Potato house

[1] The potato houses in Delaware were typically two-story wood-frame structures, of tall and narrow proportions, heated in winter with a coal or wood stove.

The potato houses were constructed to allow the free circulation of air among the stored crop, sometimes employing gaps between the bins and the exterior walls or at the floor level.

Multiple layers of siding, the use of red rosin paper for sealing against drafts, and sometimes the use of sawdust as insulation were other measures to safeguard the crop.

[2] In general, potato houses were two stories tall, with gable roofs aligned with the long axis.

A number of surviving potato houses has been listed on the National Register of Historic Places.
