Design a futuristic floating house concept with the romantic elegance of a 19th-century ship. The home is a sleek, streamlined catamaran structure with soft, flowing curves reminiscent of historical design but optimized for functionality. The main color scheme is white and deep ocean blue, interwoven with large glass panels to allow natural light and expansive views. The windows are solar panels, blending eco-friendly energy solutions with aesthetics. Between the twin hulls, include an underwater room with large glass walls, allowing inhabitants to observe the underwater ecosystem. The home features mast-like structures designed to harness wind energy, adding both charm and practicality. The deck includes a full-sized lawn space, equivalent to a soccer field, for gardening and recreational activities. There’s a small dock extending from the house for water access and docking a compact motorboat. Additionally, design a terrace with comfortable seating for outdoor gatherings. The overall style should be aerodynamic and contemporary, yet realistic and feasible in its construction. Make it appear luxurious but focused on sustainability, energy independence, and a seamless integration with nature.
