The Creel Cottage.

Based on some of the earliest homes, the Creel Cottage just consists of a standalone Common Room. It has a small fire pit, and area given over to storage and an area given over to living, and is surprisingly effective. On a larger scale, it was the Saxon Longhouse type dwelling, the basis of many croft and hall houses, and leaves plenty of scope for development. We know that Unskilled Commoners sleep on 'Tavern Floors' from their Cost of Living description. I have extrapolated that to assume they can sleep on any common room floor. However, for the sake of game balance, I have set the number at 5x people sleeping in a common room.

Workers Cottages

Based very loosely on the various small workers cottages that I have seen around the UK, modified slightly for the PF Rules. In this case, a lodging and a garden make two small cottages that can each house 5x commoners. The slightly better living accommodation means that one (or more) of them might have a single point in a Craft or Professional skill.
