Construction

Construction is a members-only skill that allows players to build and customise their very own  player-owned house, or POH for short. Players design the house by arranging various square rooms and then filling them with furniture specific to the type of room, earning experience in the process. As players achieve higher levels, more types of rooms and better room features become available. Some rooms, such as the  Throne Room, are purely cosmetic and are for showing off wealth and achievements. Others, like the Chapel, are useful for skill training. Rooms can also be used to build a dungeon below the house, in which the player can engage in combat with friends. The  Portal Chamber allows players or any guest to teleport to designated locations without cost.

Construction is generally regarded as one of the most expensive skills to train. This is because the materials for building furniture have high prices, and there is no monetary payback when using them up for training. Skills such as  Prayer and  Herblore  can be more expensive, but they offer more useful rewards at high levels and the materials used for training can be produced by the player (killing monsters to get bones, using  Farming to get herbs, etc). The result is that more players choose to invest their money in these skills instead of construction. This skill is also one of the fastest skills to train depending on how much money a player is willing to spend.
