In the dining room, the design team updated the fireplace with green tiles from local manufacturer Bantam Tileworks that add texture to the original ornate mantle. The custom banquette (featuring Dedar pillow and banquette fabric with Samuel & Sons accent piping) frames the perimeter and “captures this idea of the window bench from the living room and replicates it here where there’s great natural light,” Brannan says. In addition to roman shades from Holland & Sherry (fabricated by Lakeville Interiors), chandeliers from Champalimaud’s collection with Visual Comfort, In Common With sconces, and Zafferano tabletop rechargeables imbue the interiors with a soft glow, while tables made by local maker Ian Ingersoll and Ton chairs fill the space.

The midcentury-inspired Mews building—home to 20 guestrooms—backs the pool, which is framed by umbrellas and loungers from Teak Warehouse. Built for the property, the completely new area is a “gamechanger in the region,” says Brannan, where there’s an absence of similar outdoor amenities.

Formerly a sunroom, the green-hued jewel box of a bar commands attention in the dining room. Ceiling paneling existed before, and the team carried it through to the newly built bar done by White Dog Woodworking. The pop of color is courtesy of Benjamin Moore and evokes a “swanky London vibe,” Brannan says, which comes alive thanks to fringed pendants from Honoré, whimsical table lamps from House of Hackney, and accent lights from Visual Comfort.

The pool is adjacent to a subterranean spa. Upon arrival, guests are led from an ethereal reception to a dramatic steam room. Here, white floor tiles from Nemo Tile + Stone and walls wrapped in blue tiles from Daltile make the spa feel “authentic to the property,” Brannan notes.

When guests enter the hotel, they’re greeted by a reception desk from White Dog Woodworking tucked under the staircase with its original spindles and featuring plaid carpeting from CM Hospitality that carries through to the corridors. “We wanted to create these warmer layers,” Brannan explains. This is highlighted by the grasscloth wallcoverng by twenty2, a table lamp by local manufacturer Dumais Made, and a picture light by Mullan Lighting that gives the space a residential feel.

In the Library, another original fireplace adds a layer of history to the custom table by Dumais Made, the Fortuny ceiling light, wall-to-wall-carpet from Kasthall, and Ton chairs upholstered in Pierre Frey fabric that “kind of looks like Missoni,” says Brannan. Dumais also made custom lamps that sit in the built-in shelves, which are filled with books, artwork, and sculptures that are either family-owned or sourced locally.

Because every layout was different, the team had to get creative when it came to the guestrooms in the main house. Take that attic, which has been transformed into a three-bedroom suite. The twenty2 provided custom striped wallcovering that complements sofas from Sixpenny and Anthropologie as well as a custom window bench from Carlos Custom Furnishings that is topped in Dedar fabric. A coffee table from owner Anthony Champalimaud’s personal collection completes the look.

During the renovation, Brannan and the team uncovered many interesting details. Among them is the pre-existing window bench (now covered in Casamance fabric and flanked by wicker lamps from Soho Home) in the living room. When the team opened it up, they found an old wallcovering in a wisteria pattern, which they incorporated into some of the guestrooms. The centerpiece fireplace complements an original chandelier that Champalimaud updated with new shades from Shandells. A cozy couch by B&B Italia in Kravet fabric sits on a rug from the Rug Company, while the corner banquette from Carlitos Custom Furnishings creates an intimate nook. “We made this room feel like a lounge space that could also be used as a coworking space,” Brannan says.
