structure 3ds

The Massage trusses are higher in a series to give a vaulted ceiling.  Trusses are the most efficient way of using timber as they are braced triangles the members can be quite small using less wood.  The massage is more like gothic cathedral space so it might be the "cathedral of massage"?  There is a loose mushroom like shape with the sloped roof and small base with diagonal bracing under.

Here are 3 d renders of structure for the shower which is a series of trusses radiating around a connection to the rock.
