Forestack transforms an abandoned public bath in Busan into a vertical ecological landscape that merges architecture, nature, and public space. The project reinterprets the existing structure through a strategy of minimal intervention, introducing layered programs including therapeutic gardens, social areas, and integrated vertical planting systems. Organized as a gradual vertical sequence, the design moves from grounded bath gardens to elevated rooftop greenery, framing architecture as a process of ecological and social healing. By prioritizing adaptive reuse and natural growth over time, the proposal creates a calm, restorative environment that reconnects users with nature while demonstrating a sensitive and technically grounded approach to regeneration.
The best presentation award 2025
Project title: Tranquilizing the Void
Author: Xavier Arés, Koh Noguchi, Juan Pablo Lopez Isabella, Spain
Tranquillizing the Void proposes a small-scale architectural intervention within the residual spaces of Kyoto's dense urban fabric, transforming overlooked gaps into places of retreat and reflection. Inspired by the Japanese concept of oku, the project creates a layered spatial experience through a lightweight timber pavilion that emphasizes depth, intimacy, and quietness. The design combines translucent polycarbonate panels, tatami interiors, and carefully framed roof openings that draw natural light into the space. Minimal yet precise, the structure offers a refined balance between simplicity and craftsmanship, presenting a replicable strategy for activating underused urban voids while fostering moments of calm within the city.
Highlighted Projects
Project title: GEM – Geological Museum and Scientific Research Center
Author: Vagia Dimara, Greece
The GEM project explores the relationship between geology and architecture through a museum and research center embedded within the geomorphological landscape of Grevena, Greece. Inspired by natural processes such as erosion and the formation of landforms, the design integrates the building into its terrain using a fragmented, layered composition that reflects the surrounding geological conditions. The program combines public exhibition spaces with private research facilities, organized to highlight both education and scientific study. Exterior courtyards and geological gardens extend the experience into the landscape, reinforcing a sensory connection to the site. Constructed with concrete, glass, and stone, the project creates a spatial narrative that guides visitors through a contemporary interpretation of the region's geological history.
Project title: Batumi 08.10.2021
Author: Shalva Makharadze, BRUT Architecture, Georgia
Batumi 08.10.2021 is conceived as both a residential structure and a memorial, responding to the tragic collapse of a Soviet-era building caused by unauthorized structural alterations. Designed in a raw Brutalist language, the project uses exposed concrete to express permanence, gravity, and accountability, transforming architecture into a vehicle for collective memory and social awareness. The façade is carved with voids that symbolize the lives lost, while integrated greenery introduces a narrative of renewal and resilience. A prominent red stair core marks the exact point of collapse, making circulation visible and emphasizing safety, transparency, and escape. More than a replacement building, the project acts as a civic statement, addressing structural negligence and advocating for responsibility in the built environment.
Project title: Unseen Museum
Author: Kelvin Goh Cher Kiang, Lim Zi Hong, DESIGN DRIVE, Singapore
The Unseen Museum is a conceptual proposal set within the Uyuni Salt Flats, exploring how reflection and visual disappearance can transform architecture into an extension of its environment. Conceived as a reflective cube, the building uses one-way mirror cladding to merge seamlessly with the sky and terrain, appearing invisible from a distance while revealing itself upon approach. Inside, a luminous, glass-lined interior guides visitors through exhibits on Uyuni's geological and cultural history, using reflection to create depth and immersion. Designed with a minimal footprint and heat-reducing materials, the project prioritizes environmental sensitivity while choreographing light, movement, and illusion to redefine the relationship between architecture and landscape.
Project title: Data Center in the Age of 'Datafication'
Author: Yicheng Ren, United States
This project reimagines a former industrial factory in Providence, Rhode Island, as a contemporary data center that challenges conventional, closed typologies by transforming it into a public and critical space. Rather than concealing digital infrastructure, the design introduces a linear promenade that deconstructs the existing industrial order and reconstructs it into a narrative sequence of spaces combining data functions with exhibition environments. Transparent server rooms, surveillance installations, and layered circulation systems reveal the mechanisms of data collection while questioning issues of privacy and control. Through material reuse and spatial openness, the project reframes the data center as an accessible institution that exposes, humanizes, and critiques the invisible systems shaping contemporary society.
Project title: Huailai Wine Culture Center
Author: Xinyi Wang, Australia
The Huailai Wine Culture Center reimagines a cultural complex as a landscape-driven composition, where architecture emerges from terrain rather than dominating it. Organized around a central water basin, the project brings together four programs—museum, cultural and retail spaces, expo hall, and hotel—into a cohesive ensemble connected by continuous circulation and undulating green roofs. These accessible "mini-mountains" shape microclimates, frame views toward vineyards and distant mountains, and create a sequence of public terraces and gathering spaces. Water acts as both a climatic moderator and civic stage, supporting year-round activities while reflecting the surrounding landscape. Through its integration of program, ecology, and public life, the project establishes a new identity for Huailai that blends terroir, culture, and everyday experience into a unified spatial narrative.
Project title: Al-Ula Villa
Author: Essamalden Mohamed Mohamed Abdo Alemam, Aishidha Rajeev, Nada Gamal Eissa Bakhit, Hind Altawi, Saudi Arabia
Al-Ula Villa draws inspiration from the sculpted sandstone formations of AlUla, translating geological processes into a contemporary residential architecture defined by carved volumes and layered massing. The design is composed of clustered cylindrical forms shaped through subtraction, creating courtyards, terraces, and openings that echo natural erosion patterns while allowing light and air to penetrate deep into the interior. A palette of earthy materials, including textured plaster and stone tones, reinforces the connection to the surrounding desert landscape. Internally, fluid spatial sequences unfold around central volumes and vertical connections, balancing openness and enclosure while framing views of the environment. The project reinterprets traditional desert architecture through a contemporary lens, creating a dwelling that feels both rooted in its context and shaped by time.
Project title: Edible Infrastructure: Re-stitching Urban Fabrics
Author: Xinwei Guo, United States
Edible Infrastructure transforms freeway-divided neighborhoods in West Oakland into a regenerative urban network that integrates mobility, agriculture, and community space. Built from recycled shipping containers and a laminated timber framework, the project creates a modular system of vertical farms, public programs, and elevated pedestrian and cycling paths that reconnect fragmented urban fabric. A layered "living canopy" provides shade, food production, and social gathering spaces, while the continuous circulation network promotes low-carbon mobility. By combining ecological systems with adaptive reuse, the design reframes infrastructure as a tool for social equity and environmental resilience, offering a scalable model for repairing urban divisions and activating underutilized spaces.
Project title: Endless Library
Author: Jianing Yang, United States
Endless Library reinterprets Frederick Kiesler's Endless House as a contemporary public building, translating primitive, non-rectilinear geometries into a fluid and continuous architectural language. The project organizes its program—exhibition spaces, reading rooms, and public amenities—within three sculptural volumes elevated above a porous ground plane, creating an open civic platform below. Circulation is structured around a central vertical spine, while interior spaces are shaped by curvature to promote openness, light, and visual continuity. Constructed with fiber-reinforced plastic and glass, the façade emphasizes smooth, continuous forms and diffuse daylight. By merging geometric experimentation with functional clarity, the project proposes a new library typology defined by spatial fluidity, public accessibility, and sculptural expression.
Project title: Shelters of Tomorrow
Author: Rabee S. R. Alashi, Saudi Arabia
Shelters of Tomorrow proposes a modular housing system for displaced communities in Bosaso, Somalia, designed to move beyond emergency relief toward long-term resilience and dignity. Rooted in Somali vernacular architecture, the project uses a flexible 4x4m unit that can expand incrementally and aggregate into diverse village-like clusters, supporting both individual households and communal life. Each dwelling combines enclosed rooms with semi-open spaces and private gardens, while shared areas emerge organically to host farming, markets, and social interaction. Built from locally sourced materials such as acacia wood, mud bricks, and palm leaves, the system emphasizes low-tech construction and adaptability, offering a scalable and culturally grounded model for sustainable community development.
