Yi Jing Yuan multi-function hall was built in the Xijiao State Guest Hotel in Shanghai, which occupies a broad, beautiful environment with lush trees. Since its completion in 1960, as Shanghai’s largest and highest ranking of the National Guest House, Xijiao State Guest Hotel has received many domestic and foreign dignitaries including Chairman Mao, Deng Xiaoping, Queen Elizabeth II and President Obama.

2016年，加拿大自然资源部、bc省林业厅与西郊宾馆所属的东湖集团关于进一步推动木结构发展达成协议，并将规划中的西郊宾馆意境园多功能厅作为实践案例，尝试木结构建筑的建造、应用与推广。经由加拿大木业协会与东湖集团前期选址、讨论及调研，推荐上海绿建建筑装饰设计有限公司负责该项目建筑设计，并由加拿大木业协会提供结构设计、现场监督等多方面支持。总部位于温哥华的Equilibrium Consulting Inc.也被聘请为结构计算和连接细节提供建议。

In 2016, the Ministry of Natural Resources of Canada, the BC Forestry Department of Canada and the Donghu Group who owns the Xijiao Hotel reached an agreement on further promoting the development of wood structure, and chose the planned Yi Jing Yuan multi-function hall as a practical case, for the application and promotion of wood structure building. Canada Wood worked together with Donghu Group, the project owner on the site selection, etc., and recommended Green-A Architecture & Decoration Design Co., Ltd. as architectural design company of the project. Canada Wood also provided the structural design and on-site supervision to ensure the delivery of construction quality. Equilibrium Consulting Inc. based in Vancouver was also hired to provide recommendations for structural calculations and connection details.
Located on the east side of the lake embraced by dense trees, the building with elegant and private setting offers hotel guests with dining, meeting and event space. The project is a single-storey glulam wood structure building, with a modest and humble profile, while adopting a delicate and rich interior space, makes it a perfect fit into the surrounding. The offsite prefabrication of wood structure components allows the onsite construction to be completed in an efficient and fast manner and caused minimum damage to the site land and surrounding landscapes. By using Wood, the ecological materials, the natural, green and sustainable development of the concept of construction has really been realized.

Yi Jing Yuan multi-function hall has a total construction area of approximately 857 square meters. The main function is to serve the hotel guests as the dining and meeting place. The architectural form simulates the attitude of tree growth. The structure columns and the triangular roof frame are naturally handed over and integrated, and the columns are staggered to form a three-dimensional spatial structure, which make the space more charming and interesting. The roof shape is composed by several equal-size folded plates staggered with each other, in clear geometric logic, to create a concise and dynamic indoor space, with a well-organized order, while providing the traditional simplicity and elegant charm. The skylights brighten the space despite the unfavorable lighting condition caused by its close distance to the surrounding tall woods. Sunny reflection beams casted from the skylights creates dynamic illuminations that boosts the stunning architectural features.

With a limited construction budget, the building has created a wonderful space and fascinating form, fully reflecting the natural, warm texture of the wood structure, as well as the aesthetic sense of geometry and mechanics. The interior finishing with wood reinforces the touch of natural beauty and design versatility. The wood grille backdrop represents the natural imagery of mountains that has long been read as a metaphor for the individual’s values and beliefs of unity of nature and human in Chinese philosophy.
The entire building uses about 212 cubic meters of wood, all of which are imported timber from Canada, with a total potential carbon reduction of about 557 metric tons. Among them, roofs and infill walls use SPF (No.2) about 57.81 cubic meters, increasing the overall building insulation and energy efficiency performance. The main structure frame uses 108.57 cubic meters of Douglas Fir, the structural grade, providing high strength and beautiful texture, which increases the aesthetics of the building space while ensuring the safety of the structure. The ceiling and wall decorations use 42.68 cubic meters of Hemlock with fine texture.

Design of this building began in December 2016 and construction started in March 2018 and finished in October 2018. Throughout the design and construction process, the structural engineers from Canada Wood provided active and effective assistance in cost consulting, structural calculation, detail design, on-site quality control, etc., to get the successful completion of the building. While the 2018 China International Import Expo was held in Shanghai, the building was selected as one of the main reception and banquet venues.
