The Raphael Guastavino Jr. House is eligible under Criterion B in the area of architecture for its association with the life of Rafael Guastavino Jr., who played a significant role in the development of architecture and building techniques of fireproofing and structural tile in America. The house at 143 Awixa Avenue was the home of Raphael Guastavino Jr. from 1914 until his death in 1950. It was here the Rafael Jr. would experiment with different glazing and firing techniques in the onsite detached garage that stands today. Guastavino, son of the developer of a renowned masonry vaulting system, developed and patented the trademark acoustic akoustolith tiles and continued to take on more prominent projects that maximized the capabilities of the system his father had brought from Spain. Engineering Historian John Ochsendorf notes, 'Although there seemed to be little difference between father and son to the outside world, Guastavino Jr.'s early projects signaled a new attention to innovation in construction.'2 It was this curiosity in improving the system that allowed the company to expand its selection of tiles and provide for a specialized market. The Mediterranean influenced house is additionally eligible under criterion C as an outstanding example of the work of Rafael Guastavino Jr. at the height of his career in partnership with prominent architect Henry Hornbostel. The Bay Shore residence is a showcase of the intricate work of the Guastavino legacy and the house retains a very high level of historic integrity.
