Designs have been approved for Carbon12, an 8 story building planned for N Williams Avenue. The designers of the project, PATH Architecture, expect that the 85′ tall structure will be the first tall building in the USA built using Cross-laminated Timber (CLT) as its structural system. The building will include 14 residential condominium units, as well as two ground floor retail units. With floorplates much skinnier than is typical in multifamily buildings Carbon12 will include only two residential units per floor. 22 parking spaces will be provided in a below grade mechanized parking system.
Carbon12 will be located at the corner of N Williams Ave and NE Fremont St, on a site that is currently vacant. In 2013 the site was rezoned at the request of the property owner from Multi-Dwelling Residential 1,000 (R1) to Central Residential (RX). The rezoning was initiated so that a project could be developed with ground floor commercial uses, which are prohibited in the R1 zone. As a condition of approval the City Council set a maximum height of 85′ for the corner of the site, stepping down to 65′ for most of the site and to 45′ adjacent to the R2 zoned properties. This is less than the 100′ height normally allowed in an RX zone, but more than the 65′ height allowed in the EX zone applied along most of N Williams Ave.
