I don't like the way the builder situated the fireplace- I would like to relocate it to the right a few inches so that is is center on the wall. While I am at it, I would like to retile the fireplace, change the mantel, recess the area behind the tv. Basically I would like to go from the second picture to the first, A few questions I have are: what would this cost in material? Is this mdf? Where would I buy the material, HD has mdf sheets? and lastly how long would it take an average handyman with some carpentry experience to complete?
