She's just full of tit, trying to keep herself relatable and failing.
It's a vicious circle with these instagrammers, they show every aspect of their daily lives to make money from it and be just like one of us, but then end up very wealthy, but still trying to make out they're not.
She could get away with it more easily in the old house, doing stuff herself (even though she could obviously afford to pay) because it was just a normalish house in a London/Essex street. Albeit expensive due to location, but it was still fairly relatable - in cheaper parts of the country a house like that might be within financial reach of many people. But now she's got the dream mansion with acres of land but has to try and maintain the facade of being just one of us, doing it on the cheap, to keep her followers onside, because without them the money dries up. At the same time she'll be getting as much free stuff as she can done for her (I bet she doesn't pay for the bloody kitchen, or not all of it).
One thing that I don't get is that I thought the house was listed? - is she allowed to put up walls etc internally where she likes, replace windows with full length doors etc? I thought in a listed building you had to get full permission for any changes to the fabric of the building? (I guess she may have applied for this already). Although I am confused about the listing, because I wouldn't have thought the conservatory would have been allowed to be tacked on to a listed property anyway!
