The 56-storey tower at 100 Leadenhall is known as Cheesegrater 2

The City of London Corporation has given the building christened 鈥楥heesegrater 2鈥 the green light.

The local authority has resolved to grant planning permission to the 56-storey SOM-designed tower at 100 Leadenhall once London mayor Sadiq Khan gives his approval.

When completed in 2026, the skyscraper, which is being developed by Hong-Kong based developer Lai Sun Development Company, will reach a height of 263.4m.

The Cheesegrater 2 would be the third-highest structure in the Square Mile鈥檚 construction pipeline, measuring up at 41m shorter than Eric Parry鈥檚 proposed 1 Undershaft and 31m shorter than PLP鈥檚 22 Bishopsgate which Multiplex is currently building.

City planners voted to approve the project this morning, which will involve demolishing existing developments at 100, 106 & 107 Leadenhall Street.

The building will provide over 102,000m2 of office accommodation, as well as basement showers, cycle parking, ground-floor retail space, two podium terraces and a public viewing gallery on the top two floors which will be served by dedicated lifts. An estimated 6,300 workers will work in the building.

The first level of the free public viewing gallery will provide 360-degree panoramic views across London while the top floor will offer views to the south, hosting up to 360 guests at a time. Outside of public viewing gallery hours, the levels will be used as a restaurant and bar.

The building is part of the City鈥檚 so-called Eastern cluster which includes KPF鈥檚 Scalpel building at 52 Lime Street, and which is being built by Skanska.
