Mobile CLT Cabin | EarthboatJapans economic boom in the late 20th century led to the proliferation of leisure facilities such as ski resorts, golf courses, and fishing ponds. However, many of these sites have since fallen into disuse, presenting a challenge for contemporary architects seeking sustainable solutions for their revitalization. Earthboat V1, designed by PAN- PROJECTS, responds to this issue, offering a mobile, foundation-free cabin crafted from Cross-Laminated Timber (CLT). Earthboat transforms forgotten landscapes into functional retreats by integrating eco-conscious principles with hospitality.Earthboat V1 Technical InformationArchitects1-2: PAN- PROJECTSLocation: Various Sites Across JapanBuilding Function: Mobile Cabin, HotelArea: 20.5 m2 | 220.66 Sq.

By applying it to a compact 20.5m mobile cabin, the project demonstrates CLTs adaptability and its potential for small-scale construction.One of the defining aspects of Earthboat is its foundation-free, floating design, which minimizes land disruption and allows for seamless integration into diverse environments. Unlike traditional hospitality structures that require extensive groundwork, Earthboat preserves the natural terrain while ensuring flexibility in relocation.The interior is designed with functionality in mind, featuring modern amenities such as an integrated sauna. Its prefabricated nature ensures efficient construction, reducing waste and allowing for deployment across multiple locations.Earthboat V1 Contextual Adaptability & Regenerative ArchitectureEarthboat is an example of regenerative architecture, repurposing underused landscapes without imposing permanent structures. The project has been implemented across seven locations in Japan, with around 60 units completed or in progress. By activating dormant leisure spaces, Earthboat introduces new ways of engaging with nature, offering an alternative to outdated concrete facilities.Its mobility allows it to migrate to new locations as needed, ensuring continued usability. This approach aligns with the growing trend of eco-conscious travel, where guests seek immersive experiences without the ecological burden of permanent developments. Earthboat serves as a model for future adaptive reuse projects worldwide by preserving and revitalizing landscapes rather than altering them.Architectural ImplicationsEarthboat V1 is an architectural experiment that challenges the conventional norms of hospitality design. By proving the viability of CLT in small-scale applications, it sets a precedent for its broader adoption in Japan and beyond. Its modular, prefabricated approach suggests possibilities beyond leisure, including off-grid living, disaster relief housing, and remote workspaces.Nonetheless, Earthboat V1 offers a different approach to design, environmental regeneration, and hospitality. It is an invitation to rethink how architecture interacts with the land, demonstrating that temporary structures can impact how spaces are used and revitalized.Earthboat V1 PlansFloor Plan | PAN- PROJECTSSection | PAN- PROJECTSEarthboat V1 Image GalleryAbout PAN- PROJECTSPAN- PROJECTS is a London and Copenhagen-based architectural design studio founded by Yusuke Kinoshita and Kentaro Nishi. The firm is known for its conceptual approach to architecture, blending cultural narratives with innovative material applications. With a strong focus on temporary and adaptive architecture, PAN- PROJECTS explores how spaces can evolve with time and context, often working with timber and modular systems to create sustainable and impactful designs. Their work has been recognized internationally for its ability to challenge conventional architectural norms while fostering a deep connection between people, place, and materiality.Credits and Additional NotesStructural Engineer: ARSTRConstruction Type: Prefabricated, Foundation-Free StructurePrimary Material: Cross-Laminated Timber (CLT)
