property. The project proposes an accessory dwelling unit sited on the east side of the property
along the alley above an approved 2-car garage.
The proposed accessory dwelling unit aims to increase the utility of the east side of the lot while

the existing dwelling and neighboring alleyway garages. The height and pitch of the garage roof
pitch are in keeping with those found on the existing dwelling. A one-bed, one bath dwelling unit
sits atop the garage. The exterior cladding is comprised of horizontal, painted wood siding that
matches the existing house and an upper portion of vertical cedar cladding that will be left to
weather naturally. Windows and doors match the scale and style of the existing dwelling.

PHYSICAL DESCRIPTION: Describe present appearance of structure/site,then contrast and compare that with it's original appearance,
noting additions,alterations,and changes in materials.Discuss significant architectural features.
This detached one-and-one-half story single-family residence with elements of the
Victorian cottage style has an L-shaped plan with a nice hipped roof porch with
elaborate turned posts and brackets and turned wood open rails. A sunroom
has been added to the south side. This a very well-maintained house. The one-
bay facade is asymmetrical and consists of an off-center glass-paned front
entrance with double-hung windows with a 1/1 sash arrangement. The upper half
of most windows is of beveled diamond-shaped leaded prisms. The fixed front
picture window is of similar design. The frame construction is finished in
clapboard with nice imbricated shingles in the gable ends. It rests on a
rubble stone foundation. The cross-gabled roof is covered with grey asbestos
shingles and features a finial pennant and verge board overhanging eaves.
There is one central brick chimney. The axis of the roof is perpendicular to
the street. Additions include a modern sunroom on the southside which is
finished in natural stained clapboard. Outbuildings include a shed of tin.
HISTORICAL SIGNIFICANCE: Justify how the persons,important events,and/or historical patterns associated with the structure/site
and surrounding area lend the property significance.
Matt Cohen 518 S. Third
Revision 1985
c
One of several very similar pattern book houses in Bozeman, this house is very
well preserved, and makes an important contribution to this block, which is
characterized by high architectural significance. The design appears to have
been closely patterned after "House Design No. 1096" in Fred T. Hodgson's turn
J of the century mail order house pattern catalog. Across the street, 513 S. Third
is nearly identical, but reversed in plan.
The house was probably built speculatively for Wilbur F. Williams, treasurer
and eventually vice-president of the Bozeman Milling Co. , which was run by Nelson
Story. Williams lived at 309 S. Third, a fine Colonial Revival style house.
The house may be individually eligible for the National Register, and therefore
of primary significance.
