I have to say though, they're great at selling product. If only their buildings were better.
Depends by what you mean by "better" - if you mean architecture (which is usually just about the only thing that most people at UT look at) - then yes maybe they could do better.
If on the otherhand you mean after-sales service - then Tridel is about the best you can do (They just won the 2007 Tarion High-Rise Builder of the Year last night at the Tarion Awards of Excellence).
Or if on the otherhand you mean environmentally friendly and energy efficient, Tridel is arguably the most advanced builder in the GTA (possibly Canada). They have a number of leading (LEED - non pun intended) programs and are also undertaking a lot on in-house research & development of implementing new green technologies in each condo. They also won the GTHBA-UDI Green Builder of the Year for 2007, which is the first year the award was given out - they've also been recognized by numerous other environmental groups and institutions for their efforts to continually push the bar forward.
Or if on the other hand you mean the quality of the units - well there aren't many other builders that people always list in MLS as a Tridel building - they've established a solid reputation among consumers who know they will be getting a quality product.
Or if you are talking about amenities, there aren't many other builders who compare - I've toured and been in quite a few new and recently built condos and Tridel is definitely the industry leader in this respect (although there are a lot of people who couldn't care less about amenities, but it is certainly a significant selling feature in large scale projects).
There are a number of reasons why Tridel continually sells more units then any other builder on a yearly basis (Concord and Monarch sometimes outsell Tridel month to month depending on project openings). They are number one in the industry and they've certainly earned it with a quality product and solid reputation.
