Jen, are you sure everything is in proportion? I'm asking, because that store seems to be just a bit wider than a door (so about 1 m) which is fine, but doesn't give much space to manoeuvre inside it. Also, a bit too many doors in a small space, but I'm afraid I can't offer you a remedy for that. You have two wide, massive windows and a door in between, I think that will give plenty of light. Personally, I'd just add skylights or a glass roof. Or a long strip of glass all along What you don't seem to have is ventilation windows. Trust me, you're going to want one in the utility, or at least a good fan. Transom style windows could work too if you can open them. I really wish you'd see an architect... there are lots of different, small things that a professional can spot from miles away that you wouldn't even consider. As I said, I regret we didn't; our house is great, but it could've been even better!

I'd paint white the TV wall in oder to make it visually higher and to hide the white color of the door, now the dark color under lines that it is rather low and different from two main doors color and height of third one. I like brown FP wall, it works good with sofas and will attract eyes visually raising the ceiling above TV furniture. And one more thing I'd think about: the 1-st photo shows that there are too much unconnected different heights (doors, mirror, TV furniture, FP wall, ceiling). Definitely some heights are needed to be connected. I'd put lower the mirror and the shelf above FP so that the TV furniture and the mirror up lines were the same height. To bring more colors into the room as it was mentioned above I'd pick up some colors from the art work for cushions and curtains.

Thanks Decoenthusiaste! Yes that sofa is unavailable here and hard to find anything similar in local stores, but I may have one made up! So yes I’m using the images you post as inspiration and hope to find similar items here, I also love the grey Scandanavian sofa ideas you had earlier, and will use them as inspiration to get a lighter replacement. The blind on my window is screwed in place, but I could easily replace it with something that would let in more light, like the top down blinds (which are new to me!). I’m really glad no one has thought the absence of curtains an issue, as light is scarce here & I prefer the no curtains look. I do agree we should move the car to another part of our drive to get a nicer view out. A radiator cover that could double as a shelf would work well I think, I love the bespoke one, how cool! Also good to find out that you can get ones that allow the heat to rise. Re the music centre, I might replace with an iPod doc with speakers as Glo kindly suggested, In meantime I might cover it (and the dreaded TV!) with a piece of framed art leaning from the floor, aware that’ll be another competing focal point, but hopefully a nicer one! Thanks a lot for the tip re dimensions for a piece of art over the sofa and a coffee table, both of which are on my list to get, I would’ve had no clue re this and it’s fantastic to discover that there are certain rules which, if you apply them, can make your room work visually! Thanks again for the brilliant advice, I really appreciate it.

I think the sofa bed should double up as regular seating. The place is too small to have a guest bed around at all times. Use every item you have and if possible double functions (like stools as coffee tables and sofas as guest bed). Personal note: I used to have a 1p mattress with a cover on it next to my bed looking like a 'sideboard' (because my bed was sideways against the wall it wasn't a headboard). But 25m2 really was too small for any sofa to fit in. I just had one upholstered seat and guests would sit either on my bed or on a dining/folding chair. Another floorplan, with a sofa. I really like this one, because of the open living space. Some bottom-up blinds or a nice window foil halfway up should give some bedroom privacy, yet let in enough daylight (or a low cabinet/bookshelf, like in the second rendering). Add a bench in the 'bedroom' to enjoy a coffee in the morning sun. Bed sideways is not optimal, but it's give and take in a small home. Every open spot of floor adds to the sense of space.
