Strawbale building: We built a straw bale home and concluded that straw bale buildings and thermal mass heaters work really well together. This site provides a good introduction to strawbale building and has lots of useful links.
Fire tools: We had our fire tools made by a local blacksmith (Galba Forge). Philippe did a great job and better quality than I have seen in a shop. The added benefit was that they were made to the length we wanted. We also had some other blacksmithing done for the house and it was great.
