The Reflections Cleveland apartment block overlooking Raby Bay reached a major milestone last week, with the roof going on.
Developers Dario Pigozzo and Peter Endacott joined the team from builders Kyronn to celebrate the event.
"Structurally our building is now complete and the focus shifts to finishing the interior and grounds for our 59 apartments and penthouses," Mr Pigozzo said.
"By mid-September Kyronn expect to hand over the project to us in readiness for settlement."
Mr Endacott said he could not be more pleased for buyers.
"In recent weeks, we've experienced the views and aspects across each of the levels.
"We are certain our clients will be delighted when they move in during October."
Mr Pigozzo said an army of tradespeople were on site, with activity underway on every level.
"The delivery of the quality and standard of finish equal to our display suite in Bloomfield Street is our goal," he said. "This has always been our commitment to our clients.
"You will not find a better location in Cleveland. (It's) central to everything."
The developers said they were into the final stage of selling for the project, with penthouses and three-bedroom apartments in short supply.
