Built for Tech Execs: This $4.7M Midcentury Estate Near D.C. Features Radiant-Cooled Floors and a Secret Bar

An energy-efficient estate with integrated smart home technology in a gated enclave in Clifton, VA, is being built for a buyer who wants a new home focused on wellness, privacy, and recreation.

Located about 25 miles outside Washington, DC, on 5.03 acres in Clifton Reserve, a private collection of just three bespoke new construction homes, the 10,154-square-foot midcentury modern home is being built with wellness designed into it.

Listed for $4.7 million, the six-bedroom home will have natural stone, wood details, high ceilings, and expansive windows that let in abundant natural light.

“The cool thing is it features hydronic water, which is a technology that was brought over from Europe to warm the floors during the winter and cool them during the summer,” said listing agent Katherine Massetti of Serhant. “It was also designed to reduce allergen risks with less airborne dust (than forced air).”

The homes in the gated enclave, built by ACG Custom Homes, will have clean angles, low-slope roofs, and cantilevered overhangs.

“This is true midcentury modern new construction,” Massetti said. “It’s a two-level home that is focused on entertainment and living space. It’s a one-of-a-kind masterpiece that will be completed in Q1 2027.”

Designed to flow with the outdoor space, the open floor plan will have retractable glass walls that open to a heated saltwater in-ground pool with waterfall features, a spa, a sun deck, and a covered pavilion with an outdoor kitchen and private shower.

The main-floor primary suite will be silently cooled through its floors and ceilings, which helps keep humidity steady. The suite will have a stone fireplace, plaster walls, custom wood paneling, dual dressing rooms with revolving shoe towers, and a spa-inspired bath with full-height Viola marble shower walls and marble flooring.

The home will also have a secluded en-suite bedroom that could be used for multigenerational living.

“The target audience is someone in the tech business world,” Massetti said. “It’s about 15 minutes from the Tech Corridor. I think the next buyer will be someone who is wellness focused and wants to entertain with retreat style living.”

The gourmet chef’s kitchen will have a 10-foot ribbed Pietra Grigio marble hood, full-height stone backsplash and counters, contrasting Statuary marble double-waterfall islands, integrated LED lighting, custom European white oak cabinetry, and high-end appliances. A separate catering kitchen will be designed for hosting larger gatherings.

Other amenities will include a full spa on the nearly 5,000-square-foot walkout lower level, which will also have a sauna, a fitness center, a hidden speakeasy with a full bar, a wine wall, and a 12-foot LED screen.

The private lot will also have EV infrastructure, solar power with battery backup, and a climate-controlled three-car garage.

“Clifton offers a lot of acreage with a small-town feel,” she noted. “It has lots of Victorian homes dating back to the 1800s, so it has this old vibe, but it also has highly rated restaurants. It also has a community vibe with local ice cream and coffee shops as well. It’s super cute and has a getaway feel to it tucked away from northern Virginia and DC life.”
