Renovating a property in Geneva is a major investment that requires method, expertise and foresight. In this article, we cover the key points to know before launching your project.

Defining your project

Before any work begins, clarify your goals: improved comfort, resale value, energy performance or compliance. This step drives the budget, schedule and choice of craftsmen.

The Geneva regulatory framework

The canton of Geneva enforces precise rules regarding building permits, heritage protection and energy standards. Working with local professionals avoids administrative roadblocks.

Controlling your budget

A detailed, line-by-line quote is essential. Always plan a 10–15% margin for contingencies. At Réno Suisse, our estimates are transparent and binding.
