  2. 2. Plan Genesis Why did we choose a curve? • Extending the unit-related geometry into an addition that doubles the size of the building called much attention to itself and started to present a clear challenge to the historic building fabric. We found ourselves trying to bury or lower the addition at every turn to minimize its impact and the loudness of the geometry. • When continuing the unit-related geometry, we fell into many of the similar geometrical complications created by this A geometry. Triangular rooms and 60-degree corners present particularly difficult challenges in the realms of furnishings and flexibility. • When our peers (architectural historians and critics) reviewed 60 o the previous unit-related designs, a consistent concern was raised: Why are you following the same geometry? Doesn’t B this mimic too closely work of Frank Lloyd Wright? These peers have seen many additions done to historic buildings and the most successful response across the planet is to make a clear R C O departure from the original architecturally and geometrically. S • The curve was the simplest and the quietest gesture we could S I N G make in response to the intense geometry already present on the site. The curve is largely read from the sky. It is almost unperceivable when you first enter the site. On the ground it is D a soft and subdued form that lightly touches the upper B-wing. atrium • A curve always refers itself back to its origin. Here, the curve auditorium is generated from center points within the Meeting House and C therefore, is always tied back to it. At just about every point in the Crossing, a line of structure or architectural feature leads your eye back to the Meeting House. In this way the curve is self-denying. We felt that this was an appropriate N poetic gesture for an addition on this site to make. The curve reinforces the iconic power of Wright’s landmark.

Option 2: Air Quality Testing was selected. Conduct baseline IAQ testing, after construction ends and prior to occupancy, using testing protocols consistent with the United States Environmental Protection Agency Compendium of Methods for the determination of Air Pollutants in Indoor Air. strategy: EPA conducted air quality tests prior to occupancy.

Reduce the quantity of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants. requirement: All adhesives and sealants used on the interior of the building (defined as inside the weatherproofing system and applied on-site) shall comply with the requirements of the South Coast Air Quality Management District Rule #1168. strategy: The design team specified low- VOC (Volatile Organic Compond) materials in the construction documents. Each adhesive and sealant used on the project met LEED standards for VOC levels. For example, the allowable VOC limit for cove base adhesive is 50 g/L, and the cove base adhesive used had a VOC content of 1g/L. T h e k u b a l a wa s h aT ko a r c h i T e c T s , i n c .
