“When the cost of land can be shared, it brings the cost of living down,” says Union Studio architect Christina Carlson. “It’s a very adaptable way of developing, and it’s also solving some of the affordability issues.”

Separate but Together

An arresting blue paint turns a wall in the ADU’s living area into a focal point that livens up the whole space. The furniture was chosen for its practical and compact design. “It’s usable and comfortable, but minimal in scale,” says Enright. “There are no big, oversize arms, and pieces are up on legs so it feels airier and more open.” Paint: Harwood Putty (walls, vaulted ceiling), Prussian Blue (nickel gap wall), by Benjamin Moore; Skylights: VELUX; Light Fixture: Progress Lighting; Rug, pillows, throw: Annie Selke; A sleeping nook, rather than a full bedroom, saves a few feet; the triple-pane casement windows are installed high enough to allow for multiple furniture arrangements.

Black & White Bathroom

The matte black fixtures in the ADU bathroom echo the aesthetic in the main house and coordinate with the black and white porcelain tile on the walls and floor.

A Functional & Stylish Kitchen

A countertop between the ADU’s galley kitchen and its living area can serve as a dining counter for a meal-on-the-go. The apartment floor is character-grade white oak, with a darker finish than the select oak in the main house. Paint: Bruton White (kitchen walls); Harwood Putty (living area walls), Prussian Blue (nickel gap wall) by Benjamin Moore; Cabinetry: Woodharbor Custom Cabinetry; Floors: Baird Brothers Fine Hardwoods The kitchen’s galley layout creates an effective workspace that doubles as a passageway to the main house. Beyond the kitchen, a sliding barn door conceals a coat closet, and is set off from the wall far enough to hang art behind it but close enough to slip between the wall and a high-top table that provides dining space for two. The apartment can be entered through a front door beyond the refrigerator, through a slider off of the living area, or from the main house through the kitchen.
