You’ll Never Guess What They Used for Insulation

Another Advancement in Modern Architecture


If you haven’t noticed, modern architecture has rapidly been making significant changes in the way homes are built. Generally the changes are induced by the desire for greater efficiency, sustainability, and energy savings.  This little abode in particular is located in Ecuador and has a tree growing from within the middle of the cabin. It also has some cool wooden embellishments and a chic yet simple interior.  But none of this is what makes this little home so notable…. The reason we’re bringing this cabin to your attention is that is actually uses Pumice Stone as its insulation.  Check out these photos, then tell us your thoughts on our facebook page!


One of the problems with modernist architecture is that in many places in the world, it has supplanted traditional methods of building that over generations, have been specifically adapted to local climates, materials and knowledge. Much of this monoculture of modern architecture depends on carbon-intensive, industrial materials, creating forms that are often divorced from the unique cultures and building solutions that have developed in place, over many years. Think concrete boxes and gridded subdivisions, devouring land as far as the eye can see. Of course, modern architecture can be rehabilitated — or at least made to integrate local realities of climate, building culture and materials that are naturally available. Ecuadorian architects Luis Velasco Roldan and Ángel Hevia Antuña created this small house prototype that takes into consideration the region’s traditional building techniques, using naturally sourced and local materials and passive solar heating. The home consists of a living room, bedroom, kitchen, dining area and office. There is plenty of natural daylighting and warm materials (Ecuador laurel for exterior cladding and eucalyptus wood for framing) throughout, creating an clean and uplifting atmosphere. The bedroom is lovely, featuring a glazed corner and skylight that doubles as a reading nook and solarium. The home’s innovative use of this material allows it to maintain interior temperatures of 20 to 21°C (68 to 70°F) all year round, even when it got as cold as 12°C (53°F) outside. Pumice was used once more on the insulating green roof above, as a drainage layer.
