Just wondering if there are confirmed dates for your visit to the Guelph area, I'd like to go.
As we've discussed elsewhere my house is pretty cut up but there is 1 T-junction where the long kitchen/dining room meets the master bedroom and the living room. I'm wondering about cutting the walls out at the junction, putting in stud jacks or steel box beams to replace the removed supports and building a vertical RMH that overlaps all 3 spaces. This would permit it to be built to look more like a traditional fireplace in the living room. The wife isn't big on the "out of the box" way of doing things though I know she'd love the warm bench of a normal RMH since she is always cold. Too bad there isn't one to get her to try out nearby.
It can be done!
