Design a modern house with a facade that combines three different textures. The first texture should be a material like concrete or stone, the second texture should be a material like wood or drywall, and the third texture should be a luxurious material like 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 precise angles. The house should have a flat roof and large windows that allow in natural light. The exterior of the façade should be surrounded by a garden with green grass around its perimeter, with a clean and minimalist design that highlights the beauty of the house. The lawn should be well manicured and there should be some strategically placed decorative trees or shrubs to add depth and texture to the design. The design should be unique and eye-catching, but it should also be functional and practical.
