This 3,200-square-foot apartment feels much larger thanks to inspired changes that maximize ocean-front views in Sunny Isle, Fla. Richly textured with walnut paneling, plaster walls and low, simple-shaped furnishings, this second-home to avid travelers is warm, inviting and easily maintained. A den and dining room were carved out of existing space, giving the illusion of a larger contemporary area, which is used for frequent entertaining.
