The thinnest house in the world built between two tower blocks in Warsaw. The house measures 1.2 meters at its widest point and 71 centimeters at its narrowest. The building has been designed by Jakub Szczesny, who took his inspiration from the work of Israeli writer Etgar Keret. The new house is only 1.2 meters, but it comes with a bathroom, a kitchen and a bedroom. Architect Jakub Szczesny said that he designed the two-story aluminum and plastic house three years ago to fill a narrow space between a pre-war house and a modern apartment block in downtown Warsaw. The Foundation of Polish Modern Art and Warsaw Town Hall helped fund the project, which they consider an art work. But it may not be easy for the tenants. The triangular building runs 10 meters deep at the base and stands 9 meters tall. Metal and aluminum pipes hold the structure nearly 3 meters above the ground, and visitors will climb a metal staircase and squeeze through a hole to enter the building. The ground floor contains a toilet and shower, a kitchen with a sink and cupboards, a table for two, and a bean bag sofa. Another metal ladder goes to the second floor, which has a nearly double-size bed, a table and a chair. Szczesny told that the building achieves two goals: filing an empty city space and linking Warsaw's World War II tragedy, when more than half the city was destroyed, with modern buildings that went up afterward. The first tenant Etgar Keret, an Israeli writer whose ancestors died in Poland during the Holocaust, moved to the house. "It is a kind of a memorial to my family," said Keret, explaining that his mother's and father's families died in the Holocaust under Nazi Germany's occupation of Poland, and his paternal grandfather died in Warsaw's 1944 uprising against the Nazis. The structure has been named Keret House after the Israeli writer. He said he only visits Warsaw twice a year, so other tenants will be able to try out the tight quarters of the non-profit building for free, too.

A stunning home on the French Riviera that was once owned by Edith Piaf is on the market for almost US$ 5.25 million. She bought the four-bedroom property in Grasse on the French Riviera in the 1950s and lived there until her death from liver cancer in 1963, at the age of 47. The refurbished property on the south east coast of France is surrounded by countryside, being between the two pretty villages of Mougins and Valbonne. The grounds are extensive and include a tennis court, an outdoor swimming pool and a pool house. In addition, there are three separate guest suites and a two-bedroom guardian's cottage. The landscaped gardens include a lawn area with Mediterranean shrubs, mature trees and enough space for a helicopter to land. Inside of the property, there is a stone archway separating the kitchen and dining room, as well as exposed stone walls in the living area. There is pretty floor tiling throughout much of the house, with wooden ceiling beams and large doors opening out to the garden. Carlton International, the estate agents handling the sale, said: 'The property makes the perfect family home, ideal for entertaining.' It added: 'This was the former home of one of the most famous, internationally renowned french singers of the twentieth century. 'It is a stunning property in the heart of the countryside, enjoying complete quiet.' And buying agent Henry Pryor said: 'Properties with this history are always going to create a stir, especially on the French Riviera. 'The agent's problem won't be getting someone to view it, but holding back the tour buses who would like to see it.

A pioneering 3D-printed house just popped up in Xian, China - and Chinese company ZhuoDa "built" the two-story villa in less than three hours. Made up of six 3D-printed modules, the house was assembled like LEGO bricks before a live audience who were then invited to explore the interior. The modular fireproof home can withstand a magnitude-9 earthquake and is made from a special construction material the company is keeping secret. The company completed approximately 90 percent of the construction in an off-site factory before shipping the modular pieces to the installation site. This efficient and timesaving process dramatically reduces construction costs to just US$ 400 - US$ 480 per square meter. According to An Yongliang, the developing engineer at Zhuoda, the 3D-printed villa only takes about 10 days to produce from initial construction to final assembly, while it typically takes half a year to build a traditional villa. The house is capable of withstanding high-magnitude earthquakes because the modules, each weighing over 100 kilograms per square meter, bear weight independently. The steel-framed structure home can also be filled with heat-insulating materials. The Zhuoda Group has filed over 22 patents on their technology and is keeping their top-secret material under wraps. However, the company's vice president Tan BuYong has revealed that the new material is sourced from industrial and agricultural waste, is fireproof and waterproof, and is free from harmful substances such as formaldehyde, ammonia, and radon. After the structural framework was 3D-printed, the company applied decorative sheet textures to each module before final assembly. Homeowners will be able to choose from a variety of decorative textures, such as jade, marble, wood, and granite. Herbs can even be embedded into the walls of the house for "built-in aromatherapy". The buildings can withstand wear for at least 150 years. On January 2015 a Chinese company WinSun has successfully 3D printed a five-story apartment building and a 110 square meters villa from special print material. China's newest mansion is not only made from recycled materials, but the sprawling 110 square meters home was made with 3D printing. The luxury mansion was 3D printed in layers, using recycled stone and construction waste.
