It was no surprise when the most expensive home sale in the Denver metro area in June was in rural Boulder County. The area is home to plenty of serene acreages with impressive homes.

It should also come as no surprise that all signs point to the couple who bought the $4.25 million home and 40 acres along St. Vrain Road near Hygiene as being one of Boulder’s most well-known, Brad Feld and Amy Batchelor.

Feld, of course, is a managing director of the venture capital firm Foundry Group and a co-founder of startup accelerator TechStars. Batchelor is a philanthropist and co-authored with Feld the book “Startup Life: Surviving and Thriving in a Relationship with an Entrepreneur.”

Boulder County property records show Denali Property Holdings LLC, an entity registered to Feld, as the purchaser of the home, which had been bank-owned. Batchelor announced on her blog last month that the couple was placing their Eldorado Canyon home for sale and moving north of Boulder near Longmont as they looked for a “rest-of-the-life house where we could live well into ripe old age.”

A Realtor.com listing for the seven-year-old home on St. Vrain Road shows it as a six-bedroom, four-bathroom, 10,821-square-foot luxury retreat with views of the Flatirons and a large shop and barn.

The couple’s home at 450 Kneale Rd. in Eldorado Canyon, located on 33 acres, is for sale for $2.5 million, with an option to purchase two adjacent parcels for a total of 114 acres. It is listed at www.goodacreproperties.com.
