City life is deprived of adequate private/green outdoor space. Most property owners in the city are under-leveraging what could be their most valuable asset: the roof! Top-Yard makes it simple for owners to create green livable space on city rooftops. We've leveraged commonalities between building types and developed a deck "in a box" - a modular roof deck with streamlined implementation. It's a "universal", turnkey system to scale rooftop oases.
