Three white cranes rise from the massive South Financial district (aka railway lands) excavation where the Infinity3 and ÏCE condo towers are being built.

From black asphalt to green courtyard canopy: What was once a vast asphalt-paved open-air parking area near the foot of York Street is gradually being transformed into an environmentally-conscious urban courtyard, covered by a 6,000-square-metre green canopy that will surround the base of two slender cylindrical skyscrapers — the 55- and 65-storey ÏCE Condominiums.

At the same time, what used to be a scruffy vacant lot right next door has become the building site for a new highrise condo complex, too — the 35-storey Infinity3 condos off Lower Simcoe Streets. The parking lot, which sat to the north of Lake Shore Blvd. and the Gardiner Expressway, used to be popular with people driving into the city to attend events at the nearby Air Canada Centre and Harbourfront. But it’s now one of downtown Toronto’s largest condo building excavations, where foundations for underground parking levels are in the early stages of  construction.

Three construction cranes operate high above the enormous, L-shaped pit, while the construction entrance ramps off Grand Trunk Crescent and Lower Simcoe Street handle a steady stream of cement and dump truck traffic.

Below are photos I have taken from the CN Tower of the ÏCE and Infinity3 locations both before construction started, and during the early stages of site excavation. There’s also several pics I snapped at the side-by-side condo building site on a sunny day last week, along with some artistic renderings, from the ÏCE Condos website, of the two ÏCE towers and their courtyard canopy. Above left is a website rendering of the Infinity3 building under construction; it will be a new sibling to the two Infinity condo buildings that were constructed several years ago at the corner of Bremner Blvd. and Lower Simcoe Street.

ÏCE Condos is a project by Lanterra Developments and Cadillac Fairview; the buildings were designed by Peter Clewes of Toronto’s architectsAlliance. Infinity3 is a project of The Conservatory Group. The Infinity 3 website doesn’t name the project architects; however, the E.I. Richmond Architects Ltd. website includes the Infinity towers in its portfolio. Another rendering of the Infinity3 complex can be viewed on that site.
