(K. Hovnanian Homes)

The rolling hills of Loudoun County are home to plenty of classic farmhouses, but not all of them have the distinctive look of the Line K Windmill houses designed by international designer Piet Boon and Ara Hovnanian, president and chief executive of K. Hovnanian Homes.

The first Line K collection, built in the planned community of Willowsford in Ashburn, drew attention two years ago for its unusual modern style. Boon took the traditional farmhouse architectural style and reduced it with clean, simple forms on the exterior and sleek interior spaces.

The new collection of 24 houses features a similar design to the original Line K homes, but has been downsized to 3,091 to 4,029 finished square feet. Every detail from the floors to the faucets and cabinet pulls has been designed by Boon.

Each house has three or four bedrooms and four baths. The houses are priced from the low $800,000s. The De Zoeker model home, with 3,724 square feet, is priced from $879,990. This house has a traditional front foyer flanked by a formal living room and formal dining room, with an open floor plan in the back of the main level that includes a family room with a fireplace and three sets of French doors, an open kitchen and a casual dining area.

On the other side of the kitchen are a home office, a powder room, a family foyer and a walk-in storage closet.

Upstairs are four bedrooms and three bathrooms. The master bathroom includes a “wet room” with a freestanding soaking tub and a shower.
