Love the large timber post used as a feature.
Did you source the timber from Beauty Of Timber?
I also wish to incorporate some exposed structural timber posts in my build, just trying to figure out where to place them.
With the stepdown in the lounge area, do you have hydronic heating in that area?
What safety measures did you undertake to ensure that the hydronic pipes won't be punctured? It's fortunate that you don't have steel beams (like most double storey houses) that need to be bolted into the slab.
Also who is your window supplier?
