My musings on this so far:
Pros
They look nice
We've modernised the whole house (Victorian) so it would be nice to keep a bit of it traditional
The two bedrooms are for my Dd(11) and ds(10). At the moment they can accommodate a wardrobe, bed, chest of drawers and bedside cabinet easily at the moment as they are quite large rooms.
Kids don't spend that much time there just now though that likely to change in future
The kids like the fireplaces
It would save us money if we keep them as we don't have to fork out for builders.
Cons
They take up a useful wall in each room so can't put any furniture against it.
They will never, ever again be used as fireplaces as long as we live here so why keep them
Mitigating factors
Have to decide by next week as carpets and decorator coming
Do older kids actually spend time in their bedrooms these days? We only did because we grew up in a small house and it was the only place you could get peace/privacy
Could sell them if they come out intact and recoup the money
DH hates them
