The Related Group plans to build a three-tower mixed-use project at the waterfront Brickell site it is about to acquire. Related is scheduled to close on the purchase of 444 Brickell Avenue next Monday for an undisclosed price, the company announced. Previous reports indicated the company had a contract to buy the four-acre site for about $100 million.

It intends to develop One Brickell on the two properties. Plans for One Brickell include 1,200 residential units, a five-star hotel with about 200 rooms and convention space and at least 200,000 square feet of office and retail space. Two prominent architectural firms, Miami-based Arquitectonica and Pelli Clarke Pelli of Connecticut, have been hired to design the towers and commons areas. The 80, 70 and 55-story buildings would total more than four million square feet.
