Esperanza and Irwin welcome Nilay Oza and Peter Sabbeth of Oza Sabbeth Architects of Bridgehampton.   Architecture is an art form that incorporates math, science and engineering.  But it's also a business.  Nilay and Peter generously share the delicate balancing act of sensibility to the site with the needs of the client.  The familiar Our Hamptons themes of commodity vs community, and the mindset behind building (too?) big are discussed.   While it is a regional issue, Nilay and Peter illustrate the challenges of working within the very diverse and different areas of the East End, overseen by municipalities whose codes don't often align.  The role of AIA Peconic in all of this close a very spirited dialogue.
