This is a post-and-beam infill straw bale house built in 2016 in Italy.

Designed by Jimmi Pianezzola Architetto, the SCL Straw-Bale House was built with beams and straw bales, conveying the area’s traditional architecture.

The walls are made of straw bales rendered with lime for an appealing look.

The ground floor – a crucial part of the building is compact and built on what the design team called the “golden area” to provide sufficient support. Moreover, this floor is covered in recycled crushed foam glass on a geotextile membrane for insulation.

The structure features a stone garden patio that hosts a nonstop natural light show.

To ensure stability, the building’s foundation was made with reinforced concrete and has a roof made of sheet panels.

Like any other post-and-beam infill house, the wooden structures are filled with straw bales for enhanced insulation. Therefore, the building conserves as much heat as possible to reduce heating and cooling energy.

The interior features an open plan with large windows that provide great views of the surrounding area.

5. Wood and Straw Housing-France

A small housing development made from wood and straw bales. The houses have staggered frontages, with every other house set back from the rest, which creates a small private area that is not overlooked. There is parking out front and footpaths linking all the houses together. The houses are different colors, with some being predominantly black, others natural wood color and others white. There is a small sports facility behind the houses in parkland.

This house was built with prefabricated cassettes of straw bales in 2019 by NZI Architects.

The housing project features three blocks; A, B, and C. These blocks have 4, 5, and 4 houses, respectively. A pedestrian footpath connects all the houses.

According to NZI Architects, using prefabricated cassettes was an excellent way to reduce time spent on the site, and the project’s cost and to maximize the use of sustainable construction materials.

The first phase of the construction entailed erecting the structural timber frame to support the cassettes. Afterward, the prefabricated cassettes were filled between the timber beams, creating the wall.

The houses have a pitched roof profile with a lightweight steel structure and windproof coverings.

In terms of energy efficiency, the house is well insulated due to its straw bale walls and wooden frame for maximum thermal mass.

The interior wall combines various finishes, from white stained to natural charred wood; the walls make for an attractive visual display that adds character to the building.

A generous amount of natural light penetrates the space, giving it a warm atmosphere.

6. K-House-Ontario, Canada

K-House in Ontario is an excellent depiction of state-of-the-art straw bale buildings in Canada. Designed by architect Nicolas Koff, the building features 40-cm thick prefabricated straw bale walls.

The wall is thick enough to act as an excellent insulator for the building. It plays a significant role in regulating indoor temperature without relying on an HVAC system.

The design encompasses fireplaces for heating and strategically-positioned windows for cooling when it’s hot.

Many think having fire and straw in the same place poses a fire risk. However, this is not true, and this building was designed to be highly fire-resistant.

The architect said the straw bales were tightly compressed to eliminate air spaces. Without air spaces in the straw bales, fire won’t be able to spread.

The structure has a metal roof that supports solar panels for heating and lighting. This offsets the home’s energy use, making it much more sustainable.

7. Inspire Bradford Business Park – Bradford

Kristen was an eco-conscious woman who always wanted to be close to nature. After visiting a cob building site, Kristen fell in love with the designs and, as a result, started planning her own straw bale and cob home.

She wanted a home that was made from 100% natural materials.

After a lengthy consultation, she realized her dream in 2000 by building her cob and straw bale house. Luckily, she had many offers of help with this ambitious project, spearheaded by Ianto Evans from the Cob Cottage Company.

The home’s foundation is a stone and rubble trench. While the exterior walls are made of straw bales, the internal walls are made of cob mortar with lime.

They included a thatched roof and a “greenhouse” with large windows which catches the sun’s rays to keep the house warm on sunny days.

Finally, they erected a central mass heater to keep the house warm on colder, overcast days.

This is the first straw bale hotel in Europe. The hotel was built with a focus on sustainability and the preservation of nature.

The owners, Lisa and Louis, used 55 tons of straw bales and 95 tons of wood. Their main aim was to achieve the highest energy efficiency standards and make the hotel self-sufficient in terms of energy.

By combining straw bales and wood, they realized that the Maya Boutique Hotel’s energy efficiency exceeded the requirement for passive house standards.

The straw bales provided sufficient insulation to conserve energy and retain it to keep the entire living space warm. For instance, by conserving heat from its occupants, cooking activities, and sunlight, they could keep the hotel warm without additional heating. 

Moreover, after the hotel’s construction, they installed a solar thermal system to provide heat and power. Instead of dissipating the heat generated within the structure, it’s used to heat water for showers, dishwashers, and washing machines.

As one of the most amazing straw bale houses in the world, the Maya Boutique Hotel is an excellent example of how straw bale construction helps conserve energy, lowering energy bills by reducing heating and cooling needs.
