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.

Metallic elements have been used in architecture and civil construction for hundreds of years, either as decorative elements, coverings or even to reinforce masonry structures. However, it is only in the second half of the eighteenth century that the first bridges emerge whose structure was entirely made of cast iron. A century later, iron was replaced by a more resistant and malleable alloy, still used today in architecture: steel.

Denser than concrete, the strength of steel subverts its weight and provides greater stiffness with less material - allowing for lighter and thinner structures than those made from other materials, such as wood or concrete. It is by no means the most used material in residential architecture, however, its use has made it possible to construct some interesting - and beautiful - examples of contemporary houses:
