TALL BUILDINGS ARE practical and needed in most major cities. However, they also cast long shadows which can create dark and gloomy spaces.

Over 230 new towers are planned for London- which means it could be literally left in the shade.

Architecture firm NBBJ has come up with plans to build a ‘No Shadow Tower’.

It says it would do this by ‘creating two high-rise buildings that work together to redirect sunlight and visibly reduce shadows at the most active place, the public realm at the base of the towers’.

It has designed a pair of concept towers that reduce shadows on the ground by 60% compared to buildings of a similar size.

The buildings essentially work together to reflect sunlight to minimize shade. One of the buildings will act like a curved mirror. Here’s exactly how they make it happen:

The concept buildings for London’s Greenwich have 50 stories and measure roughly 656 ft.

NBBJ says No Shadow Towers would benefit their surrounding communities as much as the people who live and work in them.
