Sustainable dome-shaped structures advance in Brazil with a proposal for rapid construction, use of recycled materials, and technological solutions that combine comfort, energy efficiency, and integration with nature in residential and tourist projects.
Round, modular houses made with recycled materials are starting to gain ground in Belém, Pará, with models of geodesic domes sold from R$ 60,000, bringing together construction solutions that combine efficiency, sustainability, and adaptation to the local climate.
In addition to their unusual shape, these structures integrate rapid assembly, thermal and acoustic insulation, automation, and ecological finishes, characteristics that increase interest for both housing and projects aimed at experience tourism in natural environments.
Leading the initiative is Amazônia Domos, a company created by architect Tuane Costa and administrator Thales Barca, who are directing the business towards sustainable constructions for lodging, compact homes, and ventures aligned with environmental tourism.

Architects and Engineers point to a 2 to 3 mm coating as a possible substitute for porcelain and traditional ceramic tiles: microcement covers walls, floors, and countertops without demolition, without grout lines, and with less debris in modern renovations.
Driven by the visibility of COP30, held in Belém between November 10 and 21, 2025, demand for the domes has grown consistently, reflecting increased interest in construction solutions with lower environmental impact in the capital of Pará.
What is a geodesic dome and how does the structure work?
Characterized by its dome shape, the geodesic dome is formed by triangular pieces that fit together precisely, creating a resistant structure that better distributes weight and reduces the need for pillars or internal divisions.
Although it resembles an igloo in form, the model incorporates contemporary materials and technological resources, while the combination of wood, recycled plastic, and other repurposed inputs contributes to reducing waste and making the construction process more efficient.
Directly from the factory, models can come with pre-installed electrical and hydraulic systems, which reduces construction steps and speeds up final delivery, in addition to including versions with digital locks, voice command, and automation systems.
Adding to these features are glass walls facing the exterior, an element that enhances integration with the landscape and promotes the entry of natural light into the interior of the structure.
Recycled materials and Amazonian regional identity
In the composition of the domes, the company prioritizes natural, recyclable, and repurposed materials, adopting solutions that align with sustainable practices and the use of resources available in the Amazon region.
Examples presented include recycled plastics with a texture similar to the lunar surface and pressed açaí residues, applied to the walls as an alternative finish with local identity.
Regional elements also appear in the internal design, as bathrooms can feature tiles with patterns produced by local artisans, while furniture uses certified forest management wood.
Beyond the aesthetic aspect, these materials play a relevant technical role, as thermal insulation reduces heat exchange with the external environment, while acoustic insulation contributes to greater comfort inside.
Modular construction reduces construction time and expands applications
As a central part of the model, modular construction allows stages to be anticipated off-site, reducing assembly time compared to traditional methods, depending on terrain conditions and the contracted project.
Thus, the use of domes expands to different purposes, serving everything from tourist ventures and guesthouses to rural areas and alternative lodging projects, always with a focus on integration with the natural environment.
Inside, the space can be configured with a bed, bathroom, planned lighting, and automated systems, while the glass wall stands out for allowing sky observation and reinforcing the connection with the surroundings.
COP30 drives demand for sustainable solutions
With the holding of COP30 in Belém, companies linked to sustainability gained visibility, a scenario that contributed to domes being considered a viable alternative for compact and quickly deployable accommodation.
According to Tuane Costa and Thales Barca, the project’s growth is associated with a continuous development process, the result of years of planning and execution until reaching the current stage of expansion.
“When you are determined within a project, the sky is the limit.”
“It’s a process that started a long time ago, and we are just beginning to reap the rewards, but we will go very far.”
Company bets on market expansion and consolidation
Currently, Amazônia Domos operates in Belém and focuses its communication on digital channels, including the email contato@amazoniadomos.com.br and the @amazoniadomoseciaof profile on Instagram.
Headquartered in the capital of Pará, the company presents its projects as solutions developed in the Amazon, combining modular architecture, repurposed materials, and finishes aimed at sustainable tourism, in a model that seeks to gain ground in other regions of the country.
