Construction company Parkd has sold its first prefabricated double-storey park to client City Subaru Perth for $690,000 in a deal that gives the ASX-listed minnow a welcome cash injection.

Parkd will also save the $200,000 it had budgeted in case it needed to take apart the lightweight concrete structure it built last year in half the time of a traditional concrete build and at a 35 per cent saving.
