shed, country house, countryside
墅 centers on a rural dwelling: a simple shed or a country house set in the countryside.
墅 combines 野 (field, countryside) with 土 (earth, ground), suggesting a building on rural land. The exact historical development is uncertain, but the component combination fits the meaning of a countryside dwelling.
The top 野 means fields or countryside, and the bottom 土 is earth. Picture a simple shed built on the earth out in the countryside.
For ショ, imagine a show being put on in a countryside shed: show -> ショ, and the shed becomes a little stage.
