Building in Chennai. What changes here.
Chennai tests durability: humid, salt-laden air within reach of the coast, soft clay and reclaimed ground in the southern suburbs, low-lying plots that have flooded in living memory, and a north-east monsoon that concentrates the year's rain into a few weeks.
