Building Storeys: Little House in the Valley Milne House (2008), photographed by Olena Sullivan ED: Heritage Toronto’s Gary Miedema will be making a series of posts on structures around the city included in their upcoming “Building Storeys” exhibit at the Gladstone Hotel that runs February 17-22. What do you do with an abandoned historic farmhouse that’s listed on the City’s Inventory of Heritage Properties, and now nearly strangled by bush in a Don Valley conservation area? Next time you are stuck in northbound traffic on the Don Valley Parkway between Eglinton and Lawrence, you’ll be in a great place to ponder that question. After the railway underpass just past Eglinton, you’ll descend down into the bottom of the valley, which quickly widens out. Not far away, on top of the valley wall on the left, are 1950s Don Mills homes with backyard swimming pools. Invisible on the crest of the valley to the right are the sprawling industrial buildings of Railside Road. Down in the valley, where the highway is only a few feet above and beside the river, you are cruising through the ghosts of Milneford Mills.
