Asahi Kasei Homes, which already owns one of the largest home builders in NSW in NEX Building Group, is taking advantage of lower borrowing costs in its home market of Japan to expand into land development in Australia.

The Japanese home builder, part of Tokyo-listed Asahi Kasei Corporation, aims to develop sites initially with as few as 100 lots a year and boost that to a yearly 350-500 lots for low-and medium-density homes over the next decade, the company said.
