Demolish boundary walls
1. glass pieces were scattered all over the place, inspite of knowing that glass cannot be disposed in the skip, or household garbage bin etc.
2. Worst part - glass pieces were mixed with garden soil, rubble and demolished leftovers. I've spent 4 hrs separating them. No rubbish-collectors willinng to pick them.
3. 8 large panels were left without breaking up - approx size 5 X 8 feet. None of these fit in the skip so I had to hire another rubbish collection to break to fit in the skip.
