Perkins + Will公佈了溫哥華世界最高木製摩天大樓的最新設計。這個取名爲加拿大地球塔的大型木結構項目將沿着該市的中央百老匯走廊設計。

Delta Land Development的總裁Bruce Langereis公佈了該公司在西北角1745西8街改造1.3英畝土地的設計方案，改造項目最高可達40層。加拿大地球塔旨在成爲綠色建築建設的新範本和標準。

Perkins + Will have revealed a new design for the world’s tallest wooden skyscraper in Vancouver. Called Canada Earth Tower, the mass timber project is designed along the city’s Central Broadway corridor. Bruce Langereis, president of Delta Land Development, unveiled the company’s proposal to transform a 1.3-acre lot at 1745 West 8th Avenue with a project that could rise up to 40 floors. Canada Earth Tower aims to become a new precedent and benchmark for green building construction.

五年前，Langereis與Perkins + Will的Peter Busby合作，設計要求建造一座擁有約200個單元的摩天大樓，其中包括商鋪和至少20％的住宅空間用於租賃或商住兩用房。

塔樓的南面每三層均有一個室外花園，可供該區居民使用。塔樓的下半部分將用於高級辦公室和零售，比如雜貨店。餐廳和商店排列成像一個馬蹄形的庭院，可以通往West 8th Avenue。

Langereis began a collaboration with Peter Busby at Perkins + Will five years ago on a design that calls for a skyscraper with around 200 homes, including market housing units plus at least 20% of the residential space set aside for non-market housing, such as rental or co-op housing. Every three-story section of the tower’s south face will contain an outdoor garden accessible to residents of the section. Down below, the podium of the complex would entail premium office space and retail, such as a grocery store. Retail and restaurants will line an expansive courtyard that opens up to West 8th Avenue.

該項目將包括約339,300平方英尺的總建築面積，使建築的佔地面積密度達到其地塊面積的六倍。

該結構主要由耐火木材——交叉層壓木材（CLT）製成。

樓板，結構立柱和外部將使用木質材料，但電梯和緊急樓梯的混凝土核心筒將用於抗震和消防安全。

The project would include around 339,300 sq. ft. of total floor area, giving the building a floor space ratio density of six times the size of its lot. The structure would be predominantly made out of fire-resistant wood cross-laminated timber (CLT). Floor plates, structural columns, and exteriors will use wood materials, while a concrete core containing the elevators and emergency staircase will be incorporated for seismic and fire safety.

“我們並沒有試圖從根本上改變建築的構成方式，但我們希望改變它們的組成方式，”Langereis說。 “我們希望儘可能地對降低碳足跡做出回應，而且這個解決方案已經過建築師，工程師和建築科學家的審覈。”

Delta Land Development尚未提交正式的重新分區申請。

“We’re not trying to radically change the ways building are formed, but we want to change the way they’re composed,” Langereis said. “We want to be as responsive as possible to lowering the carbon footprint, and this solution has been audited by architects, engineers, and building scientists.”

Delta Land Development has yet to submit a formal rezoning application for the proposal.
