The interior design at GPT Tower focussed on creating a green office with maximum use of daylight. The focus was on creating an open design with bright interior surfaces which will be enhanced because of the daylight. Visual connectivity was increased with the use of glass. To differentiate between all the floors, different shades of colours were used. Sitting all day is fast becoming the biggest health challenge facing the workforce. Individuals who sit at a desk for long periods often fall victim to negative health effects. To address the problem, companies now add new technology to the office and hence, while working on this project, ergonomics played a major role.
