They didn't put the bedrooms in. The original listing in 2023 was for 4 bedrooms.
Look, spring is round the corner and you can sort the kerb appeal with pots and hanging baskets. Get some marigolds (the flowers, not the rubber gloves)
When you took out the hatch from the kitchen to living area (which was an ok thing to do), you seemed to lose sight of how an L-shaped lounge like that often gets used, i.e. dining by the hatch, sofas in the lounge. In other words, you need to break up that garage of a room a bit and make it look liveable.
Personally, I'd go to Ikea with a grand and see what I could do. I'd make sure I bought some curtains.
