Existing buildings were designed for a specific purpose, but once that purpose was no longer required and has moved to another structure or location, its former home still remains. It is with careful consideration that this sort of facility can be adapted to fit a new use, and Keystone Architecture has had the good fortune of being involved in several of these types of projects. Allowing the exterior shell to remain in tact, new contemporary uses are introduced on the interior, and in the end an interesting contrast is achieved between old and new. In fact, one project was added to the Department of the Interior’s National Register of Historic Buildings with the internal upgrades to support today’s working needs. Capitalizing on the positive physical features of the existing building creates an environment well suited to the new users of the building.
