Architect & Landscape Design

Fleetwood & McMullan has been designing houses on the east end of Long Island for over thirty years. Stylistically we are a design firm, rooted in the rich vernacular of the Shingle Style. We create livable homes, addressing the unique needs of our clients, while respecting the community and environment.

Each of our homes is unique. We only design a few houses a year. We exhaustively detail the interiors and exterior of the homes. Our designs are continually changing and evolving reflecting our clients. The interiors, for the most part, are neither totally historical nor modern. They are contextually based. Our exteriors are not only rooted in our reinterpretation of the past but on a multitude of criteria. They are unique creations. Our sequencing of spaces is modern. We think our approach to architecture is balanced. We spend time and effort in interpreting our clients’ desires in order to create individually appealing and functional homes.

Over the years our work has set a design standard that has been much emulated. We helped pioneer the reinvention of the Shingle Style in the late eighties and nineties. But more important are the rich multifaceted homes and spaces which have expanded the vocabulary on the East End.

We are located in East Hampton. The homes we design are mostly in Southampton, Bridgehampton, Sagaponack, East Hampton, Amagansett, and Montauk. The proximity is helpful to the success of our projects. We take seriously our stewardship of the environment and the satisfaction of the client.
