With the expertise passed down from our patriarch I.G de Leon, a protege of the celebrated Italian sculptor F.R Monte, Landmark Builders continues a rich tradition of excellence in the world of architectural pre-casting that began in 1926. Migrating from a humble shop in Singalong, Manila, to a state-of-the-art precast plant in Mambugan, Antipolo, the Landmark Builders family has expanded and rebranded over the years without losing sight of our commitment to quality and the art of pre-casting.
