An 18-wheel tractor trailer with a fire-engine red cabin was stacked high with lumber as it rolled slowly through the streets of Moorefield Green, a new development in Ashburn, Va., midway between Leesburg and Reston.

Single-family houses and townhouses are sprouting on about 90 acres that luxury homebuilder Toll Brothers bought from the Claude Moore Charitable Foundation. “We’re creating an urban scene with houses close together, common open space and a diverse group of residents,” said Scott Canan, senior project manager.

Many streets and sidewalks are finished, houses with brick facades are up and pocket parks are dressed with young leafy trees and blooming flowers. There are also construction crews in Day-Glo vests and hard hats working on empty lots, driving bulldozers and paving driveways.

There will be 528 homes making up five collections each with several floor plans. Four collections — Amberlea, Fremont, Manors, Oxford — offer 473 townhouses. One collection — Huntington — offers 55 single-family houses.

Since sales opened in March, more than 100 contracts have been signed. The first settlement will be mid-May.

George Shi, his wife, Helen Ren, and their 5-year-old son plan to move into a single- family Huntington model this month. A 19-year-old daughter is away at college.

“From the sales contract to now has been a very smooth process,” Shi said. “I feel this is the right place to buy and this is a good community.”

He liked the house design, materials and construction. “When I look at the doors, windows, all the details inside, I see they aren’t cheap,” he said.

Flexible floor plan: “This is definitely a high-end community, one level up in poshness,” said sales manager Andrew Cope. The molding package is upscale. So is the railing going up the interior stairs — dark brown banister and white spindles. The 1,000-square-foot basement comes finished and includes a full bath. The large open kitchen is convenient “because you can have all your friends over for a giant party. It’s a great entertaining home.”

The hallway on the second floor attracted Shi’s attention because it’s spacious and looks good. “You’re definitely not getting the feeling of being in a tight corridor,” Canan said. “We created a usable open hall design outside the bedrooms.”

The linen closet door is glass-paned, which adds depth to a small space. The laundry room is stocked with a large heavy-duty washer and dryer.

Two of the smaller bedrooms are connected by a buddy-bath or Jack-and-Jill bathroom. “Seventy-five percent of our buyers are looking for this option” usually for their children, Canan said. The fourth bedroom contains an en-suite bathroom, as does the master bedroom, with a corner soaking tub, double shower, double sinks and vanities, and toilet in a separate room with a window.

The large windows throw natural light into all the rooms in both the single-family houses and townhouses. Off the kitchen on the main level of the townhouse model is a spacious deck, which makes it easy to set the table and carry the food outside for an open-air meal.

The lower levels of the townhouses are above ground and include a garage, bedroom, full bath and walk-in closet. The standard option on the upper level or fourth floor is a loft that can be reconfigured as office space, play area, bedroom or lounge.

What’s nearby: You can walk to Harris Teeter Food Market & Pharmacy adjacent to the property or pedal your bike. In downtown Ashburn, there are restaurants and bars, take-outs, coffee shops, movie theaters and nightclubs.

Construction of the 4,500-square-foot clubhouse, to be outfitted with a meeting room, pool table and fitness center, will be underway soon. “We just got the permits to start building and plan to open Memorial Day Weekend 2016,” Canan said.

Shi said he will be happy not to pay for the gym. “In Fairfax,” where he lives now, “I have to pay a monthly fee,” he said.

There will be adult and tot pools, an amphitheater, outdoor grills and open, grassy areas ideal for picnicking. Trails and parks are plentiful. As the community develops, “there’ll be twists and turns on our sidewalks. Hardscapes and softscapes,” Canan said.

Schools: Moorefield Station Elementary, Stone Hill Middle, Rock Ridge High.

Transit: The best transportation option is yet to come — the last Metro stop on the Silver line, which will be in walking distance — but it’s the primary attraction now.

“That’s what’s creating urgency. People are coming to look,” said Canan. Shi said the Metro will make the location very convenient, and even now it’s good for him because he works in Reston, and “it’s just a drive of one mile to the [Dulles] Greenway.”

Wiehle-Reston East Metro station on the same Silver line is the closest stop now and is 15 miles away.

Moorefield Green is reached by car via Interstate 66 to Exit 7 followed by a short drive on Loudoun County Parkway. It’s 11 miles to Dulles International Airport and 30 to 35 miles to Reagan National Airport, the U.S. Capitol and the Smithsonian Air and Space Museum on Independence Avenue NW.
