Despite their whimsical appearance, treehouses offer a unique platform for structural innovations and design explorations. Traditional treehouses rely on the trunks of trees for structural support, but, in order to ease the load supported by the tree, contemporary projects often introduce additional systems, such as stilts to maintain the image while offering additional support. One of the key advantages of elevating them in this way is the reduced environmental footprint. Treehouses can be designed to leave the forest floor untouched, preserving small-scale ecosystems. By freeing up the ground below, they minimize disruptions to native flora and fauna, allowing nature to thrive undisturbed. Similarly, many architects use the local topography to create seamless connections, incorporating ramps, stairs, or bridges that integrate with the landscape. These solutions not only improve accessibility but also enhance the overall experience creating an architectural promenade that moves between the treehouse and its surroundings.

"This sensitivity to the environment is reflected not only in the structural design but also in the careful selection of materials. The use of natural materials like wood, also helps the structure blend with its environment. Some designers have gone further by employing alternative materials such as mirrored panels to reflect the surrounding forest and mask the treehouse's presence entirely, demonstrating that the choice of material can contribute to creating a project that feels like an extension of its setting rather than an imposition on it. This collection highlights notable examples from Sweden, Denmark, Indonesia, and France, showcasing their diverse approaches.

Artificial intelligence (AI) is reshaping the architectural landscape, offering tools that enhance creativity, streamline workflows, and redefine design processes. From assisting in urban planning to conceptualizing homes and creating visualizations, AI is unlocking new possibilities for architects, designers, and even non-professionals. Yet, as AI-generated outputs become more prevalent, concerns emerge regarding the possibility of generating generic-looking designs or the disappearance of traditional design skills. These challenges lead us to critically examine how AI complements human creativity and the ethical implications surrounding authorship, originality, and intellectual property rights in this rapidly evolving digital era.

A look at most of the cities within Latin America reveals striking commonalities across countries, from Mexico down to Argentina: most cities have a well-defined area known as "El Centro" (The Center), anchored by a main plaza (Plaza Mayor), flanked by a church on one side and key buildings like the city hall on another. This is no coincidence, as it can be traced back to an urban planning system established during the Spanish colonization of the Americas in the 17th and 18th centuries. It gave standardized guidelines for city design across its viceroyalties. Unlike French and English colonies, Spanish settlements adhered to regulations that contributed to the emergence of a shared urban identity, with cities displaying similar spatial logic and architectural cohesion despite differing scales and contexts.

In Canada, the tradition of owning a secondary home in the countryside is a deeply rooted aspect of the national culture. In Ontario and parts of the Maritimes, these nature-surrounded secondary homes are often called "cottages". In British Columbia, Alberta, and Saskatchewan, the term "cabin" is more common, while in Quebec, they are known as "chalets." Regardless of what they are called, these rural retreats offer Canadians an escape from urban life, a place to gather with friends and family, reconnect with nature and enjoy outdoor activities throughout the year.

Greenways, as a typology of urban design, have become an essential element in the planning of modern cities. They emerge in response to the increasing fragmentation of urban landscapes by elements such as highways. They usually integrate natural and constructed spaces, providing much-needed connections across various parts of the city. At the same time, they promote pedestrian accessibility, recreation, and social interaction. The Rose Kennedy Greenway in downtown Boston, United States, exemplifies this human-centered approach to design. The project, which began construction in 1991, showcases the potential of greenways to reconnect urban environments and enhance community life. As a series of parks designed by various architecture firms, it aims to create physical links and meaningful spaces that foster social development and a sense of place.

Canada's climate is known for its dramatic contrasts, ranging from frigid winters to hot summers. Large metropolitan areas such as Toronto, Montreal, and Vancouver experience a variety of extreme weather conditions: heavy snowfall, ice storms, and freezing temperatures are common. In some cases, temperatures can plummet to below -30 degrees Celsius, especially in cities like Montreal or Quebec. In turn, this weather creates certain challenges for architects and engineers when designing with certain materials. In this context, brick remains a popular construction material not only because of its relatively low thermal conductivity, making it a good insulator during the winter but also because of its connection to the country's architectural heritage.

While brick was once a primary load-bearing material, its role has shifted in modern architecture to being used predominantly for non-bearing walls and exterior cladding. This allows architects to experiment with brick as a texture and design feature, rather than focusing on its structural capabilities. Even though the climate does influence material choices, brick's historical significance and its ability to create intricate textures and patterns in facades make it a compelling choice for contemporary projects across Canada. Modern architects are constantly finding new ways to reinterpret this classic material, exploring various bond layouts and surface textures that add aesthetic richness while ensuring the buildings remain resilient to extreme weather conditions.

When we think of spaces that foster meditation, our minds often travel either to Japan's Zen gardens, where clean lines and carefully arranged landscaping call for stillness, or to Scandinavia's designs with neutral tones and soft fabrics. These styles evoke a sense of calm through simplicity, often seen as a characteristic of Japanese and Northern European architectural styles. Yet, stillness and meditation are not restricted to these types of settings. Latin American architectural traditions also offer powerful, though often overlooked, approaches to meditative spaces. With earthy tones of terracotta, rough adobe textures, intimate courtyards, and a strong connection to nature, these environments call for reflection through warmth and material richness, creating spaces that are calming without being understated.
