Brick? Rough hewn stone?
In my new [2 1/2 years since purchase] we made 2 intereir walls of brick, covering the origianl block.
* It gives a nice, warm New England - American - British look to the rooms [living room & master bedroom] & the walls. I find it quite pleasing.
* On 1 entire side of the house, exterior walls, we [ie Haitian stome masons] put an exterior wall / facade of rough hwen stone. Great fun! You go to a local quarry & sselect your own rough stnoes; then they are delivered. Much warmer looking that the original block.
* Note that I am speaking @ covering original, block walls. Neither the brick nor the stone walls in my home are load bearing. If you would like to have a leisureury look at these areas in my house[in POP], perhaps profiting from my poor taste or mistakes, please PM me.
* There are many rough hewn walls, etc. in POP, most of which I find attractive to beautirul. Load bearing? I don't think so, but you'll have to check. Good luck. A fun process!
