Contractor AMT Enterprises, Rocky Hill, Conn., wanted this 6000-square-foot model home in Middletown, Conn., to be special. With energy-efficient features, energy-star rated appliances, and luxury home amenities, such as a home fitness center, home theater, and sauna, this home would showcase the versatility of concrete. The natural benefits of concrete, as well as its decorative intricacies, lent itself well to this open-air designed home.

The small squares on the kitchen floor were hand-brushed with multiple layers of onyx-colored stain to reach a deep color. Black grout creates the tile look and coats of urethane create a shiny, glossy sheen.

Winters in Connecticut can be harsh, so it was important for the Country Club Road Residence to be as solid and airtight as possible. All of the solid exterior walls are made of insulating concrete forms (ICFs) creating a seismic-, hurricane-, sound-, fire-, mold-, and insect-resistant home. Where needed, a open-cell urethane spray foam was used for insulation. The basement and garage floors are lined with a 2-inch-thick rigid foam board insulation, and sand and 10-mil poly vapor barrier underneath the concrete to provide further insulation and waterproofing protection. The remaining floors used fire-resistant steel joists and steel decking, complete with a layer of open-cell urethane spray foam. Radiant heating is carried throughout the home andgarage to maintain a comfortable living environment.

Floors throughout the house were acid stained and featured custom designs.
Michael Osgood/AMT Enterprises LLC Floors throughout the house were acid stained and featured custom designs.

A key feature of the floors is a unique acid-stained design. The floors were diamond ground to a smooth finish and applied with a white polymer cement overlay. The patterns used were created by making cuts with a worm drive saw and vacuum attachments. The floors also received two coats of 100%-solids high-build ultra-clear epoxy and two coats of high-solids urethane. Floors throughout the home used a number of colors, from marigold, mahogany, powder blue, and green. Sawcuts separated the colors to add emphasis. In the kitchen, amber-colored acid stain was applied over the floor. Onyx was hand-brushed in many layers to create small squares, and black grout was layered between urethane coats.

The master bath featured a glass mosaic design set into a thin layer of seamless texture overlay. After lightly diamond grinding the surface, the green and amber broken glass was set off by an earth tone stone color.

The 5x5-foot shower stall was handtroweled with integrally colored polymer cement and sealed with applications of epoxy and urethane. Artwork of ivy was hand-painted on top of the surface.

An airtight structure was an important aspect of this New England home. Doors, windows, and other penetrations were sealed with expandable foam. In addition, the attic rafters and roof sheathing also are insulated. The use of concrete is carried outside with stamped concrete patios and walkways, and a stone and stucco veneer on the front of the house.

Further plans for the home include a 50-yard concrete driveway, a built-in grilling area, a rock-landscaped waterfall, fire pit, and hot tub spa.

The entire project used 214 1/2 yards of conventional and decorative concrete.
