Gallery: Casa Garoza: Spanish Prefab Prototype is Designed to Grow Over...

Final floorplan for entire house with both sides installed.

In 2010 Herreros Arquitectos completed the industrialized prototype for their growing house, which focuses on resource efficiency, recycling and sustainability. During the first phase of construction 4 sections are transported via truck, then hoisted into place on top of a foundation of piers. After all the modules are in place the exterior skin is sealed up. Each module is fabricated in a factory and includes all the interior finishes, built-in furniture and part of the exterior.

The modules are the maximum size for shipment via roads in Spain (3m wide, 2.50m high, and up to 12m long), which is much smaller than what we can transport in the US. Limitations in transport sizes, whether in the US or Europe, have a huge effect on the design of prefab homes.

When the family decides it is time to expand, four more modules will be manufactured and shipped to the site, where they can easily hook into the existing home. Existing exterior doors will become interior doors to the other side of the house, and the home will include multiple bedrooms and bathrooms. Future additions are challenging and often costly in most custom and prefab homes, but if the addition is planned from the beginning, the overall design is more efficient and cohesive. The cost for the basic 75 sq meter home is 200,000€, but this amount decreases as the size of the home increases.
