I think the clutter isn't the issue, it is the things like the plastic doors, the vile bathroom, the built in furniture, the artexed WALLS, the wooden frame/pillars.
Depending on finances, it looks like a lovely house. But it's going to need so much stuff stripped out/off. I had similar in my current house, but my house is smaller so it was a smaller job.
Those grounds though. If you have the money, it could be stunning.
