Halletts Point, the mega development planned on a knobby peninsula in Astoria, Queens, has been years in the making, but apartments in the first building will finally be available for rent beginning this month.

In truth, this 404-unit project, known as 10 Halletts Point, has practically sailed through construction compared with the rest of the $1.5 billion mixed-use development, which eventually will have seven buildings containing 2,020 units, nearly a quarter of them affordable, according to officials with the developer, the Durst Organization.

Sure, there were minor snags with this first member of the Halletts Point family — uneven “soil conditions” from landfill that had to be dealt with and a contractor who had to be replaced.

But the larger development is stalled, once again, after hitting multiple roadblocks since the summer of 2013. That was when the seven-acre site was first presented to Durst by the Lincoln Equities Group, which had assembled the site, according to Alexander Durst, a principal and chief development officer of the company and great-grandson of its founder.
