CLAIMS

1. A building element (20) for forming a part of a modular housing unit (24), the building element (20) comprising:

- a load-bearing wood-based panel (12); and

- a sandwich panel (10) fixedly connected to, and substantially parallel with, the wood-based panel (12);

wherein the sandwich panel (10) comprises two outer layers (14) and a core layer (16) between the outer layers (14).

2. The building element (20) according to claim 1, wherein the wood- based panel (12) comprises at least two non-aligned wood layers (18).

3. The building element (20) according to claim 1 or 2, wherein the wood- based panel (12) comprises at least two differently oriented wood layers (18).

4. The building element (20) according to any of the preceding claims, wherein the wood-based panel (12) comprises cross-laminated timber.

5. The building element (20) according to any of the preceding claims, wherein each of the wood-based panel (12) and the sandwich panel (10) are prefabricated.

6. The building element (20) according to any of the preceding claims, wherein the sandwich panel (10) is directly connected to the wood- based panel (12).

7. The building element (20) according to any of the preceding claims, wherein the outer layers (14) are of the same type.

8. The building element (20) according to any of the preceding claims, wherein the outer layers (14) are waterproof.

9. The building element (20) according to any of the preceding claims, wherein the core layer (16) is an isolation layer.

10. A modular housing unit (24) comprising at least one building element (20) according to any of the preceding claims.

11. The modular housing unit (24) according to claim 10, wherein the at least one building element (20) constitutes one or more load-bearing walls (26) of the modular housing unit (24).

12. A modular housing unit (24) comprising two building elements (20) according to any of claims 1 to 9, wherein the two building elements (20) constitute two perpendicular load-bearing walls (26) of the modular housing unit (24), and wherein the two building elements (20) are directly connected to each other.

13. A building (22) comprising at least one modular housing unit (24)

according to any of claims 10 to 12.

14. A building (22) comprising at least two modular housing units (24) according to claim 10 to 12, wherein an upper modular housing unit (24a) of the at least two modular housing units (24) is arranged on top of a lower modular housing unit (24b) of the at least two modular housing units (24).

15. A building (22) comprising at least two modular housing unit (24)

according to claim 11 or 12, wherein at least one upper modular housing unit (24a) is arranged on top of at least one lower modular housing unit

(24b), and wherein at least 80 % of the load of the at least one upper modular housing unit (24a) is taken up by the one or more load-bearing walls (26) of the at least one lower modular housing unit (24b).

16. A method of assembling a building element (20) for forming a part of a modular housing unit (24), the method comprising:

- providing a load-bearing wood-based panel (12);

- providing a sandwich panel (10) comprising two outer layers (14) and a core layer (16) between the outer layers (14); and

- fixedly connecting the sandwich panel (io) to the wood-based panel (12) substantially parallel with the wood-based panel (12).
