Is the building behind it a converted barn from what would have been the original farm? It's just odd the cottage front door is facing the back of the barn with no real route to get to it.
The particulars state it's secluded but with the barn right behind it, it really isn't. Especially being right next to a main road.
The house looks massive from outside but so cramped inside. I know you aren't buying the furniture, but it doesn't help with the feel of the place. There looks to be a lot of IKEA pieces which gives it a bit of a starter home feel, which it clearly isn't. Maybe they spent all their money on the build and didn't have enough to furnish it.
I do not like the bar in the hall, though having a grand piano by your front door is rather nice.
I don't like that there is a long walk to the bathroom from the three bedrooms in the old part of the house.
