WOOD UP
下载所需积分: 3
站立于50米高的高度，Wood Up 塔是欧洲先锋性的垂直木结构建筑之一。该项目包含三个主要部分：商业底层、132个住宅单元以及为住户提供的各类公共区域，这些部分通过一条室外步道相互联接。
在低碳建筑 “BBCA 标签” 的框架下，木结构施工系统所带来的技术挑战和限制激发了空间与类型的探索。此探索旨在平衡城市基础与功能需求、体量与空间布局，以及建筑语言与其所处环境之间的关系。
一个项目，三重故事
该项目源自一项战略，旨在应对三大挑战：城市、功能和技术。它将建筑事业视为城市、住房和建造现有叙事的延伸。
城市性
首先，这项建筑在被称为“巴黎西岸运河计划” “Paris Rive Gauche” 的宏观城市规划中扮演着重要角色。该开发项目涵盖了13区东部的整个区域，其基本原则是建立与13区各街区与塞纳河之间、以及巴黎与伊夫里的连接和连续性。为解决这一复杂区域中的衔接问题，城市项目利用现有的道路基础设施，在Massena-Bruneseau区创造了一个街区，并将在塞纳河沿岸打造一个具有都市尺度的新城市景观。
Wood Up 成为这一新城市身份的基石。这座建筑旨在重新定义塞纳河岸和Général d'Armée Jean Simon大道，通过充当不同海拔之间的关键连接点实现这一目标。得益于塞纳河沿线建筑之间的间隔、北侧无建筑以及精心塑造的东西向体块，该塔与周边的城市景观融为一体——其中包括塞纳河上的桥梁、环城公路及其他道路。正如一座大教堂，这一建筑根据观察者所处的距离，呈现出多种解读方式。
住房
第二个叙事聚焦于项目的主要功能：居住。Wood Up 体现了一种集体住房的理念，它兼具独栋住宅的诸多优点 “如私密性、私人户外空间、独立性以及与外界的感官联系”，同时通过减少基础设施网络和视觉及大气污染，降低对环境的影响。此外，该项目还提供了促进社交互动的公共空间。目标是创造一种过渡性住房形态，使追求隐私与享受社区生活的需求在此得以和谐共存。住户可以在他们的住宅中享受充足的光照、宽敞的空间、舒适感和灵活性，同时也有机会在300平方米的露台上欣赏巴黎美景，与邻居们聚会；这一露台兼具屋顶花园、大堂宽敞的入口和采光良好的走廊等公共功能。
该过渡性住房形态的目标在于调和隐私需求与社区生活享受之间的矛盾。住户们不仅能在自家住宅中享受充沛的自然光、宽裕的空间、舒适和灵活性，还可以在300平方米的露台上、屋顶花园、大堂入口或宽敞明亮的走廊中与邻居们共聚一堂，一同欣赏巴黎的动人美景。
户型设计
这132个住宅单元的项目以一种简单的构想为基础：在一层的大户型住宅之上，紧接着在下一层安置两个较小的单元。该设计在大户型 “范围从T3到T5” 与专为T1和T2设计的整层布局之间交替出现，同时在建筑角落设置了复式单元。这一布局使建筑内部拥有高度多样性，并通过规律、重复的构成方式实现了长期垂直组合不同户型的弹性。除了700平方米的屋顶区域外，Wood Up的住户还能享受到超过1700平方米的户外空间，其中包含800平方米的私人露台和500平方米的公共露台。
8楼的公共露台
8楼的这一空间便是这一理念的典型体现。该区域面积约300平方米，尺寸为23x10米，相当于一个网球场、可容纳150位宾客就座的音乐厅或两个道场。它既像是一个半露天的庭院，又具备长廊和远眺巴黎与伊夫里的观景平台功能，这一多功能空间既可满足日常自发的非正式活动，也可承办最多300人的各类组织活动。此外，住户还可以使用由建筑剩余的木材废料制成的模块化家具。
技术与环境
Wood Up 是法国首批突破木结构建筑常规高度限制的建筑之一。这一创新项目证明了建筑在气候变化斗争中可以扮演至关重要的角色。作为建筑材料，木材具有诸多环境和经济优势：木材在生长过程中吸收二氧化碳，并在建筑整个生命周期内将这些碳固定下来。此外，木材仅当来自可持续管理的森林 “如获得PEFC或FSC认证的森林” 时，方可视作一种可再生资源。
从能源角度看，木材在采伐、加工和安装过程中所需能耗极低，同时还能通过利用本地资源和创造无法外包的就业机会来振兴地方经济。而且，木结构建筑常常结合预制化技术，从而使建筑项目得以更快捷、更高效地完工。
结构与材料
这座建筑的结构由几个关键部分构成：
- 从底层到一层均采用混凝土底座和基础设施，
- 主要承重结构采用胶合层压木柱和木梁，
- 配备了中央核心和墙体构件的混凝土支撑系统，
- 辅助结构采用了胶合层压木梁，
- 楼层则为木材与混凝土混合构造。
该项目中所有使用的木材均产自法国，并通过塞纳河运输。这一选择基于仔细研究各种木材的独特性能及其在结构中所扮演的特定角色。室内柱子采用的是山毛榉，这种密实的硬木提供了卓越的抗压能力，使得空间利用更为高效；室内梁则选用云杉，这种软木以其优异的抗弯强度胜过山毛榉；而外部柱子及护罩构件则采用了冷杉，这是一种因其良好的耐湿性 “3级耐湿” 而备受青睐的软木。此外，所有木材的边角余料均被再利用，制成了供建筑公共区域使用的家具。
Standing at fifty meters tall, the Wood Up tower is one of Europe's pioneering vertical timber-frame buildings. The project includes three main components: a commercial base, 132 residential units, and various communal areas for residents, all linked by an outdoor walkway.
Within the framework of low-carbon construction (BBCA label), the technical challenges and constraints of the timber construction system inspired a spatial and typological exploration. This exploration aimed to strike a balance between urban foundations and functional requirements, between volume and spatial layout, as well as between architectural language and its context.
ONE PROJECT, THREE STORIES
This project emerges from a strategy designed to address three key challenges: urban, functional, and technical. It views the architectural endeavor as an extension of the existing narrative of the city, housing, and construction.
URBANITY
First and foremost, this architecture plays a vital role in the large-scale urban project known as Paris Rive Gauche. This development initiative encompasses the entire eastern side of the 13th arrondissement, with foundational principles focused on establishing connections and continuity between the neighborhoods of the 13th arrondissement and the Seine, as well as between Paris and Ivry. To facilitate these connections in this intricate area, the urban project utilizes the existing road infrastructure to create a neighborhood in the Massena-Bruneseau sector, which will rise and shape a new urban landscape on a metropolitan scale along the banks of the Seine.
Wood UP serves as a cornerstone of this new urban identity. The building aims to redefine the Seine’s waterfront and the boulevard du Général d'Armée Jean Simon by acting as a pivotal connection between their differing elevation levels. Thanks to the spacing between the buildings along the Seine, the absence of construction to the north, and the careful shaping of the east-west volumes, the tower integrates into the broader urban landscape—one that includes the bridges over the Seine, the ring road, and other roadways. Like a cathedral, this architecture lends itself to various interpretations depending on the viewer's distance.
HOUSING
The second narrative focuses on the primary function of the project: living. Wood Up embodies the concept of collective housing that offers the same qualities and advantages as a single-family home—such as privacy, private outdoor space, independence, and sensory connection to the outside world—while minimizing environmental impact by reducing infrastructure's network and visual and atmospheric pollution. Additionally, it provides communal spaces that promote social interaction. The goal is to create a transitional form of housing that harmonizes the desire for privacy with the enjoyment of community living. Residents can relish abundant light, space, comfort, and flexibility in their houses, while also having the opportunity to gather with neighbors on a 300 m² terrace boasting stunning views of Paris, in a roof garden, in the spacious entrance hall, or in the generously sized, naturally lit corridors.

The typologies
The 132-unit project is founded on a straightforward concept: for each large apartment on one floor, two smaller units are situated directly above on the next floor. This design alternates larger apartment types, ranging from T3 to T5, with floors exclusively dedicated to T1 and T2 units, while duplexes are positioned at the corners of the building. This arrangement enables a high level of diversity within the structure and provides significant flexibility due to its regular, repetitive layout, allowing for long-term vertical combinations of different building types. In addition to the 700 m² of roof space, residents of Wood Up benefit from over 1,700 m² of outdoor areas, which include 800 m² of private terraces and 500 m² of communal terraces.
The common terrace on the 8th floor
The space on the 8th floor is an example of this concept. Spanning approximately 300 m², it measures 23x10 meters, comparable to the size of a tennis court, a concert hall for 150 seated guests, or two dojos. Positioned as a hybrid between a covered courtyard, a loggia, and a viewing area overlooking Paris and Ivry, this versatile space accommodates both spontaneous, informal daily activities and organized events for up to 300 participants. Additionally, residents have access to modular furniture made from recycled wood offcuts from the building.
TECHNOLOGY AND ENVIRONMENT
Wood Up is one of the first buildings in France to surpass the typical height limits for timber constructions. This innovative project serves as a demonstration that architecture can play a crucial role in the fight against climate change. As a building material, wood offers numerous environmental and economic benefits: it absorbs CO2 during its growth and retains this carbon throughout the building's lifespan. Furthermore, wood is a renewable resource when it comes from sustainably managed forests (such as those certified by PEFC or FSC).
From an energy perspective, wood requires minimal energy for harvesting, processing, and installation, while also bolstering the local economy by utilizing local resources and creating jobs that cannot be outsourced. Additionally, timber construction, often paired with prefabrication techniques, allows for quicker and more efficient completion of building projects.
STRUCTURE AND MATERIALS
The building's structure consists of several key components:
- A concrete base and infrastructure, from the ground floor to the first floor,
- A primary load-bearing framework composed of glulam posts and beams,
- A concrete bracing system, featuring a central core and wall elements,
- A secondary framework of glulam beams,
- Mixed wood and concrete floors. All the timber used in this project is sourced from France and transported via the Seine river. This selection is based on a carefully studied combination that considers the unique properties of each wood type and their specific roles within the structure. The interior posts are crafted from beech, a dense hardwood that provides excellent compression resistance, allowing for more efficient use of space. The interior beams are made from spruce, a softwood known for its superior bending strength compared to beech. Meanwhile, the exterior posts and encapsulation elements are constructed from Douglas fir, a softwood recognized for its enhanced resistance to humidity (Class 3). Additionally, all offcuts and remnants from the wooden elements have been repurposed to create furniture for the building's communal areas.
