Five Green Buildings That Prove Sustainable Architecture Can Be Beautiful

Construction accounts for more than a third of global emissions, and the five buildings below show how the industry can cut that share without producing something ugly. The projects — in Brazil, Indonesia, Sweden, Australia and the UK — all put low-carbon materials and local sourcing first. David Mikhail, co-founder of the UK sustainable-design practice Mikhail Riches, walked through each one and explained what makes the approach work.

Children's Village, Tocantins, Brazil

In 2017, architects gave the Canuanã boarding school in central Brazil two new dormitory "villages", one for girls and one for boys, for its 540 pupils, who come from remote farming communities across the region. The buildings use locally sourced timber and earth bricks. A vast canopy shades the complex, and perforated brick walls let air pass through, so the bedrooms stay comfortable without air conditioning even at 45C.

Mikhail is blunt about it: "It is absolutely fantastic. So beautiful. It does a lot with little resource, which is the essence of a sustainable approach." He adds: "I love the economy of it, and the huge sense of place they managed to evoke through such elegant and limited means."

The architects said their biggest challenge was convincing pupils and teachers that earth, brick and timber could feel modern rather than old-fashioned. They solved it by running 10 days of workshops with students to learn what they wanted from the design.

The Arc, Bali, Indonesia

The Green School in Bali has been built almost entirely in bamboo since it opened in 2008. Its gymnasium, the Arc, was completed in 2021. Bamboo arches inspired by a mammal's ribcage span a 760 sq metre sports court without a single column interrupting the floor. Breezes flow in at the base while warm air escapes through vents at the top, so the building ventilates itself.

The material logic is simple: large bamboo varieties reach building strength in just three to six years. "It is so fast-growing and sequesters a lot of carbon dioxide very quickly, so using it for building is a bit of a no-brainer if you can make it work," says Mikhail. "And not only have they made it work, they've done it absolutely beautifully."

Sara Kulturhus, Skellefteå, Sweden

Skellefteå, a small city just south of the Arctic Circle, sits amid 480,000 hectares (1.2m acres) of forest and already had wooden schools, a wooden road bridge and a wooden multistorey car park. In 2021 it added Sara Kulturhus, a 20-storey cultural centre and hotel that ranks among the tallest timber buildings in the world. It contains two theatres, a museum, an art gallery, the city library and a hotel.

The structure uses glulam (layers of timber glued together) and cross-laminated timber, a kind of super-sized plywood. Hotel rooms arrived as prefabricated wooden pods and were stacked into place. Building in wood saved a year compared with steel and concrete; the trees were harvested within 40 miles of the site, and replacements have been planted.

"It promotes a love affair with wood and timber, and the localism of that in an area like Sweden is fabulous," Mikhail says. He notes that cross-laminated timber doesn't need elderly specimen trees — the panels can come from relatively fast-grown, sustainably farmed stock.

The Forest, Hobart, Australia

For the redevelopment of its main campus in central Hobart, the University of Tasmania chose to adapt rather than demolish. Two early 20th-century brick warehouses and a heritage-listed glass dome were stitched into a single campus of classrooms and study spaces, which opened in February 2026.

At its heart sits the 1997 glass dome, now filled with about 3,200 native plants, including several fern species, with an integrated watering, misting and fogging system that recreates rainforest-like conditions.

"You could argue the most sustainable building is actually no building, and the second most sustainable building is a refurbished old building," says Mikhail. "That's what this is: they're taking existing structures and breathing new life into them, reimagining what they could be."

Rammed Earth House, Cranborne Chase, UK

On a former brickworks site in Wiltshire, this house is built from the ground beneath it. Rammed earth — soil compacted layer by layer into thick walls, a technique used since the Neolithic period — was made here from clay-rich soil mixed with rubble from demolished outbuildings and local limestone.

The earth is "unstabilised", meaning no cement was added, which makes this one of only a few UK buildings made that way. In principle, the walls could simply go back into the ground if the house were ever demolished. Rammed earth's thermal mass also evens out indoor temperature and moisture — a property the architects say will matter more as the climate warms.

"As a piece of architecture, I think it's phenomenal," says Mikhail. "It's an architect's dream, and I'm slightly envious of it, I'll be honest." He calls it "like a beautiful piece of jewellery, and it riffs on lots of really lovely sustainable ideas."

What does this change for architecture?

The five projects share a pattern: local material, low processing, and reuse where possible. Mikhail's summary of the Hobart project — that the second most sustainable building is a refurbished old one — is the practical takeaway for anyone planning new construction in a sector responsible for over a third of global emissions.
