Farm parking for motorhomes: between demand and bureaucracy

Switzerland saw 110,000 registered motorhomes in 2023, a 50% increase since 2020, but only 104 official farm parking spots exist due to strict zoning laws. The Huber family in Birrhard (Aargau) has offered motorhome parking for nearly 20 years, recently obtaining permits for four spots after lengthy procedures. The spot costs 18 francs per night including electricity, contributing 5,000–7,000 francs annually to the farm through shop sales.

The total cost of the project is estimated at 5.7 million francs. The campsite will include 46 equipped pitches for motorhomes and 13 pod/bungalow units, as well as common areas.
