I've uploaded some pics of how it was before:

I am going to wait another couple of months to upload the after pics, because stuff is still pending like the bathrooms/kitchen etc.
The before pics make it look better than it was in reality, had to do a lot of redecorating, and things weren't that well looked after so new stuff basically everywhere. The good news is that the construction seems pretty solid, and everything is fine under the paintwork/wallpaper etc.
The only original things I'm keeping are the solid oak floor in the downstairs hallway, the shutters in the kitchen, and probably the long planter thing in the back garden because it would take a lot of effort to shift that.
I could live with it as it is today, but I figure I could be here for a while, may as well make it nicer to live in. Most of that budget is coming out of my new mortgage offer which is taking some of my equity out, but it's manageable.
