At any rate. I think it would be a good idea to provide a sort of public courtyard space that would take advantage of the sun and the southern exposure. The problem is in making it the sort of place that random passersby would want to enter and enjoy. This might be solved through the programme, by assigning cafeteria space (or, rather, cafe space) to the interior spaces adjoining the courtyard. There should also be some sort of connection with the world outside -- I'm fully aware of Jane Jacobs' strictures on places that face inward too much. I doubt if there's anything attractive about facing directly out onto the gas station opposite, but the buildings on either side aren't bad-looking, and St-Laurent might be an entertaining street to watch. Pity about the distance, though.

That concave area at the top where the B arrow pierces through could be nice. I'll have to grab a few images of some similar places I've seen. As said, the gas station concerns me a little. I just hope it won't be a massive problem.
