Insulated friggebod 15 sqm – the 18 m² alternative

For a long time the insulated 15 sqm friggebod was the largest you could build as a friggebod without a building permit. That limit no longer applies as a separate rule. Our alternative is an insulated 18 m² house with kitchen and toilet, delivered in one piece.

Three questions to ask yourself

Will someone sleep there in winter? Then you need heating and ventilation, not just insulated walls.
Is a toilet needed? Otherwise it means walks to the main house in the dark and cold.
How much allowance does the plot have left? Add up sheds, garages and carports built without a permit.

Insulation in practice

An insulated shed without installed heating and ventilation easily becomes damp. In a house meant for staying in, we plan ventilation, heat source and windows together, so the house works even when it stands empty for a week.

If you really need 15 m²

Say so in your request. We explain what a smaller size would mean for the layout and whether it can be offered.
