The Instant House Pocket Edition Mod for minecraft pocket edition gives you the ability to automatically spawn a bunch of buildings. The good thing about this mod is that it will help you quickly build some awesome minecraft maps, which you can then put up for download and let the community play with. But for this mod you will need an inventory editior mod which allows you to enter the ID of blocks. For example Too Many Items. This is just so you can type in the ID of the new instant house blocks / items.
