Ceramic Constellation Pavilion

Saturday, August 12th, 2017

I am very happy to share the recent outcome of our spring activities in the Robotic Fabrication Lab at HKU. The project entitled “Ceramic Constellation Pavilion – Spatial shifts through robotically fabricated terracotta bricks” represents the first research work in the newly formed collaboration between Sino Group and the Robotic Fabrication Lab.

The Pavilion, which was guided by Christian J. Lange, Donn Holohan and Holger Kehne was built by students utilizing robotic technology. The research initiative that supports arts, cultures, and technology is intended to foster cultural awareness of new technologies for the built environment.

In a context that has been largely shaped by standardization and mass production, the project seeks to overcome the constraints of today’s architectural production through the introduction of a structure made entirely of non-standard components.

This inaugural workshop of the “Sino Group Robotic Architecture Series” utilized terracotta clay to test the possibilities and limits within robotic fabrication and to revitalize a material system that has a significant tradition in Asia.

Departing from traditional brick bonds, the 3.8m tall project articulates a load-bearing composite structure with timber – where each of the nearly 2000 3d printed terracotta bricks is unique and different, enabling varying degrees of transparency, morphological shifts, and new experiences.

Around 700 kg of raw terracotta clay was printed over a period of 3 weeks into individual bricks that were then fired at 1025 degrees Celsius. With 2-3 minutes average printing time for each brick, the pavilion is one of the first of its kind in the world that incorporates this specific material system.

All components were fabricated with the equipment in the newly fitted Robotics Lab at HKU’s Faculty of Architecture and assembled during a ten-day workshop by students from the Department of Architecture.

The project was recently on show in the North Atrium of Olympian City, West Kowloon and will find its new home soon on the campus of the University of Hong Kong.

Final outcomes of Fall M.Arch I studio @ HKU

Friday, January 6th, 2017

At last, we can show some photos of the final outcomes of the latest studio taught by Christian J. Lange at The University of Hong Kong. The M.Arch I studio entitled “Elements: Robotic Interventions 0.2 – Towards new territories in Architecture” had two main objectives. On the one hand it was a hands-on investigation on how we as architects can generate new technologies, material systems and craftsmanship with the aid of the robot, and on the other hand, the studio looked in how we can apply those for the development of architectural elements such as the column the roof and the wall.

Students eventually built three medium scale prototypes that were based on three different traditional timber construction techniques. The first being the “Dou Gong” bracketing system, which usually is the structural network that joins columns to the frame of the roof in traditional Chinese architecture. The second being the reciprocal frame structures that can be found in the timber woven-arch bridges in the Fujian and Zhejiang provinces. And the third being the “Luban Lock” or the so-called “Chidori system” a design concept derived from old Japanese/ Chinese toys, and that elegantly produces a six-legged hidden joint.

Robotic Fabrication Lab @ HKU

Sunday, October 30th, 2016

For the past year Christian J. Lange has been working on the set up of the new robotics lab at the Faculty of Architecture at The University of Hong Kong. The lab was recently installed and consists of two ABB industrial robots, a rotational table and various end-effectors.

In an environment with rapidly growing cities, the robotic fabrication lab has its emphasis on the discovery of new methods, techniques and material assembly systems that have a meaningful and sustainable impact on the high-density build environment in the context of Hong Kong and Asia.

Currently Lange is teaching a March I studio focusing on the opportunities of robotic fabrication in traditional timber construction techniques that are specific to the Asian context. Below are some photos of the recent midterm presentation.

Reciprocal Timber Structures – outcomes of recent Robotic Fabrication workshop

Monday, August 15th, 2016

We are pleased to show some photos of the outcomes of the recent Robotic Fabrication Workshop. The workshop took place during late June 2016 at the University of Hong Kong and was led by Christian J. Lange and Donn Holohan. The project took on the typology of the tower as a point of departure to study the potential of low energy timber construction systems in conjunction with robotic fabrication.

Robotics in Architecture is a relatively young subject within contemporary design practice. At the Faculty of Architecture we are currently building up a Research Lab that will be dedicated to this new research field. In an environment with rapidly growing cities, the lab will have its emphasis on the discovery of new methods, techniques and material assembly systems that have a meaningful and sustainable impact on Architecture and the context of Hong Kong and the PRD.

The summer workshop “Robotic Intervention” will focus on traditional techniques of timber construction and will be a first test for a novel production method with robotic aid. Participants are invited to investigate on the relationship between material, geometry, computation and robotic fabrication through the design and making of a prototypical structure.

The workshop comprises of a research component on traditional timber material systems, a series of exercises on computational design and robotic fabrication techniques and will culminate in the construction of a 1:1 scale architectural intervention. The workshop will not only increase the student’s architectural skillset to build a structure in real scale, it primarily aims to open up the student’s understanding of the emerging creative uses of Robotics in Architecture.

– Workshop on Robotics in Architecture.
– Research on traditional timber construction systems
– Computational workshop on component based assembly structures.
– Fabrication and installation of a 1:1 scale intervention at HKU.

Results of Smart Geometry workshop on display at the Chinese University of Hong Kong

Thursday, July 24th, 2014

Christian J. Lange of Rocker-Lange Architects teamed up with Jason Carlow, Assistant Professor at HKU, Ramon van der Heijden and Alan Tai from Front Inc Hong Kong, and Gustav Fagerström from Buro Happold New York for this years Smart Geometry Conference in Hong Kong.

The results of the workshop entitled HK_SmarTowers were on display during the two day conference on July 18th & 19th at the Chinese University of Hong Kong. The project that was developed during the four days looked at how data informs tower massing strategies, structure and organization. Addressing the issue of repetition, standardization, mass production and customization the project utilized intelligent digital design systems to arrive at a set of unique tower structures that were based on different figure ground strategies and ultimately built with a ready made system of kit of parts.

Thanks a lot to all Cluster Collaborators for the great work: Marco Juliani, Megan Ng, Oliver Thomas, Piotr Baszynski, Luca Maccarinelli, Binsun Hu, Amos Chan, Vincent Ip, Albert Lo, Riyad Joucka, Mariane de Souza, Alison Li, Xinliu Huang

Rocker-Lange wins honorable mention

Saturday, June 1st, 2013

Rocker-Lange Architects were awarded a honorable mention in the international design competition for a new bench design for the Kowloon East district in Hong Kong. The competition was held in conjunction with the 13th Venice Biennale International Architecture Exhibition, Hong Kong Response Exhibition.

Rocker Lange Architects, Urban Adapter HK 2.0, Christian J. Lange, Ingeborg M. Rocker, urban furniture

The redevelopment of Kowloon East will have a diverse array of spatial conditions, from new, open public waterfront parks to tightly planned former industrial areas. Traditionally urban furniture consists of repeatable standardized elements while being installed in various conditions. The problem with repeatable elements is that they don’t adapt necessarily very well to the specificity of each site condition. The key concept of the “Urban Adapter HK 2.0” project is to establish a system that can address the explicit conditions of each site, and to blend each bench with a variety of programs. The specific design methodology and the computer aided construction and assembly process allows making every bench unique while creating a distinctive family of urban street furniture that creates a merging identity for Kowloon East.

This project with its unique user surfaces will have the capacity to place the user in a new position with the urban reality and its ecologies as much it may reposition the urban reality all together. Not only will it improve the quality of the public realm, it will also establish a new framework for use and for seeing and being seen in the urban streetscape of Kowloon East.

The material for this street furniture will be wooden slats making it a positive sustainable contribution. The finish of the bench is made of climbing rope or rubber band finish. Each bench will have a distinct color out of a specific color family making each bench identifiable. The wooden slats are CNC cut, making sure that each bench can be precisely assembled.
