Some of my long-time readers may remember that I did a series of posts on Costain a few years ago. For some reason, a few of my older posts have vanished from my blog - for reasons unknown to me. So, I have re-created this post on the builder Costain due to interest from some of my readers. On the positive side, I have been able to get my hot little paws on some new floor plans and marketing material, so there is more material in this post compared to the original (now lost) post!
In the mid-1960s the builder Costain (originally from England, but with an impressive global portfolio) came to Ottawa to develop a new hamlet in the eastern greenbelt called Blackburn Hamlet.
Today Blackburn Hamlet is very lush with mature trees and extensive parkland, surrounded by the NCC Greenbelt. The west side of Blackburn Hamlet has 3 neighbourhoods separated by parkland, Westpark, Southpark and Centrepark. The Northpark and Southpark neighbourhoods are located to the east, and I believe that this area was developed after the west side. South of Innes Road is another area that is predominantly townhouses, with detached houses on the east side.
Costain's portfolio of house designs in Blackburn Hamlet grew over the years (they built in the area well in to the 1970s), some of which were also built in their Orleans development. This post will focus on detached houses built in Blackburn Hamlet in particular, but some of the designs were built in Orleans. The older designs are presented first, with later additions below - you will notice a change in the design of the floor plan brochures. I was recently able to get a hold of some Costain plans from Erin Mills in Mississauga from the 1970s and many of the designs are similar to those built in Ottawa during the same time.
I have collected these plans over a number of years and some are of better quality than others. I may also be missing a handful of plans, so if any of my readers have copies of better quality plans or missing plans, I would love to share them - so please let me know!
In terms of house prices, Costain-built detached houses in Blackburn hamlet average around $460,000 (based on sales between April 2015-April 2016). Some smaller designs have sold in the $300,000 range and some larger and fully renovated designs selling in the high $500,000s, with premiums being paid for those backing on to the greenbelt.
Stay tuned for more posts on Costain, including their townhouse/carriage home designs and their developments in Orleans.
