It should be noted the difference in the complex of the three villages that make up this town.
LOZOYUELA maintains a more urban-rural, with buildings that are clustered around Avenida de Madrid, main street and its many squares (Plaza de San Quintin, Plaza de la Constitución, Plaza de Ramón y Cajal). Buildings which are rectangular plant, developed on two levels, often with cameras, or envelopes, with the exceptional presence of a third floor. All households respond to traditional construction systems and programs based on the systematic use of load-bearing walls of masonry and Arabic tile roofing with eaves canecillos flown on wood or stone moldings convex.

The wall panels, which become more development in the imprint of more urban housing, are of masonry granite gear towards the regular, if not overturned and lime. The blocks, which reach pads, are used selectively in the formation of recerca sockets and spans, as well as the reinforcement of the corners, giving a sober picture of the housing elements of formal expressiveness.

The examination of each of the components that form the base of buildings leads us to distinguish two decorative architectural trends represented in LOZOYUELA and Las Navas de Buitrago two groups of buildings. The first one is composed of the housing containing proposals for a more popular and closer to the rural budgets. The facades, small design and development space, and generally whitewashed enfoscadas present elementary recerca vain, being the notable absence of moldings, or any other remedy joint.

The second trend is represented by the group formed by the residential buildings that collect more elements of urban architecture, have a greater degree of processing. The facades, acquire greater emphasis and importance to them and makes its appearance imposta lines to separate and distinguish plants. Besides the holes, sometimes abocinados is recerca with large blocks, sometimes rough pads.

Las Navas de Buitrago Sieteiglesias and keep intact the very structure of rural ranchers in the Sierra. In all three villages, including LOZOYUELA, there are numerous examples of rural homes that meet a certain homogeneity typological, constructive showing sufficient similarities as to study together. The buildings included in this typology, are scattered throughout different parts of the old helmets population integrated into the urban fabric, still keep alive the character of agriculture, especially in Las Navas and Sieteiglesias.

These buildings are usually rectangular, developed in one or two heights that are exceptionally immune, although the most common is that they fall between medianerías. Constructively, running cargo with thick masonry walls that hold large granite tile skirts of curve covering the internal structures of wood. The primitive types are characterized by a cottage house, which is evidenced by a total absence of the principles of symmetry and proportion. Simple volumes, strong walls, small openings and low, wide covered. etc. are some of the constants that make up the vernacular architecture tightly designed. Rural housing is scheduled to meet as many functions in the smallest space possible. This will generate useful domestic spaces, where the home and kitchen with oven (noticeable as a small outdoor apse) constitute the core around which the bedrooms are available.

Too often the nature of ancillary agricultural buildings (houses, cottages, stables, etc.). Paraments be attached to the outside. This kind of auxiliary rectangular, usually developed in a single height, are composed of a single space primarily to shelter animals. The connection to the outside is by means of large doors, with the exceptional appearance of another kind of vain, if shown, are functional. The masonry wall is not reached, similar to domestic buildings. The devoted and birds are the two types of ancillary buildings of interest and are independent units of the domestic area.

As for the mixed residential agricultural sets are widely represented in the population centers of Las Navas-LOZOYUELA-Sieteiglesias, with its stronger presence in the last two. These are sets of buildings that are grouped into multiple medianerías, to form complete blocks at times, now in process of abandonment and degradation. Load-bearing walls are masonry without reservation. The problems posed by specific constructive corners, jambs and lintels are solved by means of large pieces of rough-hewn granite. Façades is unique in the appearance of success, which buys small solely to the basic functions of lighting and ventilation. The tile-covered curve, which are supported internally by wood beams, joists, presented a comprehensive development of the tail.

Based on the uses and functions, each of the spaces that make up the sets receive a special name:

• The house, itself.
• Courts or cottages, rooms for hostel pigs.
• The aimed to keep cars or sheds and tools, as well as for albegue animals.
• The birds used to store crops and the cattle stall.

Inside, the house is divided only in the kitchen (where the furnace is located) and the bedrooms. The remaining units contain only a space for the accommodation of livestock. Regarding the most important architectural landmarks art, there are:

• San Nicolás de Bari
• San Pedro Apóstol
• Iglesia de la Santa Cruz
• Ermita de la Virgen de la Soledad
• Puente Romano
