XTEN Architecture is an award winning architecture firm located in Los Angeles, California, with associate offices near Basel, Switzerland. Founded in 2000 by partners Monika Häfelfinger and Austin Kelly AIA, XTEN Architecture is a full service architecture and design firm specializing in cultural buildings, office and commercial facilities, large-scale residential projects and custom single family residences. Buildings are developed using the most innovative green technologies and materials available and guided efficiently from design through construction.
XTEN has developed a distinctive method to the development of contemporary architecture, with an emphasis on open spatial configurations, material transformation and refined detailing and craftsmanship. Underlying themes in the work have focused on the conceptual use of building elements, modified with both traditional and digital techniques. In new buildings, remodels and adaptive re-use projects, the architects develop strong sculptural forms and spaces transformed by both direct and indirect connections to the building's immediate environment.
XTEN Architecture was recently awarded the International Architecture Award from the Chicago Athenaeum and European Centre for Architecture for the Openhouse, which will be on exhibit throughout Europe in 2009-2010. In 2007 XTEN won the Bienal Architecture Award at the IV Bienal Miami+Design in Miami Beach, and in that same year won architecture awards from the American Institute of Architects. In 2006 XTEN was also awarded prizes in architectural design from the American Institute of Architects, and the office's work was featured in the grand re-opening exhibit of the Architecture+Design Museum in Los Angeles. In 2004 XTEN Architecture was recognized as one of twelve Emerging Architects to watch nationally in Architectural Record magazine. The work of XTEN Architecture has been published extensively appearing on the cover of Architectural Digest, Prestige Design, Architektur and Wohnen, Interior Design Space and in Architectural Record, Interior Design, LA Architect, The Los Angeles Times, Angeleno, Elle Décor UK, Interni/ Russia, Spa De/Japan, DETAIL/ Korea, Times Space/ China, Belle/ Australia, Disenart/ Spain, AD Mexico and Deutsche Bauzeitung and others, and in numerous architectural design books.
