The Symphony Honolulu condominium tower recently began rising out of the ground in Kakaako, and the project developer has announced that unit sales, too, have risen.

Development firm OliverMcMillan said it has sold about 285 units in the 388-unit project, or 73 percent of the inventory.

Last July, OliverMcMillan said it had sold 200 of 288 units. Since then, the final increment of 100 units, which is reserved for buyers who meet high-moderate income limits, was released for sale through a lottery in September.

Project broker Heyer & Associates LLC said remaining units are available at prices from $390,000 for 2-bedroom units with buyer income restrictions to $3.2 million for a penthouse with 2,053 square feet of living space.

Construction on the 45-story tower at the mauka-Ewa corner of Ward Avenue and Kapiolani Boulevard began in November, and some support columns and walls have risen a couple or so stories high. Completion of Symphony Honolulu is slated for early 2016.
