The 60s/70s era comment referred to the house being a wide but narrow rectangle. Today's houses tend to be longer than wide - Caivan's was wider than long.
There were several design elements that we did not like. IIRC, the staircase had many tight turns with narrow triangle shaped steps. I don't like those as they are a serious tripping issue. The stairs going to the finished basement felt really tight. The model home had the upgraded kitchen and we felt that the island formed a huge working barrier between the appliances. We all tend to want to work from one side of an island and we felt that we would literally be banging into the island trying to work in the kitchen.
Upstairs felt like a lot of long, narrow hallways. The master was large and seemed to have a lot of wasted space. The ensuite was nice, but the large window would require some sort of permanent privacy. We noticed that the shower doors in the washrooms all appeared to have a fixed portion at the rear end of the shower and the moveable portion at the front of the shower. This would mean you would have to enter the shower directly under the shower head and I wouldn't like that. The shower doors used were also very heavy to push and daily use could become a problem. If I had been interested in one of their homes, I would have had to get clarification on whether the shower setup could be changed.
Our interest was with their corner lot home. We liked the floor plan and the options to make some changes with the layout. Ultimately, I didn't like the lot locations and didn't like the pricing. In Orleans, it looks like they will be building towns off of Innes and this means that until the areas east of the development are built up by others, you will enter the community off of busy Innes and drive through streets built with towns to reach singles. Drive through almost any street with towns and you will encounter lots of on street parking and this can be a problem in winter trying to navigate snow filled streets.
