This extension has not been thought through at all. Chris’ plan of it in that drawing was way off, they clearly think it’s going to much bigger than it will be and are trying to cram an awful lot into it.
I think they’ve built it in a way that meant they avoided needing planning permission and in doing so haven’t actually had a proper architect do up plans for them, just their builder mate who has literally just said yeah I can stick an extra 6 feet on for you. A playroom in a kitchen? Are they crazy? How dangerous will that be! And the kitchen halfway into the dining space? Whyyyy? It’s going to look awful.
She really would have been so much better making either the existing lounge or office an actual playroom where at least they’d be safe.
