Integrated architecture: construction practices in relation

INTEGRATED ARCHITECTURE

Building with earth, plant fibers and wood has been part of everyday life in many communities for generations. What is now referred to as “natural building” or “vernacular architecture” is not about aesthetics or alternative choice. These are practices rooted in ways of living that respect the cycle of materials, the rhythm of the seasons and the resources available in each place.

These techniques haven’t been left in the past. They are still passed on through collective work, community building efforts, informal exchanges and ongoing adaptations. The thermal efficiency of adobe, the durability of rammed earth, and the lightness of thatched roofs continue to offer strong references for those looking for climate-appropriate and context-sensitive construction.

The renewed interest in these methods opens space to revisit knowledge built by peoples who learned to build by observing and responding to their surroundings. This review also brings in new tools and perspectives, such as natural additives to increase stability, and simple sensors to monitor humidity and thermal performance — all integrated with existing construction know-how.

ADOBE, RAMMED EARTH AND THATCHED ROOFS

Adobe: a millennia-old technique that uses sun-dried bricks made of clay, sand, water, and sometimes straw or manure for binding. Once molded and dried under the sun, the bricks become strong enough to build houses, temples, and even fortresses. Adobe appears in many regions of the world, from ancient Egypt to the Americas. A well-known example is the structures of Pueblo Bonito, at Chaco Canyon National Park in the U.S. Adobe walls regulate indoor temperatures well and ensure thermal comfort. Many of these structures have stood for centuries, proving the material’s resilience.

Rammed earth: This technique involves compacting wet soil inside wooden or metal molds. Layer by layer, the soil is compressed until it forms solid walls with excellent thermal and acoustic insulation. Historical records show this method in ancient China, medieval Europe, and in Brazil. The rammed earth walls of Piracaia, a town in the interior of São Paulo state, are an example of how such structures can remain stable across generations.

Thatched roofs: made with grass or cereal straw fixed to wooden frames. This material provides protection from rain and sun, while keeping indoor temperatures stable. It depends on renewable, locally available resources, which helps reduce environmental impact. Thatched roofs are common in rural areas across Africa, Latin America and parts of Asia. Besides offering effective coverage, the technique visually blends into the landscape and keeps alive a traditional building practice.

ANIMAL
ARCHITECTURE
AND BIOMIMICRY

SOLUTIONS THAT OBSERVE THE ENVIRONMENT

Animal architecture is the field dedicated to structures built by different species to meet vital needs. These are constructions made for shelter, reproduction, protection from predators or food storage. Each design responds directly to the environment, uses available materials, regulates internal temperature, prevents moisture and allows air flow. Termite mounds, hives, webs and nests are examples of structures that not only solve functional challenges but also contribute to environmental processes like soil aeration and nutrient cycling.

Biomimicry studies these strategies and translates them into human design applications. Research in this field has already led to real-world results:

Natural cooling towers that keep indoor temperature stable while reducing energy consumption.

Buildings with passive cooling, based on natural ventilation systems.

Railway stations and airport roofs designed to improve airflow and natural lighting.

Bridges and structural supports modeled after high-strength, low-weight natural forms.

Solar panels inspired by patterns that enhance light capture and energy efficiency.
