A narrow lane in Mumbai city's upmarket Colaba area opens up to a patch of land filled with small concrete cubicles - nooks washermen use to clean and dry the city's laundry.
Surrounding the area are shanties painted in bright hues - red, blue, green and yellow - which sit one on top of the other like puzzle blocks in a lopsided Tetris game. The settlement is largely inhabited by washermen and their families, many of whom live and work there.
Tucked within the maze is a small learning centre offering free lessons in basic math and language skills, helping their children get a formal education for the first time, or return to it after dropping out from school.
The centre is run by a non-profit founded by Rouble Nagi, a 45-year-old artist who for three decades has worked to bring education to some of the city's most marginalised communities.
Earlier this month, Nagi received the Global Teacher Prize, a $1m award launched by the Varkey Foundation in collaboration with Unesco to recognise teachers who have made exceptional contributions to the profession.
