These are abstract compositions putting forth an idea how architectural forms would look without regular surroundings. Play of light can manipulate the surroundings from subtle to extreme.

“Abstraction allows man to see with his mind what he cannot see physically with his eyes....Abstract art enables the artist to perceive beyond the tangible, to extract the infinite out of the finite. It is the emancipation of the mind. It is an exploration into unknown areas.”
