Brigitte Shim (of Shim-Sutcliffe Architects) invited Gabriel Fain and I to the Daniels Faculty this morning (at the University of Toronto) to talk about Mackay Laneway House.

It was for a class on laneway housing and, as it turns out, some of the students had been using MLH as a case study. That's pretty cool, although the primary lesson is probably "don't build next to large trees."

Following the presentation, we had a good discussion about laneways, and it reminded me of some of the things that I believe to be true. More specifically, it reminded me of what I think will happen in the future:

• Bona Fide Streets: Laneways will become bona fide streets. Meaning, they'll get real names (most don't have one today) and they'll get serviced. Today, laneway suites are typically serviced via the main/existing house.

• Severable Lots: Laneway lots will become severable. Right now this is strongly discouraged, because the intent is to create new rental housing and not new for-sale housing.

• Market Inversion: Once these lots become severable, the market will then be able to decide which frontage is most valuable -- the current street side or the laneway side. Maybe some get split right down the middle (50/50) or maybe some get biased toward one frontage. Either way, I think it will become common for the laneway frontage to be more desirable given its intimate scale and pedestrian orientation.

• Mixed-Use: Non-residential uses will become allowed.

I have no idea when all of this might happen, but I believe it will happen. So I wanted to write it down publicly.

One of the most famous and important houses in Toronto, and in North America, just sold. It was reported last week in the Globe and Mail in an article called, "Integral House finds buyer amid wave of high-end Toronto deals."

Designed by Shim-Sutcliffe Architects, the 18,000 square foot Integral House was commissioned by mathematician and musician James Stewart. It was completed in 2009 at a cost that seems to vary widely depending on where I look online. But it did just sell for $18 million.
