Tiny House Shadow: a small size home with big environmental benefits

Architect and Aalto University professor Matti Kuittinen has been leading the Tiny Homes project, which has investigated the emissions of different types of housing and what it would be like to live in the lowest possible emissions.

The project has now reached the pilot phase, with construction of the Tiny House Shadow starting this spring in collaboration with Aulis Lundell Oy. The purpose of the construction of the small detached house is to explore the material efficiency of detached housing and the potential for reducing the carbon footprint. 

"We are looking at how we can design and build efficiently, and we will make carbon footprint calculations for every step of the way. If necessary, the experiment can be repeated," says Kuittinen.

He stresses that humanity has a limited carbon budget, and construction must adopt ways to stay within it. 

His team has compared whether mini houses are more environmentally friendly than large houses, whether measured in terms of emissions per square metre or per occupant. 

"The emissions and material consumption of mini-houses are superior on a per-user basis," Kuittinen points out. 
 

Piloting recycled materials everywhere

At Tiny House Shadow, the focus is on making the most of the circular economy. Kuittinen admits that current building regulations do not necessarily support this type of construction, which uses a lot of recycled material.

The aim is to build the house from more than 50% reused and recycled materials, with the rest of the materials coming from the lowest possible carbon sources.

"For example, we use old windows and doors, recycled steel, wood and car tyres, industrial by-products and plastic composites containing recycled materials," says Kuittinen. 

Recycled materials are a key element in Talo Varjo.

The interiors will be multifunctional and adaptable. The interior of the house is minimalist and functional.

"For example, the kitchen has no cupboards, but open shelves," Kuittinen says. "We want to reduce unnecessary clutter."

When the Shadow house is completed this spring, he plans to move in herself for the duration of the project.

"I've tried capsule hotels when I was abroad," he laughs. 

The Tiny Homes project shows that while homes may be small, their environmental benefits can be big if the right solutions are put in place.
