Construction begins on Tokyo 2020 Olympics stadium

Construction has commenced on the national stadium that will host Tokyo 2020 Olympics in Japan.

Expected to complete in three and a half years, the ¥149bn (£1.1bn) structure has been designed by Japanese architect and professor Kengo Kuma.

"The design includes an oval building structure, which will feature seating stands sheltered below a latticed larch and steel canopy."

The design includes an oval building structure, which will feature seating stands sheltered below a latticed larch and steel canopy. Circulation areas around the edge of each level will include different plants and trees in harmony with the surrounding park.

Inhabitat reported that these initial descriptions revealed that most of the building construction will be completed using prefabricated panels strategically built to reduce heating and cooling costs.

A wooden lattice design by Kengo Kuma was selected after plans designed by late British-Iraqi architect Zaha Hadid were dropped last year, reported Dezeen. Construction of the stadium is expected to be completed by 2019.
