The Eco-Aquaponic House by Michael Jantzen is a public botanical garden exhibit designed for aquaponic food production. The structure grows fish and plants through a closed-loop system, where fish waste moves through the surrounding plant roots as natural fertilizer. The plants filter the water before it returns to the central cylindrical fish tank, allowing the cycle to repeat with minimal outside input.
The greenhouse uses six rotating sections around a central pivot point. Two insulated panels help retain heat during cold nights, two shade screens protect plants on hot days, and two glass sections open for outside air. Heat-retention tubes around the stationary base absorb solar energy during the day and release it at night. A sun-tracking solar cell array sits on top and supplies most of the structure’s electrical needs, including the lamp above the fish tank.

The Eco-Aquaponic House Uses Rotating Sections and Solar Power
Trend Themes
-
Closed-loop Aquaponic Systems — A tightly coupled fish-plant nutrient cycle that minimizes external inputs enables year-round, resource-efficient protein and vegetable production in dense settings.
-
Modular Rotating Greenhouse Architecture — Rotating segmented shells around a central spine create dynamic microclimates that optimize light, shading, and ventilation for diverse crop zones within a single footprint.
-
Integrated Solar Thermal-energy Storage — Daytime solar heat capture with embedded thermal buffers that release warmth at night reduces dependence on external heating and smooths energy demand for controlled-environment agriculture.
Industry Implications
-
Urban Agriculture and Food Production — Dense-city food systems that combine aquaculture and horticulture in compact, low-input facilities could decentralize supply chains and shorten farm-to-fork timelines.
-
Architectural Design and Prefab Construction — Prefabricated rotating modules and adaptive façade elements present new possibilities for adaptive, climate-responsive buildings that integrate living systems.
-
Renewable Energy and Microgrid Systems — Localized solar arrays paired with thermal storage and small-scale electrical distribution can enable autonomous energy profiles for off-grid or resilience-focused installations.
