Castle Pines mansion tops Denver home sales in September
Former Telecom Executive Larissa Herda Sells Castle Pines Home for $8.5 Million
Former telecom executive Larissa Herda and her husband Stephen recently sold their stunning renovated home in Castle Pines for an impressive $8.5 million, making it the top local home sale in September.
The Herdas purchased the 8,240-square-foot mansion at 615 Cliffgate Lane for $2.1 million back in 2006. After listing it for $8.8 million on Aug. 22, the property went under contract just a week later on Aug. 29, ultimately closing for $8.5 million on Sept. 15.
Larissa Herda was the former leader of TW Telecom, which merged with Level 3 in 2014.
The mansion seamlessly blends contemporary architecture with Colorado’s natural beauty, sitting on 1.78 acres and featuring an infinity-edge pool, expansive patios, and a 578-square-foot pavilion.
With five bedrooms, five bathrooms, two offices, and luxurious amenities, including a resort-style primary suite with heated floors and a jetted tub, the interior is just as impressive as the exterior. The lower level offers additional living space with a second kitchen and family room.
