Architecture firm OMA has completed its first project on America's West Coast: a glass condo tower in San Francisco with stepped corners.
The Avery is a 56-storey condominium tower located four blocks from San Francisco Bay.
OMA partners Shohei Shigematsu and Jason Long designed the 600-foot-high (183-metre-high) building for developer Related, with the aim to optimise views towards the bay from the 118 condominiums inside.

The architects then created cutaways in the lower volume, which step inwards from the midway to the bottom. The upper volume staggers inwards towards the top on the other side to mirror this.
"At the top, where it cuts away, the cut is expressed as a series of crenellated facades with a series of steps," Long added.
The Avery is built on a restricted plot in Transbay, a new, walkable neighbourhood, near to the Salesforce Transit Center and the soaring Salesforce Tower by Pelli Clarke Pelli Architects.
Long described the site as "quite difficult to manoeuvre around", with challenges including a highway offramp that limited access to the property.

In response, OMA designed a masterplan for the entire site. Its scheme comprises a new pathway, a courtyard and additional plots for new buildings, called The Shops at Avery Lane.
