Residence: cost, levels and upgrades

Short answer

A Residence makes room for more zombies: every level adds 12 to your horde cap, and you can build as many as you have pads for.

What it does

Binding research sets your horde cap at 60, rising to 96. Every finished Residence adds 12 zombie room for each of its levels on top of that, so a level-5 Residence is worth 12×5 more.

Unlike most buildings a Residence has no overall ceiling: stack as many as you like. Each copy you already own makes the next one cost 3 times more, so the room gets dearer the more you have.

A Residence under construction adds nothing yet. Room only matters when you have the serum and biomass to fill it.

Tips

Build one early if you keep bumping into the cap, and upgrade it before you build a second: levels are cheaper than new copies.
More zombies only help if you can bind them. Check your serum and biomass before you add room.
A Residence can be swapped for another building with Replace if you need the pad back.
