Inside a Modern Hamptons Home With Views in Nearly Every Direction

It's hard to pick a favorite time of year at Peninsula House. Nicknamed for its location on a point overlooking Mecox Bay in Water Mill, New York, the residence was designed by the architecture firm Leroy Street Studio to capitalize on the site's 270-degree views. An array of indoor and outdoor vantage points capture the ever-changing cinematic interplay of light and water as well as nature's shifts from season to season.
The owners, a couple with a large blended family, wanted a multigenerational gathering spot that they and their young daughter could share with the husband's adult children and their spouses as well as friends. From the outset, the clients made it clear they were looking for out-of-the-ordinary architecture that is thoughtfully, creatively integrated into its unique setting. "They really liked the idea of doing something that was countercurrent for the Hamptons," says Morgan Hare, the Leroy Street founding partner who headed the project.

Adopting a pinwheel-type plan, the striking 14,000-square-foot house features multiple wings radiating from a central core. These spaces vary in scale and height, and some feature deep overhangs, providing shade and amplifying the design's dynamic horizontality. "The oversailing roofs create a solar brim that helps keep the rooms cool in the summer," says Alex Witko, a senior associate at Leroy Street who served as the project lead. "They also amplify the views, including from the primary bedroom, where you can just sit and watch the herons on the nearby spit of land that is a protected wildlife preserve."
Softening the formal rigor, most of the house is topped with lushly planted green roofs and terraces that offer distinct vistas, while the extensively glazed exterior is clad in handmade white brick on the lower levels and dark-stained wood above. The black and white palette is one that Leroy Street, which has designed dozens of waterfront homes in the Hamptons and elsewhere, has rarely used previously. "The dark wood, somewhat counterintuitively, blends into and dematerializes against the vegetation," Hare says, noting how the house opens on all sides to tree-shaded terraces and courtyards.
Landscape architect Ed Hollander and his firm Hollander Design collaborated on the 1.7-acre property's outdoor living spaces, while outfitting the gardens with what he calls "maritime habitat" plantings, a mix of native and non-native species "that are adapted to this sunny, salty, breezy environment."

Everything in the house's design was conceived around creating a seamless flow—visual and literal—between inside and outside. The main entry consists of a two-story glass-walled gallery that connects the two largest wings, providing views from the front walkway through the house to a rear garden planted with ginkgo trees and the bay beyond. "In the morning, the sun actually comes up through that ginkgo grove and reflects off the entry hall's glass pendant lights," notes Hollander. "Then in the evening, the lights become like starlight, these magic things that dance against the trees."
Inside, the light-and-dark palette continues with the white artisanal brick, expanses of warm plaster, and pale oak and stone offset by inky-hued wood and blackened-steel accents. Throughout, the predominantly new and custom furnishings, overseen by Eleanor Donnelly of Stelle Lomont Rouhani Architects, stick to a sculptural, pared-down aesthetic, complemented by a contemporary art collection that includes works by Teresita Fernández, Sarah Morris, and Adam McEwen. Elevated details like bespoke integrated door pulls and closets with facings in faux-shagreen or mottled resin add subtle character.
The horseshoe-shaped main stairwell is one of few rounded architectural elements in the house. With floating treads and a minimalist oculus at the top, there's a play of light, shadow, and form that shifts as one moves between floors.
Reaching the home's dramatic second-story rooftop terrace requires taking a separate, private flight of stairs. A seductive spot for sunsets and stargazing, it features a seating area with a fire bowl surrounded by wispy native grasses and plants.
While a major appeal of this house is all of its intimate spaces for quiet escape, equally important was having versatile areas for gathering in larger groups. That might mean bringing two dozen guests together around the formal dining tables that can be combined and separated as needed or congregating in the various outdoor spaces around the expansive pool area.
The Living Room

The light-and-dark scheme continues in the living room, which features plaster walls, pale millwork, and cast-concrete floors contrasted by the fireplace and its surround in oiled blackened steel. The lounge chair is by Bruno Moinard Éditions, and the rug is by Liaigre.
The Kitchen

The kitchen's main cabinetry is faced in wire-brushed oak, stained to match the exterior, with partially recessed custom pulls. Storage along the far wall is clad in panels of resin-finished zinc specially crafted by the studio Wüd.
The Dining Area

Designer Eleanor Donnelly of Stelle Lomont Rouhani Architects installed a Niamh Barry light fixture over the Cassina marble tables and chairs by Inoda + Sveje for Miyazaki Chair Factory.
The Family Room

An Ochre chandelier and an Oscar Murillo painting overlook the family room, where a custom sofa is grouped with armchairs and a table by Christophe Delcourt.
The Primary Bedroom

A chaise longue and table, both by Poliform, are perched alongside the windows.
The Primary Dressing Area

Metal-framed closets clad in shagreen-textured panels line the dressing area, which is furnished with an Aqua Creations pendant light, a Gallotti & Radice pouf, and a rug by Erden.
The Primary Bath

A chandelier by Lindsey Adelman Studio hangs above a Blu Bathworks tub.
The Rear Gardens

Hollander Design created a grid of gingko trees that shades a path and terraces along the back of the house.
The Entertaining Side Elevation

Naturalistic plantings border the main entertaining spaces and multiple outdoor terraces.
The Pool Terrace

White-painted steel pergolas and a quartet of London plane trees provide shade for a variety of seating areas next to the infinity-edge pool, which is lined with Richard Schultz chaise longues designed for Knoll.
The Family Terrace

Off the family bedroom wing, a shared terrace is an inviting retreat, outfitted with Gloster furniture and an ORE fire bowl.
Hare notes that while the firm has designed plenty of residences for extended families, they have typically taken the form of compounds with separate structures. "This is the first one we've done that's multigenerational and all in one building," he says. "It was a big part of our mission—and, ultimately, the success of the house."
