Mountain urban planning
Introduction
The traditional architecture of Omaña is conditioned by the geographical location of the region in the Western Mountain of the province of León, Spain, the predominant economic activities in the area and a cultural heritage that, until the end of the century, has been transmitted from generation to generation with hardly any changes.
Among its most distinctive features are a rustic and functional style, the use of stone as the main construction material and the preference for buildings with a rectangular "Plan (architecture)"), with very inclined "Roof (construction)") roofs that were covered with rye straw roofs until the gradual replacement of these during the last two centuries by tiles and slabs.
The architectural heritage is threatened due to the strong depopulation of the region and the abandonment of the uses typical of the self-sufficiency economy, and there are few examples of subsidiary constructions in good condition and of homes with a traditional space distribution.
Geographic and climatic influence
The region of Omaña is, from a geographical point of view, a transition space between the plains of La Cepeda "La Cepeda (León)") to the south and the high mountain area of Luna and Babia to the north. This situation is reflected in the architecture, which, although sharing many characteristics with those of neighboring regions, acquires, due to the confluence of elements from various geographical and cultural areas, an idiosyncratic character.[1].
Omaña is located at a high altitude, with minimum altitudes that exceed the and is isolated from maritime influences by the Cantabrian Mountains, which is why winter temperatures between 0 and 2 °C and precipitation in the form of snow are common.[2] This favors the use of sloping roofs, to prevent the accumulation of snow and ice, and teito roofs, due to their properties as thermal insulation, since with a fire in the room the temperature can be maintained. Indoor temperature about 15°C in winter. The priority given to fire prevention in the last century and the consequent establishment in some municipalities of special taxes for green roofs, have led to their gradual relegation to auxiliary buildings, generally far from the main home.
The location of the stable for larger livestock directly under the houses with more than one floor, the small openings (doors, windows and vents) and the role of the kitchen "Kitchen (room)") as the main room and center of family and social life, also obey the need for maximum use of all heat sources as protection against the harshness of the climate.[3].
