The use of glass within building work has been utilised for centuries. However, we look at 6 iconic buildings made predominately out of glass, which attract both tourists and locals through their unique designs and intricate facades.

The Gherkin, London

Also known as St Mary Axe, the Gherkin is one of the most iconic skyscrapers in the world.

Completed in 2003, the office building incorporates 41 floors, with a restaurant and bar on the 39th and 40th floors, offering panoramic views of the London skyline.

Built by Skanska, the building has won a multitude of awards, winning the 2004 Riba Stirling Prize a year after its construction.

National Theatre for the Performing Arts, China

Encompassing three performance arenas, the Opera Hall, Music Hall and Theatre Hall, the National Theatre for the Performing Arts in Beijing is 46 metres high and can seat over 5,000 people comfortably.

Completed in 2007 and designed by French Architect Paul Andreu, the glass and titanium dome is enclosed by a man-made lake, which guests must walk over upon arrival, in addition to being the deepest underwater structure in Beijing.

The Louvre Pyramid, France

Constructed in 1989 and designed by Chinese-American Architect I. M. Pei, the Louvre Pyramid in Paris has become an iconic landmark.

The 21 metre glass modern structure is popular with locals and tourists, encompassing the Louvre Museum and is now under internal reconstruction in order to cater for the increased number of visitors.

Botanical Garden, Brazil

Founded in 1808 by King John VI of Portugal, the Botanical Garden, situated in Rio de Janeiro is one of the world’s “most important research centers in the fields of botany and biodiversity conservation.”

Containing over 6,000 diverse flora and fauna, the gardens also ensure the preservation of unique flora and fauna.

Dancing House, Prague

Completed in 1996, the Nationale-Nederlanden Building, otherwise known as the Dancing House was constructed upon an area destroyed by the bombing of Prague by the USA in 1945. The build was a joint venture by Croatian-Czech Architect Vlado Milunic and Canadian-American Architect Frank Gehry.

The unusual design is known to reflect a couple dancing together. The construction needed 99 concrete panels in order to build and maintain the unique structure.

Incorporating a restaurant and bar, providing views of the city, the deconstructivist building is iconic within Prague and is popular with locals and tourists.

High-heel Wedding Church, Taiwan

Situated within Taiwan, the High-heel Wedding Church was completed in January 2016 at a total cost of $686,000, boosting the local economy.

Under the Southwest Coast National Scenic Area Administration, the 55ft church can hold up to 100 guests and took only two months to construct, with 320 fragments of tinted blue glass.

Built for weddings and photoshoots, the church will otherwise not be accessible for religious services.

Why are steel prices on the rise?

3 min
The cost of steel is rising, particularly in the US. We take a look at the situation to find out why.

Steel is an essential material for all businesses in the construction industry. From cars to buildings and everything in between, it is a valuable resource but, as recently discovered, it is also becoming more expensive, especially in the United States. But why is this?


COVID-19 is the biggest cause of the rise in steel prices. The pandemic, in turn, has disrupted supply chains meaning steel as a material could not be shipped to construction sites, and that resulted in a higher price. However, once the height of the several lockdowns subsided, the price of steel remained high, even though those in the US steel industry expected it to drop. 

According to the American Iron and Steel Institute (ASI), the US steel capacity utilisation rate has “remained at or above pre-pandemic levels of 80pc” for the last three weeks. This suggests that there is more steel available for buyers in a previously supply-constrained market.

During this time, the US Midwest hot-rolled coil (HRC) assessment by Argus Media increased by 2pc, or US$33.75/short ton (st). According to Argus, this is similar to a typical pre-pandemic price increase, which was US$40/st when announced by steelmakers. This price hike, which has seen steel costs quadruple since August 2020, continues onwards, leaving many people in the industry wondering what will happen in the future. 

However, according to Argus Media, the Indiana-based electric arc furnace (EAF) minimill steelmaker Steel Dynamics (SDI) expects “post record profits” in the second quarter and that continued demand and "historically low flat roll steel inventories" will lead to even stronger third-quarter results.

Currently, though, the high steel prices mean that very few construction companies are looking to restock their supply of the material, meaning a delay to certain projects. 

The automotive industry

One industry that’s been negatively impacted in particular is the automotive sector. Carmakers in North America have been dealing with disruption to their semiconductor production line for almost half a year, resulting in volumes at some steel processors being significantly reduced. In finding a solution, some car manufacturers, such as Ford, have looked at the idea of idled auto production online, although this is still in the early stages of development. 

According to Cox Automotive,1.78mn new vehicles were manufactured in coming into June which is only a 35-day supply, and one of the lowest levels of production in history. By comparison, new car inventory was at 2.24mn at the end of April 2021. 

This could mean automakers’ demand for steel reduces if the price remains, further constricting the spot steel market. It is clear that the rising price of steel is having a substantial impact on the industries that rely on it. 

Fossil-free steel rolling 

Partnering with Ovako, Volvo, Hitachi ABB, and H2 Green Steel, Nel ASA has today announced that it is planning a fossil-free hydrogen facility for steel rolling and milling operations in Hofors, Sweden. 

The conversion to green hydrogen in the production process aims to reduce CO2 emissions from the facility by 50% from current levels with possibilities for future development of hydrogen infrastructure for transportation, the company said. 

The initiative will focus on developing a fossil-free steel production facility, with the intention of taking the first step towards creating a future hydrogen infrastructure for the transport sector. The investment of approximately SEK180mn is supported by the Swedish Energy Agency via the Industriklivet initiative and will create significant benefits for the wider society from multiple perspectives.

Jon André Løkke, Chief Executive Officer of Nel ASA, said: “"We will work collaboratively together to make this project a success, based on the joint learnings we will standardize the overall solution and ensure that this can be replicated in different locations all across Europe”.
