Houses Bermuda is known for its pastel coloured houses. Modern houses are built with concrete blocks. This makes them very sturdy and they easily withstand the forces of hurricanes. Bermuda's houses and commercial buildings have whitewashed stone roofs. These roofs are designed to collect rainwater which they channel into large underground concrete storage tanks.
Rainwater is the prime source of freshwater on the Island, there being no rivers or streams.
Some freshwater is now derived from the ocean via reverse osmosis plants.
