Services
We want to renovate and add to the house we already love. Also, we really need to update the 'house by the pool' because we love to entertain there. We have major wetlands constraints and will need to abandon our existing house. The new house needs to be modern and we have to capitalize on the amazing views of the water.
We believe that architecture centered around your needs will result in a home that you will love. We are focused on looking for opportunities to make your ideas shine and creating a home that is centered around you and your family.

Over the past twenty years we have developed partnerships with civil & structural engineers, surveyors, interior designers, local builders and developers, energy consultants, and environmental specialists with a focus on wetlands needs all over the Hamptons area.We have worked on projects of all scales from new construction, total renovations, focused renovations, additions, decks, pool-houses, sheds, and planning studies.
A family approached our office to design a contemporary Cape Cod style house. We worked closely with the owners who were committed to detail and well versed in traditional American architecture. Due to the nature of the property, we performed acoustic and view studies to develop the layout of the house.
This is one of our earliest projects. As a freshly licensed architect, Zac was eager to work closely with the homeowners to develop their dream shingle style home. Early on, the family told Zac they wanted a roof deck but wanted to be certain that the views would be worth it.

Since they were working with an empty lot, Zac took the initiative and climbed a tree in the approximate location of the proposed roof deck to capture photographs of the bays and harbor beyond.This was critical to the client decision on the roof deck location and orientation. Zac's approach to making a personal investment in client needs set the precedent for our design team.

I highly recommend Zach Clanahan. We needed an architect to reinvent our backyard to make the space enjoyable for our family. Our contractor recommended Zach and we were impressed with his other projects in the neighborhood. We are glad we chose Zach! He thoughtfully listened to our objectives -- a pool house to host guests, patio space, pergola, etc. He also was very knowledgeable of the Southampton Village building codes, which facilitated approvals. We are very happy with the result and look forward to enjoying the space for years to come.

Working with architect Zachary Clanahan exceeded my expectations not only in professionalism, accessibility and competitive pricing, but also in creating an outstanding design beyond my dreams. If you want to work with an architect with exceptional skill, who listens to your needs, who makes recommendations when you may not know exactly what you want, who is honest and responsible, and who takes great pride in his work, hire architect Zachary Clanahan!
