About

A trusted partner for demanding real estate projects.

CG Talon was founded by Christophe Grabielle, a civil engineer certified MRICS, to support owners, investors and developers in the design and delivery of high value-added real estate projects.

The firm operates at the interface between technical challenges, financial objectives, ESG requirements and the real uses of buildings — accompanying the construction and renovation of complex assets: towers, hotels, residential, commercial, public and industrial infrastructure.

Its strength lies in rigorous project management, the anticipation of technical interfaces and a long-term oriented vision — each project designed to combine quality, sustainability and cost optimisation.
