In any reform or renovation of a structure, consideration must be given to possible energy savings, as well as to any existing "Thermal Regulations (RT), which among other things define the energy performance levels") that must be implemented.

Wood

Wood is versatile and flexible, making it the easiest building material for renovations, and wood buildings can be redesigned to adapt to changing needs. Few homeowners or professional remodelers have the skill and equipment necessary to modify steel or concrete structures.

When analyzing the embodied carbon in building materials, wood is often labeled as the most sustainable. This is because it sequesters carbon which, if certified as sustainable, will significantly reduce the carbon embodied in buildings. This makes it a low-emission option as a construction material for a general building and for renovations. [7]​.

And finally, wood is without a doubt the material par excellence that best represents a vision of the "circular economy", since it reduces the environmental cost in terms of its disposal or destruction at the end of its useful life cycle, after numerous reuses. [8]​.

Plastic

Plastic has gained popularity in the renovation sector thanks to its versatility, durability and low cost. This material, primarily composed of synthetic petroleum-derived polymers, is used in a variety of applications, from coatings to thermal insulation and window components. Its waterproof properties make it ideal for humid environments such as bathrooms and kitchens, while its wear resistance and ability to imitate natural materials make it an attractive option for floors and walls.[9]​ Additionally, plastic is easy to maintain and clean, contributing to its preference in high-traffic areas. However, its environmental impact remains an issue of concern, which has driven the development of recyclable and biodegradable options in the renovation market.[10]​.

Technical progress today allows renovations and transformations that a few years ago were almost impossible to carry out.
