Near the rainy coast of Gothenburg, a Swedish couple—Sylvia, who works for the military, and Johan, an IT professional—set out to build more than a house. They sought a greenhouse eco-home design that worked in harmony with nature, rather than resisting it.
“We have been thinking about building a house, but we wanted to do something more than just building a house. We wanted it to have some kind of purpose,” Sylvia explained.
Sylvia grew up on a farm, while Johan grew up in the city. Their combined backgrounds shaped the home’s unique design: a two-story wooden family house fully enclosed within a 1,900-square-foot greenhouse.
The glass shell moderates the coastal climate, extends the growing season, and allows Sylvia to cultivate plants she never imagined possible in Sweden, including grapes and peaches.
As Sylvia put it, “Why am I fighting nature? This is part of us in like every way. Why can’t I work with it in some ways at least?”
This question became the guiding principle behind Naturhus Torpadal: a home that cooperates with natural systems rather than fighting them.
Life inside a greenhouse eco home design
Stepping inside the home feels like entering a warm, sun-filled garden rather than a typical Scandinavian house.
The greenhouse envelope acts as a climate buffer, capturing solar warmth and maintaining a steady indoor air temperature.
Even during chilly winter months, sunlight streaming through the glass can heat the greenhouse to 20–25°C, allowing the children to play in shorts while it rains outside.
The space between the inner wooden house and the greenhouse provides an “extra room of nature.”
It’s a place for gardening, exercise, or just enjoying light and air. Swings and rings hang from the structure, creating an indoor playground that seamlessly merges with the outdoors.
Within this glass sanctuary, Sylvia cultivates a diverse array of vegetables, fruits, and herbs throughout the year.
Tomatoes, Bulgarian peppers, grapes, kiwi, and even experimental crops thrive thanks to the controlled environment and nutrient-rich soil beds.
Building a home with purpose
When they began, Sylvia and Johan imagined a practical family home. However, their vision evolved into a greenhouse eco-home design that seamlessly combined sustainability, comfort, and beauty.
The inner wooden house covers about 1,000 square feet. It is built with laminated wood, thick insulation, and thoughtful passive-house principles.
The couple divided the house into functional zones. One section is “dirty” for laundry, showers, and training gear.
The other is “clean,” where the family relaxes, cooks, and spends most of their time.
Sight lines were carefully planned so that every window frames nature, while private areas, such as bathrooms, remain discreet.
The layout also maintains a daily flow efficiency—kids can transition smoothly from play to homework to meals without disruption.
The construction process involved close collaboration with architects and engineers to ensure every element had purpose, from laminated beams to glass panels.
Even the existing basement was reused as a solar pump house and storage for the rainwater system.
Greenhouse eco home design’s functional spaces: Kitchen, bedrooms, and bathroom
The kitchen sits on the ground floor, opening into the main living and dining area.
Counters are wide for food prep, and the layout allows sunlight and greenhouse views to fill the space.
Sylvia can easily prepare meals using fresh produce harvested just steps away.
The living and dining areas are open and flexible, allowing children to play indoors while adults cook or work.
The greenhouse acts as a natural buffer, keeping the home warm and quiet during winter.
Upstairs, the bedrooms are simple, bright, and warm. Large windows face the greenhouse, allowing sunlight to enter and minimizing the need for additional heating.
Each room is roughly the same size, creating a democratic space for the children. The main bedroom overlooks the greenhouse garden, offering a peaceful view of their indoor ecosystem.
The bathroom supports the home’s eco-friendly ethos. A modern shower and efficient fixtures are connected to the closed-loop water system.
All wastewater—kitchen, bathroom, and even toilet—is filtered through natural soil beds and reused to nourish plants in the greenhouse.
Despite its sustainable design, the space feels light, airy, and comfortable.
How closed-loop systems make the home self-sustaining
A significant feature of this greenhouse eco home design is its resilience. The couple collects rainwater in a 3-cubic-meter basement tank.
Wastewater flows through layered soil beds filled with biochar, worms, and plant roots. The natural system purifies the water, which is then reused for irrigation.
The greenhouse captures solar heat to maintain comfortable temperatures. Concrete floors store warmth for evenings, reducing energy needs.
Over time, the family has refined the system to efficiently recycle nutrients. Even seeds from consumed fruits, like tomatoes, sprout naturally in the beds, creating a full-cycle ecosystem.
Sylvia and Johan’s setup is unusual: they are one of only two households in Sweden not required to connect to the municipal sewer system.
The government granted special permits after verifying that their natural treatment system performs as well or better than traditional methods.
Daily life and family connection
For the family, Naturhus Torpadal is more than a house—it’s a living ecosystem.
The children grow up seeing how food is cultivated, how water circulates, and how nature and humans can coexist harmoniously.
There are minimal screens; most play happens physically inside the greenhouse or in open spaces.
Johan and Sylvia also value privacy, sight lines, and flexibility. Doors separate noisy play areas from quiet spaces.
Bedrooms are arranged to allow uninterrupted sleep, while work and training areas remain functional and accessible.
Every corner was planned to be useful, child-friendly, and sustainable.
The inner wooden home stays dry and well-preserved thanks to the greenhouse, reducing maintenance and allowing the family to focus on living fully, raising their children, and experimenting with sustainable gardening.
A sustainable greenhouse eco home design for generations
Naturhus Torpadal continues to evolve with the seasons and the family.
Each day offers lessons on temperature, light, plant growth, and self-sufficiency. Visitors often remark on how normal and comfortable the home feels despite its unconventional design.
For Sylvia and Johan, the project embodies their values: living in close harmony with nature, minimizing environmental impact, and raising children to understand and appreciate natural systems.
The greenhouse lets them experiment, adapt, and grow the home’s capabilities over time.
As Sylvia reflects on the journey, she shares a simple wish: “I hope this house will be here for generations to come.”
