Description

Modern Contemporary New Construction on the Hammock Course - Completion date 12 / 2020. Fantastic "Greenhaus Design - Build" home. Contemporary new construction home on the Hammock Golf Course. This fabulous home features walls of glass with 4 bedrooms and 4.5 baths, private den, family room, pool and covered patio. The tree house feel brings the outside in, incorporating lots of natural light with the beauty of the lush landscaping, golf course and lake views beyond. The open living, dining, and kitchen area feature high ceilings, with the upstairs open landing family area above. Upstairs, the sundeck overlooks the beach-entry infinity pool, covered patio, and the natural setting beyond. This new home uses strong industrial materials: solid reinforced concrete foundations and walls, structural steel for roof framing and columns, and oversized impact glass sliding doors and windows. These elements allow a freedom of unobstructed free-flowing open views and space. This home is a MUST SEE!
