A player-owned house (often shortened to POH), can be bought from a Real Estate Agent, created, expanded, and upgraded by members. It is the result of a player's efforts in the Construction skill. Players can enter the house through POH portals, labelled on the world map as , located in 7 different places. Rimmington is the default house location, and a player's first house will always be there.
There are many different rooms that can be added to houses. The house a player buys will begin with a garden and parlour, but more rooms can be added. Different rooms require different Construction levels and will cost various amounts of money. Due to the Chaos Elemental's letters in Postie Pete's Postbag from the Hedge people think a bathroom may be coming soon.
The Crystal saw may not be used to boost creation of rooms. You can, however, use boosts from construction tea or a spicy stew to build a room higher then your Construction level.
A kitchen allows various levels of shelves, which contain unlimited kettles, teapots, gilded cups, beer glasses, cake tins, bowls, pie dishes, pots, and chef's hats. These allow you to make tea with the various other items in the kitchen which gives a temporary boost to construction. At level 67 Construction the best shelves can be made. You can also cook here if you wish, and re-building oak larders is a good method of training construction.
A Dining Room's most notable feature is the bell-pull (level 26), which allows you to summon your servant quickly. You can use the bell-pull directly, but it is quicker to use the "Call Servant" button in the housing menu under options.
The workshop allows you to build flat-pack furniture at your workbench, make clockwork toys at the clockmakers bench, repair barrows armour, and less significantly, paint steel and rune armour (this makes them nontradeable), and make banners.
Players who wish to hire a servant must have two bedrooms.
The Quest hall may contain an Amulet of Glory on the wall, which will give you unlimited teleports. This is useful for quick banking once you are finished in your house.
The costume room can be amazingly helpful in storing items that would normally be taking up room in the bank. Considering that all items in this room may be made flat-pack at a workbench, any player may have the best costume room.
The chapel may contain an altar, up to a gilded altar (requires 75 construction). In addition to being able to recharge prayer at this altar, players may also train prayer here, by using bones with the altar. With one marble incense burner lit, it gives 300% Prayer experience per bone. When both are lit, it gives 350% Prayer experience.
With a Portal Chamber a player can create portals with any teleports available to them, provided they have met the requirements.
The Achievement Gallery has several useful hotspots; the jewelry case, when fully upgraded, will provide unlimited teleports with the ring of dueling, games necklace, skilling necklace, combat bracelet, amulet of glory and ring of wealth. The Occult altar also allows the player to swap between the Ancient, Arceuus, LunarStandard spellbook without having to go to their respective areas (or have 99 Magic).
House room limit and sizes vary depending on your Construction level. At level 1, you are restricted to a 3x3 grid and 20 room limit, which gradually increases to a 8x8 grid at level 75 and 33 rooms at level 98.
Houses can only have a limit of one additional room above or below the ground floor. This means you cannot have a three floor house or have two levels underground.
Some rooms are limited to certain areas. For example, gardens can only be built on ground level, while dungeon rooms must be placed underground.
You cannot have a room above ground level if there is no room below it. If you wish to replace/remove a room supporting another room, the room in the upper level must be relocated or removed.
Costume rooms cannot be removed until all items placed inside have been taken out.
