1) Typical outbuildings in Old North Knox would have included carriage houses, barns, outhouses or servants'quarters, often more than one-story tall and built with steeply pitched gable roofs or combined gable and shed roofs, with weatherboard or board-and-batten wall covering.
2) The proposed garage acknowledges and suggests the function of original carriage houses that would have been located in the neighborhood.
3)The proposed size is compatible with that of early carriage houses and does not overwhelm the house. (New info added as of 3/17/2016) The proposed garage footprint is 40% of the house footprint. The garages in ONK and Fourth and Gill are generally between 25% and 35% of the house footprint.
4) The design of the proposed garage doors that face the street are proposed to mimic carriage house doors.
5) The materials proposed in constructing the garage buildings, with the exception of the metal windows and doors (Revised 3/17/2016), are those listed in the guidelines: wood siding with a four-inch lap, overhanging eaves, masonry foundation, and garage doors appearing to be carriage doors.
6) The proposed main roof pitch at at 8/12 is the same or steeper (which is appropriate) than that for other approved garages in the district . The 5-V-groove metal sheathing is appropriate for outbuildings.
7) There are proposed to be four skylights in the roof that will not be visible from the right-of-way.
8) The proposed fiber cement board will be a very minimal part of the sheathing, on the dormers only, which is an area prone to moisture damage and rot.
9) The proposed site for the garage, in the location of the former garage at the head of the driveway and to the rear of the house, is an appropriate site for the garage. (Added 3/17/2016)
