Hi. If you paint the end ŵalls either a darker or warmer shade it will go some way to correcting the proportions of the room (Or if you like stripes you could add a striped rug or wallpaper). I must admit I would probably keep the chimney breast whether you change the fire or not, they add character and you can add consoles, cabinets, chairs etc which tend to look better in alcoves than flat ŵalls. I would also use a textured wallpaper in the long ŵall colour to add interest. I think the issue is the lack of furniture in the middle of the room which would make it feel wider. Could you add a coffee table? Is the sofa to scale in the 1st pic? I would pull it away from the ŵall even if it just inches (will help with radiator too, is that the only one you have in the room as it doesn't seem big enough?). I had a look in your Ideabook and it looks as if you want a windowseat? If so, i'd move the sofa so it's opposite the fire and put the armchair at the opposite end of the room and use a rug to define that seating area with the front feet of the seating on the rug. If you want the tv over the fire I'd put it on a tilting, swinging arm.

Thank you both of you! @Jen P: love the idea of looking at what Alys Fowler did. I just took a quick look at pictures of the show/garden and it's exactly the look I'd like to go with. I'll have to try and find a video recording of the show somewhere, as the YouTube link that's on the blog you mentioned does not work. I'll definitely be removing all the paint from the brick walls & repainting. Gravel is good too, but I am also toying with the idea of having decking everywhere instead of the current concrete. Water feature is a nice idea - it would add a relaxing element to the garden, especially in summer when we can sit outside on a Sunday morning to enjoy coffee and a good book! @Patrina: thank you for sending the picture. Interesting idea of splitting the garden into two paths, but I do not think mine is wide enough for that...

Most of the solutions for wetrooms require you to put a square tray on the joists and tile over it so it would be better to put it on the right hand side- lots of bathroom stores sell glass screens and you need to leave an entry gap of at least 50cm. Since this is a guest bathroom and used less often than your main bathroom perhaps it would be more cost effective to have a tray. If you do decide to create some boxing for a cistern I would put is on the left hand side rather than make the room narrower.

My experience for the distance between tv and point of watching is how big the tv is. You could also try and see what distance suits you. In my experience, you as a dweller create how you intend to use the space: watching tv / reading / entertaining / kids playing / guests sleeping / playing an instrument/ plants or a collection exposition / writing / paying bills / printer & IT hub... I am just brainstorming... In my case, I like to create piles: out of my books and magazines for projects, library books to return so separate from the many books we have, so I tend to welcome long shelves or tables. Sometimes it’s convenient to have separate dining and work tables - if you have space - because you can keep the surfaces dedicated for different activities. But again, it all depends on how you (want to) use the space.
