I'm inclined to agree with Jonathan but if you do want to go with the chimney concept and want a bit more variation to the 'shape' of the wall then there are a few things you could do. We've got an actual chimney breast and have put occasional bench seating either side with hidden storage below, which is super useful for times of year when we have extra visitors and need a few extra seats for bottoms! (Excuse the empty holes in the middle- waiting for our log delivery!) If you thought carefully about the actual chimney breast higher up I guess it depends on what you want above it- a large mirror or picture could easily be put up on top concealing a cupboard door behind it for hidden storage. Alternatively you could have the 'sides' of the chimney breast with hidden doors (push close / push open) to storage, so long as you think carefully about what height your shelves are at and avoid the doors opening into them. I always think books look quite nice in fireplaces, especially if you paint the inside a bold colour as a backdrop to them. I'm sure there are lots of other options too! Hope it helps! Claire

Looking at those photos of the built in furniture I'd be careful about overdoing it. Too many shelves and pigeon holes means filling them with someone or anything as space is a waste. I've a preference for freestanding furniture so it can be moved if needed.

My friend had a huge blank wall (no window) with a rubbishy, non original, fireplace, and she decided to buy a big shelving unit from Ikea and removed the fireplace. I was sceptical but it looks amazing and it houses her tv, books and ornaments. The room is decorated in soft grey and yellow and the unit is white so it doesn’t look too heavy. I haven’t got a picture of hers but it’s something like this ( first pic is Ikea).

Hi, I think it would be a real shame to rip those alcovers out. It looks like you have helpful storage in the bottom sections. Maybe consider some recessed lighting and shelves to make better use of the space or a large picture frame or mirror recessed towards the back with decor pieces in front.
