Although you might expect it to be called something referring to simple geometry, the award-winning and highly angular Klein Bottle House in Rye, Australia—a coastal town about 50 miles south of Melbourne—is instead named after a paradoxical math concept.
Just as with the geeky 3D conundrum it gets its moniker from, the house wraps back into itself, in this case via a windy red staircase. So now that we're past the etymology, let's take a closer look at the architecture.
After passing by bedrooms and creating an internal courtyard, the eponymous spiral stairs land in the spacious great room, with slanted walls, vaulted ceilings (in a few directions) and a nice, open wood-paneled terrace overlooking the hillside.
Though built into the side of a heavily treed, sandy hill that probably affords some magnificent vistas of Australia's southern coast, this building's interior and exterior probably provide as many fascinating views. From a short distance, the structure appears to resemble an intricate piece of origami. And inside, one can't help but gaze at all the shapes created by its various folds and intersections.
Because the structure itself offers so much charisma, less is definitely more when it comes to the furnishings. What might look sparse and underdone in a typically flat and rectangular flat is just enough in this multi-dimensional dwelling.
The angularity also lends a different personality to each room. That, along with an interesting mix of materials used throughout, gives this building a gestalt character that's completely unique.
