The ÁPH80 prefab houses are made at a CNC (computer numerical control) mill factory located in Northern Spain. Designed by architect Camino Alonso—one of the owners at architectural firm Ábaton—is a compact 29.5 by 9.84 feet (9 by 3 meters) home that can get carried in a truck and deployed in 20 minutes.
The houses are made so they are easy to install in any terrain with minimum preparation, fully plumbed and wired.
Ábaton provides instructions and sketches so any crane operator can put the home in place. The home arrive fully plumbed and wired. Their prototype home is the "apartment" with kitchen/living room, bathroom (with full shower) and bedroom (bed included), but they offer other models for those looking interested in simply placing an extra bedroom in their backyard (they offer several combinations e.g. a bedroom/bathroom, 2 bedrooms, livingroom/kitchen, bedroom/living room).
The building itself is made of "CNC-milled grey cement-board panels lock together to provide not only a sleek exterior, but a ventilated facade. This layered exterior along with 10 centimeters of insulation means the home is thermally efficient—useful for off-grid purposes, but it also means that even without AC on a very hot day in Madrid, the inside of the space stayed cool."
