The choice of materials depends on the desired effect; while natural stone can provide a more rustic aesthetic, paving or slabs can be used to create elegant contemporary looks.

In addition, the use of gabions can have a unique visual impact due to its textured surface. Regardless of the material chosen, care must be taken to ensure that all components are properly installed to achieve a satisfactory result.

Construction of an annex

When you decide to expand your home by adding an addition, it is important to remember that this type of renovation is not a small investment. However, the cost of the expansion is offset by the added value it will bring to your property. According to real estate experts, an addition can increase the overall value of your home by 5-20%. This means that the day you decide to sell your home, it should fetch much more than if it had not been expanded.

In addition, an addition has many practical benefits, such as extra space for entertaining guests or additional bedrooms if your family grows. It also offers customization options, so you can make sure your space perfectly meets all your needs.

In summary, investing in an addition is a great way to increase the value of your home and maximize the use of your living space!

Electrical work

An electrician’s job is to install, maintain and repair electrical systems. This can include wiring, circuit breakers, outlets, light fixtures, and other components needed to operate the electricity in a home or business. Electricians generally use specialized tools to do their work safely.

In addition to installation and repair duties, electricians may also be responsible for inspecting existing electrical systems to ensure that they are safe and for resolving problems that arise during operation.

Roofing work

Roofing work includes installation, repair and maintenance of roofs. They include a wide range of services from replacing broken tiles and shingles to installing skylights and inspecting for hail damage or other weather events.

Roofers must be familiar with building codes and regulations to ensure that roofs are installed correctly and in compliance with safety requirements. They must also know how to use specialized tools such as power drills, saws, hammers and ladders.

In addition to these skills, roofers must have good problem-solving skills in order to identify potential problems with a roof before they become major issues.


Thermal insulation is an important element in building construction, as it acts as a barrier to prevent heat transfer between the interior and exterior of a structure.

Thermal insulation materials are specifically designed to reduce thermal energy loss or gain depending on their location in the building envelope. These materials typically include fiberglass, cellulose, foam board, mineral wool, sprayed or rigid foam and other specialized products. In colder climates, thermal insulation is essential to keep heat inside a building and reduce energy consumption; conversely, in warmer climates, it can be used to reduce cooling costs by helping to keep unwanted heat out.

In addition, properly designed and installed thermal insulation can improve occupant comfort by preventing drafts and condensation that can lead to mold and other health problems.


Facades are an important element in the construction of a building, offering both aesthetic and functional advantages. They can be made from a variety of materials such as brick, stone, concrete, wood, metal and glass, and have many different finishes. The installation of a façade requires careful planning to ensure that the structure is well supported and able to withstand environmental conditions for many years.

Façade repair and renovation are common tasks that must be performed periodically to maintain the structural integrity of the building. This may involve replacing or reinforcing existing materials with new elements, or applying a new coat of paint to freshen up the appearance of the building. In addition to these services, insulation should also be considered when renovating facades, as it helps protect the property from extreme weather conditions while reducing energy costs.

Painting facades can also have significant benefits when it comes to increasing their lifespan by providing additional protection against moisture and other elements. It is important to consult with professionals regarding the type of paint used so as not to damage the underlying materials or structures.
