Philips Arena is undergoing a major renovation two-phase project that began immediately after last season. Phase 1 is expected to be completed before the start of the NBA regular season next month. There is a scheduled concert by The Eagles on Oct. 20-21, before the Hawks open the Oct. 27.

The Smoothie King Center in New Orleans currently has the league’s smallest capacity at 16,867. The soon-to-open Little Caesars Arena is Detroit will have the largest capacity at 21,000.

The $192.5 million remaking of the 18-year-old arena will be spread over two Hawks offseasons, ultimately resulting in an array of new amenities, improved basketball sightlines, connected concourses and, perhaps most notably, removal of the wall of suites on one side of the building.

The first phase will include the renovation of about 10,000 square feet of premium club spaces and the demolition of about 100,000 square feet of interior space, according to the Hawks’ building-permit application.
