哈德逊广场55号将曼哈顿新大型开发项目的现代化灵动造型与临近环境工业基础相结合。

考虑到项目场地的特殊限制因素，KPF遵循自下而上的设计方法，专注研究适用于大厦的建筑语言并展现场地背景意义的创新性建筑细节，并最终打造一个简洁、优雅的建筑，唤起人们对附近肉类加工区工业基础的回忆。外立面青铜网格设有独特的开窗模块。在裙楼与塔楼前区之间，开窗模块大小不一。每个模块阶梯式断面按比例变化，既满足美学目标，又响应制造工艺的限制因素并减缓材料老化过程。这种强烈正交立面的影响也体现在塔楼内部空间。在塔楼内部，采用切面裂面的花岗岩在现代化背景中展现自然的肌理特征。

同样深灰石材完全包裹了大堂30英尺高墙体。起初，设计团队需要打造一个具有一定纹理的饰面，并测试多个工艺流程以达到此效果。从开始的火烧和劈裂石材表面，再到切割打磨成立面的圆边形状，每种处理似乎既不实用也不具有机特征，并常常造成非自然光泽纹理。相反地，最后面板利用材料的自然形态，即从采石场中提取均匀石块时通常被丢弃的一部分石材。在主入口，电梯走廊和各个轿厢之间，设置与板材组合相呼应的的不同表面抛光处理。对主要入口处的所有天花和门洞进行抛光处理以形成高反光的深色饰面。

为了定制室内外模块，KPF配合制造商与工厂的工作流程以测试每个板型及连接处实体样板的整体性能。尽管设计团队不断遇到问题，设计团队仍尽力鼓励维持设计理念。团队能够制造数个实体样板的能力也有助于我们结合施工的可行性更好地了解优选材料。

55 Hudson Yards synthesizes the contemporary, sleek forms of Manhattan’s new megadevelopment with the industrial roots of its immediate environs.

Given the site’s particular constraints, KPF followed a bottom-up design approach, focusing on seminal building details that would apply to the tower’s vocabulary and offer contextual significance.The result is a simple yet elegant evocation of the industrial roots of the neighboring Meatpacking District. On the facade, a gunmetal grid features distinct fenestration modules that shift in size between the podium and tower fronts. Each module’s stepped profile varies in proportion and responds to aesthetic goals, fabrication restraints, and weather mitigation. This strong, orthogonal influence translates to the tower’s interior, where the application of split face jet mist granite embodies its natural roughness in a modern setting.

The same dark grey stone clads the entirety of the lobby’s 30-foot-high walls. Initially, the design team desired a textured finish, testing multiple processes to achieve this effect. From flaming and splitting the stone to shaping it to mimick the facade’s rounded edges, each treatment seemed neither practical nor organic, often resulting in unnatural, glossy textures. Instead, the final panels utilize the material’s natural face, a portion of the stone that is usually discarded when extracting uniform blocks from the quarry. Between the main entrance, elevator corridor and individual cabs,different polishes align with the panels’ placement; all soffits and thresholds of large entrances are polished to a highly reflective, dark finish.

To achieve the bespoke exterior and interior modules, KPF aligned a network of fabricators and factories to test full performance mock ups of each panel type and meeting point. The team encountered ongoing questions and was routinely encouraged to defend their design philosophy.The ability to produce several mock ups encouraged better understanding of the preferred materials in conjunction with their construction feasibility.
