An insulated timber home, a greenhouse around it and planted beds that help treat the household’s wastewater: these are the main parts of Sundby Naturhus.
How the parts fit together
Glass shell
A weather-protected, seasonal space around the insulated house.
Timber home
Our heated living spaces sit inside the greenhouse in a separate, insulated timber building.
Planted cycle
Three planted beds form part of the home’s wastewater-treatment system.
Following the climate
Selected live readings give a glimpse of the greenhouse temperature and outdoor weather.
Where the nature-house idea comes from →
A protected space around the home
The greenhouse is the outer enclosure. It shelters the house from direct rain and wind and admits sunlight. Between that enclosure and the timber walls is a space for growing, moving around and spending time when conditions allow.
That extra layer changes the setting around the house, but glass alone does not make the space warm all year. Ventilation and shade matter on sunny days, while winter brings a very different greenhouse climate.
A garden that is part of the system
All domestic wastewater, including toilet wastewater, passes through three settling chambers and then three planted beds in sequence. The beds are both growing spaces and part of the treatment process. Plants and microorganisms work together in the beds.
Water, substrate, microorganisms and plants each have a role. The original construction notes document the lined beds, drainage, distribution pipes and the material used to fill them.
Looking after the house
Living here means caring for the plants as well as the building: cleaning the glass, managing ventilation and checking the technical equipment. The garden and the house are part of the same daily routine.
Experience alongside measurements
Our seasonal notes describe what living here feels like. The live readings show conditions at a particular time, while the archive records the plans, construction and measurements from earlier years.

Based on our original vision, greenhouse design and water-system documentation. The current wastewater route was confirmed by the owners in September 2026; the linked archive preserves the original design and construction record.
