The smallest scale in electric powered Model Railroading thus far (sort of*) is Z-Scale (1:220).
It was introduced by the Märklin company in 1972.*There is a smaller model run by a puff of air if you want to count that.
These Mobile Homes can provide residences for your Z-Scale model layout or they are just fun to look at on their own.
Built with details we offer the finer lifestyle in mobile home living... from a Weber Grill or Wishing Well to a Dog House.
They sit on a 3" x 3" base and housed in a plastic display cube. Trees are approx 2" tall.
Tbase can be removed from the cube and mounted directly onto your layout. Place in the background of a larger scale to give your layout depth.
