Well trapezoid was how it was described to me, but I really didn't ever think it would be verticle, it makes little sense as the psf increases with each floor - one reason why Ritz did the inverse to increase square footage on the top floors.
Overall it appears to be a very interesting plan and preserves some view corridors from the first two phase which is good news for purchasers.
This comes in at 489 feet, perhaps with mechanical it may be over 500 feet. It does appear somewhat wide in the east/west elevation, but I'm fairly confident that Lanterra will produce an attractive tower and the shape will present some interesting angles and opportunities for interior layouts. The atrium could be very attractive at street level.
