Who are Masada Custom Builders?

Masada Custom Builders was created in 1987, by Isaac Ohayon and Naomi Alter-Ohayon. A pedigree of first-class carpentry and design is behind Isaac, who first learned the trade from his father, a master carpenter to the King of Morocco. The guiding principles of Masada are superior craftsmanship, cost effective production, unparalleled reliability and outstanding client satisfaction. Over the years, we’ve worked closely with architects and buyers in developing homes with uncompromising quality.

As a firm focused on custom-designed luxury residences and spaces, our experienced team of professionals provides a comprehensive range of services meant to surpass every client’s need. We recognize the importance of cultivating a strong relationship with our clients to be able to interpret their dream home and create an exceptional product.

We work closely with neighborhood associations, as well as many prestigious architectural firms. Our custom homes can be found throughout Center City Philadelphia, the surrounding Philadelphia Main Line suburbs, New Jersey and Delaware. Taking into consideration the regional ambience of each location, our homes are a marriage of function and design.
