1.2 meters is the maximum width of a real house called Keret House, located in Warsaw, Poland. That's right, only 1.2 m. You don't look wrong. So narrow that it simply frying your hand to touch the walls. Going from end to end is like a narrow slot between two buildings. Some even compared it to a matchbox. Because the feeling inside is strange and strangely cozy. This home is essentially designed as a piece of art to maximize the dead space between two old buildings, and although it feels tight, there is still plenty of room for living, even a different style.

If you want to have a similar version in Central Europe, the amount you will spend could be up to 120,000 - 150,000 US dollars. A considerable figure for a space that requires calculation when turning. But Keret House is just the starting point on an interesting journey that takes us to the world's super-thin but extremely expensive homes. These are not just weird works to look at for entertainment, but proof of limitless creativity, where every square centimeter of land is used to the fullest. Where narrow space becomes a unique advantage, and where thinness makes people spend a lot of money.

List of the strangest works in the world.

The first is the Flatiron building (New York, America) : take a trip to Mahattan, where the Flatiron building looks like a giant ship turning the waves in the heart of the city with a native racer of only 6.5 million. Completed in 1902. This 22-storey building was once one of the tallest buildings in New York City, with a strong steel frame designed to take advantage of the odd triangle section at the intersection of 23rd and Boulevard. While Flatiron is still not an ideal location for those who enjoy a wide space to dance, it is still an investor's dream.

The second is Steinway (New York, America): driving through the bustling streets of Mahattan, we come to the Steinway Tower, a building like a needle in the sky with a width of 16.8 m, making it one of the thinnest residential buildings in the world. Completed in 2016, this 60-story tower is a symbol of luxury, with each floor containing just one or two luxury apartments, priced at US$18 million or more. Not to mention the monthly management fee to ensure you buy a good car.

The minimalist yet sophisticated design with floor-to-ceiling glass windows brings impressive panoramic views to Central Park. But living at an altitude of 400m, where the wind can make a building shake, it is true that the experience of living in a pencil can sway.

The Steinway Tower may be the dream of the American elite, but across the Atlantic in London there is a delicate house that makes people exclaim with its magic. Next comes Thin House (London, England). Flying across the English Channel we arrive at Thin House in pricey South Kensington, where the thinnest part of the house is just 1.8m wide, looking as if someone had taken a giant knife and cut an ordinary house in half. Built in the late 19th century, it was originally a stables but was later converted into a fully furnished living space with a living room, kitchen and tiny bedroom. The estimated cost is £1.5 million. A figure that makes many exclaim that it would be cheaper to sleep on a park bench. But with property prices in London where every square meter of land costs more than gold, Thin House is still a bargain. This tiny home is not only captivating in its eccentricity, but it's also a testament to how to make the most of space in a super-expensive city.

While narrow houses may be the epitome of space saving in the UK, in Poland an even narrower home is pushing the boundaries of creativity. Karet House (Warsaw, Poland). Heading to Warsaw, we admire Karet House, which has been called the narrowest house in the world, with a maximum width of 1.2 m and the narrowest point of just 70 cm. Designed by Jakub Szczesny in 2012, the house is sandwiched between two large buildings, using space that no one thought could be built. Inside, everything is as minimalist as possible. A toy fold-out bed, a tiny desk, and a bathroom where you have to dance to shower without hitting your head on the wall.

This is not an ordinary house, but an art project where short-term artists post to find inspiration. The value of the Carriage House lies not only in the number of hundreds of thousands of dollars, but also in the story that inspires the impossible into reality. Polish users joke that life here is like 24-hour yoga because you have to continuously bend to move.

If the Carret House is evidence of creativity beyond the limit of Poland, in France the building brings an artistic perspective that is the Erwin Wurm House (Le Havre in France). Arriving at Le Havre France, we will meet Erwin Wurm House, a work that is not a house, but a sculpture by the Austrian artist Erwin Wurm. With a width of about 2.5 m and a length of almost 6 m, a curved shape, distorted as if someone was being squeezed. This house looks like it came out of an animated movie, displayed as an outdoor art exhibit.

Erwin Wurm's house attracts thousands of visitors every year who are willing to pay to have their photo taken with this dancing house. Its value lies not in real estate, but in its cultural impact as it gets people thinking about the concept of housing and living space. The estimated cost of this project is around 200,000 euros, equivalent to more than 215,000 US dollars, mainly due to its artistic uniqueness. To live in a house like this, you'll probably need a dose of giddiness and a super artistic soul. Erwin Wurm's house is an architectural joke in Europe.

The creativity in Japan is amazing. This is a waterfront house in (Shiga, Japan). Crossing the ocean to Shiga Japan, we stayed at the Promenade House, a house with a width of only 2.7 m but lasting up to 27 m. Like an endless corridor than a regular house. Designed by Kouichi Kimura Architects; Promenade House takes advantage of natural light and open spaces to create a feeling of spaciousness. Can you touch both walls if you are frying. The interior is laid out simply, with rooms connected together like a walkway as its name suggests. The estimated price is several million dollars thanks to the smart design and prime location. Living here, you can feel Japan's creativity to turn limitations into opportunities.

In addition, in China and Japan, thin houses such as paper also caused fever. In Thach Gia Trang, Ha Bac, China. The 16-storey triangular building is only the thinnest of 2 m, called by local residents. In Tokyo, Japan, the trapezoid with its thinnest spot is only as wide as a person's shoulder, drawing attention thanks to its bright yellow tiles. Also in Japan, a pancake or Kamenori with an area of ​​several square meters looks like a paper model rather than a solid house.

These small structures are worth millions of dollars due to their location and uniqueness, proving that sometimes fragility is also a form of luxury. Despite their small size, these designs are fully equipped, optimized down to every centimeter, forcing anyone who looks at them to admire an incredible ingenuity, fragile but still enough to empty the buyer's wallet.

These ultra-typical houses are not only a place, but also a symbol of creativity, challenging all limits of space. From the towering Steinway Tower in New York to the tiny Carriage House in Poland, each project tells a different story for us to marvel at and chuckle at the wonder of human imagination.
