Upside down houses are becoming increasingly popular tourists sight, creating fascination and interests in both construction and design. We look at some of the builds which have attracted thousands of tourists and will continue to influence future builds.


Built in 2008 within Transsenheide, architects Klaudiusz Golos and Sebastian Mikiciuk have created an iconic place for tourists within the area with their vision of an upside down house.

Visitors can view ordinary items ‘upside down’, with the loo seat in the bathroom based on the ceiling, alongside beds, chairs and other household items, creating interest and wonder.


Open all year round, the upside down house within Szymbark is built on a tilt, where visitors enter the building through one of the windows and walk on the ceilings.

Designed by Daniel Czapiewski, the timber structure took longer than traditional builds, with the foundations requiring increased levels of concrete. The build also incorporates propaganda from the 1970s, reflecting Poland’s communist history, signifying a key political message both in subject and construction.

Situated nearby is the world’s longest plank, the Centre of Education and Regional Promotion, the Museum of Carpentry and House of the Siberian.

Following on from Poland’s upside down house, Daniel Czapiewski supported the construction and build of another upside down house, this time in Niagara Falls.


The Rumah Terbalik, situated in Tamparuli was one of the first upside down houses within South East Asia, becoming a popular public site in 2012.

The build has been added to the Malaysia Book of Records. A multitude of tourist facilities have since been built nearby.


Recognised as one of Phuket’s top 5 landmarks, this upside down house uniquely showcases a 3,100 square foot garden maze, ideal for families as they visit this unusual build.

Originally designed to represent a Tibetan-style home, the upside down house, built in 2007 is popular with both children and adults through providing fun and adventure suitable for all ages.

Webuild and Lane to build railway in Texas

2 min
Italian construction firm Webuild and its U.S. subsidiary Lane Construction sign a US$16bn contract to build a railway in Texas

Webuild, formerly known as Salini Impregilo, has announced a US$16bn agreement to build a high-speed railway between Dallas and Houston in Texas. The project has been described as the “final step” before financial closure for the company, which Webuild said was“foreseen in the coming months”. 

Passengers using the 236-mile long railway, which was developed by Texas LLC, will travel in Japanese Tokaido Shinkansen bullet trains at 200mph, making one scheduled stop at Brazos Valley near Texas A&M University. This aims to shorten the total journey time between the two terminals from almost four hours to around 90 minutes, Texas LLC claims. The company hopes commercial operations will begin in 2026. 

According to Webuild, the new line will aim to target an estimated 100,000 “super commuters” who travel between the two cities by car and plane every week. Webuild said it would cut greenhouse gas emissions by up to 101,000 tonnes per year.

This contract is an update on a preliminary design-build agreement signed with Texas Central LLC in 2019, valued at $14bn. The deal confirms the US as Webuild's single biggest market, comprising some 35% of the group’s total order backlog.

Around 17,000 new direct jobs will be created as a result of the project, as well as 20,000 indirect ones. U.S. suppliers from states aim to provide an estimated US$7.3bn of materials to construct the railway in conjunction with services provided by Italian suppliers. 

Webuild and Lane will oversee the civil engineering works of the project. This includes the tracks themselves, the viaducts, and depot buildings. 

Three facts about bullet trains 

  • The fastest commercially operated bullet train is not in Japan, but China. It is capable of reaching speeds of up to 268mph… with passengers onboard. 
  • Bullet trains are one of the safest ways to travel. Over 10bn passengers have been on board a bullet train and no-one has ever been killed on one. 
  • The “tunnel boom effect” is powerful enough to blow a freight train over. When a bullet train exits a tunnel at over 200mph, the resulting sonic boom effect is so strong, it could blow a normal freight train off its tracks.
