First ,is removing excess furniture an option? Second, why bar fridge in the dining area, that really ruins the look. Seems that you can not move dining table closer to the kitchen because you have light pendant above the table, so can you move piano where your black couch is and couch on the other side of the room instead of creamy colour sofa . I notice the luck of coffee tables and side tables,that's probably why you like to sit around dining table, it is not visitors friendly and doesn't encourage conversation or interaction. I will come back to it have to study photos more. Are the arm chain the other room similar colour to the couch in the dining area?

To be blunt -- the room isn't really big enough ! So you have to sort out priorities , and space . You have a dining table , and a computer desk . Can you get rid of the computer desk , by having your computer tower mounted behind the couch or similar , and a wireless keyboard and mouse that you can use on the dining table ? Mount the monitor on a wall , or if you don't need in depth graphics , I understand you can use your TV ( I've heard something about the 'refresh rate' is less on a TV ? ) . Maybe even have a monitor but also the option of using your TV ? Could you use a 'breakfast bar' , probably where the computer desk is now , I know its not sociable all staring at a wall , but it would/could serve as a brakfast bar and computer workstation . Could you get rid of the dining table and chairs , and have a large coffee table , or 2 smaller ones , and eat 'casually' ( my polite way of saying eat sitting on the couch ) ? Even mounting the TV on the wall will let you get rid of the cabinet , but I gather you have gaming consoles in there ? And the present arrangement with the pot plants uses some space -- maybe some shelves with them on will still retain the plants but free up floor space ? Just some thoughts off the top of my head .

Thats why I like my mobile home -- everything including 6 berths , kitchen , dining , shower , toilet , even a barbeque that slides out -- in 33 foot x 8 . Tiny homes are similar . If we really think about it , we don't really need much space in a bedroom -- imagine if we all had a bed that was say 3 foot in the air with a small ladder , and drawers and even our wardrobe ( with everything lying flat in a drawer or similar ) underneath -- you'd cut bedroom space by 2/3rds . Having said that , its still nice to have 5 bedrooms , each with an ensuite ; a formal lounge , a family room , a media room , a study , a living room , an office , a mud room , a foyer , an alfresco , a spa , a pool , a man cave , etc , etc .

Colour in photos can be tricky, but it appears your red timber floors are fighting with your brick and other timber items. Are they solid timber? Is sanding them back and staining, if their natural colour doesn’t appeal / complement, an option? Conversely, play to the red and grey scheme with lightly patterned grey / red / white or grey / navy / white curtains. Hang them high and a bit wider than the span to give a luxe look. And perhaps, if you go this way, finish your existing timber furniture in a grey wash or stain. Painting your brick is an option, as is cladding all or some in plaster or a simple panelling. I love the MCM chair you have in the playroom, and I’m a fan of mixing styles, but I’d replace it with a bucket chair or two in a different, to the curtains, but complementary colour patterned fabric. Once you’ve got your basics giving a more harmonious feel, start layering with artwork, throws, an ottoman or two, lighting etc. It takes time to develop a room / home. Don’t rush, chose your colour scheme and furnishing style and gradually move in that direction. Stick pretty much to the 70/20/10 rule and browse the Houzz lookbooks for inspiration, and importantly, trust yourself. After all, we all manage to dress ourselves without causing too many raised eyebrows, no reason we can’t transfer our good taste to our home 😉
