The Foursquare, and why it squeaks
Roncesvalles is dominated by one house type, and it happens to be the single most squeak-prone form in the city. The American Foursquare is a two and a half storey house on a square plan, which means bedrooms sit directly over living rooms with no intervening structure to break up the load path, and the stairs run straight up the middle of it. Built from 1900 through the First World War, these floors are strip hardwood over plank subfloor on sawn joists, fastened with nails that have now had well over a century of seasonal movement to work loose in. The later wave of larger homes on High Park Boulevard and High Park Gardens, built between 1910 and 1930, is the same assembly at a bigger scale. Post-2000 change here has been loft conversion of the Sorauren industrial buildings rather than new detached housing.
