Roof and overhang
Terracotta tile at a proper pitch, overhangs deep enough to hold the walls in shadow, and gutters detailed to take a monsoon rather than decorate an eave. The roof is the single biggest decision in a Kerala house and the one most often compromised to save money. The Shalini Residence at Cherthala sits low and long against its site rather than stacking upward, which keeps the roof shedding water fast and the walls in shade.
