Generate a series of hyper-realistic images of modern house facades approximately 7 meters wide. Each house should be two stories tall, featuring a balcony and a covered garage. Ensure the slope of the vehicle access ramp is accurately represented. The facade should include dark gray cantera cladding on some walls, with the remaining walls painted in white. Incorporate steel elements where appropriate. The flooring should be concrete with green grass separations. In the background, include tall modern buildings, green mountains, a blue sky with occasional clouds, and birds soaring through the air
