A paving block for covering ground, floor and like surfaces. The paving block is generally planar with a vertical dimension. The upper and lower planar surfaces and the vertical sides define a pentagon. The pentagon has three longer sides and two shorter sides. Two of the longer sides are equal. The third longer side is at least as long as the two equal longer sides. The two equal longer sides are joined at one end at a 90.degree. internal angle. Each is joined at its opposite end to one of the shorter sides at a 90.degree. internal angle and each shorter side is then joined at a 135.degree. internal angle to the third longer side. The third longer side opposes the right angle between the two equal longer sides and is bisected by a line bisecting the 90.degree. angle between the two equal longer sides. The pentagonal paving block may be used to create homogeneous designs or in combination with a square paving block, the external sides of which are equal in length to the adjoining longer sides of the pentagonal block.
