A cottage on a Southampton estate in New York has been reimagined to accommodate a revolving door of family and friends.
When the owners purchased their Long Island home three decades ago, they always planned to extend their cottage to host extended guests. Now, with three grown sons, they turned to their trusted designer, architect Clive Lonstein, to redesign the guest house to comfortably accommodate six bedrooms for their circle of family and friends.
Central to the new design is the harmony with its natural setting, where the guest house extension appears to have been established for quite some time. “Rather than imposing itself on the natural beauty of the environment, the home sits modestly, allowing the breathtaking greenery to be the focal point,” Lonstein says. Taking cues from the Hamptons’ architectural codes, the home sits unobtrusively on the estate with its verdant surroundings, quietly blending traditional and enduring sensibilities. “The home’s linear form maintains a classic cottage aesthetic, but with a contemporary planning style that prioritises openness and natural light,” Lonstein adds.
The living room features a custom Pierre Frey sofa, Miguel Milá TMM floor lamp, custom ottoman in Dedar fabric, Cisco Home lounge chairs, Holly Hunt bar reading lamp in gold bronze patina, Wyeth Machinist cast iron Cube side table, Reino Ruokolainen Stugo lounge chairs, Uno & Östen Kristiansson Luxus oak stool, Christopher Maschinot Apophysis lamp with hand-built stoneware, and ‘Net-Grid’ (2017) by Mandy El-Sayegh.
Featured in the main foyer is a Josef Frank no. 1020 table model in walnut and almond tree wood veneer, a custom ottoman in fabric by Claremont, paprika bowl by Freeforms, artwork by Anna-Lisa Thomson for Upsala-Ekeby sourced from Hostler Burrows, terracotta vessel by Myungjin Kim (2024), and a vintage bench.
A connection with the serene parklands is cultivated by inserting French doors into the guest house, allowing all rooms, including the bedrooms, to access the gardens without using the main entrance. An essence of openness is also achieved through the intricate interplay of ceiling heights, enabling natural light to radiate through the spaces while creating warmth and spaciousness within the various zones of the residence. “One of the key features of the design is the clever use of architectural elements, like the vaulted peaked ceilings in the bedrooms and bathrooms. This treatment elevates the sense of space, making even the most intimate rooms feel open and airy,” Lonstein explains.
Steering away from the typical coastal aesthetic, Lonstein wanted to embrace the parklands throughout the home’s interiors. “The serene colour palette all draw the eye to the views beyond, creating a space that feels at peace with nature rather than competing with it”, Lonstein says. Grounding the house further within its natural environment, oak timber floors are in dialogue with the neighbouring forest.
Warmth is embedded through layered textures and materials that furnish the home, through a gentle blend of modern and antique furnishings, lighting, VJ panelling, traditional hardware and pedestal sinks in the bathrooms, and wallpaper. An extensive collection of artworks and photographs colours the spaces, delivering a sense of a home that has been collected and lived in over time.
Through its strong connection with nature and considered material palette, Lonstein has crafted a spacious yet intimate guest house.
