Easy to clean I suppose, and to keep looking tidy.
It's similar in every aspect of home design I think. We have a Victorian house in a Victorian street and each house is different - most have a nod to artisticness and colourful gardens, doors and paintwork.
There's one over the road that is as plain as you can get. It has flat, white blinds in all the windows, no decoration on the outside, a white door, grey marbley slate chip type things in the front 'garden' so it looks like a large square grave.
It's awful in one way as it looks so dead, but I can totally see why she does it - it's got to be easier to keep looking tidy than somewhere like ours which is all bits and pieces.
Part of me longs for that - but the bigger part of me appreciates beauty and colour and interestingness too much to actually do it.
Our new kitchen is very simple, and easy to clean, but it is colourful and interesting and lots of things on show as I don't like wall cabinets too much.
Trying to find a compromise I suppose.
