Build a home, build a community, build HOPE. Hope is a first person, world and community building roleplaying game. Set in the junkpunk world of EverSky, where people live on flying structures known as "rigs". Your role is to help build the community on a rig called "Hope", using a wide variety of tools. You will build, enhance and maintain the rig, whilst trading, crafting and socializing with the rigs inhabitants.

Very nice mods. You could implement a building "The Construction center" or something like that and in there you can access another building mode.
Not sure how successfull this is but I think it would be like "Hey I need a walkway here and a building there." and "I need to plan my Rig i need to go to the construction center and use the grid building."
Antoher Idea that just poped into my head. Some way to create a blueprint which helps position stuff in first person.
You can also add a delay of how long it takes to build, so instead of it just "popping up" you could have it so the building is built bit by bit.
