Look at cladding your wall rather than just painting it. Metaline has some beautiful colours and could create this red wall look, but perhaps a better colour choice for you. I like the idea of a band of mirror wrapping it on all four sides, at some height of your liking. It would almost help dissolve the column and make the mirrored section disappear. If all that sounds scary, paint wide horizontal bands around it on all four sides, one stripe in a metallic finish paint, perhaps in a bronze etc teamed with a deep eggplant purple like one called double bass by dulux.

I have just turned a double internal garage into another room and turned the existing driveway into a courtyard. Swapped the drive to the other side of the front garden and built a Stratco pavillion as a carport. Best decision! Our garage had a 2.5m ceiling so it actually steps down from our hallway opening. I like the idea of integrating the laundry into a large pantry in the kitchen, will be doing the same next. original picture

brick wall so no option for cavity sliders gas heaters are already in that middle wall as marked, old heaters i think i need to service them as not sure when its serviced last also has two split aircons on both rooms on the far end no weather seals on entry doors, i can feel cold air is coming under some doors, where can i get the seals or is there someone who can come nd check all doors/windows and seal them tin flat room with not much space in between. I think there is insulation in the middle if not its very hard to do anything without opening up the roof sheets. We have double roller blinds on one side. No curtains on patio door(kitchen).
