In the guest bathroom, Givone installed a hand-chiseled sink made of 17th-century marble quarried from the hills outside of Rome.

A couple enlist Butler Armsden Architects and Leverone Design to reimagine their home as a multigenerational meeting point. In 1963, landscape designer Lawrence Halprin devised a master plan for a community that would live in harmony with the natural environment. The resulting Sea Ranch, which stretches 10 miles along the Pacific coastline in Sonoma County, California, is characterized by timber-frame, wood-clad structures that are in dialogue with the local climate and terrain. Sited on a bluff within this pioneering community is the vacation home of a lawyer couple. After purchasing the residence in 2007, they lived in the home as it was for four years, even keeping the previous owners’ furniture. Envisioning a retreat that would accommodate their extended family and guests, they then recruited Butler Armsden Architects and Leverone Design to help guide the project.

Just beyond the open-plan kitchen and dining room is the living room with a Gelderland sofa and JOV rug.

The addition’s two stories of cedar-framed sliding doors and window provide generous views of the house’s prized jacaranda tree. The addition’s polished concrete floor and white cladding extend into the garden, drawing occupants to the serene rear porch. There, they can relax on stools designed by Alvar Aalto and Charles Wilson while admiring the luscious greenery.

Black accent pieces create the illusion of a black and white kitchen in the home of San Francisco architect Cass Calder Smith. A black reading nook coordinates perfectly with the stainless steel countertops and white cabinetry.

Foyer

Concentré de Vie Two upholstered seats and two pouffes fit into a shell to make a traditional sofa; when removed, the flexible seating arrangement could furnish a small room.

The bar showcases many green products. The bar top, made at the 19 greek street gallery, is fashioned from recycled glass, and the chairs, from both Out of the Dark and Studio deForm, are fashioned from upcycled material.

According to Ndoro, LIBRARY will “provide a much-needed space for the pioneering design community of the capital and beyond.” This room features a collection of eclectic Middle Eastern and African pieces, according to 19 greek street founder and creative director Marc Peridis. The curvaceous M'Afrique Shadowy Chair by Moroso is made by Senegalese craftsman, the rug and vases are fashioned from recycled African fabric. The two Papillon chairs near the window are by Karen Chekerdjian, a designer based in Lebanon.
