GlobeSt.com recently reported on the groundbreaking of 400 Sunny Isles, a 230-unit condo project in Sunny Isles. That brings the total of under-construction condo units to 565 in Sunny Isles alone, according to the Preconstruction Condo Projects Database compiled by the licensed Florida brokerage CVR Realty.
