This addition to the Yukon Archives facility, located at Yukon College, provides a high-performance archival environment for the storage, retrieval, administration, and consultation of records and imprint materials of permanent value. The vault addition augments the existing storage vaults and houses new paper records, photographic materials in cold storage, and digital storage vaults for electronic data.

The design is a simple one-storey storage container that provides multiple levels of protection to the archival material through functional program relationships and a high performance building envelope. The addition introduces a corridor to the existing building, which acts as an environmental buffer space. It also allows water and snow from the existing roof to be managed by new roof drains connected to the College storm water system.

The design allows for future expansion at both the north side and southwest corner of the building. It also involves significant upgrades to the existing HVAC system to allow for a stable and precise archival operating environment. A new make-up air unit in a separate addition provides filtered and humidified/dehumidified air to both the existing and new air handling units.
