在巴黎第三区的马雷区中心，雅克·穆萨菲尔完成了一座建于1970年代的建筑的改造，将其转变为一个混合用途的商业场所，包含办公室和公寓。
Inside Outside工作室 “阿姆斯特丹” 参与了这一项目，创造了一个10米高的幕帘立面。
重构高马雷的现代建筑
这座由Biro Fernier公司设计的10层商业建筑是法国战后30年经济繁荣时期的一个罕见例子。它由一个7层的钢筋混凝土框架和一个采用预应力混凝土技术建造的3层地下停车场组成——这一技术在当时是创新的——建筑内部有一个倒置的拱顶，支撑着城市街区中心的悬挂花园，屋顶则是一个带有6个天窗的曼萨德屋顶，整个结构均由模板混凝土构成。尽管这座建筑位于一个完全由受保护历史建筑组成的地标区，但当地当局 “ABF” 认为它没有遗产价值，从而促进了内部布局和外立面的改造。
中性和通用的结构
原建筑的主要优点在于其中性和通用的特性，像没有中间柱子的开放式楼层。正是这种对建筑结构的整体把握指导了我们的建筑选择，从内部元素 “楼梯、护栏、地面和天花板覆盖物” 的插入到外立面的设计，包括材料的选择和实施细节。因此，楼梯和护栏以及外立面被设计成借鉴锁匠工艺的特征，通常悬挂并与混凝土结构分离，以突出原有外壳与这些“借用”特征之间的承重关系。
一面高达12米的幕帘立面，呈现出一棵伟大的“葡萄牙月桂” “Prunus Lusitanica” 的轮廓，为Rue du Vertbois注入了新的活力。这一壮观的成果是Inside Outside “阿姆斯特丹” 与Moussafir Architectes密切合作的结果，外部幕帘覆盖了这座位于马雷区中心的建筑的立面。
纺织建筑已成为Inside Outside公司的标志，其灵活性常常立即改变内部和外部的空间。在这个项目中，遮阳幕帘延伸至玻璃和钢材立面的外部。这个由四个独立部分组成的幕帘在四个面向街道的楼层上展开。一方面，它的作用是过滤自然光和视线，同时为内部空间降温；另一方面，它与建筑的建筑风格对话，为立面的构成增添了最后的润色。
幕帘的波动运动可以在每层楼上控制，同时通过LED的隐蔽集成实现整个PVC网格表面的光效变化。圆形穿孔勾勒出树的轮廓，使网格对风具有透气性，同时将自然光的玩味光影投射到内部。整个建筑的五层上，幕帘以一种坚固的蓝灰色呈现出葡萄牙月桂的形象。幕帘通过集成传感器的电动系统开合。
公寓如办公室
与街道上的立面 “坡度为1.36米” 和花园侧的立面 “长10米且没有中间承重结构” 一样，柱梁系统的合理性使得单一用途建筑向混合用途建筑的转变成为可能，将住宅与办公室叠加在一起。我们决定暴露结构，促使我们不区分居住空间与办公室，并将公寓设计成像办公室一样。
现代主义原则与粗野主义美学
除了展示普通结构的多功能性外，我们的目标是强调建筑现代主义原则的相关性 “开放式平面、网格和面向北方的立面、南方的带窗带” 并通过增强其材料性来突出其粗野主义美学。
In the heart of the Marais, in the 3rd arrondissement of Paris, Jacques Moussafir has completed the rehabilitation of a building dating from the 1970s, transforming it into a mixed-use commercial location with offices and flats.
Inside Outside studio (Amsterdam) intervened in this operation to create a 10m curtain façade.
Restructuring a modern building in the Haut Marais
This 10-level commercial building designed in the 1970s by the Biro Fernier firm is a rare example in this sector of France’s 30-year post-war economic boom. It is comprised of a 7-story reinforced concrete framework on top of a 3-level underground car park built with prestressed concrete technology - innovative for the period - an inverted vault supporting a suspended garden in the heart of the city block and a Mansard roof profile with 6 lucarnes crowning the building, the entire structure being made of shuttered concrete. Although standing amidst a landmarked district composed entirely of protected historic buildings, local authorities (the ABF) determined that it had no heritage interest, thereby facilitating the transformation of both the interior distribution and its envelope.
A neutral and generic structure
Like open-plan floors without intermediate columns, the principal quality of the original construction resided in its neutral and generic character. It is this overall grasp of the building’s structure that guided our architectural choice, from the insertion of interior elements (staircases, guardrails, floor, and ceiling coverings) to the design of the envelope by way of the choice of materials and the details regarding their implementation. Thus, the staircases and guardrails, as well as the façades, were designed as features borrowed from locksmithing, most often suspended and dissociated from the concrete structure in order to highlight the loadbearing role of the original shell in relation to these “borrowed” features.
A façade curtain twelve meters in height with the silhouette of a great 'Prunus Lusitanica' (Portuguese laurel) gives new vitality to the Rue du Vertbois. The spectacular result of close collaboration between Inside Outside (Amsterdam) and Moussafir Architectes, the exterior curtain covers the façade of this building in the heart of the Marais.
Textile architecture has become the signature of the Inside Outside firm, its flexibility often immediately transforming both the interiors and exteriors. For this project, a shade curtain stretches across the exterior of the glass and steel façade. This curtain, comprised of four independent parts, unfolds over the four street-facing levels. On the one hand, its role is to filter natural light and views whilst also cooling interior spaces, on the other hand, it dialogues with the building’s architecture to put the finishing touches on the façade’s composition.
The curtain’s undulating movement can be controlled on each floor as well as the lighting effects across the entire surface of the PVC mesh thanks to the discrete integration of LEDs. Circular perforations define the outline of the tree, rendering the mesh permeable to the wind whilst also casting playful swathes of natural light into the interior. A solid blue-grey composes the image of the Portuguese laurel across all five of the building’s floors. The curtain opens and closes by means of a motorized system with integrated sensors.
Flats like offices
Like the façade on the street, which has a pitch of 1m36, and the façade on the garden, which is 10 meters long and has no intermediate load-bearing structure, the rationality of the pillar and beam system enabled the transition from a single-purpose to a mixed-use building superimposing housing with offices. Our decision to expose the structure provided the incentive to not differentiate the dwelling spaces from the offices and to design the flats like offices.
Modernist principles and brutalist aesthetic
In addition to demonstrating the multi-purpose aspect of an ordinary structure, our aim was to assert the relevance of the building’s modernist principles (open plans, grid and façade open to the north, ribbon windows to the south) and to highlight its brutalist aesthetic by enhancing its materiality.
