Many houses have disappointing layouts or areas of missed opportunities. For example, the Forsaken Stronghold has a massive foundation, but no basement area.
How about adding House Extensions that are basically portals to another house area you can only access from the portal.
Mechanics.
1. ) You buy a house extension the same way you would buy a house, but instead of getting a structure, you receive a piece of furniture that is a portal to the house extension.
2. ) When you access the ‘portal’ that may look like a door or a hatch or something like that, you load into a new ‘house’ area.
3. ) These areas would be completely enclosed to represent something like a basement, crypt, cave or cavern.
4. ) The house extension would then basically act like a ‘small’ home with the same features and ability.
