Eastern Columbia Building -- Los Angeles, CA
The original building was constructed in 1929 and was part of the Art Deco era with the green terra cotta topped off by the Clock Tower at the roof. The KOR Company turned the building into high rise lofts in 2007. Charles Pankow Builders was in charge of tearing it apart and rebuilding from the inside out.
D 7’s initial work included testing the existing windows for leaks and designing the new waterproofing and roofing systems. Due to the nature of the design, it took several types of waterproofing to create the protection required for this type of building. A hot rubberized asphalt membrane was installed over the original roof deck prior to construction of the pool deck. Once the remaining structure was finished, the PVC roofing, acrylic waterproofing and elastomeric coating provided additional protection.
D 7 provided Design services for KOR in association with Killefer Flammang Architects. D 7 also provided Quality Assurance Observation during the difficult application of the many systems. Creating a new building out of an existing 78 year old high rise proved quite challenging. This building stands out on the corner of 9th and Broadway right in the heart of the Fashion District of Los Angeles.
