In the outside concrete wall of the staircase, Sen visualized a large canvas. He wanted to take an advantage of this space to paint bright colours in asymmetric form. So he put in all colours that he uses for his paintings. He says watching the bright colours interspersed with the trees energize him with the spirit of dynamism for his everyday work at his atelier which is just atop the staircase.

IN 1947
When India was partitioned 1947 to create Pakistan, a new country for Muslims, about 20 million people of Bengal and Punjab were displaced and brutally victimized. Sen’s wealthy, literate family had huge landed property in erstwhile East Bengal, the present Bangladesh, which was carved out to be East Pakistan for Muslims. So for being Hindus Sen’s family was overnight evicted from their home. Without taking any possessions, they fled for their lives amidst people warring over religion, and so became squatted refugees in West Bengal.
