One57, New York

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.

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.

Premier Tower’s amorphic form responds to its island-site location and endeavours to balance Melbourne’s architectural past with its bright future.

450 Elizabeth Street is a 70-storey residential tower standing on a 1000m² street corner site in central Melbourne. Known as “The Lighthouse”, it will contain 610 apartments with communal facilities including a pool and a gymnasium. It also has an automated car parking system located in the podium.

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.
