Ecological domes gain strength in Belém with recycled materials and automation

A couple from Belém (PA) opted for round and ecological modular constructions. The initiative became a company specializing in geodesic domes that serve accommodation and housing. The models start at R$60,000 and use recycled materials. Demand increased after COP30 in the capital of Pará last year.

Architect Tuane Costa and administrator Thales Barca founded the business. Eles developed dome-shaped structures with embedded triangles. The result combines innovative design, sustainability and practicality. The domes already attract attention for integrating technology and local resources.

Geodesic Estrutura allows quick assembly and integration into nature

The geodesic dome forms a dome made up of several triangles. Essa configuration offers stability and utilizes space efficiently. Assembly takes place in a few days. The electrical and hydraulic parts leave the factory ready.

Paredes incorporate pressed açaí waste, recycled plastics and wood from forestry management. The finish includes regionally themed tiles. Thermal and acoustic insulation maintains internal comfort even in Amazonian humidity. Modelos also has automation, such as voice command and digital lock.

• Madeira certified and reused plastics in main structures
• Isolamento thermal and acoustic on all models
• Instalação prefabricated electrical and hydraulic
• Opções automation with digital lock and voice control
• Acabamentos with local materials such as açaí waste

The rounded shape is reminiscent of a modern igloo. Janelas and openings allow views of the sky and integration with the green surroundings. Isso attracts those looking for different hosting experiences.

Demanda grew with the visibility of COP30 in the capital of Pará

The UN climate conference held at Belém in late 2025 put the domes in the spotlight. Visitantes and organizers learned about the structures as a sustainable accommodation option. Interest continued even after the event.

Tuane Costa and Thales Barca report constant search for new projects. Clientes include both lodging and private residences. The company plans to take the domes to other regions of the country. The focus remains on sustainability and the use of Amazonian resources.

Entrepreneurs highlight that the business did not emerge overnight. The project accumulates years of learning. Hoje they reap results and aim for expansion. Determination appears in the couple’s statements about putting energy into what they believe in.

Reused Materiais reduces environmental impact of construction

Cada domo prioritizes reuse. Recycled Plásticos gains a different texture on the walls. Local Resíduos, such as açaí fibers, are included in the composition. The choice reduces the use of virgin materials and values ​​the circular economy at Amazônia.

Natural insulation helps with energy efficiency. The triangular structure distributes loads evenly and resists the local climate well. Clientes report thermal comfort superior to that of conventional buildings in hot and humid regions.

Modular manufacturing allows for customization. Diferentes sizes and configurations range from accommodation suites to complete houses. The initial cost attracts those looking for more affordable alternatives to traditional construction.

Empresa aims for national expansion with model tested on Belém

The couple is considering taking the technology to other states. The experience in Belém serves as a basis for regional adaptations. Eles aims to maintain sustainable DNA, using local materials whenever possible.

Future Projetos include partnerships with hotels and tourist developments. Built-in automation facilitates operation in short-term rentals. The visual appeal and functionality make domes an option for glamping and ecological tourism.

Tuane Costa, with a background in architecture, takes care of design and technical solutions. Thales Barca manages the administrative and commercial part. The division of tasks boosted the growth of the operation.

What defines a geodesic dome and why it gains space

The construction follows the principles of Buckminster Fuller, which popularized geodesic domes. No Brasil, the Pará version adapts the concept to the local reality. Sustainable Madeira, recycled plastics and Amazonian elements create its own identity.

Vantagens include:

• Menor generation of debris during assembly
• Eficiência superior energy thanks to insulation
• Rapidez in installation compared to conventional methods
• Possibilidade disassembly and relocation
• Integração aesthetic with natural landscapes

The price starts at R$60,000 for basic models. Valores rise according to size, finish and automation. The company offers complete options for those who want to live or host visitors differently.

The business of Tuane and Thales shows how innovation and sustainability can go together at Amazônia. Round domes go from concept to commercial reality with potential for growth.
