Firstly let's be clear that the supply of land is fixed. The only limitation is that of the housing that goes on top of the land - the amount, density and quality. Housing should be a highly financially attractive to build. The land under the housing should be highly unattractive as a financial asset. There is a clear difference between the two. The distinction can be made by taxing the capital gains from LAND very different from the gains from improvements. If you tax the capital gains from land at 75%, I promise you will get the same amount of building but a lot lower overall housing cost. You can also lower interest rates for housing construction/refurb companies but also remove the tax incentives for actual home ownership.
