A 55-and-older residential community is being built on a golf course west of Delray Beach as developers build on financially strained greens in South Florida's land-scarce market.

Avalon Trails will have 217 villa-style townhouses and 304 single-family homes at the Marina Lakes Golf Course northwest of Atlantic Avenue and Jog Road.

13th Floor Homes LLC, the homebuilding arm of Miami-based 13th Floor Investments LLC, began construction of the townhouses this week. The one-story townhouses will have two and three bedrooms.

Big-name Miami-based homebuilder Lennar Corp. will develop the single-family homes at Avalon Trails.

13th Floor Homes' townhouse portion is branded as active adult based on its amenities: a clubhouse, full-time lifestyle coordinator, resort-style pool, lap pool, card rooms, gym, cafe, courts for tennis and pickleball, and a 2.5-mile trail.

13th Floor Homes bought the 110-acre Marina Lakes Golf Course at 14800 Cumberland Dr. for $5.4 million in June 2018. The course closed in 2014.

Avalon Trails is one of many residential projects in South Florida rising on golf courses after heavy development during the game's heyday from 1986 to 2005. Florida still is in the lead with 986 courses in 2018 despite all the course closures in recent years.

Pulte Group Inc., a residential developer based in Atlanta, is developing four courses. On tap are a 405 single-family home and townhouse complex on Oakland Park's long-closed Oak Tree Golf Course and a 645-home community on Hollywood's Hillcrest Golf Course, with half of the homes completed.

It also is developing a 130-home adult community on one course at Boca Lago Country Club, which kept its second course, and a 152-home complex on part of Woodmont Country Club in Tamarac.
