As in the original cortijo, the vertical frame is formed by load-bearing walls mostly made up of blocks of lime, earth and hemp called Cannabric. Many of the original cortijo walls were in such poor condition that it was very difficult to recover, however served to reuse the stones that were lifting and other walls.
The 30 cm Cannabric front wall improves the performance of insulation and thermal inertia of the old facades of 60 cm of stone and earth.
The floor is made of hemp and lime mortar without metal armor on a gravel fill about 15 cm and covered with a polyethylene sheet.
The unidirectional floor and vault is joist recessed in its perimetrical edge beam so that it can isolate a mortar made of same material as the front block.
To get facades working in homogeneous way were avoided thermal bridges caused by conventional landings were replaced by arcs of the same material of the wall.
On the home front, 3 meters of headroom in the interior, the same form of arch reproduced the original windows. This arch, characteristic of the area, was performed with the same Cannabric blocks to the curb made in double arch. Thus covered the window openings to south, the hole located southwest of the window and the front door.
Most flat roofs are set by type of construction in the area. Only covers part of the pigsty and chicken coop, reproduce a vault recessed in its bearings, characteristic of these auxiliary buildings.
Above wrought were performed the pitches with lime and hemp mortar. The sealing was performed with a rubber sheet. Above thermal insulation plates were placed and then two types of finishes are made on the main structure: the walkable part is covered with a protective mortar of lime and subsequently a ceramic tile; the non- passable, where solar panels are placed is covered with a protective geotextile and gravel was placed on top.
There have been two types of lime plasters: the exterior and wet areas.
To the outer two layers were applied by air lime, a first layer made by a ratio of 1:2.5 using clean sand, and a second layer in a ratio of 1:2, being a part of sand replaced by two different grain marble powder in equal proportions. This provides a textured and white finish that does not require to be painted afterwards.
For the bathroom areas, in addition to the above two layers, it has been added a third layer with a 1:1 ratio of lime and fine size marble powder. The result is a very smooth coating. To ensure better sealing, on the latter layer is applied with a brush a solution of coconut soap. The result is a smooth, slightly shiny, white and washable, waterproof but breathable wall.
The rest of the house has been plastered with plaster on a layer without the second hand and mostly unpainted, getting a rough finish. The rooms in the cottage have been painted with a paint made by hand with natural and free of toxic ingredients.
All the exterior woodworks are of high density solid wood treated with water-based varnish.
For interior woodwork has been made with a plywood ash wood doors, almost white color and a painting of craft production with natural products free of toxic and designed for a specific texture painting on white but not completely cover the grain.
- The earth: for the walls, floor slabs and cover pitches
- Lime: for plaster
- Hemp: for floors and walls
