Location: La Quinta, California, United States
Architects: XTEN Architecture
Architect in Charge: Austin Kelly AIA, Monika Haefelfinger SIA, Scott Utterstrom, Tina Rothermund, Jae Rodriguez, Qichen Cao, Christina Kaneva, Dana Nishimura Bryan, Stephanie Sent
Landscape: Pamela Burton & Company
The Madisonhouse is perched on a knoll in La Quinta, California, near Palm Springs. In order to shelter the house from extreme desert conditions, the massing and materiality are configured to protect against the sun and strong Northerly winds. Concurrently the house opens completely along an East-West axis culminating in a spectacular indoor-outdoor living space with full height glass walls that slide away to embrace the desert landscape, light and mountain views.
To the South a large volume containing service spaces buffers the house against the solar gain, and opens to the courtyard, the kitchen area and at both ends. To the North a volume containing bedrooms creates a windbreak to severe winds that can reach 100mph. These volumes frame a courtyard, the main entry gates and a series of glass pivot doors, the main entry to the house.
An East-West shift in these volumes creates the space for an open kitchen/ dining/ living area that expands laterally across the entire West elevation. This is the main space of the house and it opens completely to the landscape. Glass doors on three sides pivot and slide away and disappear into hidden wall slots. The terrazzo floors and white plaster ceiling extend the space horizontally out the landscape. Separate secondary volumes – a stone fireplace, a dark oak kitchen, a 30-foot long wood and marble island, an oak cabinet and floating cast terrazzo stairs — anchor the space and conceal all the structure and systems required for the large spans and cantilevers.
A partial second story bridges the lower volumes and contains the master bedroom suite and an outdoor terrace/ fireplace area. The spaces on this floor are also configured with strong volumetric, solid/void relationships to create a free flowing indoor-outdoor series of spaces opening to the landscape.
Building components, assemblies and fixtures were selected to achieve environmental goals. Insulated Concrete Formwork (ICF) walls were used throughout the project, creating super-insulated R60 assemblies. Four-foot thick stone and concrete walls, deep glazing recesses and large cantilevered overhangs were calculated to shield the house from massive desert solar gain. The house opens in every direction to draw air through a second story thermal chimney. The courtyard reflecting pool and main pool provide evaporative cooling for the ground floor areas. High performance glass, high efficiency mechanical systems, fixtures and photovoltaic panels further reduce the energy profile of the house.
The project was conceived as a series of freestanding volumes set beneath and between projecting horizontal slabs. These freestanding volumes in stone, concrete and oak are spaced and configured to create the different scales of indoor-outdoor space that flow between them. Large open and fluid spaces are framed by massive solid and fixed elements. Light white terrazzo floors and countertops are bounded by dark rift oak wood cabinetry. Rough stone walls frame openings of precise metal and glass doors. There are eighty sliding glass walls in the house, all configured to slide away and disappear completely into hidden wall pockets. There are few materials used throughout the house but they are used in a multiplicity of ways indoors and outdoors throughout the house.

XTEN Architecture is an award-winning architecture firm based in Los Angeles, California and Sissach, Switzerland. Founded in 2000 by partners Monika Häfelfinger SIA and Austin Kelly AIA, XTEN Architecture is a full service architecture and design firm specializing in custom residential, cultural, institutional and commercial buildings. Architectural designs are developed using innovative materials, advanced structural strategies, sustainable technologies, and guided from schematic design through the successful completion of construction.
XTEN approaches architecture with an emphasis on strategic planning, open spatial configurations, refined material detailing and the highest level of craftsmanship. Through research and analysis, the architects distill the parameters of site, structure, project brief and resources into strong sculptural forms at the scale of the landscape. The interior-exterior spaces created open to and are completely transformed by direct connections to nature and the buildings’ immediate environment.
XTEN Architecture has received numerous architectural awards, including several International Architecture Awards from the Chicago Athenaeum/ European Centre for Architecture, the National AIA Housing Award, several American Architecture Awards, AIA California Council Architecture Awards, the IV Miami+Design Bienal Architecture Award, the Los Angeles Architecture Award, the Bloomberg Luxury Property Award, Custom Home of the Year Award and a number of awards from the Los Angeles American Institute of Architects. The work of XTEN Architecture has been has been exhibited in the US and Europe and published extensively, appearing on the covers of Architectural Record, Architectural Digest, Elle Décor, Architectur und Wohnen and in the New York Times, The Los Angeles Times, Wallpaper, MARK, Architectural Record, Interior Design, Angeleno, LA Architect, FORM, Interni/ Russia, Times Space/ China, IW/ China, DETAIL/ Korea, IDS/ Korea, Spa De/Japan, Belle/ Australia, Disenart/ Spain, REM/ Portugal, AD Mexico, Deutsche Bauzeitung amongst others, and in numerous international architecture and design books.
Current work in development and construction include residential, hotel, apartment, retail and cultural projects in the US, Europe and Asia. In June 2013 recent projects by XTEN Architecture were exhibited in “A New Sculpturalism: Contemporary Architecture from Southern California” at the Museum of Contemporary Art (MOCA) Los Angeles.
