The construction is carried out by Paraguayan companies and workers under the supervision of a German engineer. The buildings’ warranty period is 5 years. Bricks, tiles and construction wood are all-natural materials. We guarantee that all other materials used are ecologically harmless.
The lots have polyethylene potable water pipes (“Virgin” quality) and power lines (230 VAC). Internet is installed by private providers. All roads, paths and sidewalks have a solid base and are covered with a layer of gravel.
DN 100 PVC pipes are used for house sewers. The lines run from the building through a manhole and drain into a septic tank. The pre-treated waste water is pumped through a feeder, by free flow, or from a pump to a biological water treatment plant. The size of the facility will be proportional to the number of dwelling units; the minimum size is 8 sq. m. The treated waste water is discharged through a catch basin to a filtration channel.
Rain water from roofs is collected in tanks or drainage sumps.
The foundation of the house is made with a crushed stone base and is 0.10 m above ground level. The depth of the foundation is 0.70 m; or less according to the depth of bedrock, the width of the base is at least 0.40 m. A sustainable compact material is inserted between the two bases. A polyethylene membrane is placed over the gravel sub floor as a moisture barrier, which is then covered by a layer of concrete to which the flooring material of choice is applied.
The copper grounding electrode is inserted into the soil beneath the floor structure.
The surface of the foundation is well built and sealed with bitumen sheets. Another moisture barrier is applied to the lower masonry with bitumen sheets. The outer wall consists of 25 cm wide masonry building blocks and a concrete beam with braided reinforcements. Masonry can be finished with natural stone tile (approx. 7 cm) or double plaster coated (approx. 4 cm).
The interior walls are solid brick or adobe and are 12 cm or 24 cm thick, depending on static requirements. The interior walls may be fascia brick or covered with clay or lime plaster at least 2 cm thick. Optionally, the interior walls can be made of natural stone or covered with natural stone tile.
The columns are made of bricks, with a concrete core if necessary. They can be clad with natural stone or clinker bricks.
Wooden structures such as roof lattice work are made from local hardwood such as Kurupay or Yvyra Pyta. If desired, the beams may be left visible on the inside. Due to the improved insulation, coated support plates are recommended. A double-layered framework of ceramic members is mounted on top of the beams, and aluminum-clad tar paper sheet is fixed to this. The roof is covered with red tiles on wooden slats and includes all necessary accessories. Roof drainage is done with galvanized gutters and downspouts that direct water to the main drainage culverts.
The window frames are made of bright- or dark-colored aluminum profiles and the glass is 8-10 mm thick, whether transparent, blue- or bronze-colored. The windows are sliding or swinging types and all have insect-proof wire screens. The exterior doors are made of solid wood, and come in several optional colors. The outer door lock is a German product, with a high quality locking mechanism. The interior doors are 0.90 or 0.80 m wide and 2.10 m high. They are made of laminated wood panels with polished or chromed brass knobs. We offer sliding or folding glass doors for the patio doors.
The patio and the interior floors will be covered with ceramic tile and sealed at the wall with a baseboard. Natural flagstone, hardwood or parquet floors are available as alternatives.
In the bathroom, the walls are completely clad with tiles, while in the kitchen they are covered only up to a height of 60 cm. Porcelain toilets are available in different colors. A toilet and a bidet are installed in the bathroom.
The hand washing sink consists of a granite base (color of your choice) with a 60 cm wide sink. The shower is covered with ceramic tiles. The bathtub or Jacuzzi can be acrylic, or enameled steel at extra cost. A toilet and porcelain sink are installed in the guest bathroom. All fixtures are equipped with one or two chrome faucets.
The drains are PVC pipes with a separate sewer pipe. Potable water lines in the building are all plastic pipes. The domestic hot water supply is heated with electric heaters. In the bathroom, a 60-100 liter-capacity thermal water heater is installed. Water heater volume depends on the number of inhabitants. Besides water supply in the kitchen and the bathroom, connections are provided for a washing machine and a dishwasher. There are taps located on an outside wall and in the garden (by the barbecue grill or pool).
The electrical installation includes the grounding electrode and all fixtures, including the fuse box, the service disconnect and several types of outlets. The wiring is run through conduits under the plaster or flooring. Conduits are planned for antenna, telephone and internet cables. The switches and outlets are made of plastic; color is optional. The layout of switches, outlets, the telephone and the antenna is defined in the installation plan.
Roof overhangs and the eaves, including the side overhang, are enamel-painted. A chimney (20 cm) is available for connecting to a wood stove or fireplace.
Throughout the property, roads and access to the house are paved and covered with fine gravel, and the grass is leveled.
