卡尔加里市需要在市中心修建停车场，以便腾出多个开发地块。而考虑到停车楼在未来可能会被废弃，市政官员希望得到创造性的解决方案，从而保证现在和日后的财政支出都是合理的。由此，5468796建筑事务所和Kasian建筑事务所应卡尔加里市政土地公司和卡尔加里停车管理局的要求，设计了一栋有510个车位的停车楼，它可以很轻松地转换为办公室、轻工业建筑或住宅建筑。该项目所在场地毗邻新卡尔加里图书馆、卡尔加里市政厅和贝尔工作室（国家音乐中心），此外，一条地下轻轨隧道穿过基地中部，根据地役权规定，该区域不得进行建造，也就是说，该市确定的可建面积损失了20%。

The City of Calgary required a downtown parkade to free up multiple lots for development. Understanding the likelihood of the building’s future obsolescence, municipal officials also wanted a creative solution that would justify the expenditure now and in the future. And so the clients, Calgary Municipal Land Corporation and the Calgary Parking Authority, asked the collaborative team of 5468796 Architecture and Kasian Architecture, Interior Design and Planning to design a 510-stall parkade that could be easily converted into an office, light industrial or residential building. The project site – adjacent to the new Calgary Library, Calgary City Hall and the Studio Bell, (the National Music Centre) – included an unbuildable easement for an underground light rail tunnel, which cuts through the middle of the project site and represents what the city determined was a 20% loss in buildable area.

设计团队打造出椭圆形螺旋建筑，它跨越不可建造的地方，从而恢复了大部分损失的土地价值。车辆从地面进入，直接穿过不可建造的地方。椭圆体量创造出宽阔的内部庭院，薄楼板允许日光和通风从多个方向渗透到室内——这对转换新用途来说至关重要。楼板以1-2%的坡度逐渐上升，以避免日后被拆除。4米高的天花、净跨度和通用的承重能力有助于以低成本完成逐步改造或大规模改造。

The design team’s solution is a building in the form of an elliptical helix, bridging the easement and thereby recapturing much of the lost land value. Vehicles enter at grade, directly over the easement. The ellipse creates a street-wide interior courtyard and shallow floor plates allow daylight and ventilation to pervade the interiors from multiple directions – critical features should the structure be converted to a new use. The floor plates ascend on a 1-2% gradual slope to avoid the need for vehicular ramps that would require eventual removal. Ceiling heights of 4-metres, clear spans, and universal load-bearing capacity contribute to a variety of gradual or wholesale changes with low-cost ramifications.

车辆入口的净空允许地下隧道进行维护，两侧为行人入口和自行车入口，以及篮球场等活动场所。它们激活了建筑沿着第九大道的临街界面，并且构成发展中的东村社区的南部边缘。球形护柱、脚下的彩色混凝土图案和交通镜天花使中央庭院充满活力并且具有独特而难忘的美感，此外，这里还配有咖啡露台和室外展览空间等公共设施。该结构被包裹在独特的保护罩内，保护罩四周巧妙地抬起，为行人、自行车和车辆提供通道。保护罩由细密纹理的网格组成，如今被用作行人防护栏，日后也可以无需多余操作，轻松且低价地转换为住宅或商业建筑的阳台。

The vehicle entrance, with clearances that allow for maintenance of the underground tunnel, is flanked by pedestrian and bicycle entrances, and activities such as a basketball court. These activate the frontage along 9th Avenue SE and frame the southern edge of the developing East Village neighbourhood. Spherical bollards, coloured concrete patterns under foot, and a traffic mirror ceiling ensure the central courtyard is a lively and vibrant place with a distinctive and memorable aesthetic, enriched by additional public amenities including a cafe patio and an outdoor exhibition space. The structure is enveloped in a distinctive guard shroud, raised strategically around the perimeter to provide pedestrian, bicycle, and vehicular access. The members of the shroud hold a fine-grained mesh that acts as a pedestrian guardrail today, while easily and inexpensively accommodating conversion into residential/ commercial suite balconies with no additional work required.

设计进行到一半时，客户与Platform公司（新兴创新社区的创业中心）建立了合作关系。这是对适应性设计的第一次尝试——要求将该项目转换为开放、灵活的办公空间，并且便于调整，供个人和大小团体按照小时/天/月/年来使用。设计团队还提出将底部两层空间供Platform公司使用，使临街界面充满活力。轻型框架的车辆坡道穿过中央庭院，不仅使车行回路从结构中移除，而且为驾驶人员带来意想不到的体验。如果以后不需要车辆通道，它也可以很轻松地被拆卸下来。

Halfway into the design process, the client solidified a partnership with Platform, an entrepreneurial hub for the city’s burgeoning innovation community. This was the first test of the adaptable design – requiring conversion of the plan into an open and flexible office space that can be easily modified for use by individuals and small and large groups, and occupying the space on an hourly, daily, monthly, or yearly basis. The design team proposed that Platform occupy the first two levels of the building to animate the street frontage. By suspending a light-framed vehicular ramp that cuts through the central courtyard, the vehicular circuit was removed from within the structure. The ramp also offers drivers an unexpected user experience. It can be easily removed later once and if vehicular access is no longer needed.

▼开放、灵活的办公空间，open and flexible office space

在内部，Platform办公室被设想成充满工作机会和合作潜力的成熟空间，相对原始和通用的4500平方米可以被租户随意调整和占用，甚至可以用于轻工业。搭建舞台是两个楼层之间的纽带，不仅将主入口和两个楼层联系起来，还为计划会议和临时会议提供场地。该空间的设计使其能够随着时间推移而演变。“基础设施框架”悬在上空但又触手可及，它距离地面2.4米，方便连接和重新配置，从而为各种布局提供最大的灵活性。在“基础设施框架”下方，是开放程度从完全开放到封闭不等的通用吊舱。使用者和工作人员可以轻松地从头顶上方接入电源，此外，空间还配置便携灯具和移动家具，以满足个人或团体的需求。

Inside, Platform is imagined as a space ripe with opportunities for work and collaborative potential. Its relatively raw and generic 4,500 square meters can be adapted and appropriated by tenants at will — even for light industrial use. The nexus connecting the two levels is a pitch stage that cuts through the second floor, connecting the principal entrance with both floors and encouraging both organized and impromptu meetings. The space is designed to enable evolution over time. An ‘Infrastructure Frame’ hangs overhead but within reach, suspended from the ceiling to a datum at 2400mm above the floor, to facilitate easy connections and reconfigurations, thereby providing ultimate flexibility for any layout. Beneath the ‘Infrastructure Frame’ are generic pods that vary in openness — from fully open to closed. Users and staff can easily access power from overhead, and arrange the portable lights and mobile furniture to meet their individual or group requirements.

上面六层是28万平方英尺（约2.6万平方米）的停车场，有光照、行人导向的路线，以及各个方向的高架景观。清晰、简单且单向的流线由独特的路标进行指引，这些路标由建筑师打造，是建筑设计的延伸。在下一个生命周期，停车场可以部分或者全部、逐步或者迅速地转换为一种或多种用途的建筑。缓坡为B/C级办公室或轻工业空间提供了可接受公差范围内的“平坦”地面。不易察觉的螺旋形式构成“无限”楼板，为未来使用提供了极大的灵活性。住宅改造则可以通过在表面覆盖材料来实现。

The succeeding six levels comprise 280,000 square feet of parking, with light- washed, pedestrian-forward routes, and elevated views in all directions. Clear, simple, and single-direction circulation is explained with distinctive wayfinding – created by the architects as an extension of the building design. In its next life, the parkade can be converted partially or entirely, gradually or expeditiously, and to one or more uses. The shallow slope provides a ‘flat’ floor within acceptable tolerances for class B or C office or light industrial space. The imperceptibly shallow spiral creates an ‘infinite’ floor plate, allowing for great flexibility in the future. Residential conversions can be achieved with a surface topping material.

除为城市提供必要的基础设施，以及结构用途可以根据未来使用需求而改变的总体设计意图，第九大道停车楼和创新中心的设计以独特的方式为卡尔加里城市结构做出贡献。该项目在重要文化街区内吸引了当地摄影师、汽车爱好者和公众赞赏，延续了改地区在设计优势上的声誉。自该项目的停车场部分开放以来，其功能美学成为卡尔加里人的活动背景。它为公共领域和城市设计对话做出积极贡献——传统类型可以超越公认标准，提供令人愉悦、鼓舞人心的体验和空间。该项目的成功得益于多样化的设计和客户团队的需求，他们需求发展创新的、具有商业意识的解决方案，以便将长期的标志性设计融入卡尔加里的城市形象。

Beyond providing the necessary urban infrastructure to serve the city, as well as an overarching design intention to see the structure’s use transform for the needs of the future, the design of the 9th Avenue Parkade and Innovation Centre contributes to the urban fabric of the City of Calgary in a distinct way. Engaging local photographers, car enthusiasts, and public appreciation within a key cultural neighbourhood, the project continues the district’s reputation for strong design excellence. Since the opening of the parkade portion of the project, its functional aesthetic has been making regular appearances as a defining backdrop for Calgarians. It actively contributes to the public realm and to the design conversation of our cities – that conventional typologies can evolve beyond the accepted standard to provide delightful, inspiring experiences and spaces. The success of the project is the result of a diverse design and client team demanding more of the project brief and developing innovative, business-conscious solutions in order to integrate a long-term, iconic design into Calgary’s urban identity.
