CLAIMS

What is claimed is:

1. A building block, comprising a body with an upper end and a lower end; one or more main compartments; one or more inner pass-through openings; a first set of tapered lateral protrusions defining a first lateral dove-tail passageway; and a second set of tapered lateral protrusions defining a second lateral dove-tail passageway, wherein the upper end comprises a first upper cut, a second lower cut, and one or more protrusions, the lower end comprises a first lower cut and one or more slots, and the body further comprises a plurality of holes configured to receive fixtures of a front separable cover and a back separable cover, the front and back separable covers are configured to substantially cover the one or more main compartments.

2. The building block of claim 1, wherein the one or more inner pass-through openings is configured to receive electrical or telecommunication wiring and/or plumbing connections.

3. The building block of claim 1, wherein the front separable cover comprises one or more planting pots.

4. The building block of claim 1 , wherein the fixtures comprise pins configured to be press- fit in the plurality of holes.

5. The building block of claim 1, wherein the body further comprises one or more grooves adapted to receive gaskets or protrusions of the front and back separable covers.

6. The building block of claim 1, further comprises a first joining member configured to connect two horizontally adjacent building blocks and is configured to be inserted in a space gap formed by mating the first lateral dove-tail passageway of two horizontally adjacent building blocks.

7. The building block of claim 1, further comprises a second joining member configured to connect two horizontally adjacent building blocks and is configured to be inserted in a space gap formed by mating the second lateral dove-tail passageway of two horizontally adjacent building blocks.

8. The building block of claims 6 or 7, wherein the first joining member comprises two opposed intrusions adapted to receive two opposed extrusions of a vertically adjacent second joining member.

9. The building block of claim 1, wherein the one or more slots of the lower end are configured to receive one or more protrusions an upper end of a vertically adjacent building block, thus achieving an interlocking connection between two vertically adjacent building blocks.

10. The building block of claim 1, wherein the body has a shape substantially resembling a trapezoid.

11. The building block of claim 1 , wherein the body has a shape substantially resembling a hexagon.

12. A building system comprising a plurality of building blocks of any of the preceding claims interlocked with each other, and a base.

13. The building system of claim 12, further comprising means for fixing the system against a rigid body.

14. The building system of claim 13, wherein the means for fixing the system against a rigid body comprises power screws, and/or fixing elements.

15. The building system of claim 13, wherein the fixing elements comprises multiple coaxial double-threaded elements that are able to move in a twisted movement relative to each other, and a flange.

16. The building system of claim 13, wherein the base comprises a plurality of fixing elements, and a lifting mechanism, wherein each fixing element is configured to receive a substantial part of the building blocks.

17. The building system of claim 16, wherein the lifting mechanism is configured to change the elevation of the building blocks with reference to a rigid body, the lifting mechanism comprises a scissors-type lift, and a handle in operable connection with the lift.

18. The building system of claim 12, wherein the base further comprises a fluid reservoir.

19. The building system of claim 12, wherein the base further comprises a fluid pump configured to pump fluid from a fluid reservoir to one or more main compartments of a building block.
