Ama House by XTEN Architecture

XTEN ARCHITECTURE’S Award-Winning design for AMA House embraced the curve to yield a sublime and modern sanctuary nestled into the hillside.

A curved masonry wall, which rises nearly 30 feet along the length of the property, is one of the home’s unique architectural features. “We embraced the curve by designing a semi-circular façade that follows the form of the street,” explains XTEN President Monika Haefelfinger, “It was key in providing our clients with privacy from the elevated street which wraps around much of the property.”
More than just functional or decorative, the curving wall flirts with the orthogonal design of the two-story main house, engaging with and then pulling away. This creates pockets of exterior spaces in varying shapes and sizes. Enhanced with layered gardens, tree canopies and water features under the direction of Studio MLA, these spaces become transformative and spiritual. The act of entering the home, for example, offers a sort of ritualistic cleansing as you pass through a courtyard filled with waterfalls and lush greenery.
Just inside is the center point of the home- an expansive double-height living space with glass doors on both sides that invite illuminating natural light to flood in. The art- filled space is interrupted by bookended architectural elements: a poured-in-place concrete staircase forms a striking textural contrast opposite a tailored oak cabinetry wall. “The art and the landscape really are the central focus of this space,” observes XTEN Principal Scott Utterstrom, “With the architecture yielding to them.”

The masterfully planned site and carefully orchestrated flow follow a holistic, protean approach. "Once inside the house, sliding glass walls open in every direction creating a sense of transparency and lightness—of being one with nature," states Haefelfinger. "Woven throughout the property, there are truly special moments where the architectural and design elements just came together so organically and blend so perfectly with the landscape." Haefelfinger notes, "Like the beautifully planted hillside with a lovely staircase that leads to the guest house beneath the pool."

A SPECIAL TRIBUTE
As a meaningful and enduring memorial to the late Austin Kelly, XTEN's co-founder who passed away during the planning phases of this project, the client had a concrete caisson excavated from the previous structure permanently placed as a garden sculpture.

FOCUS ON SUSTAINABILILTY
By benching and partially embedding the structure into the hillside, XTEN Architecture minimized the foundations required into bedrock. Natural daylight and air flow freely through the house, obviating the need for air conditioning or daytime lighting. Rooftop photovoltaic panels and high efficiency systems further minimize the energy footprint of the house. Gray water systems are being utilized.
