Design a modern house with a facade that combines three different textures. The first texture should be of a material such as concrete or stone, the second texture should be of a material such as wood or plaster panels, and the third texture should be of a luxurious material such as marble, granite, or tile. The facade should have two contrasting and harmonious colors, such as white and dark gray, or black and light gray. The shape of the house should be modern and minimalist, with straight lines and sharp angles. The house should have a flat roof and large windows that allow in natural light. The exterior of the facade should be surrounded by a garden with green lawn on its entire perimeter, with a clean and minimalist design that highlights the beauty of the house. The lawn should be well-kept and there should be some strategically placed decorative trees or shrubs to add depth and texture to the design. There should not be a pool or swimming pool in the design. The design should be unique and eye-catching, but it should also be functional and practical.
