To answer some of these questions:
Pricing starts at $1,500/sq.ft. (for the courtyard facing units) and goes up to around $2,100/sq.ft. depending on layout, orientation, outdoor space, floor level. 70% of the units have unique floor plans and they vary greatly so pricing will be reflective of that. When it was first launched a little over a year ago, the pricing was eye-popping, but considering the high level of design, detail and quality of this development it's actually reasonable considering what you are getting and you won't see such features and design in other condos. 123 Portland (Minto) launched about a month ago and it has been selling briskly (now almost 70% sold) and the prices were $1,350 to $1,900/sq.ft. and their finishes seem pretty average (the renderings show interiors with lots of extra-cost upgrades). The Well (Tridel) just south of KING Toronto has been selling quickly and last time I looked pricing was $1,500 to $1,900/sq.ft.
Everything at KING Toronto has been thought out and well designed down to the littlest detail, so you do get what you paid for. That being said, KING Toronto is almost sold out with over 80% sold (East and North Mountains completely sold out with some units remaining in the South and West mountains), and the sales centre will close after this week (to be relocated in the Shangri-La) to make way for demolition and construction.
Landscaping including the planters in all of the residence's terraces and balconies has been thoroughly studied and worked out. The microclimate of each terrace has been analyzed to determine the best plant species to thrive and require less maintenance. They are all irrigated and have a deep enough planting bed to allow it to stand up to our 4-season climate.
There is no hotel component here, so there are no special considerations when it comes to financing/mortgages. There will be ground-floor retail/commercial along with 5-story office spaces along King Street, but those spaces are not part of the condo corp and have their own addresses, so again there will be no financing concerns.
Vancouver House has been selling well and is out-performing other condos in their market. The chart below shows the comparison of Westbank projects compared to their closest competing buildings (courtesy of Westbank). I'm hoping Westbank will set a precedent and trend of high design and quality in condo design over our sea of cookie-cutter towers across the city.
