Nature House, or Naturhus, refers to a Swedish architectural concept where a living space is encased within a large greenhouse structure. This design leverages passive solar heating for energy efficiency and year-round food production.
Core Concept
A Naturhus integrates a traditional home inside a greenhouse envelope, creating a temperate microclimate similar to southern Europe even in cold northern settings like Sweden. Residents benefit from natural warmth, abundant light, and fresh produce grown in surrounding plant beds.
Key Benefits
- Energy Savings: Solar gain reduces heating needs, with some models achieving near-zero operational carbon.
- Food Production: 30-80m² of growing space per dwelling supports organic fruits, vegetables, and herbs, minimizing food miles.
- Health and Lifestyle: Improved air quality, biophilic design, and communal areas promote activity and community living.
Real-World Examples
- Rosenlund Naturhus (Sweden): A private home south of Vadstena with an ecosystem for year-round gardening.
- Uppgrenna Naturhus: Features plant beds and terraces overlooking Lake Vättern, mimicking a Mediterranean climate.
- Findhorn Proposal (Scotland): Multi-dwelling greenhouse with rainwater harvesting, composting toilets, and greywater recycling for sustainability.
Sustainability Features
These homes often include rainwater collection, wastewater purification via plant beds, and low-embodied-carbon materials. They avoid municipal sewers by creating closed-loop systems, ideal for off-grid or eco-communities.
