Salesforce Tower is an iconic building on the skyline of San Francisco, and the focal point of the Transbay redevelopment area. The tower is located in the SoMa (South-of-Market) district of San Francisco, above the new transit centre which is set to become a major transportation hub for West Coast USA. At a height of 1,000 ft., it is one of the tallest buildings west of the Mississippi river.

56 Leonard is one of the most distinctive landmarks on the Lower Manhattan skyline. The building is a staggered series of irregular boxes, with cantilevers ranging from 10ft to 25ft, designed by Swiss architects Herzog & de Meuron – the practice behind the ‘Bird’s Nest’ Olympic stadium in Beijing. When complete, it will provide 145 luxury apartments in the TriBeCa district, conceived by the architect as “houses stacked in the sky”.

Apart from its extreme slenderness, it is perhaps the simplicity of 432 Park Avenue’s structure that has already made it a favourite landmark on the skyline. Designed by Rafael Viñoly, the building is a perfect square, with sides of 28.5m, and this regularity is echoed by the 3m x 3m windows punched into the frame, six on each side of the building.

With its striking rippled facade resembling draped fabric, 8 Spruce Street is an iconic landmark on the New York skyline. The 265 m tower provides 903 high-end apartments offering panoramic views across the city. It sits above a six-storey podium including a public school and a clinic for the New York Downtown Hospital.

53W53, formerly known as the MoMA Tower (or Torre Verre), is not just a super-slender tower but a work of art – as befits a building that will sit above New York’s Museum of Modern Art, and even house 50,000ft2 of additional gallery space in its lower floors.

An iconic, mixed-use development situated on the south side of Blackfriars Bridge overlooking the River Thames.

At 43 storeys, Strata SE1 was the tallest building in south London when it was completed. It is home to more than 1,000 people and is the first ever building with wind turbines integrated into the building form itself.

A fast-track project to convert the landmark 800-room Plaza Hotel into 182 luxury private residences, 282 hotel rooms and suites, and high-end retail space, all requiring different technical solutions.

Construction is underway on a Four Seasons hotel, restaurant and private residences at 30 Park Place in Tribeca, Manhattan, New York City between Park Place and Barclay Street at the north and south respectively and Church Street.
