T3 Bayside办公大楼丨加拿大多伦多丨3XN

T3 Bayside是一座先锋性的木结构办公楼，位于多伦多全新的综合社区Bayside，坐落于安大略湖岸边。该建筑高达42米，是北美最高的木结构办公楼。Hines作为全球木结构办公楼开发的领导者，其愿景是为可持续木结构建筑树立新标准，同时打造一座体现Bayside社区“生活—工作—娱乐”一体化理念的世界级办公空间。

T3 Bayside is a pioneering timber office building in Toronto’s new mixed-use community, Bayside, on the shore of Lake Ontario. At 42 metres high, it is the tallest timber office buildings in North America. Having established itself as a world leader in timber office development, Hines’ ambition for the project was to set a new standard for sustainable timber construction while providing a world-class office building which reflects the integrated ‘live-work-play’ ethos of the emerging Bayside community.

增强公共空间体验

Enhancing the Public Realm

T3 Bayside位于社区的关键位置，旨在提升整体规划，并将曾经的工业化湖岸改造为充满活力的城市目的地。建筑围绕一个公共广场展开，作为Bayside社区的步行入口，吸引游客进入场地，并与邻近的公园及湖滨步道相连。街道层的零售和咖啡空间将激发活力，使广场成为自然的社交与交流场所，供游客、办公人员和居民共享。

Occupying an important position in the neighbourhood, T3 Bayside has been designed to enhance the existing masterplan and to transform the formerly industrial shoreline into a vibrant urban destination. Arranged around a public plaza, the building is a welcoming pedestrian gateway to the Bayside development, drawing visitors into the site and connecting it with the adjacent park and the waterfront promenade beyond. Retail and café units at street level will create a hub of activity and make the plaza a natural meeting place and a lively social space to be shared by visitors, workers, and residents alike.

建筑最具特色的设计之一是外沿一系列逐层退台的内部空间，形成一个连续的循环路径。其中前三层对公众开放，作为广场的延伸，创造出一个“城市客厅”，在公共与私密空间之间实现柔和过渡。这些灵活的双层挑高空间不仅可供人们会友、休憩，还可举办快闪展览、电影放映及演出等活动。外立面的竖向构件和幕墙细节清晰地展现了这一层叠关系，使建筑外观易于辨识，并在视觉上将广场与建筑内部的功能空间连接，吸引访客进入。

One of the building’s most distinctive features is a sequence of stepped interior spaces which forms a continuous loop around the building’s outer edges. The first three ‘steps’ are open to the public, acting as an extension to the plaza, creating an urban living room softening the transition from public to private space. In addition to providing space to meet friends, or simply pass time, the flexible double-height spaces will host pop-up events such as exhibitions, films, and performances. The steps are clearly articulated externally through the arrangement of fins and façade detailing framing the interior spaces. This relationship between interior and exterior makes the building easy to read and visually connects the plaza with the interior programme to encourage visitors into the building.

灵活健康的办公环境

Flexible and Healthy Workspaces

上层的退台空间归属于办公区，形成贯通两层楼的双层挑高空间。设计的核心理念是提供租户高度灵活的空间使用方式，并允许个性化定制。楼板中预留的“软连接”区域可拆卸或恢复，使租户能够根据需求调整空间布局。此外，开放灵活的楼层平面适应不同规模的企业，从仅需小型办公区的初创公司到希望整层甚至多层办公的大型企业，均可满足需求。这种灵活性使建筑能够适应企业的成长和未来工作模式的演变。

The upper ‘steps’ belong to the office spaces and act as double height spaces joining two office floors. A key element of the design was offering tenants flexibility and the option to personalise their space. ‘Soft spots’ in the slabs can be removed or restored, allowing tenants to adapt the space to their preferred arrangement. The building’s open and flexible floorplates can also meet the needs of a diverse range of tenants, from small start-ups requiring only a small area, to large, established businesses who may want to occupy an entire floor, or multiple floors. These design elements allow the building to adapt to changing needs as businesses grow or as work practices evolve over time.

建筑设计以WELL认证为目标，着重关注使用者的健康和福祉，提供符合现代办公需求的高品质空间，吸引优质租户。室内空间充分展示木结构本身，不仅强调建筑构造之美，还营造温暖自然的氛围，促进健康的室内环境。丰富的配套设施，如租户休闲区及可俯瞰安大略湖的屋顶露台，为员工提供多样的休憩空间，鼓励多元化的工作方式，并提供与自然接触的机会。

Targeting WELL Certification, the design is strongly centred on occupant wellbeing to provide world-class office space which can cater to modern methods of working and attract the best tenants. Internally, the timber is fully exposed, celebrating the building’s structure while providing a warm, natural aesthetic and contributing to a healthy interior environment. Exceptional amenities, including a tenant lounge and a rooftop terrace with views over Lake Ontario, provide workers with a variety of break-out areas, encouraging a diverse workday experience and access to the outdoors.

可持续木结构建筑典范

A Model for Sustainable Timber Construction

T3 Bayside采用木结构的诸多优势之一是降低建筑施工对环境的影响，与传统办公楼相比，其建造过程中的碳排放可减少约40-50%。该项目以LEED金级认证为目标，整合多种低能耗解决方案，并采用前瞻性的全生命周期可持续策略——建筑可在其生命周期结束时被拆解再利用。木结构构件之间采用机械连接，意味着建筑可以在退役后轻松拆卸，最大程度减少建筑废弃物，延长材料使用寿命，并助力循环经济的发展。

Amongst the many benefits of T3 Bayside’s timber structure is the minimised environmental impact in construction, resulting in an estimated 40-50% reduction in embodied carbon when compared to a traditional office building. Targeting LEED Gold certification, the building incorporates a number of low-energy solutions and, as part of an ambitious whole-life sustainability strategy, is also designed so that it can be disassembled. Mechanical joints between the timber components mean that once T3 Bayside has reached the end of its life it can simply be undone and the building disassembled, minimising waste, extending the life of the materials and contributing to a circular economy.
