L-Tower penthouse suite at Yonge and Front lets you look out and up out of the same  big window

By Stephen Weir

There are now eight luxurious penthouse units for sale at the L-Tower project in downtown Toronto.  When built, these two-level skyboxes will be at the top of a 58-storey all-window condo building, where their mass is all glass!
“ The problem with all-glass buildings is that they all begin to look the same, unless you are willing to make a bold move,” said Sam Crignano, partner in Cityzen Development.  “Architect Daniel Libeskin has done just that  … no more so than with the 57/58 floor penthouse suites!”

The penthouse suites will have 2-storey tall, all-glass windows.  For the units facing north up Yonge Street, the glass actually angles in a curve over the two floors giving residents not only vertical views outward, but also upwards to the sky!
Famed US architect Daniel Libeskind designed the modernized Royal Ontario Museum, the new World Trade Centre at Ground Zero in New York, and the Crystals at CityCentre in Las Vegas Nevada.  Now he has designed the L Tower, a 58-storey 600-unit condo tower that is being built onto the side of the 50-year old Sony Centre at the southeast corner of Yonge and Front Streets.
North facing penthouse condos can see up and out!
Libeskind’s L Tower is shaped like a glass canoe that has been stood upon its stern.  The north side -- facing up Yonge Street -- will have a noticeable hull-like bulge near the bow of the building.  There is a huge wow in the front of the building -- the glass slopes out and then back in  towards the top of the building -- it is here that the windows become, for a few metres, both the wall and the ceiling of these top drawer suites.
The building is reportedly 88% sold. As of the new year, all of the $1.6 million to $3.2 million penthouses are still available.  The suites range in size from 1,068 to 2,400 square feet. These are two-storey living spaces with high ceilings up to 14 ft tall.
“ These are being built loft style, with all the amenities (top-of-the-line Miele appliances, a wine cellar, super-sized closets, steam shower, heated marble floor) including an elevator in each unit!” explained Crignano.  “You can actually put a glass elevator in the suite near the outside window. Not totally sure of the design of each penthouse because some people might want to buy two units, put them together and get both a North and South view.”
A building where penthouse dwellers can see up Yonge, and up at the North Star out of the same window hasn’t been done before in Canada.  By placing a large multi-floor bulge in the north wall of L Tower, Cityzen and its partners Fernbrook Homes and Dominus Construction Group have literally been forced to think outside of the glass box.
Take the curved curtain-wall windows.  The 10 ft tall slabs of glass are heavier and more durable than standard condo windows, and are currently being custom made in northeastern China.   They will soon be transported by ship to BC and trucked to Toronto to meet the completion date of Fall 2012.
All of the windows, be they straight or curved, will be self -supporting and attached directly to the structure of the building.  Even though some of the windows will curve, owners will still be able to have blinds installed to keep out the prying eyes of those low flying Porter planes.
Clean windows are essential for an all glass penthouse, but how do you clean a wall of glass that has a multi-floor undulation?
The L-Tower’s big bulge creates a challenge for window washing.
At the L-Tower you won’t be able to just give a worker a bucket and a squeegee and lower him down from the roof, the way traditional box towers do.   On the North wall a wash platform would bang into the bulge.
Anchor Engineering System, a Toronto firm, is designing a telescoping platform that will be able to push itself away from the building to clear the multi-floor bulge.
“ There will be a large slot in the mechanics area above the penthouses, some 630 feet above street level (63rd floor)” explained Anthony Pignetti, the director of high-rise construction with the Dominus Construction Group. “ Inside will be a troll3y crane that will run up and down the sides of the building with a boom, and telescope-like arms.”  It can also be used to effect repairs if windows need to repaired or replaced.
So unique will this cleaning system be that owners of the new penthouse should consider holding washing parties as the Canada-Arm-like device cleans their up and out windows!

Tower – Artist’s take on the new L-Tower.  The penthouse suites n the 57 & 58th floors are not actually at the very top of the all-glass structure.  There will be several mechanical related floors above the penthouses.

Libeskind ruined Bloor Street with his hideous Crystal. How did we let him disfigure our skyline as well. Shame on Toronto for letting this self-promoting and horrible person back into our city.
