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.

The living room Ortal fireplace is clad in cold-rolled steel with a waxed finish. The side chairs, vintage reproductions from Room and Board, feature shapely walnut arms.

"Shane enjoys both cooking and entertaining so we maximized the counter space to make meal prep and hosting easy," Priftaj says. "It was also very important that the kitchen include a gas grill so he could quickly and conveniently grill without having to climb up five flights of stairs to use the bbq on the patio." Priftaj selected high-gloss acrylic white cabinets from bulthaup's b3 line with an aluminum backsplash and b3 prism drawer system to keep things tidy. A Wolf hood and gas cooktop with chargrill give Carslake the flexibility he desired for indoor grilling. The counters are polished white quartz.

This living/bedroom space showcases neutral tones and shades of white to contrast the continued use of natural, treated wood surfaces.

While effortlessly chic and minimalist in the final photography, Arch11 noted that much of the success of this project can be attributed to working with a construction team dedicated to craftsmanship. “Even though this modern [design] language is common, a lot of Hale Construction’s work is restoration. He [Andrew Hale] practiced his craft at the highest level,” noted Meade.

The original home’s second floor had three bedrooms with flat ceilings. Arch11 quickly realized there was a great volume in the upper floors at the gable ends of the home and chose to integrate the attic space into the second floor. This design move allowed the interior to be informed in part by the exterior while creating a bright, serene living space among the treetops.

Thanks to the extension’s vaulted ceiling, the master bedroom and minimalist staircase have views of the sky. Polly admits to having sacrificed floor area so that the full-height stairwell could achieve a stronger connection with the outdoors. Toyo Ito Mayhuma pendants hang from the ceiling, accentuating the space’s dramatic height.
