The continuation of remote work practices has altered cities' bustling downtown areas along with the traditional office landscape, leaving behind many vacant spaces whose future purpose is a matter of speculation. Four years after the onset of hybrid working policies, office occupancy rates in urban centers remain lower than pre-pandemic levels, signaling a long-term shift in the work environment. Some developers have aimed to reposition these buildings while other are seeking alternative uses of vacant buildings in central location. While both approaches prove beneficial in their own ways, the potential for repurposing office buildings is vast and exciting. From residential living to cutting-edge research facilities, architects and developers explore diverse possibilities and challenges of transforming these underutilized structures into thriving new spaces.
Selected by ArchDaily as one of the Best New Practices of 2024, IDK is injecting a fresh and dynamic approach to building communities with quality architecture. Mike Lim, James Pockson and Roddy Bow met while studying for their master's degree in Architecture at the Royal College of Art (RCA and founded their architecture practice, IDK in London in 2019. The three, driven by a strong mission, to help communities and progressive institutions, organizations and cultures thrive – have been researching and delivering community-oriented projects that embody experimental building with a holistic approach. Their work focuses on nurturing social development, with an emphasis on ecological awareness, local material use, smart resource and budget management, respectful refurbishments, and designing only what is necessary without "over-building."
The use of wood in Chilean house construction reflects the utilization of a renewable resource available in the country. Moreover, it can be an extremely sustainable material when produced and processed under certain conditions, as it can have a very low carbon footprint. It is characterized by its warmth, resistance, and durability as a construction system.
In 1853, at the New YorkWorld Expo, a man climbed onto a suspended platform and ordered the rope supporting it to be cut. He dropped a few inches, but the safety system activated, and the platform remained stable, to the delight of the watching crowd. At that moment, perhaps not even Elisha Graves Otis realized how his invention would permanently change the course of architecture.
Located in Mexico City, the municipality of Iztapalapa has some of the most densely populated areas within the metropole. Serving a population of 1,800,000 people, many of them with lower incomes, the municipality struggles to provide sufficient public spaces and amenities. In an effort to correct this, the administration set out to take underutilized and abandoned plots of land and transform them for public use. Utopia Estrella is one of these initiatives. Located near Mexico City’s largest water treatment plant, the project combines a socially engaging architectural program with a pedagogical approach to the role of water infrastructures in the larger ecosystem. Designed by Cano Vera Arquitectura, the project has been recognized as the Gold Prize Winner of the Holcim Awards 2023 for Latin America. In a video interview for ArchDaily, Juan Carlos Cano of Cano Vera Arquitectura discusses the impact of this project, its goals, and the unique conditions that led to its development.
3XN GXN has revealed its design for Mahler 1, a 15-storey mixed-use office building. The structure, developed in collaboration with Victory Group, Icon Real Estate, and Erik Dhont Landscape Architects, features a hybrid-timber construction system that creates a stepped volume, breaking down the building’s mass. At the street level, the development offers a wide variety of public amenities, striving to become an active hub for both residents and office workers. The project is expected to begin construction in the first half of 2025 and conclude in late 2027.
Organizing, shaping, stacking. Transforming raw materials from the soil into architecture. This is a challenge that many Latin American architects embrace, demonstrating that scarcity can be daunting but also a rich opportunity to unleash creativity.
The use of materials extracted from the local soil serves a dual purpose. In regions with limited industrialization, using locally sourced materials makes economic sense because industrial materials such as concrete and steel are expensive and often require long-distance transportation, adding to their cost. Environmentally, choosing locally sourced materials from the start of a project reduces transportation needs and carbon emissions, supporting sustainability efforts.
Many ancient Egyptian, Greek and Islamic religious buildings share a common feature known as hypostyle. Defined as rows of columns that support a roof, this solution has developed in different cultures in different periods of time, which can explain the variety of materials, shapes, sizes and distances between the columns that can be found around the world. Famous examples of the use of this concept are Great Hypostyle Hall (c. 1290–1224 BC), part of the Karnak Temple Complex and one of the most visited monuments of Ancient Egypt, and the Wooden Hypostyle Mosques of Medieval Anatolia (c. 13th and mid-14th centuries), World Heritage Site located in present-day Turkey.
In contemporary architecture, it is possible to see different kinds of examples of how this concept is revived. While some projects use the concept to refer to vernacular architectures that correspond to the same program and use as the proposed building, as is the case with some mosques, others rely on the abstraction of the term through an interpretation that highlights the pillars and their organization in the proposition of the space. In all of them, however, it is clear that the relationship between the hypostyle inspiration and modular architecture is very close, practically intrinsic.
Surface preparation is crucial in ensuring the longevity and effectiveness of coatings in construction. In fact, studies show that up to 80% of premature coating failures can be attributed to inadequate surface preparation. These failures typically manifest in the form of peeling, blistering, and cracking, which diminish a building's appearance and compromise structural integrity.
Building façades are highly visible and exposed and bear the brunt of environmental factors. Poor surface preparation has a direct impact on the long-term performance and appearance of façade finishes, which can in turn suffer from accelerated degradation, necessitating frequent maintenance and repairs.

In many cases, when working on a renovation project within an old building, architects often encounter segmented floor plans, spaces without natural light, and complex layouts that hinder the seamless flow required in modern living. Consequently, architects typically opt for targeted demolition, removing specific walls during renovations. This solution can address several of the problems encountered but demands meticulous planning to ensure the structural integrity of the building. When it comes to scenarios like these, structural reinforcement is one of the most commonly employed methods.
Seratech's technology, developed by Sam Draper and Barney Shanks, eliminates the CO₂ footprint of concrete and reduces carbon emissions in construction. This innovative process uses silica, a waste product from flue gases, as a carbon-negative cement replacement in concrete. By incorporating silica, the required amount of Portland cement is reduced by 40%, resulting in the production of carbon-negative concrete. This groundbreaking technology won the 2022 Obel Award for its focus on embodied emissions.
The Obel Award is an international award that promotes architecture in the service of both people and the planet. Seratech was the fourth winner of this new international prize for architectural achievement, preceding this year's 'Living Breakwaters' by SCAPE Landscape Architecture. ArchDaily had the chance to interview Sam Draper, CEO of Seratech, about the company's role in building a sustainable construction industry and their plans for scaling their innovative process.
By the time I was 17 years old, I had moved 11 times. Because of my own experience relocating from one place to another, I’ve spent the better part of the last several decades focused on making sure that everyone has a place to call home, that everyone enjoys the human right to housing. But it was not until my time at Enterprise Community Partners, a nonprofit focused on community development and affordable housing, that I realized the methods and materials we employ to realize that human right matter.
