Construction of Dunedin's first co-housing community, which will accommodate about 60 people, will begin at the site in August.
High St co-houser and open day co-ordinator Jan Burch said 22 of the 24 passivhaus units at the site had been bought and yesterday there was lots of interest in the remaining two.
The open day was an opportunity to demystify co-housing, which some considered an option only for the elderly or eccentric, she said.
''It is simply for people who want to share a meal together every now and then.''
About 280 children plus their families attended the event, which offered obstacle courses, a bouncy castle, virtual reality headsets and toys from the Mornington Toy Library to play with.
Ms Burch said the organisers were so busy they forgot to tell Kaitaki Norman-Pere she had won the teddy bear of the day.
The co-housing facility would open in 2019.
