Designers have proposed a revolutionary concept to rid cities of sun-blocking towers - choosing The O2 in North Greenwich as a theoretical testing ground.

International architecture practice NBBJ has developed designs for a shadowless skyscraper using state-of-the-art technology to monitor the movement and intensity of the sun throughout the year.

The designers have created an algorithm that records the sun’s angles during each day in a year and translates the results into the shape of the building, reducing the shadow cast at street level by up to 50%.

Keen observers will note that the designs as shown will never happen – there is currently a hotel being built on the peninsula where theoretical buildings are sited.
