Plants or shelving are both great however an idea not mentioned yet very suitable could be a coat hanging area with a small table for house keys etc if you do not currently have that sort of area? This creates a foyer and is a good place for a quick chat with people you do not want to invite further into the house. Shelving would almost close the space and make the area smaller (visually) and plants may not be something you like. Good luck

the original ensuite configuration is excellent but this alternative provides 50cm extra storage wall in the wiw and a view of the vanity as you walk into the ensuite...i've also swopped the study and family bathroom to create the extra width for the entry and to keep all the plumbing (including downstairs) closer together and included an idea for the family bathroom that creates a multi person facility that is more private from the hallway btw moving the laundry downstairs removed the storage area for the garage so that lost space has been added back to the garage

You can make anything happen if you have enough money to throw at it.....so it always comes back to budget and requirements relationships. You can easily pull these walls out, and put supporting structure in - that's easy ....but will the extent of expense be sensible for your property???? If you want solutions that integrate structural remedial properly then you need to be working with a professional designer and aligned structural engineer. You can do supports pushed up into the ceiling, whatever you want, just it will be more expensive the more seamless& snazzy you want because you'll be pulling apart a whole lot of stuff and putting it back together. The issue with these little jobs that involve significant structural changes without achieving additional space is that you sink a lot of money into the building without adding the equivalent value.....there are always options, but Pro's will be best positioned to assist resolving the best balance that makes sense from both a function and cost point of view Hope this helps a bit Cheers PD:)

It would be such a shame to rip up your beautiful floors, to try and do polished concrete now would be such a hard and costly job, along with the mess and the uncertainty of getting a good job that you may not like on completion as suggested, why not embrace your floors, decorate with the industrial look that you love , maybe a brick or concrete look wall could look really stylish and cost a lot less in $’s and stress
