The clapboard sheathing has been covered with aluminum siding. The lot, in keeping with the walking scale neighborhood in which the Lyles-Sims house is located, is long and narrow but is otherwise devoid of historical features. The interior of the house also exhibits the asymmetrical complexity associated with Queen Anne style architecture. The most impressive space is the front parlor. One enters directly from the outside into the room itself, which is dominated by a stairway on the right with two quarter landings, turned pickets, heavy newels with bulbous finials, and a pendant.
Wainscoting extends up the stairway and along the walls of a portion of the front parlor.
The front parlor also contains an original single-shelf mantelpiece. The crown moldings and the base moldings are quite simple, again throughout the house. Immediately behind the front parlor is the dining room, entered on the right by a new hallway and on the left by an enlarged hallway. Behind the dining room is the original pantry. Substantial changes have been made in this portion of the Lyles-Sims House, which is probably part of the original dwelling.
