1. A living construction material comprising:
a loaded solid object comprising cells of a urease-producing organism and cells of a urea-producing organism, wherein the loaded solid object is loaded with spores and vegetative cells of the urease-producing organism and the urea-producing organism via placement of a solid object in a composition containing dry organisms such that the organisms are retained within or on a surface of the solid object; and
a carbon source, a nitrogen source and a calcium source,
wherein the loaded solid object is configured to form calcium carbonate within, around, or external to the loaded solid object for a period of six months or more using the cells of the urease-producing organism and the urea-producing organism, and the carbon, nitrogen and calcium sources, while the loaded solid object is immersed entirely within a marine environment.
