Along Australia's rugged western coastlines, landowners could one day live next to their cliffside properties -- rather than on them -- if the designers of this vertigo-inducing, prefabricated design, Modscape, have their way.
Built onto the the side of a vertical rock face like a modern Mesa Verde dwelling, the obviously-named Cliff House melds modular construction with a vertical floorplan. Each floor of the home bolts into its neighbours via a series of steel pins, and then are anchored to the side of the cliff with support beams. The entryway sits at the cliff's edge -- residents descend through the home via stairs or an elevator -- while the lowest floor, terrifyingly, opens onto a deck area replete with a barbecue and jacuzzi.
The unit is still entirely a concept, but according to its architects it was created in response to their clients' demands for unique cliff-based homes, so there might just be enough demand to warrant actually building a few. Just don't let Mel Gibson in a pickup truck anywhere near that thing. [Modscape Concept via Inhabitat]
