It is hard to think of a pro.

A list of cons:
Shiny stairs + children with damp feet or flat-soled dress shoes = disaster
Ugly (fashionable) washbasin with immovable tap in a shiny-floored transit area = falls and broken bones
So far, this house is just dangerous.
Stairs whose lower edges are not rounded = scraped backs of heels.
Light fittings worthy of a hotel atrium. In fact this looks like a hotel, with the horrible institutional downlights and all the glass and metal and plaster. A hotel owned by someone who loves black white and ochre enough to cover thousands of square metres with them. And who hates every other colour.
‘Clever’ curved wall that means all furniture against it will have large gaps behind.
No privacy in the bathroom. The architect may find this unbelievable, but there ARE times human beings prefer to sit on and otherwise use the jacks without feeling like shop front window displays.
A bath that wastes megalitres of water.
A bathroom without a single storage facility, or so it appears.
A shiny floor in the dining room! + food and drinks = more broken bones.
A dingy, dark reading room/library with no place to sit unless you count that wide, hard wooden bench. It seemingly operates similarly to McDonalds, doing all possible to encourage outward traffic.
A relatively generous double doorway leading to a deck which is a thoroughly imprisoning space with its harsh concrete walls and oppressive cantilevered (‘clever’) overhang.

There is no limit to the coldness and brutality of this building. It seems to be comprised almost entirely of thinly disguised corridors.
And I’m presuming they’re planning to do something about covering the windows later- or don’t they mind looking like ants in an ant farm from outside?
