To stimulate students' potential for design innovation and cultivate imaginative and innovative design talents, the 2025 Tongji University International Construction Festival and the 2025 Fengyuzhu Plastic Hollow Board Building Design and Construction Competition will take place from June 7th to June 8th, 2025, at the College of Architecture and Urban Planning of Tongji University. Participating teams include 11 first-year student teams from the College of Architecture and Urban Planning, College of Design and Innovation, and College of Civil Engineering at Tongji University, as well as 19 first-year student teams from China’s architectural colleges, and 6 student teams from architectural colleges in the US, Europe, and Asia. In total, 260 teachers and students will collaborate to design and construct 36 plastic hollow panel buildings. 

The construction is scheduled for June 7, 2025 (Saturday), and the award ceremony will take place on June 8, 2025 (Sunday). The construction site is ABC Square at the College of Architecture and Urban Planning, Tongji University. Selected projects from this year's construction festival will be rebuilt in Fengxian District and Fuxing Island.

The Theme for the Construction Festival:

The ARK: Living Units in Interstellar Journey

In Pacific One, the concept of land ownership does not exist at all. All buildings are floating and their positions are uncertain... There are also a large number of vagrants in the city. They don't even have shanties. All their belongings are placed in a large net bag to prevent them from floating away. They live while floating together with the net bag... Metal parts, plastic utensils, and electronic waste collide with each other in the net bag, making a chaotic jangling sound like wind chimes, creating an absurd contrast with the deathly silence of this city of eternal night.

Most of the buildings in the city are simple shanties, made of discarded materials into cubes or spheres with fully open windows (doors) on all six sides... Under the endless lights powered by nuclear batteries, the net bags carried by vagrants sway during collisions. The fragments of industrial remnants from the old world make soft noises, like the wind chimes at a space funeral, playing a mechanical elegy for this abandoned city.

—— The Three-Body Problem III: Death's End

Architecture in science fiction is a symbiosis of technology and imagination, commonly found in literary works or artistic creations. In the Pacific One ruins depicted in The Three-Body Problem, the alienated relationship between architecture, sound, and space breaks humanity's obsession with fixed space. In a fragile yet rustling environment, the journey of architecture across time and space is boundless and fluid. How can humans redefine habitation in interstellar travel? When architecture is constrained by special requirements for materials and construction, can it balance safety, practicality, and comfort to achieve the buildability of science fiction architecture? A real spatial revolution is coming, and humans on interstellar journeys have already sent us the voice of the future.

Please start from the theme of Future to interpret and imagine, block the impact of noise in space, and carry out human shelter design and construction practices with this as the goal. The building needs to have two entrances and exits and form a good flow organization relationship with the internal and external spaces.

The year 2025 marks the 17th time that the Construction Festival will be held at the College of Architecture and Urban Planning of Tongji University. We warmly welcome all old and new friends to reunite at Tongji University!
