Dungeon Generator as Suburb Generator

I attempted to use my dungeon map generator to generate suburbs. Here are the rules:

• Room of any shape = building, doors = entrances (If no appropriate entrances, either plop a random entrance in - or roll a d4 for each side, 1 = entrance), roll d6 or number of storeys.
• Hallways = streets, doors = gates/arches.
• Stairs down = access to sewage system/underground.
• Stairs up = access to roof/higher levels of nearby building/landscape.
• Water = river/lakes.
• Anything else = point of interest.

Here is the generator:

And here is the end result:




I quite like it, now to convert the stocking table so it makes sense as buildings rather than rooms...
