The Lofts at Brownwood
Below is a rendering of The Lofts from the Daily Sun. I noticed this week the construction zone has been fenced in and there is now earth moving equipment on site.
As far as Brownwood Blvd, I've used that road to go to the square ever since that square opened. It's convenient, it's an easy access rather than driving down through all the shops, and I usually found a parking space behind the sales office which was close. Entering the square now from the north, I'll probably use Powell Rd instead of Buena Vista, and use the traffic circle just before Traverse Shopping Center and park behind Toojays or in that vicinity.
