I propose that we can upgrade our houses with decorations, larger storage, more crops even more rooms.
These decorations, storage, crops and more could be made through a new set of skills:
Construction.
With each level of construction opening up more and more items you can craft for your house.
With also 'sub skills' that specialize in making a specific set of items, ie: 'Storage Construction'
Anyone will be able to buy and use the items constructed by those with this skills and thus, expanding the Glitch economy even more.
New Rooms, or upgrading existing rooms, would only be able to be upgraded by the owner of the house and only if he has the supplies, energy and skill to do so.
Thank you for reading about my idea. =)
