I am planning to build a new house, but I have a question regarding a fireplace I want to have in my living room. I would like to know if it is possible to have the fireplace and chimney put up against a supporting/load bearing column? that is having the firebox and the chimney all the way up against the supporting column of the house. Is there any danger that heat will make the support column weak?
As always, consult your local building codes, but there shouldn't be an issue with heat on a reinforced concrete column. Whoever draws the plans will need to figure out an appropriate way to tie the column and the chimney together.
