Upward Architecture collaborated with the owners of Hubbard’s Corner on the adaptive reuse of a 6,400 SF unreinforced masonry building constructed in 1912, that ultimately evolved into a living laboratory for low-carbon construction materials and techniques. Envelope improvements included high performance tilt/turn window and door systems from Germany-based Schüco, hemp wool thermal batt insulation, and tuckpointing and structural connections for the unreinforced masonry shell.
The new lateral system is a 3-part arrangement of C.I.P. concrete grade beams and shear walls in the basement, a boneyard-material steel brace-frame on the first floor, and mass-timber (Vertically-Laminated Veneer panel) shear walls on the upper floor. We were also proud to be the global debut of four breakthrough low-carbon concretes engineered by C-Crete Technologies, and one engineered by Sublime Systems, both pioneers in the development of portland cement-free concretes with significantly lower CO2 emissions. The project also pilot tested Prometheus Material’s algae-grown Concrete Masonry Unit walls, another first-generation material use.
The project’s scope included elimination of natural gas to the building, a new rooftop solar array, new VRF heat-pump heating and cooling, new heat-recovery ventilation systems, cast-iron waste piping in lieu of PVC, new fire-protection sprinkles, and LED lighting. And to benefit both the ground-floor restaurant and passersby, new steel canopies were added to the south and west façades of the building to protect from the Seattle weather.
”Upward Architecture delivers adaptive re-use with a unique and value driven sensitivity to working inside of older buildings. Mark brings a maturity, expertise, and skill that typically requires going to a much larger practice. He sees around corners and can anticipate what comes next in a way few in the industry can deliver. Annalisa is creative, insightful, and with attention to detail that delivers value at every turn. Our Hubbard’s Corner project would not have been the same without their hands on and personally invested efforts.
