Ceramic Constellation Pavilion

August 12th, 2017 by admin

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.

The robots are taking over … and building Hong Kong’s future

June 15th, 2017 by admin

Very happy to be included in a recent article on robotics in architecture in the South China Morning Post. The article discusses the current outlook of this technology in Hong Kong and was written by Ernest Kao. It’s actually a very good read. Enjoy!

Ceramic Constellation | Robotic Fabrication & Building Workshop

May 2nd, 2017 by admin

Christian J. Lange will be teaching again a Summer workshop on Robotic Fabrication in Architecture at The University of Hong Kong. The program will take place from June 5th through June 16th 2017.

Ceramic Constellation, Robotic Fabrication, 3d printed bricks

This year’s summer workshop “Ceramic Constellation” is sponsored by SINO GROUP and is based on the current research undertaken in the lab that focuses on ceramic fabrication through the aid of the robot. Ceramics have a long history in Architecture, especially in the context of China. However, in today’s standardized world, the richness of the material is nearly gone. With few exceptions in contemporary Chinese Architecture, it seems that the materials’ remaining territory in the building industry diminished to the use of dull homogeneous façade tiles. Therefore the intention of this workshop is to test the potential of the material in todays advanced technological world and to build a large-scale pavilion that will be installed on a site in the Olympian City shopping mall in Kowloon.

The workshop comprises of a series of exercises on tectonics, computational design and robotic fabrication techniques and will culminate in the construction of a 1:1 large-scale architectural intervention. The workshop will expand the student’s skillset and understanding through building an innovative structure in real scale, and aims to open up the student’s understanding of the emerging creative uses of Robotics in Architecture.

– Workshop on Robotics in Architecture.
– Computational workshop on component based assembly structures.
– Fabrication of components
– Construction and Installation of a 1:1 scale intervention.

Set Up:
Hardware: 1 x ABB 6700 1 x ABB IRB 1600
Software: Rhino, Grasshopper, HAL

Up to 20 students of the Department of Architecture, HKU, led by
Christian J. Lange
Donn Holohan
Holger Kehne

The program will take place from June 5th through June 16th 2017.

Information session:
To give students a better understanding of the workshop we will have a lunch-time information session on May 12th in room 419 1:00pm.

The program is open to all fulltime students registered in the BAAS, March, MLA, MPhil and PHD programs in the Department of Architecture. Interested applicants should send a one page CV to the BAAS secretary Angela Ting by May 19th.





H-Residence on HGTV Asia

March 29th, 2017 by admin

Rocker-Lange Architects is happy to share the recent feature of their H-residence project on HGTV-Asia’s Small Spaces section. In this short film host James Koh is interviewing Christian J. Lange and his wife Alice to get some insides of the concepts behind this apartment renovation in Hong Kong. The video is now online on Youtube. Check it out.

Final outcomes of Fall M.Arch I studio @ HKU

January 6th, 2017 by admin

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

October 30th, 2016 by admin

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

August 15th, 2016 by admin

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.

H | Residence in SCMP’s Post Magazine

We are delighted to share the recent coverage of our H | Residence project in South China Morning Post’s Magazine. Journalist Adele Brunner writes “German who lectures at University of Hong Kong turned a flat in a walk-up building in Sai Ying Pun into a clutter-free retreat, with picture windows for a ‘glass house’ feel that lets in some of the bustle of the streets”.
