The type known as mountain house, is a form of traditional construction typical of La Montaña and extended throughout the autonomous community of Cantabria, as well

as in eastern Asturias and northern Castilla y León, in northern Spain.[1]​.

It had its origin in the centuries , and, acquiring its greatest diffusion at the end of the century and first third of the . During this last period, with the architect Leonardo Rucabado, this type of regionalist architecture became popular in Cantabria, determined by the historicist evocation of the mountain architecture of past centuries. This current would later continue with his disciple Javier González de Riancho.

This type of traditional rural house is the most characteristic of Cantabria. The south façade stands out, open to the sun and light, while the others offer thick walls of rough masonry. The corners are usually made of ashlars with fencing in all the openings. The entrance is through a gate with one or two arches "Arco (architecture)"), with sufficient depth to shelter the cart, implements and firewood, giving way to the stragal, from which the kitchen is distributed (although sometimes this is on the second floor), stable, cellar, pantry and staircase to the upper floor. In some areas, there are "Skate (architecture)" skates to access the upper floor directly from the outside.

On this floor are the bedrooms, of which the two main ones, in addition to the central room, open onto the utility room. To this we must add the tascón or haystack. The interior partitions are originally usually made of wood, although in recent times they have been replaced by brick.

The sunroom is the most typical element of this construction. It is a continuous balcony with a wooden railing protected from the winds and rain by the side walls that fly at the same time, like stone projections of the fabric of the façade, to support a very protruding "Cover (construction)" eave, being finished off at the bottom with a corbel-like molding that generally takes the shape of a heel.

In their upper part, these walls are usually finished off with rough moldings but with classic profiles, serving as support for the edge beams as a support for the "Can (architecture)" canes that make up the "Cover (construction)" eaves. The wood, which involves carving and lathe work, is usually painted dark brown.
