Jackson Park Town Site Addition Brick Row is a group of three historic houses and two frame garages located on the west side of the 300 block of South Third Street in Lander, Wyoming.

The 1+1⁄2-story brick house at 615 South Third Street was built for Alexander (Scotty) Johnston, a successful sheep rancher, in 1917.

A full-length porch built on the front of the building features a hipped roof supported by boxed columns.

A similar bay window with a hipped roof is located on the right (north) side of the home, next to a tall brick chimney.

The second floor, accessed by a bracketed oak staircase at the front entry, contains four bedrooms and another bathroom, this one sporting the original cast-iron bathtub and pedestal sink.

The 1+1⁄2-story Arts and Crafts bungalow at 635 South Third Street, sandwiched between the other two houses of the Jackson Park Town Site Addition Brick Row, was constructed in 1919 for Leslie Read (grandson of pioneer Lander businessman Major Noyes Baldwin) by carpenter Dan Packard.

The house shares three tree-lined lots with a detached two-car garage accessible from the alley running along the property's south (left) border.

Also on the rear of the house is a 1989 addition on a concrete block foundation, with exterior walls finished in wood shingles, a picture window and a gable roof.

The gabled second-floor ends of the building are covered in wood shingles and feature triple-ganged double-hung windows.

The home's roof is covered in asphalt shingles, and features the exposed rafter tails and knee braces.

The inside of the house echoes the Arts and Crafts styling of the exterior, with oak flooring and pine woodwork.

The house's exterior is covered in brown brick, with the concrete foundation visible for approximately one foot above grade.

Sharing the back of the structure with the attached garage, a large enclosed porch sports six double-hung windows and a hipped roof.
