Set on 1.25 acres, this builder's home displays many custom features, including detailed moldings, tray ceilings and French doors. The 3,450-square-foot postmodern style has a "nice open feeling," says the listing agent.

The living room, which has a cathedral ceiling and skylights, opens to the formal dining room through two sets of French doors that anchor a dual-sided fireplace. Wood floors, radiant heat, a third fireplace, recessed lighting and a high-end kitchen are among the details.

The master suite is one of four bedrooms, and it has an exercise room, his and hers bathrooms and a private deck. There are two other bathrooms in the house. The gated property is reminiscent of a botanical garden, the agent says, noting there is room to add a pool or a tennis court. Frank Mann, Charles Rutenberg Realty, 631-514-4960.
