As the world gathers in Belém for COP30, Brazilian developers are turning to local eucalyptus, including reforested timbers, to build low-rise and mid-rise housing.
“In recent years, construction using sawn timber from reforestation has regained popularity in Brazil, especially in compact projects of 30 to 40 square meters,” said one Paraná‑based builder. “The combination of competitive price, speed of assembly, sustainability, and thermal performance has made this system a real alternative for affordable housing.”
The revival, according to Click Petróleo e Gás, a Brazilian industry publication, has been fueled by the expansion of pine and eucalyptus plantations in the Southern and Southeastern Regions. Autoclave treatment, kiln‑drying, and standardised structural sections have transformed what was once dismissed as a “simple wooden house” into a modern, durable system.
Several companies in Paraná, Santa Catarina, Rio Grande do Sul, and Minas Gerais now promise delivery in under three weeks, creating what analysts describe as a new ecosystem of lightweight, industrialised construction that could help Brazil close its 5 million housing gap.
It’s cheaper, faster, and better for the environment
Builders estimate that a 40-square-meter timber home can be built for between R$70,000 and R$150,000 – or US $15,000 to US $30,000, depending on the region and finish. A basic package, assembled in less than 10 days, includes wall panels, beams, simple doors and windows, and a lightweight roof. More popular intermediate versions incorporate insulation, waterproofing, and improved seals, while premium models utilise kiln-dried timber, acoustic sealing, and minimalist finishes. “This is the most sought‑after standard in Brazil,” said a contractor in Santa Catarina, “because it offers evident thermal comfort.”
By comparison, a masonry house of the exact size costs between R$130,000 and R$190,000 – or US $25,000 to US $35,000 – and takes two to four months to complete. Timber homes can be delivered in five to twenty days, cutting indirect costs such as rent during construction and labour overhead. “The wood arrives cut, treated, and dimensioned — practically a structured kit,” explained a supplier in Minas Gerais. “That reduces time, labour, and waste.”
Durability has also improved. With autoclave‑treated wood and routine maintenance, lifespans reach 40 to 60 years. Builders say that common mistakes of the past — such as untreated wood, poor ventilation, and direct ground contact — have been largely overcome. “Today, with engineered wood, the problem has been solved in reputable companies,” said one industry executive.
Aesthetics are part of the appeal. Exposed wood, clean lines, and large windows have become a social‑media trend, fueling demand for chalets, rental studios, and farm expansions. Buyers are drawn not only to the look but also to the performance. Timber houses stay cooler in summer and warmer in winter, a natural advantage in Brazil’s varied climate.
The surge reflects broader forces, including rising cement and brick prices, a shortage of skilled masonry labour, and growing interest in sustainability and minimalist architecture. The expansion of Airbnb and short‑term rentals has also created demand for small, quickly built units.
Analysts expect rapid growth in timber construction, with greater industrialisation of kits, hybrid wood-steel systems, and a broader use of mass timber projects, such as cross-laminated timber. For now, the numbers speak for themselves. Faster, cheaper, and greener, timber houses offer a solution for Brazil’s housing crisis — one 40 square metre house at a time.
