Sooooo smart to take pics this way....people will never believe it! I go to car shows where they show what the cars looked like before they were fixed up after being in a field forever, and this is just like that. Your mouth just kind of drops open........

Oh wow. I had trouble even believing that was the same space - until i saw the window seat. Do you have even more rooms to share?

Do you have any furniture you are wanting to put in there ? Does any of it have any colour ? I like the light floor colour , the rest let's just say it is a good neutral base . I'd start with a new front door -- a darker varnished ( glossy ) wooden door , or possibly even a blue to reference your outside . Then add colour via furniture ( or at least cushions ) , rugs , and artwork . Again , maybe several different blues would tie in with the floor , but also the exterior . If there are only blue exterior highlights , you may want to go for warmer colour inside -- reds , yellows , oranges -- again , ties in with the floor . To this end , I can't understand why people go with 117 shades of grey and offwhite and wheat -- live a colourful life is my attitude , as long as it is themed haha !

Do you know what they are, they look a bit like Spotted Gum from the photo, whatever you do you will need a local professional to advise you on what can be done and achieved. Our Federation House had lovely old timber floors, I can't remember what they were but we found that having a more matt finish as opposed to a gloss like yours looked better.
