We’ve all seen houses with sunrooms on the market, but an estate with a custom curved-glass solarium? Now that only happens once in a blue moon.

Also referred to as a conservatory, a solarium is a room designed with glass for the purpose of providing immersive views of its surroundings — and in the case of the recently listed Cold Spring estate, the immediate views are the wooded acres across from Cherokee Park.

The historic property, built by members of the prominent Speed family in 1867, has hit the market for $4.995 million. While the main house has undergone an extensive renovation to bring it into modern times, including all-new electrical and plumbing systems, the rest is still unwritten — just like that one Natasha Bedingfield song.

The 6.71 acres of the Highlands estate include the main, unfinished four-bedroom house, a renovated carriage house, and mature parterre gardens. Here’s a closer at each house.

The estate was originally listed in April at $5.25 million. | Photo by Kentucky Select Properties
