5. TRANSPARENT HOUSE (JAPAN)

This house in Tokyo by Sou Fukimoto Architects, known as House NA, stands out with its modern and transparent style. The building is unlike its neighboring houses in its appearance and structure. The interior of the residence has hardly any walls. The house boasts large glass windows for plenty of daylight, but the downside seems to be a lack of privacy. Just about everything indoors is exposed to neighbors and passerby. On the bright side, there are plenty of positive features in this vertical living space to focus on including its sleek, contemporary aesthetic with adventurous appeal. The design appears to mimic a tree without outright copying its appearance. There’s also something about it that has the architectural feel of a bunk bed. I’m guessing it’s all the climbing without actually entering a new room. The three-story edifice features various levels of living space within the segmented structure that’s great to just hang out on, as if you were perched atop a tree branch. House NA is the modern interpretation of an adult treehouse for permanent residence.

4. TOILET SHAPE (KOREA)

The Toilet-Shaped House has a very unique design, and was built by Sim Jae-duck, the chairman of the organizing committee of the Inaugural General Assembly of the World Toilet Association, and he hopes his toilet house will highlight the global need for better sanitation.. The Toilet-Shaped house is in fact named Haewoojae, which signifies in Korean “a place of sanctuary where one can solve one’s worries“. Sim Jae-duck will open what is billed as the world’s one and only toilet house on November 11 to mark the launch of his World Toilet Association. The 4,508-sq-foot structure features four deluxe toilets—one of which includes a misting device that helps users "feel more secure" and electronic motion sensors that lift and lower the lid when needed. And if that wasn't hilarious enough, Sim Jae-duck is letting patrons rent the house for an absurd $50,000 a day. I would take him up on it, but there's no pool. Where am I going to drop the kids off?

3. UPSIDEDOWN HOUSE (GERMANY)

A new cafe in Germany has heads spinning with its wacky upside-down design. Toppels Cafe, located near Frankfurt, opened earlier this year and tourists are flocking to take photographs in the mind-boggling building. Positioned on the roadside in Wertheim, the popular eatery is bound to stop traffic with its dizzying decor. The entire establishment belongs to an (imaginary) family named the Toppels. It’s not just the outside which looks topsy-turvy, inside, everything is upside down as well. Fruit bowls hang down from the kitchen ceiling and you’ll even find a toilet above your head in the bathroom.

2. ROCK HOUSE PORTUGAL

Casa do Penedo, also known as Stone Castle or a Stone House, is an architectural monument located between Celorico de Basto and Fafe, in northern Portugal.Casa do Penedo is translated in English as House of the Rock.

The engineer who built the Casa do Penedo was from Guimarães.The residence was initially used by the owners as a holiday destination. Today, Casa de Penedo is a small museum of relics and photographs from Penedo’s history. The building is located near a wind electricity farm, although there is no electricity inside the house itself. Due to its unusual design and integration into the surrounding nature, the building has become a growing tourist attraction.

1. PAS HOUSE (CALIFORNIA)

The PAS house is the first house designed to be entirely used for skateboarding as well as being a traditional dwelling. The prototype of PAS House was recently presented at La Gaite Lyrique museum in Paris. The house is divided into three separate spaces. The first one includes the living room, dining area and kitchen, the second one includes a bedroom and bathroom and the third one a skateboard practice area. Each space is skateable as the ground becomes the wall then the ceiling in a continuous surface forming a tube of a 10ft radius. The furniture is also skateable, whether it is integrated in the curve like the sitting area, the kitchen or the bathroom or just as standing object like the dining table, the kitchen Island or the bed.
