I enjoyed the remodeling and I hope that my design meets your expectations.
Regarding the fireplace, stone cladding is 5cm thick. The brick of the wall behind this layer is 12cm and the wall can be build according to the gas system. TV can be installed with an angle (10-15)o for an appropriate view.
Regarding to the furniture, the shelves can be ordered according to the dimensions as presented in the drawings. I think that the glass table would look good also in other forms but not rectangular.
I am at your service to provide any other information you consider relevant.
