Phase 1: The structural work, birth of the volume of the house

During the structural work, the house really takes shape. Walls, framework, roofing, the structural work brings together everything that contributes to the solidity and stability of the building.

 

1st step: treat the base to avoid cracks

Good foundations

Invisible and yet primordial, foundations support the weight of the house. Their depth and their nature vary depending on the terrain. There are different types of foundations, the most common being the sole continuous concrete or continuous footing. Adapted to resistant and relatively flat soils, it takes place in a shallow trench (from 50 cm to 1 m). To adapt to sloping land, manufacturers can opt for stepped foundations.

The manufacturer makes every effort to avoid differential settlements which are one of the main causes of cracks, as shown Construction Quality Agency in this document on pathologies of shallow foundations.

Maisons Sic takes care of its foundations to avoid cracks in the masonry.

The basement and the crawl space

These are the first rows of concrete blocks, bricks or stones that rest on the foundations and are placed under the From. The height differs depending on whether you want the ground floor slab to rest on a basement, a crawlspace or directly on the foundations. The creation of a basement has many advantages, but is an expensive operation. More economical, the crawl space separates the floor from the ground, which avoids the risk of compaction or cracks that are frequent on certain floors. THE clay soils in particular, frequent in Toulouse region, swell or shrink depending on the humidity, as indicated by this Logic-Immo article. The house is also more healthy since, associated with a watertight barrier placed on the basement, crawl space block them capillary rise.

2rd step: Insulate, pour the slab and place the networks and the sanitation

Avant to pour the slab, it is necessary to set up, the cables ofpower supply as well as water inlets and the pipessewage disposal and sewage. From this stage, the slopes are planned and respected to guarantee perfect flow over time.

House Sic, pays particular attention to this crucial step. The pipes are thus temporarily blocked to prevent the rubble from falling inside during the work.

3rd step: raising the load-bearing walls

The walls then rise according to the planned plans, with the reservations for the different doors and windows. The thresholds and window sills are put in place as well as the lintels, which retain the load above the joinery. At Maison Sic, builder de Toulouse à Bordeaux , the walls are reinforced with a reinforced concrete belt in the upper part. Tied to a level on the gable walls, they aim to avoid the risk of cracking related to the pressure of frame.

4rd Step: Design the roof

- Framing

La frame is usually in wood and sometimes in metal. Supporting the roof, the so-called traditional frame consists of farms, purlins and rafters that transmit the weight of the roof to the load-bearing walls. The frames at industrial farmhouses, are widely used today in new construction. Made up of thinner pieces of wood than traditional trusses, trusses offer a strong resistance thanks to their triangle-shaped design. They occupy a large area in the roof space who are then uninhabitable. Offering a good resistance/lightness ratio, they distribute the loads well, which avoids any deformation of the roof.

- The roof

+A sloping roof

As soon as the framework is finished, and a under roof screen installed, a roofer comes to lay the terracotta tiles, where the slates in the most frequent cases. The material chosen is a matter of taste but also of thelocal architecture, climate and regulations.

Terracotta is the most widely used roofing material. Durable and resistant, especially to frost, terracotta tiles come in different shapes and colors depending on regional specificities.

Slates are also very common in some areas, especially in mountainous areas such as the Pyrenees. Of great longevity, they are particularly resistant to bad weather.

Lost attics and tiled roof
In the frame, the farmhouses guarantee the good performance of the terracotta tile roof.
+ Terrace roofs

Made up of a single, very gentle slope, the roof terraces increase the number of square meters of a house. Covered with gravel, tile or vegetated, they can, if they are accessible, offer a new outdoor living space. The design and implementation must be particularly careful to avoid infiltration

5rd step: laying the joinery

Both windows and doors require special care during installation. Even the best performing windows will leak if not installed properly.

 

Phase 2: the finishing work, fitting out and equipping the house

Now out of water, out of air, the house is entering its second phase of work which aims to make it habitable. Interior fittings, insulation, plastering, coatings, plumbing, electricity, the finishing work includes all the work aimed at fitting out and equipping the house.

Thermal and sound insulation guarantees comfort and savings in the home.

1st step: Insulate the detached house in the South-West

- Thermal insulation

As energy is more and more expensive, saving it has become essential. As La Dépêche du Midi explains in this article. Placed on the exterior walls of the house (roof, exterior walls, ground floor slab), theisolation has for missionavoid heat loss of a detached house. The more the insulation will be performances, the more your house will be economic in use. In the long term, the initial investment will thus be largely compensated. The manufacturer's attention will be focused on tracking down thermal bridges. This is to avoid points of contact between warm indoor air and an uninsulated cold surface.

If it is possible to make todayexterior insulation, in France, the insulation is generally done by theshooting.

– Sound insulation, think about it when you build your detached house

Implementation between floors but also in the interior partitions of the house, a sound insulation aims to mitigate the sound transmission between two rooms of the dwelling in order to guarantee the tranquility and privacy of the inhabitants.

2rd step: Plumbing and electricity

Installed before laying the plasterboard, the networks (Electricity supply, heating, Hot water, cold water), are hidden from view in the partitions. THE'electrician will come back after the intervention of the drywaller for installing sockets, switches and lighting points.

3rd step: Interior partition and plastering

The now insulated walls and ceiling are then covered with plaster. Finally come the interior partitions which allow the future house to appear more clearly.

4rd stage: Heating, air conditioning, production of domestic hot water and ventilation

– Installation of equipment

The installation of the systems heating and domestic hot water production must be done according to the rules. Modern amenities like thermodynamic water heater or heat pumps, must guarantee energy savings and a good level of comfort. In particular, care must be taken to ensure that there is no noise, both indoors and outdoors.

– Installation of heat emitters

In addition to conventional radiators, it is also possible to install a floor heating. This one can be electric or to Hot water. The elements of these systems are placed on the insulation of the ground floor and embedded in the screed which will be used to receive the floor finish.

Placed under the screed, the underfloor heating guarantees the comfort of the house.

5rd stage: Electricity generation

The South West is a sunny region. When you build your detached house, you have to take advantage of it. THE photovoltaic panels produce electricity from solar energy. They settle on the roof.

6rd step: The facade finishing plaster

The latter is not only used to beautify the appearance of the detached house. It is also responsible for protect sustainably the facades bad weather. The application of the coating requires a certain know-how to avoid cracks and possible infiltrations which can damage the building. On certain strategic points, such as the connections between joinery and masonry, builders implement a trellis. It prevents cracking of the roughcast due to differences in expansion of the material or vibrations of the coffers. roller shutters.
