Home


 * This page is about constructing a home. For tips on defending one, please see the House Defense page.

A  is a safe haven for players and NPCs where they can spend their nights without fear of attack. A home is typically also used as a player spawn point once a Bed has been acquired, and it may also be used as a place to store extra items for use at a later time. Each NPC requires their own room within a home, with a total of 11 rooms needed to house all of the NPCs as of patch 1.1.1. Homes can be built almost anywhere in the world, though some locations are safer than others.

For starters a simple home built on the surface near a forest is a good choice. Typically, the first home that a player will build is nothing more complex than a single room with walls made of Wood, a Wooden Door for an entrance, and Wood Walls for the background. A Wooden Table, Wooden Chair and a Torch is enough to make the room suitable for the first NPC, the Guide, to live in. More rooms can be added to a home at any time, and Wood Platforms offer a good way to move between floors within a home. Once a player has explored the world and acquired more resources, far more elaborate and decorative homes can be constructed.

Housing Menu
The housing menu is a feature first introduced in patch 1.1. It allows players to assign their NPCs to live in specific rooms and also to use the "housing query" option to check if a room meets the various requirements for an NPC to live there.

The housing menu is accessed by clicking on the house icon towards the upper-right corner of the screen in the player's inventory. Selecting housing query and then clicking on a room will return a message indicating the room's status. Selecting an NPC's portrait and then clicking on a room will hang that NPC's flag somewhere in the room, thereby assigning the NPC to live in that room. NPCs can be unassigned from a room by right-clicking on their flag within the room.

If an NPC's portrait does not show up on the right side of the screen when the housing menu is open, then either that world has not yet acquired that particular NPC yet, or the NPC is currently dead and will eventually respawn if there is suitable housing available.

Housing Query Messages
The following table describes all housing query messages that the player may see, and provides a link to the related requirement(s). Note that some of these messages can be combined when multiple requirements are not met. For example, one may see a message such as "This housing is missing a table and a chair." The table below does not cover all of these combinations explicitly, so keywords are indicated instead.

Requirements

 * These requirements are currently up to date for patch 1.1.2. For interested readers, the testing performed on NPC housing can be found in this blog post. See also: Bugs

This section lists all requirements that a room must meet for an NPC to be able to live in it. Note that for a player to set their spawn point with a Bed, only the Walls, Minimum Size and Background Walls requirements need be met. See also: Housing Query Messages

Walls
An NPC room must have walls defining its boundaries, without any gaps. Solid blocks (Dirt Block, Wood, Stone Block, etc.) are generally required for these walls. Wooden Doors may be used to form parts of the side walls. Wood Platforms can be used for the side walls, ceiling and floor, so long as the NPC Block requirement is also met. NPC rooms are permitted to share common walls. If, however, you make both walls with doors in them, and the doors are open, you have to close the doors before the room is livable.

Minimum Size
An NPC room must meet certain minimum size requirements. The interior must be at least 8 blocks wide and 4 blocks tall (with 10x6 walls). It is also allowed to be 7 blocks wide and 5 blocks tall (with 9x7 walls). NPC rooms cannot be smaller than one of these sizes.

Background Walls
The interior of an NPC room must have background walls in the background. These background walls must be placed by the player, and cannot be background walls that were already there (generated at world creation time). Two known exceptions to this rule are the world-generated background walls within 1) the treasure room of a Floating Island, and 2) an Underground House.

An NPC room doesn't need to be perfectly filled with background walls. Small, window-like portions of the room are permitted to not have background walls, though players should be advised that the lack of background walls will allow monsters to spawn within the room. Player-placed dungeon background walls can be used, though they may allow dungeon monsters to spawn.

Light Source
An NPC room requires at least one placed light source in its interior. Note that many items give off Light, but do not count as light sources.

Flat Surface Item
An NPC room requires at least one placed flat surface item in its interior. The following are valid flat surface items for an NPC room:
 * Bathtub
 * Bookcase
 * Dresser
 * Piano
 * Wooden Table
 * Work Bench

Comfort Item
An NPC room requires at least one placed comfort item in its interior. The following are valid comfort items for an NPC room:
 * Bed
 * Bench
 * Throne
 * Toilet
 * Wooden Chair

Entrance
An NPC room requires at least one entrance. This entrance can be either a Wooden Door or a Wood Platform forming part of the walls. This requirement can still be met even if the player cannot physically enter the room through this entrance. Two NPC rooms are permitted to share a single entrance.

Corruption Limit

 * This is one of the more complex NPC housing requirements. All players are advised to pay special attention to this particular requirement.

An NPC room cannot have too much Corruption too close to it. A reasonable estimate is that no more than 49 corruption-type-blocks (Ebonstone Block, Ebonsand Block, Demonite Brick, corrupted grass, purple thorns, etc.) are permitted to be within a 42 block distance of the outer walls of the NPC room. This estimate may be slightly inaccurate, but it gives a rough idea of how much corruption is tolerable. It is technically possible to construct a small, suitable NPC house using walls of Ebonstone.

Note that the minimal distance required between an NPC room and the corruption is quite large, so players are strongly encouraged to be very aware of the surroundings near their house. Housing can easily fail to meet this requirement when corruption begins to spread in Hard Mode. This is especially true when it comes to underground housing, as it may be difficult or impossible to see the corruption underground. Additionally, the presence of Corruptors in hard mode can make it difficult to sustain suitable housing.

NPC Block

 * Most rooms meet this requirement naturally. However, players who wish to build an NPC room using wood platforms for the floor must be careful to meet this requirement.

The floor of an NPC room must have at least one solid block (i.e. not a wood platform), known as an NPC block, for the NPC to stand on at night. There must be at least 3 blocks of empty space above this NPC block (the ceiling must be 4+ blocks away). There must also be 2 blocks of horizontal distance between the NPC block and the side walls of the house (the left/right walls must both be 3+ blocks away)

Additionally, at least one Comfort Item or Flat Surface Item must be within 2 blocks of the NPC block. Furniture items cannot be placed on top of the NPC block itself though, as they prevent the NPC from standing there. Note: In an occupied house, the NPC block is the block over which the NPC's flag appears when the housing menu is open.

Update Info
1.1 1.0.6
 * Housing menu introduced.
 * NPC houses now require at least one Household item.

Bugs

 * As of patch 1.1.2, these bugs have not yet been fixed.


 * In some cases, assigning an NPC to a room will fail, yet the message "This housing is suitable." will appear. This bug is almost always due to a room that does not meet the NPC Block requirement.
 * Doors that open into a room take up space in the interior, potentially causing the room to not meet the Minimum Size requirement.
 * On my file my Druid, Wizard, and Goblin Tinkerer are living in the same house.  All their housing banners are stacked over each over.
