On 3½ acres along Pickett Road in the city of Fairfax, two four-story condominium buildings over two concrete garages are filling up.

A mix of 80 one- to three-bedroom units — some with dens — and nearly a dozen floor plans is attractive to move-up or first-time buyers, which comprise about a third of the sales, and to the “move-down,” or downsizing, market, which is strong, said Patrick J. Rhodes Jr., vice president and senior project manager at the IDI Group Cos., the builder. McWilliams Ballard is handling sales.

IDI, owned by the Cecchi family, has been in business 42 years and is renowned for development of Leisure World. “We know what the active-adult community likes and offer a lifestyle change that’s comfortable and affordable,” Rhodes said.

“We’ve taken the suggestions purchasers have given us over the years to make a home work for them and incorporated them into our designs and floor plans,” he said.

The Enclave embodies those structural and design elements. For example, features include an open floor plan with kitchen, living and dining rooms forming the core living area; large windows; a master bedroom situated apart from the other rooms for maximum privacy; and abundant storage space inside and outside the unit.

Right-sizing: Anne Hall downsized into a three-bedroom-plus den on the top floor in January. “I had definite ideas about what I wanted, and southern exposure was a must,” she said. She actually got both southern and eastern exposures because her unit is a corner.

“I wake up every day and am happy I’m here,” Hall said.

Bruce and Connie Lauther also moved in January from a house they’d lived in for 34 years. “We noticed a sign for condos going up in mid-2016 and zipped right in,” Connie Lauther said.

“We’re ‘right-sizers,’ ” she said. “We came from a three-level house and had to get rid of a lot of stuff, but didn’t mind because the rooms here are spacious and we’re very comfortable.”

Walking through the glass entry door into the lobby is pleasant because it’s as though you’ve entered someone’s living room. There’s a couch, side chair, coffee table and glossy, dark-blue wall bookcases.

Straight ahead, through glass doors, is the Club Room, with seating areas for small groups around square game tables, on high stools along a bar top and on side chairs. Residents can rent the room for private parties. The Lauthers play bridge and look forward to inviting their club members. A fitness room is inside.

A fire pit and barbecue patio will be built. “We’ve created an outside environment because we know our residents like to be active,” Rhodes said.

Nearby: “The location is a wow for every need and age,” Bruce Lauther said. He said he’s happy that George Mason University, the Annandale campus of Northern Virginia Community College and the county recreation facilities at Oak Marr RECenter are close, and the greenery of the Army-Navy Club is within a mile. He applauds the Fairfax Regional Library and historic downtown Fairfax, with its restaurants, visitors center and museum.

Shopping: Fair City Mall has 40 stores, dining establishments and commercial venues, including Shoppers Food & Pharmacy, Best Buy, a cinema, beauty salons, a tailor, a dental office and clothing shops. Trader Joe’s and Wegmans are in Fairfax. The Mosaic District is less than two miles away and is a shopping and entertainment destination for locals and visitors — especially with the Angelika Film Center, which offers indie movies.

Schools: Daniels Run Elementary, Lanier Middle, Fairfax High.

Transit: The community is about 20 miles from the District and minutes from downtown Fairfax. It’s south of Interstate 66 at Exit 64 and south of Virginia Routes 50 and 29/Lee Highway. The closest Metro station, Vienna/Fairfax-GMU on the Orange Line, is about a mile away on the CUE bus route, which “takes you within four-to-five easy walking blocks of anywhere you might wish to go within the city of Fairfax,” Bruce Lauther said. A bus stop is steps from the Enclave buildings. The MetroBus 29N route connects with the King Street-Old Town Metro station on the Blue and Yellow lines in Alexandria and with Alexandria Union Station on Amtrak.
