On September 21, the world celebrates Arbor Day, a date aimed at raising awareness about environmental conservation. During childhood, we establish relationships with nature that become deeply rooted in our imagination, eventually evolving to influence architectural design. We have selected 22 projects of various uses that draw inspiration from our relationship with nature and this shared imagination.
Every year, our curatorial team presents a retrospective of house projects that stood out over the period. This collection, a small selection of the more than two thousand projects published on ArchDaily Brasil this year alone, comprises a series of residences with specific design solutions that address, each in their own way, factors such as materials, construction techniques, structural systems, building processes, and programs.
At a time of ecological collapse and rising food insecurity, architecture is increasingly called upon to engage not only with landscapes but with the systems that sustain and regenerate them. Among these systems, agriculture occupies a paradoxical role, as both a leading contributor to environmental degradation and a potential agent of ecological recovery. Industrial farming has depleted soils, fragmented habitats, and driven climate change through monocultures, fossil-fuel dependency, and territorial standardization. In response, agroecology has emerged as a counter-practice rooted in biodiversity, local knowledge, and the cyclical rhythms of nature. It reframes farming not as extraction, but as regeneration of ecosystems, communities, and the soil itself.
This reframing opens space for architecture to contribute meaningfully. To align with agroecology is not only to support food production, but to engage with the broader cultural, spatial, and ecological conditions that sustain it. It implies designing with seasonal variation, supporting shared use, and building in ways that respect both the land and those who work it. Architecture becomes more than enclosure — it becomes a mediator of cultivation, reciprocity, and coexistence.
The concept of permaculture refers to a design system capable of creating sustainable human environments based on an ethic and a series of ecological, environmental, and resilience design principles. In contact with plants, animals, buildings, and infrastructures such as water, energy, and/or communications, permaculture analyzes the possible relationships between these elements based on their position in the landscape. Its 12 design principles can be applied in multiple architecture projects of varying scales and programs, contributing, for example, to the dissemination of new ways to reduce energy consumption in homes, save water through rainwater harvesting or the recycling of greywater for sanitary systems, gardens, and more, and participate in food production, among other matters.
Every year, ArchDaily's curatorial team publishes thousands of new architectural projects. From this experience, we know that no one builds alone and that these projects would not have been possible without the collaboration of many other professionals that are as much involved as the architects and designers themselves.
More than 5000 new projects published throughout 2021 make ArchDaily the largest online architecture library in the world. ArchDaily Curatorial Team researches, contacts offices, prepares, and delivers the built projects in the world on a daily basis, with the objective of providing inspiration, knowledge, and tools to our users who take part in the creation of better built environments.
Residential architecture is one of the most popular categories among our readers. In 2021 we published more than 3,800 projects, featuring houses from different regions of the world and offering a variety of solutions, materials, contexts, environments, scales, and typologies. Providing a broad source of inspiration for those seeking references for their own residential project.
