One or more photo(s) has been virtually staged. Pre-Construction. To be built. PRE-CONSTRUCTION / TO-BE-BUILT - CONSTRUCTION HAS NOT STARTED. This listing represents a proposed home design only and offers two purchase options on a private 5-ACRE homesite in Oviedo: buyers may purchase the LAND ONLY for $619K and build with their own builder, OR work with the CURRENT BUILDER to construct the proposed custom modern estate with the ability to PERSONALIZE layout, finishes, and features prior to construction. The proposed residence is designed as a fortress-style, energy-efficient estate featuring Insulated Concrete Form (ICF) walls and a standing-seam metal roof for exceptional durability, storm resistance, and long-term efficiency, with a planned 6-bedroom, 5-full-bath, 1-half-bath layout that includes a fully self-contained “Grandma's Suite” cottage with its own kitchen, living area, and dedicated carport-ideal for multi-generational living, guests, or a private office retreat. The conceptual open-floor plan showcases vaulted ceilings and a dramatic great room anchored by an EPA-certified Madison wood-burning stove, along with a planned 1,400-square-foot unfinished bonus room upstairs, pre-designed to be pre-plumbed for a future bathroom and kitchenette, offering flexibility for a theater, wellness studio, game room, or additional guest space. Additional proposed features include an oversized 1,400-square-foot 4-car garage, a 575-square-foot covered lanai with tongue-and-groove ceilings and summer kitchen rough-in, three tankless water heaters, an LP gas system servicing the cooktop and dryer and ready for a future summer kitchen, and a prefabricated steel utility building for storage or equipment, all set within a peaceful natural backdrop of uplands and mixed hardwood wetlands and conveniently located near top-rated schools, shopping, dining, and major Central Florida commuter routes.
