I was excited to get back and see what the new planting was like. What an immaculate garden. I would love to see it in a year's time when the plants have established themselves and shaped around the hard landscaping - and the greenhouse.
I think the painted guttering works really well on this one - it blends into the whole greenhouse and looks really chunky. The paint I use (Profilan Impra Opac) can be applied directly to plastics and metal without any primer just as it can to wood. It's the best paint I've ever found.
Please take a look at the video below for a short tour of this greenhouse.
