The existing site contains a two-story single family residence built in 1910 and a one-car garage with driveway parking, both facing the Tracy street front, with the garage set a little further back than the house; and behind the residence in the back of the lot exists a 528 sf greenhouse with a roofed walkway connecting the residence and greenhouse. The greenhouse is half-sunk in the grade, roughly about 4’-6” from ﬁnish ﬂoor elevation up to existing grade. We are proposing to remove the upper portion of the greenhouse, leaving the existing concrete basement half-walls, and building a new 600 sf ADU above the lower portion of the greenhouse, utilizing the existing foundation. The existing greenhouse half-basement to remain would become storage and mechanical space. The ADU’s entry will face the alleyway and provide an ADU-dedicated parking space off the alley. The ADU is an A-frame shape with white siding and black-framed doors/windows, consistent with existing form, scale, and materials of the main residence, as well as the surrounding neighborhood. 423 North Tracy (Project Site) Photos Image 1: frontside of existing single family residence on Tracy Street front Image 2: back of site from the alleyway showing in the foreground a skate ramp (to be removed), the existing Greenhouse (ADU proposed location), a storage shed just to the left (to be removed), and beyond that is the backside of the residence and garage STEWART STUDIOS Architecture & Design PH: 406-581-5212 StewartArchitectureStudios@gmail.com SSSStewart tudios There are several examples of ADUs in the surrounding neighborhood, many of them as a second ﬂoor located above a garage.

Montana MODIFICATION 20-370 August 24, 2021 The ADU has been slightly modiﬁed from its original NCOA (20-370 Tracy ADU NCOA) approval. The building location on site, footprint, square footage, and proposed parking spot remains the same. The overall aesthetic remains largely the same, including the building form, materials and lighting; but for budgetary reasons the Loft north & south dormers have been eliminated, some windows in the south and east elevations have been eliminated (see proceeding pages), and north windows have been simpliﬁed to be the same size/operability. The western facade window/door conﬁguration shifted slightly north to accommodate a structural beam and post. A Garden Water Closet and Mechanical Room have been added to the basement ﬂoor for functional purposes. The roof pitch has also changed from a 12:12 to a 10:12 pitch to better accommodate the functionality of the kitchen (increasing the plate height and allowing the north window head heights to push up). These changes are pointed out on the proceeding pages, showing the original NCOA 20-370 approved plans on the left, and the proposed Modiﬁcations on the right. W.C. and Mech.
