I think it looks like a foreign persons idea of what a posh english house is like. The massive master bedroom suite on the ground floor gives this away as it is not normal in the UK for master to be on the ground floor and the kitchen area also looks very american. Actually the house looks like someone has made it in the SIMS video game!
They have just mashed together a lot of elements but are missing the air of history and that slightly worn look that big british houses have.
Way too much going on for me and the bits that are made to look 'old' just look souless as they dont have 100s of years of history absorbed into them.
its all just odd. I dont like the shiny grey minamilist look either but this is a bit too far in the other direction! There are some elements I like and obviously if someone gave me this house I'd bnite thier hand off as it is so big but it needs a lot of toning down!!
