For the fourth time, we are giving our readers the responsibility of recognizing and awarding the projects that have made the greatest impact on the profession through the 2020 ArchDaily Brasil Building of the Year Award. By voting, you become part of an impartial network of jurors recognizing the most relevant projects of the past year.

Over the next three weeks, the collective intelligence of our readers will filter through hundreds of projects from Portuguese-speaking countries—Brazil, Portugal, Mozambique, Angola, Guinea-Bissau, East Timor, Equatorial Guinea, Macau, Cape Verde, and São Tomé and Príncipe—published in 2019, selecting the best built works in the Portuguese-speaking world.

From a pool of hundreds of projects published in 2019, readers will choose their favorites, with the 15 most voted advancing to the second stage of voting.

Brazilian architect Marcelo Ferraz, founder of the firm Brasil Arquitetura, is the first guest on Studio Casa, an interview series produced by Casa da Arquitectura - Portuguese Center for Architecture.

Sesc São Paulo has made a series of catalogs, educational materials, and booklets produced for the institution's exhibitions available for free on its website. Fittingly, several of these themes intersect with thinking on architecture and the city.

Many factors influence people's well-being, but few have power as great as the quality of sleep. Adults spend, on average, a third of their day (and their life) sleeping. In the case of young children, this proportion is even higher. According to a study published by the WHO in 2019, babies (4 to 11 months) should sleep between 12 and 16 hours/day; and children up to 4 years old should sleep between 10 and 13 hours/day.

Quality sleep acts directly on the child's brain development, especially during his first and second childhood (from birth to 12 years old). During the rest period, the body releases the hormones necessary for growth and learning, and this is directly related to physical, motor, emotional, and cognitive development. It is also known that the environment where one sleeps interferes with the quality of that sleep, and some important aspects must be considered when designing sleeping spaces for children and babies.

The relationship between architecture and structure has been widely discussed and is repeatedly revisited by architects with every new project. Much like plumbing and electrical systems, the structural system is one of the essential disciplines that make up a building. Yet, it is one of the most impactful on the architectural outcome, directly shaping the spatial experience and the chosen materiality. Mastering structural design and understanding how to best integrate it into the architectural project grants architects greater autonomy and expands the possibilities of design solutions. 

Selecting a structural system and deciding how to incorporate it into the architectural design is a pivotal decision in any project. On one hand, architects can choose to absorb structural elements, camouflaging them within the building envelope to make them imperceptible. On the other, the structural system can be brought to the forefront, turning into a defining feature of the design—whether through its structural logic, its materiality, or by being elevated to a nearly sculptural element.

This article explores a term widely used to describe self-organized collective labor, but which also carries a meaning of anti-hegemonic struggle when used as a synonym for self-managed projects. The practice of mutirões prompts a reflection on the importance of collective work and grassroots struggle, and how architectural practice and civil construction relate to these themes.

Marcelo Ferraz, founding partner—alongside Francisco Fanucci—of Brasil Arquitetura, an office that has garnered numerous national and international awards in recognition of projects that are deeply sensitive to their site, yet essentially contemporary, is this week's guest on Arquicast.

Beyond viewing the home as mere shelter and protection, there is now a much greater complexity of functions integrated into the elementary programs of dwelling. We no longer think only of spaces for sleeping, cooking, and bathing, but rather of a series of new programs that demand new spaces and configurations. Among these, leisure emerges as an activity integrated into living, in the form of backyards, swimming pools, and TV rooms.

Everything built through human physical and intellectual labor carries meaning. It is within physical matter that we find the remains of ancient civilizations, and through these records, we understand their characteristics, the technologies involved, and their social organization. Cities and major urban centers hold layers upon layers of events recorded in their streets, buildings, plazas, and parks. Often, depending on the development of the place, this evidence is gradually erased, disregarded, and altered.

Houses are the most intimate structures we as architects can design. It is no coincidence that intimacy, security, and privacy are recurring concepts in residential architecture. Yet, like all architecture, houses are inevitably embedded in a context—an environment with which they must engage. There are many ways to achieve this, particularly within highly dense urban fabrics, as is the case in many Brazilian cities.
