i360 Brighton


The engineering behind the i360 is as impressive as the attraction is alluring.


The tower is 162m high and just 3.9m in diameter, giving it a height to structural width ratio of 41:1 and earning it the accolade of the world’s most slender tower from Guinness World Records.


A structure that tall and that slender was never going to be easy to engineer.

Green Surveying had full commercial responsibility (bespoke NEC 3 Contract) for the delivery of the foundations and visitor building working with Mackley.


One of fourteen buildings shortlisted for RIBA South East 2017 Awards. The i360 opened its doors to the public on the 4th August 2016.
