What Saga Space Architects does

SAGA Space Architects is a Copenhagen- and Hanoi-based multidisciplinary architecture and technology studio, founded in 2018 by Sebastian Aristotelis and Karl-Johan Sørensen, that designs and builds space habitats, Earth architecture, hardware products, and research prototypes for extreme environments. The space portfolio centers on human-centered analog habitats — LUNARK (Arctic-tested Moon analog, 2020), Rosenberg Space Habitat (2022), UHAB underwater habitat (Phase 3 targeting 2026), and FLEXHab (delivered to ESA's European Astronaut Centre in 2025) — supported by proprietary technology including the Circadian Light System (operating aboard the ISS for 1,140+ days), ODIN habitat operating system, Ravens environmental sensors, and Cyberdeck mission control. Earth architecture applies space-derived computational design, large-scale 3D printing, and biogenic fabrication to projects such as Skovsporet (Europe's largest 3D-printed housing development, 36 units), EcoNeo, Eden Villa (world's largest electrochromic glass dome), Mirador Pavilion, and Amaravati Spa.

The studio generates revenue primarily through bespoke professional services contracts — design and engineering projects, hardware development (including the ISS-deployed Circadian Light), and research-and-innovation partnerships under programmes such as ESA GSTP and Horizon Europe — supplemented by visualization services for external studios and SAGA Talks speaking engagements. Go-to-market is enterprise field sales targeting space agencies (ESA, NASA, DLR), defense and research institutions, commercial space partners (Starlab), housing developers, municipalities, and high-net-worth private clients, with an estimated ~20+ staff combining architecture, engineering, design, and software development alongside a 1,500 m² fabrication workshop.

Products and services

• FLEXHab A 28 m² analog habitat designed to train astronauts for Artemis missions at ESA's European Astronaut Centre in Cologne, Germany. Supports medium-to-long-duration analog missions for a crew of four, featuring circadian lighting, smart monitoring via ODIN, 3D-printed interior elements in upcycled waste wood, an airlock/hygiene room, sleeping cabins with acoustic panels, a laboratory with work desks and MCS communication hardware, and a galley area.
• UHAB Underwater Habitat An underwater habitat prototype for a modular, adaptable habitat deployable in extreme environments, from underwater research stations to lunar bases. The pilot phase tested a 1.5 m² habitat at 7 m depth in Copenhagen Harbour for 48 hours. A full-scale habitat (UHAB-3) targeting 2026 will support a crew of 4 for longer durations, serving as an astronaut training facility and marine research platform, integrating Ravens sensor packs and the ODIN habitat operating system.
• LUNARK Moon Habitat A deployable Moon habitat analog featuring a closed origami shell with rigid carbon fiber panels, algorithmically optimized for a measured 750% expansion ratio. Tested during a 60-day Arctic Greenland expedition with founders Sebastian Aristotelis and Karl-Johan Sørensen, enduring temperatures down to -30°C and hurricane-scale winds. Incorporates custom Circadian Light Panels to simulate Earth's 24-hour light cycle.
• Rosenberg Space Habitat A second analog Moon habitat designed, constructed, and installed in 9 months at Institut auf dem Rosenberg in Switzerland. A space-optimized structure with 2.5 floors for a crew of 2, featuring multi-functional floors and furniture, 3D-printed shell panels in UV-stabilized ABS polymer, sleeping pods with textile coverings, living quarters with touch dashboards, and the most sophisticated version of SAGA's circadian lights.
• Circadian Light System A dynamic lighting system designed to regulate astronauts' circadian rhythms in space habitats. The ISS Circadian Light Panel features three light faces emitting different wavelengths to promote alertness or induce sleepiness, automatically adjusting to the astronaut's planned sleep schedule. Evolved from deployments on LUNARK (2020) and Rosenberg (2022). Now operating aboard the ISS for 1,140+ days.
• Skovsporet Student Housing A student village in Holstebro, Denmark comprising 36 ground-level apartments, designed to become Europe's largest 3D-printed housing development.
