The EB1 Residence by Replinger Hossner Architects is located just Southwest of Seattle, in a simple neighborhood. The steep sloped lot, not uncommon in this area, presented a challenge to the architects who responded with a modern, cantilevered design. Offered at $895,000 in 2008, the 2,600 square foot property was sold in May 2009 for $780,000. Steeply sloped lots are among the most common remaining undeveloped single family building sites available. While often alluring with potential drama and views, steep sloped environments are often geologically unstable and contain fragile eco-systems. They are generally difficult to access and their development is highly regulated.
Eb1 is designed as a specific response to this environment. The striking cantilevered design allows the entirety of its 2,000 square feet of living space to rest on two 16 foot long concrete piers set 16 feet apart and braced together with steel. The pier footings step with the grades and are in turn supported by three-inch diameter, pneumatically driven, steel pin pilings. This foundation system allows for development to occur with an absolute minimum ground disturbance and environmental footprint. Site impact was further mitigated by obtaining an access easement from above the site, avoiding grading through the steep slopes from the adjacent street below. And if you’re planning to have your own house, remember: temperature is very important in making a comfortable place to live so search for a Seattle heating and ac service and put it to good use !
