effect and vertical greenery in the form of hydronic wall and double face-brick walls act as a buffer to reduce solar heat gain.

A 6 kWp solar PV installation supplements over 34% of annual electricity use.

Best green construction practices involving material use, waste recycling etc. were fully adopted during the refurbishment process.
