总部小酒馆与社交咖啡馆,加拿大 / blanchette archi.design
加拿大蒙特利尔,2026年2月4日——blanchette archi.design 公布了 Siège Social 小酒馆与 Café Social 的室内设计项目。该项目位于加拿大隆格伊西圣查尔斯街1111号(1111 Saint-Charles Street West)的一层。项目由 Groupe Mercille 委托、PR Desjardins 承建。这个全新的复合型空间在原有办公塔楼大堂的基础上进行延展与转化,并以审慎的方式重新诠释了20世纪60至70年代企业办公环境的建筑与美学语汇。该项目被构想为对原有后现代风格大堂的自然延续,通过重新审视那个时代典型的形式严谨性与理性特质,将其转译为一种当代、温暖且友好的空间体验。作为咖啡馆、小酒馆与社交空间的结合体,这一场所既扎根于其办公环境语境之中,也为工作场所引入了一种新的使用文化。
Montreal, Canada, 2026-02-04 – blanchette archi.design unveils the Siège Social bistro and Café Social, an interior design project located on the ground floor of 1111 Saint-Charles Street West in Longueuil. Commissioned by Groupe Mercille, and carried out by PR Desjardins, this new hybrid space extends and transforms the experience of the office tower’s existing lobby, toughtfully reinterpreting the architectural and aesthetic codes of corporate environments from the 1960s and 1970s. Conceived as a natural extension of the postmodern lobby, the project revisits the formal strictness and rationality characteristic of that era, translating them into a contemporary, warm, and welcoming experience. A cross between a café, a bistro, and a social space, the venue is anchored in its tertiary context, while offering a new culture of uses within the workplace.

项目面积约为2300平方英尺,空间布局围绕两个既独立又互补的功能领域展开。Café Social 位于公共走廊的延续位置,作为一个充满活力且易于进入的过渡空间,在一天之中始终保持着活跃的氛围。Siège Social 小酒馆则被设想为社区中的一个非正式“总部”,通过开敞的界面与露台及前庭相连,鼓励用餐、会面与聚会等多种社交活动。项目通过清晰而统一的材料主题保持整体的一致性:哑光白色方形陶瓷砖被广泛应用于垂直界面以及定制家具之中。这种材料灵感来自既有大堂中的图案语言,并在项目中成为一种具有识别性的结构性母题。一面点缀着玻璃开口的胡桃木墙体在咖啡区与小酒馆之间过滤光线,形成一种轻盈而半透明的分隔,使两个空间始终保持视觉上的交流。
Spanning an area of approximately 2,300 square feet, the layout is organized around two distinct and complementary worlds. The Café Social, located in continuity with the common corridor, acts as a lively and accessible transitional space, bustling with activity throughout the day. The Siège Social bistro, designed as an informal ‘head office’ for the neighbourhood, opens generously onto the terrace and forecourt, encouraging meals, meetings, and gatherings. A strong material theme ensures the project’s coherence: square white ceramic tiles with a matte finish, used on both vertical surfaces and built-in furniture. Inspired by the patterns in the existing lobby, this materiality becomes an identifying and structuring motif. A walnut wall punctuated with glass openings filters the light between the café and the bistro, creating a diaphanous separation that maintains a constant visual dialogue between the spaces.

两个空间的氛围通过对材料与色彩的精确运用加以区分。咖啡区采用洞石、芥末色调以及深色木饰面,而小酒馆则使用陶土色、深绿色、浅色木材与整合式绿植,形成一种包裹感更强的空间氛围。灵感来源于20世纪60至70年代现代主义室内空间的色彩体系,这一配色被以当代、克制且具有时间感的方式重新演绎。照明在空间身份塑造中发挥着核心作用。通过整合于小酒馆天花中的 dim-to-warm 调光系统,空间氛围能够在一天之中从清晨到夜晚不断变化。悬吊天花的设计灵感来自办公环境中的垂直百叶窗,这一元素为室内空间引入了运动感、节奏与层次,将原本功能性的参考转化为一种更具感知性的空间体验。对于 Groupe Mercille 而言,该项目不仅仅是办公塔楼的配套设施,更是其推动区域更新的重要举措之一。项目被设想为一个向城市开放的新目的地,Bistro Siège Social 通过与周边使用者及邻近大学社区建立联系,为这一正在转型中的片区注入活力。
The atmospheres are distinguished by precise work on materials and colours. The café features travertine, mustard tones, and dark wood finishes, while the bistro adopts an enveloping palette of terracotta, deep greens, light wood, and integrated vegetation. Inspired by the modernist interiors of the 1960s and 1970s, the colour palette has been reinterpreted in a contemporary, understated, and timeless style. Lighting plays a central role in the identity of the space, allowing the atmosphere to evolve from morning to evening thanks to a dim-to-warm system integrated into the bistro’s ceiling. Inspired by the vertical blinds found in office environments, this suspended ceiling introduces movement, rhythm, and depth, transforming a functional reference into an attentive spatial experience. For Groupe Mercille, this project is part of a clear desire to contribute to the revitalization of a neighbourhood undergoing transformation, beyond the office tower itself. Designed as a new destination open to the outside world, the Bistro Siège Social contributes to the dynamism of this redevelopment hub, engaging with users in the area and the neighbouring university community.
