An oak ceiling adds coziness to the sunroom of a family retreat on Martha’s Vineyard, Massachusetts, devised by architect John B. Murray. Designer Mark Cunningham, who oversaw the interiors, installed Ralph Lauren lanterns above a custom Fern table from Fair with Stahl + Band chairs. In a seating area, gray upholstered vintage chairs and pine stools by Fair join tufted Dune lounge chairs around an Adam Court coffee table from Studio Twenty Seven.

At the center of the large family room, a Charles Paris pendant is suspended over a pedestal table by Cunningham and chairs from his furniture collection, Marked, while a Richard Misrach photograph and a Brent Wadden textile work frame the doorway to the stair hall.

A Maren Kloppmann ceramic wall sculpture overlooks the sunroom’s Cunningham-designed sofa, and a Sam Moyer artwork hangs above a custom demilune console by Walter P. Sauer.

In the living room, an artwork by Rebecca Ward is installed above built-in shelves by Murray and a table and chairs by Marked. Next to the velvet-upholstered armchairs by Cunningham, a Peter Speliopoulos lamp for Marked rests atop a Demiurge side table.

The kitchen is outfitted with custom oak cabinetry by Murray, Caesarstone countertops, oak flooring, and a Pelle pendant that hangs above the island lined with counter stools from Design Within Reach.

A vintage Guillerme et Chambron armchair and an Azadeh Shladovsky side table stand beneath a Harold Ancart painting in the living room.

A Francesco Balzano bench from the Invisible Collection stands at the foot of the primary suite’s Marked bed, which is dressed with E. Braun linens, a Frette coverlet, and pillows in a Schumacher fabric; Mark Albrecht Studio sconces complement the Holly Hunt nightstands. 

Cunningham designed the TV room’s built-in sofa with a window nook where he hung a Hiroshi Sugimoto seascape photograph.

In the primary bath, which is lined with Taj Mahal quartzite from BAS Stone, a painting by Michele Fletcher is mounted above an MTI Baths tub.
