Property size: 14,288-square-foot home has five bedrooms, six full bathrooms and one half bathroom, an attached four-car garage and a swimming pool on 4.22 acres.

Unique features: While this Ellicott City home is unique by any measure, there is no question what the main conversation piece will be — a curving, custom-built, interior slide that starts on the top floor and then winds down three levels. Riders are deposited into the open space between the foyer and living room and near one of the home’s two see-through fireplaces.

And that’s just one of three ways to access the upper, street-level and lower floors: The owners can also zip up and down in a round glass elevator or make a leisurely descent on the grand curved staircase. Another clever feature with convenience in mind — a laundry chute that dumps dirty clothes into a cabinet built above the washing machine and dryer.

The home is surrounded by mature trees and is reached by a circular driveway and a covered entranceway supported by four pillars. A long outdoor rear deck on the upper level overlooks more than four wooded acres, along with the saltwater pool with a waterfall and an in-ground jetted jacuzzi.

There are his-and-her changing rooms by the pool, an indoor sauna, and on the lower level, a billiards room and home gym.

The walk-in closet in the main bedroom is large enough to pitch a tent between the clothes racks. Other interior features include two-story windows, soaring vaulted ceilings, and heated seats on the bathroom bidets.

This house backs onto Benson Branch Park, which features quiet trails, bird song and wildlife.
