Known as the Thomas Smith and Arthur Coleman Houses, the semi-detached homes were originally built by Toronto contractor Arthur Coleman in partnership with painter Thomas Smith. Each semi has a lower two-storey suite (main and lower levels) and an upper suite (second and third floors). On the other side, you're flanked by towering high-rises, which can make living in a two-storey heritage home feel a little less charming. The other downside for us regular folks is that all that history and luxury come with a hefty price tag. The upper unit is listed at $4,295,000, the lower at $4,795,000, and if you want the whole thing?
