Don't envy you the cleaning you had to do! My sister-in-law's first house used to be owned by a chain smoker, we went round with my steam wallpaper stripper to do one of the bedrooms before she moved in, and the steam loosened the nicotine from the stairwell, it was running down the walls, totally gross.
At least you've got that out of the way, and can now focus on getting on with the garden. let me know how you do your raised beds, I'm debating whether to use old railway sleepers (expensive, but the beds would be wide enough to sit on, good as I'm disabled), old scaffolding boards, slightly cheaper but not wide enough to sit on, or bully the Husband into building me some raised beds with bricks.
You can always tell a true gardener, as they start to nibble away at the lawn to make the flower or veg beds bigger to accomodate more interesting things than grass.
I am very jealous of the size of your plot, though!
