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.

Semi retired.
I still do limited various projects for those that may need architectural work and/or designed and fabricated spatials, openings, or the restoration of any monolithic ornamentation.
Drawings and concepts submitted upon request.

From concept to finish of my design, fabrication, and installation of this interior entry to include half columns, column heads and bases, door heads, and the radiused window head. All features of the designed moldings, (Called molding segments.) column heads and bases, are prototype and matching through the repetitive reduction with the increase of the height of the assembly.
In other words, the molding parts are identical to one another but are reduced in size as the height of the assembly increases.
The material is a FGRG, gypsum, hydrocal cement with compressive strength relative to marble. Doing this type of work was a great marriage of my skills in design, art, and education in all what is here

A crown/cove molding I also designed. This is a relatively large crown molding (Business card displaying comparison.) that will look great on any ceiling that has a height of 9.5' (2.90M) plus. The projection (The distance it from the wall that is exposed on the ceiling.) Is around 6" and an exposure of roughly 6" on the wall. I personally like this molding for it's bold segmental features that are easily to impact the viewer upon entering a room. It's cove is a radical segment cut deeply into the molding's center that in appearance creates an illusion that it is recessed into the ceiling wall angle itself.
Material shown here is a standard molding plaster but, of course, it could be bench run in polymerized gypsum cement/FGRG. (Fiber glass reinforced gypsum.) Of course, I could cast it into any material. Keep in mind I can create any type of crown or molding that would successfully complement the existing moldings in a room. There's more to this practice that one would think. Molding design can require intricate shapes, styles, sizes and segments. All our purposely but strictly (Many different prominent segments that comply to the 'Orders' and of the different architectural styles.) related to the art of freedom of form and totally 'by hand' produced.

Designed Closet. Designed and fabricated this closet to include soffit for recessed lighting, elevated floor, finished mahogany wall panels, and designed compartments for shoes, clothing, etc. (I typically ever view other's work before I design anything. Would rather use my own ideas fresh without any outside influence.)

At my studios.
Restoration of a multi piece plaster crown molding to a historical property in Boston.
I sometimes design and fabricate furniture or anything related to interior design. It's not all related to the genre of architectural relief, and these things are all part of my formal education. To this day, I take courses for what's changed over the years or something that is to further my direction in some way.
The table in this series of pictures needed to be strong to hold a very heavy sculpture. Repurposed wood (Maple). Originally wanted to do a bottom section of the table the same as the top. All welds ground smooth, and I liked the natural polish of the steel that was sealed.
