  • Respect for the environment: Unlike traditional demolition, controlled demolition makes it possible to minimize construction waste and noise pollution for local residents.
  • Economic optimization: Recoverable elements from demolition can generally be sold or reused in the renovation, reducing the overall cost of the project.
  • Heritage conservation: Controlled demolition preserves the historical and architectural elements of an old house while improving its energy performance and functionality.

Compliance with regulations regarding demolition and reconstruction

When it comes to renovating an old house, legal and regulatory requirements must be taken into account. Thus, several administrative authorizations may be necessary before any intervention:

  • The building permit,
  • Urban planning authorization,

Controlled demolition techniques for the renovation of old houses

Selective demolition

Selective demolition consists of partially dismantling a building, keeping only the elements that will be incorporated into the new project. This technique requires meticulous work and technical expertise in order to preserve the existing building. The interventions carried out in this context include:

  • Cutting floors and stairs,
  • Removal of partitions and windows,
  • Removal of electrical and sanitary equipment.

Management of waste from controlled demolition

Controlled demolition generates a significant volume of construction waste which must be treated and disposed of in accordance with current regulations. It is therefore appropriate to put in place a global policy of waste management, including:

  • Collection and processing by specialized channels.

The choice of ecological materials and techniques for renovation

  • Natural materials like straw, hemp or wood,
  • High-performance insulators of plant or mineral origin,
  • A bioclimatic design to optimize solar gain.

Thus, by resorting to controlled demolition as part of the renovation of old houses, it is possible to combine respect for architectural heritage, energy performance and preservation of the environment.
