606 O'Connor Street, the Glebe, Ottawa

This post-war rental walkup is very much of the style one sees dotted here and there throughout the city, wherever developers were able to find property parcels. Six units are arranged bilaterally around a front-facing, windowed stairwell. This example, finished in sand-coloured brick, sits at the SW corner of 4th Avenue and O'Connor. Ads first appeared in the summer of 1958 — the block replaced a 1½-storey wooden house facing onto 4th Avenue, built in the latter 1890s.

While this configuration was (as best I can tell) originally meant to face the street (as we see above) ideally overlooking at least a token spread of lawn-space, builders often found themselves forced to make the best of long, narrow domestic lots as they became available. Thus we find buildings arranged like this —

— the plan has been rotated by 90° and the building wedged in sideways. aesthetics be damned. This block at 185 Frank was completed in the summer of 1951. If it looks cramped, that's because it was built on what had been a service lane / parking area behind the Kenniston Apartments (on Elgin.)

#185's twin, 200 Waverley (per the ad above, now numbered 196) was built the previous year, at the north end of the same laneway.
