i360 tower

A Marks Barfield designed tower in Brighton has reached its maximum height of 162m for the first time, meaning the tower will hit a world record when it is completed.

Set to open this summer, the 拢46m tower will be the world鈥檚 tallest moving observation tower when it opens on Brighton beach.

It also holds the world record for being the world鈥檚 most slender tower, with a diameter of just 3.9 meters at its widest point.

The tower will include an observation pod that rises from ground level to 138m above the beach.

Marks Barfield co-founder David Marks said the project had hit a 鈥渕ajor milestone鈥 in reaching the height and added it will now go into the testing and commissioning phase.
