Shanghai studio Archi-Union used differently sized bricks to make waves across the exterior of this restaurant and members’ club at a cultural heritage park in Chengdu, China (+ slideshow).

The architects used an algorithm to specify nine different brick types, which were laid by hand to create the wave-like texture across each wall.

Sloping roofs visually divide the longitudinal building into separate blocks and their curving shapes were designed by Archi-Union to reference mountains and rivers, as well as a typical form in Chinese architecture.

“The Lan Xi Curtilage is an interpretation of traditional Chinese architecture through the language of digital fabrication methods,” Archi-Union’s Crisie Yuan told Dezeen.

The restaurant and private club are positioned on opposite sides of a central courtyard, where pathways divide the lawn and dictate routes towards different rooms.

The Lan Xi Curtilage is located at the International Intangible Cultural Heritage Park, which plays host to a biennial festival dedicated to language, music, dance, storytelling, carnivals and rituals.

Earlier this year Archi-Union also completed a teahouse and library with twisted concrete walls.

Here’s some more information from Archi-Union:


The Lan Xi Curtilage

The spatial layout of this project represents a new interpretation of a traditional South China Garden. The multiple layouts of the longitudinal residence and courtyard reflect a hierarchical and multi-dimensional spatial pattern of traditional gardens. The silhouettes of the building’s roof embody rolling mountains and rivers, and also function as metaphor of the traditional Chinese sloping roof culture.

The design of the ripple wall derived from a digital interpretation of water, a flexible yet natural conception. We developed an algorithm that mimicked the transient behavior of water, which could be frozen in time allowing a literal architectural expression of its transient behavior. We adapted this algorithm to process a traditional building material, blue bricks, in a staggered joint pattern, in the same way as it produced a surface before, creating a bonded brick pattern with the intrinsic dynamics of water, and providing a light and transparent effect as well as structural walls.

The design focuses on developing an artistic pattern as well as on creating a feasible fabrication pattern. As a robotic arm was not available to lay the bricks automatically due to financial constraints, the masonry had to be completed manually in order to match the rigorous schedule of the three month construction period. Five kinds of brick joint template were devised and the joint gradient was achieved through the permutation and classification of the five template values, which were translated to a simple brick-laying schedule. The finished building is testament that light and shadow playing across the façade embody the dynamic effects of water. A careful combination of digital design and lo-tec fabrication to actualize digital fabrication exactly reflects the combination of digital technologies and local materials and fabrication.

Tea House by Archi-Union

Concrete walls twist up through the interior of this tea house and library that Shanghai architects Archi-Union have constructed in the backyard of their studio.

Tea House by Archi-Union

Constructed from timber-formed concrete, the two-storey building has a glass facade.

A triangular first-floor balcony projects from this facade and wraps around the branches of an existing tree.

The contorted concrete walls inside the building conceal a lounge and reading room behind the ground-floor tea room, plus a staircase leading to the library above.

Here’s some more from the architects:


Tea House, J-Office

The Tea House, located in the backyard of Archi-Union’s J-office, is constructed from the salvaged parts of the original warehouse’s collapsed roof. The site was extremely constricted with walls on three sides, and with only one side facing towards an open space that contains a pool. The space was further restricted by a mature tree. The design tries to embody harmony by integrating enclosure and openness, delightful space and logical construction and other complicated relations. This building reacts to the site’s environment; the plan layout is a logically obscure quadrilateral, thus maximizing the amount of space. It is divided into three parts. A covered public area is formed towards the open space with the pool, with an enclosed tea house at ground level and library on the first floor where a small triangular balcony extends around the existing tree. Other more private spaces exist such as a lounge, reading room and service room which are arranged towards the rear of the building; a delightful transitional space was created to connect the public space and the private spaces.

The transitional space was designed around a twisted nonlinear hexahedron staircase, which connects the functional spaces. The stair resolves the vertical transportation issue from the tea house and the library and provides an inner courtyard near the reading room for viewing the existing tree. The space was designed to bring a new experience to an ordinary functional space. Linear space suddenly changes into an expressive form, surging from the tea house then transforming into a tranquil space for the library on the floor above, making the reading room a special place to sit.

The volume is a three-dimensional irregular shape which is impossible to be understood through plans. The twisting shape was designed by scripting in Grasshopper an algorithmic plug-in for Rhino. However such a shape is difficult to translate into quantifiable information for guiding construction. The constraints of manual construction obliged us to invent solutions at the time of construction to realize the advanced digital design with local low-tech construction techniques. Firstly we abstracted the structural skeleton which was subsequently scanned with digital software. This curved shape was then recalculated through interlacing straight lines; these lines were then formed into ruled surfaces filling the void. The spacing was set to the dimension of timber, thus the digital ‘setting out’ could be easily translated into a manually constructible shape.

A 1:1 timber framework was produced by following the same logic as the digital model; a subdivided timber shuttering covered this framework to create a curved formwork. The formwork was built through a series of upper and lower layers according to the construction sequence. The casting was almost the same as ordinary concrete casting, reinforced with re-bars following the straight lines of the ruled surface. Concrete casting after the reinforced bar was completed by manual labor and the final physical effect was achieved. The traces of the timber formwork remained imprinted on the poured concrete after construction, with quality defects such as bubbles, adhesive failures and re-bar exposure present due to the manual construction – defects, however, that are obscured by the unique curved shape. Although there are errors of in the formwork, planning and manual casting the combination of digital design and low-tech manual construction provided a great opportunity to study the possibilities of digital architecture.
