» Lagom House

Lagom House

Lagom is a Swedish word meaning ‘not too little, not too much, just right’. This is the philosophy we designed and live in our little home. By building small we could minimise not only our physical footprint in regards to raw materials and waste in construction, but also in the ongoing maintenance, heating, cooling and cleaning. It’s size also aids in preventing the accumulation of “stuff”. Lagom has a passive solar design, and produces more power than it uses.
