We don't build housing, builders do. We simply decide what is permitted to happen. We could eliminate restrictions on construction and that would help but the rate of housing growth would still be limited by money available to pay for new housing, which is a lower bound to affordability. It's actually a worse problem than it sounds for, if we're decreasing building restrictions then we're slowing price growth and decreasing the attractiveness of housing to investors. To accelerate affordability, we probably also need to subsidize or at least incentivize then.

That gets to be fairly expensive so where's the money going to come from? My proposal is a national growth tax, whose money is redistributed from areas which don't grow to those which do. That money will be used to pay for infrastructure improvements needed to house those people as well.
