My design of a barrel vault with ribs and castings in a wet bar area of a new home. (This was a prototype of design by me of no other influence, and before barrel vaults achieved their recent popularity in the last decade.) All within this photo I designed, fabricated, and installed including the molding's, bed molding, roping, and vault ribs, as well as the molding's segmental properties.
Material is of a FGRG, hydrocal formulation of gypsum cement. Exceeds the compressive strength of most marble. (I did not do the sculpture of the corbel [Ancon], but they are interchangeable if one may prefer something else.)
All barrel vault ribs (Moldings on the radius of the vault ceiling) we're done insitu as the radius was imperfect. (It eliminates the spaces between the rib and the ceiling done on a bench.)
The molding at the openings of the vault are an enlarged version of the ribs inside the vault ceiling to create depth.
This pattern of the molding features (segment members) were of my conception to hand drafted templates and they weren't copied from other's work. All my conceptual moldings in all applications are always original.
The roping in the bed molding was a cast feature that returned into the corbel head on the face side of the wall and also serving as a corbel head in itself.
I also do fireplace surrounds, door/window heads, exterior/interior entryways, stone archways etc. Anything, essentially to do with form.
