Allen graduated from the London School of Economics in 1974 and had careers in Management Consulting, Software, Restaurants and Internet startups prior to founding One Sky Homes in 2002. For the past twelve years One Sky Homes has developed extensive experience in high-performance residential design and construction.
Allen hails from a long line of Silicon Valley entrepreneurs. His grandfather founded the first broadcast television station, KNTV channel 11, in 1953. His father built the local cable TV system Gill Cable now owned and operated by Comcast. Allen grew up in Willow Glen living next to Willow Park and is currently a Willow Glen resident.
Allen is a licensed California contractor, a Certified Green Building Professional, a Certified Passive House Designer and US Dept of Energy “Building America” Partner. He regularly participates in regional, national and international Passive House conferences and speaks to local building professional and student groups about high-performance building. He leads One Sky Homes' Design|Build team, which focuses exclusively on Net Zero Energy and Passive House projects in Silicon Valley.
Bronwyn has worked in the green building industry for over 20 years. After earning her bachelors degree in South Africa, she moved to the US where she apprenticed at various architecture firms. She founded her own residential design practice in 2000 which she ran for 8 years. Her projects were selected for early Built It Green Home Tours and won multiple awards. During this time, she helped found the Green Remodeler’s Guild, now called the Green Building Professionals Guild, run by Build It Green. Prior to this, she trained and led California’s first All-Women Construction Crew at Mt Diablo Habitat for Humanity, where she integrated green building concepts into all chapter projects.
In early 2008 a trip to Germany convinced her of the elegant simplicity of the Passive House Standard, which she has been promoting ever since. Her presentations on high performance windows, specifically for Passive House, have become ‘go to’ reference documents for those working in this field. Bronwyn has presented on Passive House at regional, national and international conferences and was most recently invited to present at the 16th International Passive House Conference in Germany, 2012.
Bronwyn joined One Sky Homes in 2011 as Director of Design and Sales. She collaborates with Allen as the lead designer on new projects and oversees Sales and Marketing. She is an internationally Certified Passive House Designer, an Associate AIA member and serves as a current and founding Board member of Passive House California.
