DETAILED DESCRIPTION OF THE DRAWINGS

[0052] The outdoor feature 10 shown in FIGS. 1 and 2 is generally cube-like and would typically have sides with a length in the region of 1 m to 1.5 m. For convenience, it is referred to herein as a bio-tower. As can be seen from the drawings, the bio-tower 10 is of modular construction, being formed, in the case of the illustrated embodiment, of four sections 12, 14, 16 and 18 stacked vertically one above the other.

[0053] The bio-tower 10 in FIG. 1 is shown as a stand-alone feature but this need not be the case. Several bio-towers can be positioned next to one another and they need not all have the same number of stacked sections. The bio-towers may be locked or connected together, with access from one habitat in one bio-tower directly connected to a similar habitat in the next bio-tower. Being modular, the height of each bio-tower may be increased or decreased by adding or removing sections.

[0054] The aim of the invention is to provide a decorative feature that is also designed to increase biodiversity. The top of each bio-tower forms an area in which plants can grow. In the illustrated embodiment, a soil-filled container 20 is located at the top of the bio-tower 10 and is surrounded by a drained trough 22 defined between it and the surrounding uppermost section(s) 16 and 18 of the bio-tower 10. In the illustrated embodiment, the soil-filled container rests on a plastic tray 27 (see FIG. 8) that may be filled with loose stone, and it in turn is supported by a floor member 40, which may be a metal plate. As earlier mentioned, it would be alternatively possible to form a tray of metal rather than a plastics material and it would be connected to the soil filled container 20. The dry volume disposed beneath the growing plants and the wet habitat defined by the tray 27, are separated into different compartments that are sheltered from the elements and designed to provide habitats suited to different animal species.

[0055] Each of the sections 12, 14 and 16 comprises a frame having four vertical sides that are connected to one another at the corners by means of load-bearing structures 30, which are described in greater detail below by reference to FIGS. 3 and 4. The sides are made up of tongue and groove boards which mate with one another when the sections are stacked one above the other as shown in FIGS. 1 and 2. This establishes a form-locking engagement between the sections, preventing them from sliding relative to one another. The tongue and groove boards can be made of wood, or any composite material capable of withstanding the weather conditions. In the illustrated embodiment, the sides of the individual sections are not called up to support all the weight of the soil and plants in the growing area, as much, if not all, of the load is supported by the corner structures 30. It would however be alternatively possible for the lower section to be made of metal and to have sufficient strength and rigidity to support the weight of the entire bio-tower

[0056] As illustrated by way of example, each of the load-bearing corner structures 30 is made up of two components of which the first is a tube 32 of square cross section of which only the projecting lower end is seen in FIG. 3. The sides of each section are directly secured to this tube 32.

[0057] In the alternative construction shown in FIG. 3a, each corner comprises a square section tube with two projecting flanges to which the sides are screwed. In this embodiment, a pole may be inserted into the central holes of the square section tubes of the different overlying sections one they have been aligned with one another.

[0058] The second component is a bracket 34, shown separately in FIG. 4 that has four vertical plates 34a, 34b, 34c and 34d that are at rights angles to one another. The two central plates 34b and 34c are secured to the tube 32. The two end plates 34a and 34d are secured to sides of the section and additional have bent end flanges 36 at their upper and lower ends. These flanges 36 serve to transmit load between the sections and may also, if desired, enable adjacent sections to be bolted to another. As can be seen from FIGS. 3 and 4, the tubes 32 and the brackets 34 have holes for receiving fixings to secure them to one another and to the sides of each section.

[0059] In an alternative embodiment, not shown in the drawings, the plates 34b and 34c are extended upward further than the flanges 36 and bent to form a spigot of square section that can be received in the lower end of the next higher tube 32 in order to ensure vertical alignment of the tubes 32.

[0060] The weight of the soil-filled container 20 rests on a plastics tray 27 that is filled with loose stones and it is itself supported by a floor member 40 that is sandwiched between the sections 14 and 16 and that rests on the flanges 36 at the four corners of the section 14. To support the floor member 40 further, the two sections 12 and 14 beneath it are formed with central partitions 12a and 14a. These partitions may be made from the same material as the sides of the sections and are secured to them by means of angle brackets 38.

[0061] Two of the sides of the lowermost section 12 and its central partition 12a are each formed with two cut-outs 42 to receive the tines of a forklift truck or lifting straps connected to a crane. These allow the bio-tower 10 to be moved without the need for it to be dismantled.

[0062] Additionally, the other two sides of the lowermost section 12 are formed with cut-outs 44 that can be used to receive boxes 50, as shown in FIG. 5. Depending of the type of fauna to be provided with a habitat in these boxes 50, they may either be left wide open or their entrances may be restricted by means of a closure panel 52, as shown in FIG. 6. Such habitats can be individually designed by their shape, positioning and contents to attract different animal species. For example, boxes with a small entrance at a high level would be suited to birds, while boxes at ground level and with larger entrances are better suited to hedgehogs. Furthermore, the different habitats may have different humidity, with some being wet and others dry. If a compartment is required to have water, an internal drainage tube may connect it to the tray 27 that can collect rainwater or be filled by a hose through a pipe.

[0063] The volume beneath floor member 40 is designed to be filled with a material, such as bark or stones, that can serve as bedding and possibly as food for some animals that can access this space through the openings 42. Removable inspection/access panels 54 are provided in the section 14 for maintenance, for example to allow replacement of the bark or wood material. As an alternative to the panels 54, it may be possible in an alternative embodiment to raise the solid cage and tray as described above.

[0064] In this way, the volume of the bio-tower beneath internal floor member can be designed to provide multiple habitats suited to different flora, fauna and fungi.

[0065] The part of the bio-tower above the floor member is not sheltered from the elements and can receive rainwater. In the illustrated embodiment, it is separated into two different regions by the provision of the soil-filled container 20. This need not, however, always be the case because the entire top section could be a tray filled with soil. The advantage of using a soil-filled container is that it can provide vertical separation between plants and also that it allows the soil conditions within the container 20 to differ from the those in the surrounding trough 22. Its advantages are therefore both aesthetic and functional.

[0066] To reduce the weight of the soil-filled container 20, it may be formed of a wire basket 21 lined with a plastics membrane 23 that preferably extends to the top of the basket 21. The plastics membrane may be woven or, if made of a continuous sheet, holes may be provided or formed in it to allow water to drain. The sides of the wire basket 21 projecting higher than the sides of the top section 18 of the bio-tower 10 can be used for hanging insect hotels 25. It may alternatively be preferred to form the soil-filled container in a more robust manner as described above.

[0067] As the tray 27 disposed beneath the trough 22 and the soil-filled container contains loose stones or crushed rocks, it can collect rainwater and serve for irrigation. The roots of plants in both the trough 22 and the container 20 may spread into the tray 27. The tray itself forms a suitable habitat for species that require a wet environment and it is possible to provide openings in the supporting metal floor 40 to provide access to this habitat from the underside of the bio-tower 10.

[0068] It is desirable to enlarge the trough 22 by inclining the sides of the uppermost section 18 of the bio-tower 10 in the manner shown n FIGS. 1 and 2. One of the sides 60 of such an uppermost section 18 is shown in FIG. 7. The side 60 is formed of the same boards as the sides of the remaining sections and thus has a tongue 62 and a groove 64. However, in this case, the corners of the section are constructed differently and include a Y-shaped bracket 68 designed to receive a small triangular insert as shown in FIGS. 1 and 2.

[0069] Because of the inclination of the sides 60 of the uppermost section, their groove cannot fully receive the tongue projection from the next lower section. For this reason, it is desirable to fit the sides with brackets 66 to locate the uppermost section on the section beneath it.

[0070] The bio-tower 10 of the preferred embodiment of the invention are designed for ease of storage, transportation and assembly. It is possible for the entire bio-tower 10 to be flat packed or the individual sections may be pre-assembled. Each section or module is of a size permitting it to be moved without the need for heavy lifting equipment and assembly requires no more than stacking of the modules above one another and locating the internal floor member 40 and the tray 27 at the designed height. Should it be necessary to move the bio-tower after a length of time, it is capable of being lifted without the need for it to be dismantled.

[0071] It should be clear to the person skilled in the art that various modifications may be made to the embodiments of the invention described above without departing from the scope of the present invention as set forth in the appended claims. In particular, the shape, size and number of modules, as may the number of separate habitats defined within the bio-tower, be it by sub-division using partitions or by additional of removable boxes or drawers. Furthermore, while it is desirable, from the point of view of ease of assembly, for the modules merely to need to be stacked one above the other, it would alternatively be possible to provide fixings to secure adjacent modules to one another.
