About ZELIY

Engineering beyond
the standard

ZELIY Engineering Co., Ltd is a premium construction and engineering firm deeply rooted in Cambodia, with design offices in France. We operate at the intersection of structural precision and architectural ambition — building projects that demand expertise most firms simply cannot provide.

From the French Embassy to the Alliance Française, from luxury island retreats to high-security private shelters, our portfolio reflects a commitment to excellence that spans 20 years and three countries.

We are proud members of EuroCham Cambodia and work alongside official institutions, diplomatic missions, international NGOs, and the most discerning private clients in the region.
