Building a house

A house is not just any build. The mod validates the structure before accepting it, and an NPC only moves into an approved one.

The requirements​

Structure​

The space must be enclosed: walls and a roof with no gap for the check to leak through. Doors count as closed wall.

The interior is capped at 512 blocks. Past that the check gives up and rejects the house — the cap exists so an open cave is not mistaken for a mansion. (Unless you are trying to build the Mines of Moria, 512 blocks is usually more than enough).

Checking​

Point a House Blueprint at a registered bed.

House Blueprint

The tool will tell you whether the structure passed and, when it did not, what is missing. It also reports how many interior blocks were visited, and how many doors and chests were found.

Unloaded chunks get in the way

If part of the house sits in an unloaded chunk, the check flags the result as incomplete rather than rejecting it. Stand near the house when checking.

The house is identified by its bed​

This is the most important detail and the easiest to trip over: the house's identity comes from the bed.

What that means in practice:

  • Two beds in the same room can become two houses. (Oh my god, they were roommates...)
  • Breaking the resident's bed releases the house.
  • Moving the bed can read as a different house.

It is a known limitation, and turning it into an identifier of its own is on the roadmap.

Doors​

A door occupies four blocks, and two doors side by side form a double door. NPCs open and close them as they pass. (Hodor would be proud).
