Underground cold frame at Paliomylos.

We decided to build an underground cold frame as nursery for the springtime garden. During the last weeks of winter is necessary to start planting seeds that will later be transplanted into the garden. Temperatures here can lead to freezing during the night. The cold frame must have enough insulation to maintain a higher indoor temperature and prevent the plants from die.

The idea evolved from a design that includes a trench inside, using the terrain as support. The place where is doing to be done faces the south, and has the old channel wall just behind. The foundations of the wall are stones, in which we excavate. Therefore, the thermal mass of the wall heated by day, should provide certain temperature into the cold frame. To isolate more at night, we will place a door with double glazing.
