Semerjian Builders vaulted ceiling. This spectacular groin vaulted ceiling was modeled after the nave of a 12th century Romanesque cathedral near Rouen, France. Historically these vaulted ceilings were designed in order to allow for large span widths during construction, but were perfected when church building reached its peak during the Middle Ages. Featuring massive Beaumaniere French limestone banding at the intersection of the four elliptical arches, this ceiling is situated 24 feet above the entrance Foyer of a French Norman Semerjian home. This elaborate structure was painstakingly designed and engineered to accommodate the solid limestone pieces which collectively weigh in excess of 2000 pounds. This breathtaking ceiling is a testament to one the many Old World techniques incorporated into many Semerjian Builders homes.
