I am planning on building a long, low profile outdoor cinder block fireplace with travertine veneer and fire bricks on the inside much like this one pictured here http://www.houzz.com/photos/28799/Urban-Earth-Design-modern-landscape-phoenix My question is, when it comes to the roof with the venting would it be best to build forms and pour concrete in place or is there a way that I could mortar in blocks in place for the final course? Many thanks!

Well I have been pondering this for some time and am thinking about the possibility of using steel studs with cement backerboard to bridge the top section. I just not sure if backerboard will be able to handle the heat although I have heard of people using it to line chimineys. Still open to better ideas though as this project will not start for a week. :thumbsup:
