The Town needs homes that young people and families can afford. Especially those who want to work in the Town and do not have very high incomes or inherited capital.
What is the root of the problem?
The price of homes in Henley is hugely inflated by the demand to live here and by the shortage and hence the cost of land. For new builds in the town to be within in the reach of first-time buyers, the value of all property must first fall. Even if this could be engineered, it would be highly contentious.
