Floor for a modular enclosure

A floor for a shed comprising:

• a floor panel constructed from blow-molded plastic and including a generally planar first surface, a generally planar second surface that is generally spaced apart from the first surface by a distance, and a hollow interior portion that are integrally formed during the blow-molding process as part of a unitary, one-piece structure;
• a first pattern disposed on the first surface of the floor panel, at least a portion of the first pattern extending towards the second surface, the first pattern being integrally formed in the floor panel as part of the unitary, one-piece structure, the first pattern including one or more downwardly extending elements, the downwardly extending elements having generally the same shape, size and configuration, the downwardly extending elements including a lower surface that is spaced apart from the generally planar lower surface by a gap;
• a second pattern disposed on the first surface of the floor panel, at least a portion of the second pattern extending away from the second surface, the second pattern being integrally formed in the floor panel as part of the unitary, one-piece structure, the second pattern including one or more upwardly extending elements, the upwardly extending elements having a different shape, size and configuration than the downwardly extending elements;
• and
• at least two depressions formed in the second surface of the first floor panel and extending towards a portion of the first pattern, the depressions including an end that is disposed away from the second surface and disposed at least proximate a portion of the first pattern that extends towards the second surface, the depressions having a length that is equal to or less than a distance separating the portion of the first pattern that extends towards the second surface and the second surface, the depressions being sized and configured to increase the strength of the floor panel, wherein the end of the depressions contacts an inner portion of the first pattern disposed on the first surface of the floor panel;
• wherein the downwardly extending elements of the first pattern are disposed between the generally planar upper surface and the generally planar lower surface of the first floor panel;
• and
• wherein the upwardly extending depressions are disposed between the generally planar upper surface and the generally planar lower surface of the first floor panel.
