Klumpen isn’t an off-grid cabin, but it does provide all the utilities needed to live away from civilization comfortably. The seven-square-meter teepee is an “off-grid utility core” that provides solar-generated electricity, satellite broadband, a shower, toilet, and small kitchen. It’s expected to cost around $35,000 plus an estimated $3,000 to ship within the EU.
The idea is to drop a factory-built Klumpen next to a small cabin and just press “on” — no need for any extra permits, plumbers, or electricians. The electrical system is built around a 7.5kWh battery with inverter to power standard 230V appliances and wall jacks. Water is recycled when possible to extend the limited supply, and an integrated heat pump provides cooling and heating when needed.
A prototype unit, developed with grant money from the EU, has already been tested. Now Himmelsfahrtskommando, an architecture firm in Stockholm, Sweden, will lead production of the first batch of ten units. A €2,000 deposit will reserve a Klumpen, estimated to ship in September 2026. If you’re planning to build on a glacier or a volcano then an “extreme-conditions” aluminum edition will be available for $198,000.
