Originally constructed as a single family residence, its most recent occupancy was as faculty offices in Use Group B. The proposed continuation in Use Group B will remove occupancy of the finished attic space on the third floor as part of the proposed energy improvements. Public access is limited to the first floor. Three staff offices proposed for the second floor. The existing configuration of space remains largely unchanged with areas of alteration consisting of less than 50 percent of the aggregate work are and is classified as a Level 2 Alteration. The applicable provision of Chapters 6 and7 apply to this work.
