5. 5 . The building system of claim 4 , wherein the plurality of connecting brackets are identical.
6. 6 . The building system of claim 1 , wherein a plurality of connecting inserts of the floor panel and/or a wall panel are in the form of apertures extending through the panel, wherein the building system is configured such that when each precast wall panel is positioned in a substantially upright position in the recess of the floor panel, an aperture of a first panel aligned with a threaded insert having a closed end of an adjacent second panel so that the first and second panels can be connected using a plurality of mechanical fasteners.
7. 7 . The building system of claim 1 , wherein the precast concrete floor panel comprises one or more recessed areas and one or more structural ribs arranged to extend through the one or more recessed areas.
8. 8 . The building system of claim 1 , wherein the pre-cast concrete roof panel comprises one or more recessed areas and one or more structural ribs extending through the one or more recessed areas.
9. 9 . The building system of claim 1 , wherein each of the plurality of cast-in inserts of the roof panel has a closed end and is positioned at an internal surface of the roof panel when the building structure is erected.
10. 10 . The building system of claim 1 , wherein the roof panel comprises a first end that forms a lower end of the roof panel, and a second end opposite to the first end that forms a higher end of the roof panel when the building structure is erected, wherein a wall panel supporting the first end of the roof panel is shorter in height than a wall panel supporting the second end of the roof panel.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a U.S. national phase under 35 U.S.C. § 371 of International Patent Application No. PCT/AU2021/050487 filed May 24, 2021, and claims the priority of Australian Patent Application No. AU 2020901731 filed May 27, 2020. The disclosures of all such applications are hereby incorporated herein by reference in their respective entireties, for all purposes. TECHNICAL FIELD The present invention relates to a building system for erecting a building structure and a method of making and assembling the building system to erect the building structure. BACKGROUND The process of erecting a building structure is typically a costly and cumbersome exercise. Prefabricated building structures are building structures that include components that are manufactured off-site and, prior to the process of erecting the building structure, the components are taken to a building site. The components are typically made in a factory and shipped to the building site. At the building site, the components are assembled together to erect the building structure. However, with conventional prefabricated building structures, there may still be a lot of on-site manufacturing and wet work involved to erect the building structure and make the building structure structurally sound. The process of assembling the components of a conventional prefabricated building structure on-site typically are a cumbersome process and requires skilled labour as well as specialised machinery. This increases the cost for erecting the building structure. It would be advantageous if embodiments of the present invention would simplify the process of manufacturing and assembling the building system to erect the building structure or at least provide an alternative to conventional prefabricated building structures. Any discussion of documents, acts, materials, devices, articles or the like which have been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each claim of this application. Throughout the specification the word “comprise”, or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps. SUMMARY Embodiments of the present invention relate to a building system for erecting a building structure, the building system comprising: a plurality of precast transportable concrete wall panels; each wall panel comprising a reinforcement structure and a plurality of cast-in connecting inserts, each connecting insert being located at a predetermined position; anda precast transportable concrete floor panel, the floor panel also comprising a reinforcement structure and a plurality of cast-in connecting inserts, each being located at a pre-determined position, the floor panel further comprising a recess along at least a portion of a perimeter of the floor panel; andwherein the building system is configured such that when each precast wall panel is positioned in a substantially upright position in the recess of the floor panel, connecting inserts of two adjacent panels align so that the panels can be connected using a plurality of mechanical fasteners. Embodiments of the present invention provide significant advantages. In particular, by providing a recess along at least a portion of the perimeter of the floor panel, the wall panels can be precisely positioned when the building structure is erected. Even more so, this particular configuration may assist in water proofing of the building structure as water is restricted from entering an internal cavity of the building structure. Also, by positioning the connecting inserts of the panels at predetermined positions to substantially align when the building structure is erected enables a simplified process of erecting the building structure. Furthermore, by providing the floor panel and the wall panels as pre-cast transportable concrete panels, erection of the building structure can be simplified. Moreover, transport of components of the building structure may be improved as the panels can be transported in a flat pack. In one embodiment, the recess of the floor panel has a width that is substantially identical to a width of the connecting wall panel. This has the advantage that the wall panels can easily be positioned to ensure the correct alignment of the connecting inserts for connecting the panels to each other using mechanical fasteners. In an embodiment, a connecting insert may comprise an attachment for attaching the insert to a support structure, wherein the support structure is attachable to the casting bed in which the panel is cast. In this way, precise
