About 3 or 4 years ago my neighbours erected a 'chalet' at the bottom of their very long garden. I have a very small garden and from my kitchen window, my eye kept focussing on the new addition next door. I had hoped they might plant some greenery to help it blend in but they didn't take too kindly to that suggestion so it was up to me to find a solution.
I planted some fast growing shrubs. I couldn't afford to buy large ones and just hoped they would grow quickly.
I can hardly see the 'chalet' at all now. Happy days.
