I'm helping my friend redesign the yard for a house he just bought. His house is on the right hand side of this pic. In between his and the neighbour's house is a huge shrub... or rather, two huge shrubs that have melded together as one. If I could have it my way I would just rip out the whole thing and start anew with something that would let in more filtered sunlight rather than casting heavy shade on my friend's house. I also dislike how it makes the house seem even tinier than it already is. But removal I'm sure would be pricey, not to mention we haven't consulted the neighbour yet. My friend would be open to trimming back his side of the shrub. So I am wondering how much of the shrub is it safe to prune back without the whole thing dying, or without exposing the more sensitive inner part of the shrub to the elements, which could cause browning needles/leaves or parts of it dying? Also, would it be possible to take out the whole darker coloured shrub on the right and leave the lighter coloured one on the left, or would that look ugly since they are fused? Thanks!! Here's another shot of it, from the neighbour's side. It looks a bit nicer from their side; my guess is that they'd probably want to keep it like that.
