My ever so considerate new neighbours are launching a new project to build a substantial summer house and the end of the garden, looking at it will be at least 2.x m tall and 7 meters wide. Given that I'm not really wanting to see this structure I'm considering planting some trees along the fence line, such as silhouettes with little spread. This would allow them to be planted closer to the fence (give or take 50cm). This seems like a reasonable approach and I'm interested to hear if anyone has had similar problems and which kind of variety they went with. I'm assuming 2-3m height would not be an issue, and I'm not going for Leylandii etc.
