The resurfacing idea with poly paint is great, however I wanted to change the look of the doors, was planning on getting some hamptons/French country looking doors or shaker doors. Wanted to get rid of the flat no character look.

I’d suggest using pieces of plaster, painted in your chosen colours, to see what the colours look like in different rooms and at different times of the day. We were always going for Natural White which ended up having a pink tinge in certain light in our home. Our large back area is east facing (8m of glass stacking doors) with two south facing windows and two large skylights for northern light. Our colour consultant suggested Dulux Snowy Mountains Qtr strength and it is great for our home. Not stark (no blue/grey tinge) but definitely not too warm. We went all the same colour - walls, trims, ceilings - just in different finishes. Modern home with squareset ceilings. White is so hard. Good luck with your choice!

Try dulux snowy mountains. Just hope you plan to bring some colour and textured elements into space. With the tiled light floor, the effect might a bit cold.

These are my mock ups. Don't laugh. Online visualising tool are terrible. I think my roof and render will look much lighter than this. 1st is night sky. 2nd monument. I like monument better but once it fades i don't think it will look like this. I am planning a vine/creeper growing over the blade wall and maybe across the pitch.
