Technical specifications and interior finishes: avoiding unpleasant surprises in Geneva

Technical specifications and interior finishes: avoiding unpleasant surprises in Geneva

When buying off-plan in Geneva, the excitement of discovering a future home can sometimes overshadow a crucial step: analyzing the technical specifications and interior finishes. This document constitutes the contractual basis of your acquisition and defines exactly what will be delivered.

Understanding technical specifications: the foundation of your project

The technical specification details the materials, equipment, and services planned for the construction. In Geneva, this covers elements like reinforced concrete, thermal insulation, or interior wall finishes.

Do not settle for illustrated commercial brochures. It is in the technical pages that the details lie, making the difference between a high-end home and a standard build.

It is essential to verify the nature of the materials used. For example, external thermal insulation is now the standard, but the quality of finishes can vary significantly from one project to another.

Buyer-Requested Modifications (TMA): a double-edged opportunity

Modifications allow you to customize your future apartment, such as moving a partition or choosing specific floor coverings. While this flexibility is a major advantage, any change must be technically validated to comply with current safety standards.

However, be wary of costs, as surcharges requested by contractors can be high. It is advisable to negotiate these points as early as the reservation stage, ensuring that the base services are of sufficient quality to avoid excessive upgrade costs.

Points of vigilance when choosing finishes

Choosing finishes is often seen as the most enjoyable part, yet this is where misunderstandings are most frequent. Here are some points to check:

  • The range of materials included in the sale price: check if the price per square meter meets your expectations.
  • The quality of sanitary and kitchen equipment: ask for specific brands and models.
  • Wall finishes: ensure the specification includes a finishing paint and not just a base coat.
  • Finishing profiles: they ensure the durability and aesthetics of your floors; do not overlook them.
