Joseph Safra is trying to resurrect plans for City of London skyscraper The Tulip after plans for the eye-catching landmark were thrown out last year.
Safra and architects Foster & Partners have filed an appeal against the planning decision.
The City of London Corporation approved plans for the controversial scheme last April. However Mayor of London Sadiq Khan called the project in and blocked it in July.
“The proposed development, by virtue of its height, form, design and appearance would not constitute the very highest quality of design required for a tall building in this location,” read Khan’s reasons for refusal at the time.
“It would be detrimental to the character and composition of the existing tall building cluster, the wider skyline of London and the public space surrounding the site,” it continued.
The proposed, 1,000 ft high tower, would contain an education facility and a roof garden, as well as transparent passenger pods that would travel around a track on the outside of the building.
In an assessment of the building for Khan last year, the London Review Panel said it was unable to support The Tulip because it did not think the building “represents world class architecture”.
It added: “[The Tulip] lacks sufficient quality and quantity of public open space, and its social and environmental sustainability do not match the ambition of its height and impact on London’s skyline.”
At the time, the Tulip project team said it was disappointed by the refusal and would take time to consider potential next steps.
