HA-HA, in partnership with BIK Bouw and Wooncompas Housing, will develop four social housing blocks for the community of Ridderkerk, near Rotterdam, Netherlands. The project uses materials from the existing social housing estate, built in the 1950s, and employs an innovative modular-timber system to create sustainable human-centered housing. The old buildings are planned to be disassembled and their components reused and integrated into the new development, which will increase the number of affordable units by 13%.
As the city continues to evolve and transform, dead edges in the cityscape begin to emerge, subsequently reducing the level of activity in our built environment. These 'dead edges' refer to the areas that lack active engagement, they remain empty and deprived of people, since they no longer present themselves as useful or appealing. As the Covid-19 pandemic draws to an ultimate close, the first issue we may face post-pandemic is to revive our urban environment. A kiss of life into a tired and outdated cityscape...
The focal element in creating an active and healthy urban environment is by increasing vitality through placemaking. Creating diverse and interesting places to reside, thrive, and work. Here are five regenerative strategies that animate the cityscape and ultimately produce resilient, attractive, and flexible environments.
While circular economy is often discussed in relation to the architectural object through the lens of material recycling, design for disassembly, and material passports, the framework is most fully enacted at the neighbourhood and city scale. Whether it is visions of circular communities that hint at some level of self-sufficiency or policies set in motion by cities, urban-scale projects exemplify the guiding principles of the circular economy, providing a glimpse into what a fully-fledged version of it might look like. The following explores the strategies used in circular urban environments, from architecture and construction materials to energy production, waste management and food production, as well as the processes and operations that govern these designs, providing insights into the conditions that inform circularity.

Reform and adaptation of spaces represent a significant parcel of projects ordered to architecture firms, and reuse of preexisting structures is not newness. Functions and needs change over time, therefore adaptations are required to meet new demands. However, no matter how much the maintenance of a building is, in most cases, preferred in economic and ecological sense to its demolition and a new construction from the beginning, the logic of the reuse of a space does not usually extend to its parts that become, thus, rubble.
Italian architecture practice Spacelab designed an energy self-sufficient shelter for temporary use, a parametric project that can be built without foundations on any site, leaving no trace and no damage to the site at the end of its life cycle. Named Zero in reference to the lack of waste during construction or removal and its zero-emissions operation, the structure can be demounted and reassembled multiple times, tapping into issues of circular economy, impermanence and reuse.
"For more than a generation, federally funded historic tax credits (HTCs) have been instrumental in incentivizing developers to revive and reuse historic buildings and keep them economically viable, rather than replace them with shiny new objects. These credits create jobs, promote responsible development, and leverage billions in private investment to enable income-generating buildings". Read the interview between Justin R. Wolf and Meghan Elliott, founding principal of New History, a firm specializing in adaptive reuse.

For this year's edition of the Venice Biennale, the Japan Pavilion invites visitors to reflect on the movement of goods fuelling mass consumption and rethink sustainability and reuse in architecture. Titled Co-ownership of Action: Trajectories of Elements, the project curated by Kadowaki Kozo involves dismantling an old wooden Japanese house and transporting it to Venice to be reconstructed in a new configuration with the addition of modern materials. The exhibition exemplifies how old materials could be given an entirely new existence by putting the current movement of goods in the service of reuse rather than consumption.
As levels of pollutant emissions have increased over the years, awareness has also grown regarding actions that can be taken to minimize the damage caused to the planet. As a way to promote waste reduction or prevention, the 3 R's rule is created: reduce, reuse and recycle. These actions, together with sustainable consumption standards, have been promoted as a means to protect natural resources and minimize waste.
The concept of “decarbonization” has been in vogue recently in political speeches and global environmental events, but it has not yet gained enough attention in the field of architecture to profoundly change the way we design and construct the world of tomorrow. Buildings are currently responsible for 33% of global energy consumption and 39% of greenhouse gas emissions, indicating that architects must play a significant role if we are to stop or reverse climate change. With carbon acting as a universally agreed upon metric with which the greenhouse gas emissions of a building can be tracked [1], one of the most important ways through which this goal can be achieved is therefore the decarbonization of buildings.

Commonly used as storage support for products in supermarket stocks and fairs, pallets are versatile. After their primary function has been discarded, the reuse of pallets for other purposes is increasingly common, collaborating to the reduction of the amount of waste discarded, especially as raw material for the creation of furniture and decks. However, going beyond the commonly highlighted DIY furniture tutorials on youtube, these structures are gaining ground as the main element in the construction of ephemeral architecture, such as small pavilions and urban installations. In fact, these small pieces can be stacked and united together in different ways and patterns.
Recycling and upcycling of materials and structures have become more and more popular in architecture as alternatives to the production of components in construction, typically associated with increased energy consumption and high levels of pollutants released into the atmosphere. The main difference between these two methods is that, while the former uses a certain amount of energy to process the material before it is reused, the latter does not require this process, but rather reuses it just as it was discarded.
In Mexico, 40 million used tires are thrown away each year and only 12% are recycled. Tires are a difficult waste product to address, due to the sheer volume produced as well as their durability and the components within tires that are bad for the environment. According to specialists, in Mexico about 5 million tires are recycled in organic products and in the cement industry.
In New York, activists and professionals have been working for many years to try to save 10 decommissioned tanks, from demolition by putting forward alternative usage of these structures. Partnering with STUDIO V, an architectural firm and landscape architects Ken Smith Workshop, they came up with an inventive proposal that reimagines these industrial relics as a 21st-century park, a novelty in the traditional definition and configuration of public spaces.
The need to substantially reduce our impact on the planet must be translated into a significant change to our lifestyle and habits. One of these is to consume responsibly and consider that waste does not exist, but that all material can be transformed into something useful again following a circular ecological system.
In his book Upcycling Wood, Reutilización creativa de la madera, the architect and artist Bruno Sève writes and edits a non-exhaustive guide of the uses and possibilities of recovered wood, as a framework for responsible reuse; from small scale, such as furniture or artists' canvases, to medium scale, with its use in interiors and facades. This book seeks to raise awareness among professionals and citizens in general through analysis of the life cycle, examples of uses and finishing processes, leading to an ecological and responsible framework. The book is illustrated by numerous design and architecture teams who follow the guidelines of ecological design with reclaimed wood.
Vincent Callebaut Architectures has envisioned a radical underwater colony for "climate change refugees" 3D printed from recycled materials taken from the ocean's floating garbage patches. This particular proposal of "oceanscrapers" is sited off the shore of Rio de Janeiro. It's aim is to provide a sustainable habitat with 10,000 housing units, office and work space, sea farms, gardens, community orchards and much more, while fostering marine life.
