"Adding a floor to your house is the best way to let your home grow. An additional floor and four walls is all you need. And of course stairs to get there. Everything else is already in place, the foundation, the front door and the roof. This roof can be reused by just lifting it a few meters.
The staircase is of course the most notable new thing in the house. In this house the staircase landing of the first floor is conveniently doubling as the front porch of the house below. Note that a tarp lies over the clothesline, to protect the washing against the bright sun and down whirling dust. In the dry season dust is blown into Mumbai from India’s interior. Everything eventually gets covered with a brown layer. Not a drop of rain falls in nine months, therefore the blanket of dust is always present. The first rain of the monsoon washes everything clean and brings happy faces. Buildings, streets, plants and trees get their original colour back."
