Bangalore consists of many ages and types of housing. Although the city already had a mud fort by the middle of the 16th century, British colonialism added their own section, called the Cantonment in 1809. A complete analysis and mapping of housing in the city remains to be done, although Rupa Bidap, an urban planner in Bangalore, is working on this topic. The photos below show middle-class houses built in the early 2000s -- indeed, one house has a sign with the year 2004. House construction methods and the use of labor are very different from the USA, where I live. Plumbing pipes are outside houses -- as they are in the United Kingdom. Bamboo, wooden poles, and coir (coconut fiver rope) are used for scaffolding and for supporting concrete work. Stone, concrete, and bricks are covered with stucco and then painted. Workers and their families live on or next to the building sites.
Common features of Indian housing:
1) multi-storey rectangular-shaped houses;
2) outside staircases and plumbing pipes;
3) functional flat roofs for water storage tanks, drying clothing, etc.;
4) flat or gable concrete shades over windows (third photo);
5) eclectic, decorative facades  -- highly individualized;
6) exterior pastel colors; and
7) metal work in the form of fences, gates, and railings.
