The best thing I did was line the block walls with larch planks from the local sawmill, looks a million dollars but cost less than any other cladding.
It was good fun to do, it’s a lovely material to work with, lots of benefits including, provides good insulation, prevents condensation and softens any noise.
My door is an insulated sectional with windows, my floor is ceramic tiles. The door was expensive but the tiles were only £5 m2 plus grout and adhesive, I laid them myself, again, that’s about as cheap as it’s possible to cover a concrete floor and yet, it looks very expensive.
