Tomorrow, Tuesday 23 February 2010, the City of Ottawa's Planning & Environment Committee (agenda) will be considering an application to alter the zoning at Laurier, Bank and Slater, to accommodate the third phase of the Standard-Life buildings in addition to the ones at 280 Slater Street and 333 Laurier.
Here's an overhead shot from Bing Live Maps. The tall red-ish building at the top is 333 Laurier, and its fraternal twin to the North (below it in the photo) is 280 Slater.
The parking lot between it and the buildings along Bank are to be part of the proposed new 18-storey building, and the facades of the heritage buildings are to be incorporated into the new development. More on that later. The block at the corner of Bank and Laurier, once a furniture store and now owned (or at least occupied) by a forestry workers union, is not part of the development.
Here's an aerial shot from 1926 that includes the site. At the centre of the shot is the Jackson building, and the block south of it (to the lower-right) is the subject block. It's certainly changed a lot since 1926.
