The inaugural month-long fair is planned for a greenfield site on the outskirts of Inverness. It will feature 53 newly built homes selected by the Royal Incorporation of Architects in Scotland. Subsequent events will be staged in different locations around the country.
"We want to take a positive step towards changing the housing market," said co-ordinator Fiona Porteous. "We need to show what can be achieved if we emphasise the better design of homes and communities."
The homes will be sold off or made available for rent after the event. However, controversy has dogged the government-backed fair because the proposed site is designated as a green wedge in the Inverness local plan.
Highland councillors are due to consider detailed proposals for the housing fair next month before Scottish ministers take a final decision.
