The northwest section of Barrhaven is one of the oldest areas of the suburb. Within this area of Old Barrhaven are some interesting plans from the 1970s, including these designs by Holitzner. Below are the plans I have for that area along with a few comments.
The first three bungalow plans are variations on the same layout, each slightly larger.
There are two versions of the A-7 design, each with a slightly different kitchen and bathroom layout.
The plan below is quite unusual, especially the location of the basement staircase.
The family room in the plan below is extremely long!
I am not certain what the "E" series of plans are...and this is the only one I have. It looks like the same plan as the A-5...
