Archemancy

Ritual affects a 10 foot cube area. Any (non-magical) architecture of the affected area can be rearranged to any other form. Once completed, the caster can use an action to switch the zone between its forms if within 120 feet of the zone (line of sight not needed). Effect remains until dispelled by the caster, or is removed by another spell like dispel magic. At higher levels, increase the cube size by 10 feet or increase the number of possible forms by 1 per level above 3. The spell can not be cast as a ritual at higher levels (it uses a spell slot). Additional castings of the spell can add additional forms. 

Archemancy works by creating a magical web of force what is anchored to solid surfaces around the effected area.
