For those looking for a very expensive unique home, check out this driveway art gallery transformation by Polish architectural firm KWK Promes. The architectural company designed a single family home with the driveway as the main spectacle.
In this model, cars are designed as a main means to navigating through the home (as opposed to a parking garage). The construction of the home was for the car and art lover. The house features a south end entrance and a subterranean tunnel that runs under the garden and directly into the house. The walls of the driveway are then decorated with the owner's art.
The house is separated as two levels and the second level can be reached by climbing the hill. The mansion is covered in green grass (on the roof) to make it appear as a garden and a part of the natural surrounding.
