At the start of the recession during early 2020 and 2021, land releases for owneroccupier (such as a 4 bedroom single-storey dwelling) housing were limited. Therefore, only few construction companies were in action as the costs of borrowing money from banks also slowly started decreasing. But there are no barriers to entry or exit in the construction industry such as for building owner-occupied housing.
