About Nathan

With 10 years of experience in the green spaces sector in Île-de-France, I offer my services as a freelancer to support professionals in cost estimation, technical assessment, and the preparation of tender documents.

My expertise covers landscaping projects (rooftop gardens, facade greening, green walls, VRD, furniture, planting, irrigation, etc.) in private or public markets.

I work with landscapers, architects, general contractors, and developers who seek a technical perspective, reliable estimates, and clear deliverables without mobilizing internal resources.

➕ Responsive, rigorous, accustomed to site constraints and client expectations, I help you save time, secure your budgets, and structure your offers.
