About Phase 2 Architecture & Interiors

Phase 2 Architecture & Interiors was established 25 years ago by current owner and architect Jay M. Leistner, AIA. The Phase 2 team of five has a combined 79 years of experience in the field. During these years we have worked with clients along the East coast from Florida to New York.

Our mission is to provide excellent, innovative & personalized architectural and interior design services to our clients. By being active listeners and responsive in our process, we strive to work with each individual client in a team approach toward an end result that addresses not only the client's needs and budget, but also enhances their use of the space.

Dear Friends at Phase 2,


How can Jim and I even start to thank you for the Cape May project’s outcome? Our house is beautiful and functional beyond our hopes and expectations. We can’t stay away - even in the dead of winter!

I am considering becoming a docent. A dozen strangers have walked by, and so obviously want a tour, that I am happy to welcome them in. Their jaws just drop when they walk in the front door. The house still looks like it fits right into the neighborhood, albeit bigger, but when people walk in and see that soaring ceiling, the porches and decks, the soaring ceiling in (my) master bedroom reading nook, they are blown away. And the way you reused/repurposed so much of our existing furniture, it makes it all seem familiar and brand new at the same time.


Every project we’ve worked on with Phase II (is this the third?) has been seamless and a delight. You are some of the most talented people I know. Jim and I, and our entire family, have a real Shore House now.


Thank you! All our best, Nancy and Jim Marshall
