Home renovation: how much does it cost?

Before starting any renovation project, it is recommended to clearly define your objectives:

  • Increase the value of the property
  • Reduce energy costs (often due to poor insulation)
  • Improve the comfort of people living in your home

Scope of your home renovation

Once you have set your goals, next step is to establish the scope of the renovations needed. The scope will define certain decisions such as for example the need to hire an architect (or technologist) and an engineer.

Minor renovations Standard renovations Major renovations

Do I need an architect or a technologist?

In general, in a residential environment if your renovations impact the structural integrity, the exits and their access, the exterior envelope as it is the case for house extension, reconstruction or new construction projects, you will need plans made by an architect or technologist.

The architect and the technologist are related practices, the main difference is the extent of their responsibilities. In fact, according to the law on architects (articles 16 and 16.1), a technologist can only produce and sign plans for residential and commercial or industrial construction and renovation projects with an area of less than 3,200 ft2. An architect has no restriction and can sign any type of architectural plan.
