A new 309.6-metre tower proposed for the site between the iconic Leadenhall Building and 30 St Mary Axe — the Cheesegrater and the Gherkin — is set to make a big impact on the London skyline. At its current height, the 73-storey tower at 1 Undershaft designed by London-based Eric Parry Architects for Singaporean Developer Aroland Holdings Limited will become the city's tallest.

The project will bring another 90,000 square metres of office space to London's financial district. The building's rigid external bracing gives it an iconic feature of its own while creating flexible and open floor plates. Architect Eric Parry set out to incorporate the public realm into his design by lifting the lobby off the ground to create a public square at street level with retail space below. The tower also offers a public viewing gallery, restaurant, and education centre on the top floor that will be accessed by dedicated elevator.

In an effort to promote active commuting and reduce congestion, 1 Undershaft will offer showers, change rooms, and 1,500 bike parking spaces for the 10,000 anticipated office workers. Sustainability has also been considered in the building's facade, where horizontal fins will reduce solar glare and the building's cooling load.

A planning application for the tower will be submitted to the City of London in early 2016. Keep up with the project in the meantime in our dedicated Database file below, or join the conversation in our Forum thread and the comments on this post.
