Notre Dame Cathedral reopened on December 7th, 2024, welcoming visitors for the first time since the 2019 fire. The restoration of Notre Dame Cathedral was a massive undertaking, led by chief architect Philippe Villeneuve, assisted by Rémi Fromont and Pascal Prunet. The project involved approximately 2,000 craftspeople, 250 companies, and about $900 million, demonstrating the immense scale and complexity of the work on a tight deadline. Despite the major milestone of opening before the end of the year, the restoration works are not yet complete, as they are scheduled to continue through 2026.
Throughout the modern era, pavilion architecture has consistently reflected cutting-edge architectural trends. These temporary or semi-permanent structures, often featured in exhibitions, fairs, cultural events, and sports gatherings, provide a platform for exploring new materials and design concepts. Pavilion designs are intended for easy assembly and disassembly and are typically used for short durations, making it crucial to consider reducing environmental impact without sacrificing aesthetics and innovation. In this endeavor, wood emerges as a key ally.
After a three-year break, Hello Wood’s builder festival returns to welcome students, architects, and young professionals from all across the world to join the 10-day builder camp to test their wooden construction abilities, learn to collaborate, and participate actively in on-site design and construction. For the first time in Hello Wood’s 13-year history, this year’s workshop takes place at a new location, in the crater of an abandoned basalt quarry on Haláp Mountain in Hungary. The workshop also aligns with and supports Veszprém’s title of 2023 European Capital of Culture, which also includes over a hundred other villages and towns across the Bakony-Balaton region. The event took place between July 6 and 15, ending in a two-day music festival open to all.
Shigeru Ban has just launched the office’s most recent project in Nieuw Zuid in Antwerp, Belgium. Named Ban, after its creator, and in collaboration with Bureau Bouwtechniek, the complex puts in place a 25-story residential tower and a separate building, creating a total of 295 residential units. During the breaking ground ceremony, the architect also inaugurated an exhibition of images highlighting his humanitarian work in conflict and disaster areas, in near proximity to the construction site.
American architect Brian Mac grew up near Detroit. He graduated from the Architecture School at the University of Detroit in 1988 and for the next five years worked for a preservationist firm, Quinn Evans Architects in Ann Arbor. There he learned to love historic architectural detailing, and, while working at the firm, in 1992, became a licensed architect. Then followed a short period of disillusion with the profession and moving to Ohio to work in a residential treatment center for adolescent felony offenders.
Stilt houses are houses raised on piles over the surface of the soil or a body of water. Dating back to the Neolithic and the Bronze Ages, a wide variety of raised dwellings have been identified in a variety of forms worldwide, designed with several diverse and innovative methodologies. Stilt houses are well suited to coastal regions and subtropical climates. More than just a distinctive structural design resolution, they also protect against floods, maximize views and allow homeowners to build on rocky, steep, or unstable land. They also serve to keep out animals and vermin, provide ventilation from underneath, and minimize a house’s ecological footprint.
Mad Arkitekter and Mud Landscape Architects, have won the international competition to design a vertical city quarter in Kreuzberg, Berlin. Selected from 14 submissions of well-known European architecture firms taking part in the contest, the proposal re-interprets the district in a vertical configuration. Set to be 98 meters high, with 29 floors, the Woho project will become Germany's tallest three-hybrid construction, once completed.
3XN and IttenBrechbühl have been selected to design Tilia Tower, an 85-meter-tall mixed-use wooden building that includes apartments, retail, and a hotel. Located in Lausanne, Switzerland, the project also encompasses the transformation and renovation of two existing buildings, as well as the implementation of new public spaces, bringing vitality to the neighborhood.
From its starting to point as a tree to its product form as a beam or piece of furniture, wood used in architecture and interior design goes through several stages and processes. A renewable resource and popular traditional building material, wood is also often cited as a promising construction material of the future, one that is suitable for the new demands of sustainability. But unlike concrete, whose molds can create even the most complex curves, wooden architecture most commonly uses straight beams and panels. In this article, we will cover some techniques that allow for the creation of curved pieces of wood at different scales, some of which are handmade and others of which seek to make the process more efficient and intelligent at a larger scale.
Open Platform (OP) and JAJA Architects, together with Rama Studio and Søren Jensen Engineers, have won the open competition for a new parking house in Aarhus. In line with Denmark’s vision of becoming climate neutral by 2050, the structure will be the country’s first wooden parking house.
Located in Elbbrücken, a peninsula neighborhood within Hamburg's HafenCity, Wildspitze will add 189 residential units on its riverside site. Each apartment will feature a loggia behind a double glassfacade.

The key to engineering wood strong enough to support skyscrapers may lie in the interaction between molecules 10,000 times narrower than the width of a human hair.
A new study by researchers at the Universities of Warwick and Cambridge has solved a long-held mystery of how key polymers in plant cells bind to form strong, indigestible materials such as wood and straw. By recreating this ‘glue’ in a lab, engineers may be able to produce new wood-based materials that surpass current strength capabilities.
Nowadays the main building materials used in the construction industry are concrete, steel and timber. From the point of view of ecological sustainability, there are four important differences between these three materials: first, timber is the only material of the three that is renewable; second, timber needs only a small amount of energy to be extracted and recycled compared to steel and concrete (but the implementation of its potential is not as developed yet); third, timber does not produce waste by the end of its life since it can be reused many times in several products before decomposing or being used as fuel and; and fourth, timber traps huge amounts of carbon from the atmosphere – a tree can contain a ton of CO2 [1] – and the carbon absorbed remains embedded as long as the wood is in use.
Considering the fact that 36 percent of total carbon emissions in Europe during the last decade came from the building industry,[2] as well as 39 percent of total carbon emissions in the United States,[3] the materiality of construction should be a priority for governments’ regulations in the future as measurements against global warming. The amount of CO2 in the atmosphere and the level of carbon emissions of the big economies across the globe are big issues that need to be solved with urgency in order to avoid larger, more frequent climate catastrophes in the future. The current regulation in several countries of the EU, which is incentivizing the use of renewable materials in buildings, is showing the direction the building industry in many other parts of the world should follow. And if these measures are adopted across the EU and beyond – if other countries start to follow this tendency as well – there will be significantly more wood in cities.
Building on these precedents, Hawthorne predicted that after years of baroque parametricism, in 2015 architects would use last year’s meditations on history as a practical foundation for new projects and proposals. An example of this can be found in the work of Michael Ryan Charters and Ranjit John Korah, a duo who recently shared the top-five prize for the CAF led ChiDesign Competition (part of the Chicago Architecture Biennial) for their project Unveiled. In a brief that called for “a new center for architecture, design and education,” and with lauded jurors including Stanley Tigerman, David Adjaye, Ned Cramer, Monica Ponce de Leon, and Billie Tsien, Charters and Korah proposed what could casually be summarized as a terracotta framework over a multi-story crystalline form of wooden vaults, but is actually something much more complex.

Among the changes in material technology that are constantly altering the architectural landscape, one of the most popular - and most dramatic - is the idea of the timber skyscraper. And with vocal advocates like Benton Johnson of SOM and Michael Green leading the discussion with projects like the Timber Tower Research Project, the wooden highrise is on the verge of becoming a mainstream approach.
To further the conversation in the USA, the US Department of Agriculture, working in partnership with Softwood Lumber Board (SLB) and Binational Softwood Lumber Council (BSLC), has recently launched the Tall Wood Building Prize Competition, an ideas competition with a $2 million prize. To find out more about tall wood buildings, we caught up with Oscar Faoro, Project Manager of the competition. Read on after the Break for our interview and more details on how to enter.
While interest in tall timber buildings continues to grow, there still remains one obvious concern: combustibility. So how safe are timber structures really? Arup Connect spoke with Robert Gerard, a fire engineer in Arup’s San Francisco office, to find out how high-rise wood buildings take fire safety into account.
