Dallas businessman John Calvert, one of the wealthiest moguls in the U.S., is the cofounder of the Energy & Minerals Group, a specialized private equity firm focused on natural resources. According to his profile in the Dallas Culture Map, the business he established in 2006 now has approximately $13 billion in current assets under management.
Calvert currently lives in an 8,906 sq. ft., Mediterranean-style estate that was built in 1996. The home, at 9434 Alva Court, Dallas, is not currently on the market; however, real estate listing site Zillow estimates its current value at more than $8.8 million.
The home benefits from a shielded street view, thanks to its wooded, one-acre lot. Once visitors pass the gated entrance, the full impact of the home is revealed.

Inside, the architecture leans heavily into a European aesthetic, which makes the home stand out among a neighborhood of Old South tradition.

From the entry, visitors will be immediately drawn into the adjacent living room, where style and panache are evident but where the overall aesthetic is still comfortably welcoming.

The conveniently located kitchen has been designed to accommodate the distinguished chef while also being suitable for a casual meal on the go.


The dining room is unbridled upscale, the perfect setting for a five-star meal that could well conclude with Southern-style dessert, brandy and cigars.

Upstairs, the master suite is a true haven from the hustle and bustle of a busy business day. Its sheer size ensures a quiet space for shedding stress and a comforting place to drift off to sleep.

Should the homeowner wish to read for a bit before retiring, the principal bedroom has its own seating area with ample windows that enable peaceful views.

The principal bathroom is everything a mogul would expect in terms of pampering and unwinding.

A captain of industry needs a fitting place to store his or her clothing and accessories. The master suite’s closet can easily, neatly, and conveniently handle couture of all sizes.

In addition to this main bedroom, there are two others, each designed to provide luxury and restfulness to family or guests who retire to them. This one is sizeable enough to rival the expansiveness of the master.

If the upscale dining and the downtime sleeping spur the homeowners to get in some healthy cardio, the onsite gym is always open and always ready for action.

Dallas summers can be hot, making the estate’s pool a welcome amenity.

But in fall and spring, when temperatures are more comfortable, a lovely veranda is perfectly suited to al fresco dining.

Upscale horticultural designs have been liberally applied to the rest of the grounds as well.
