A series of Housebuild commands allows players to construct their own homes. They don't need to be a house, they could be a garden, lake, temple, whatever they want; imagination's the limit... That and the number of rooms.
The first five rooms will cost 1,000 platinum coins each. After that, the price will go up 1,000 more for each further room (so, your 8th room will cost 4,000). For the other nuances on this feature please see the Player Homes Helpfile.
You have many selections of where to build your home from, there is a listing of HOMETOWNs for which you can set your recall (Teleport Home) point to at any time. Any of these hometown zones can have your house.
