A generally flat composite structure has building blocks in the form of a plurality of multipurpose plastic building components. Each of the components includes an encompassing outer frame having a lateral surface and an interior. At least one coupling device is disposed at the lateral surface for joining two adjacent building components. Crosswise members and lengthwise members divide the interior of the outer frame into a grid of individual openings. The outer frame and the crosswise and lengthwise members are formed of plastic waste having been previously comminuted, then melted down and then injected or cast into a suitable mold. A method for laying out the components includes seeding or grassing down the components individually or in the composite structure before laying out the components, and then laying out the components in a seeded or grassed down (vegetated) state.
