Here are the photos that Dawn Arnold posted:
Looks like nine storeys equivalent.
The T&T article states the design was submitted based on an RFP issued by the city.
The building would include some ground floor commercial, with the remainder being residential, except for the top floor which would be "common space." The building would include some affordable housing units beginning at $1142.00 per month.
Note the extension of Atlantic Avenue through to Main Street, although access to Atlantic would be westbound only, and egress would also be westbound only.
I personally consider this design to be preliminary only, and that it could change. There has been no information released as to whom the potential developer is. This is all very preliminary, but this will be a substantial and welcome addition to the downtown west end.
