My dad has a unit just like Sarah's. It was something he and my mum bought when they first married, almost 40 years ago!!! I hate it actually, the orange sort of wood. My dads house is a scrace style though and the furniture sits well in there, suits the house.
It doesn't go in Sarah's house at all. I actually really liked the look of the house when she moved in, really modern. And she did well to have all the things like shutters, kitchen island, decent flooring etc. If she wants older style furniture, she should have bought a period type property.
A shelving unit from Next would have fitted better in her front room, something plain and neutral. Just like Sarah
