Grass pavers for increasing visible green space

Abstract

A set of grass pavers for creating a paver arrangement is provided. Each grass pavers comprises intersecting longitudinal members and transverse members forming an inner opening for growing grass. Pairs of adjacent member extremities form partial openings configured to form complete openings when a 5 grass paver is assembled with adjacent grass pavers. The longitudinal members and/or the transverse members have recessed portion(s) having an upper face extending below the exposed top face of the unitary body. The recessed portions are hidden by grass when the grass paver is installed and in use in the paver arrangement. The grass paver have an overall surface area delimited by the 10 extremities of the longitudinal and transverse members, and a void surface area corresponding to a sum of the inner opening area and the partial opening areas. The void ratio, defined as the void surface area over the overall area, is greater than 50%.
