Can I Change My Fence in a Shared Garden?

[gsthill92]

I bought my leasehold flat because it has a garden. Although the garden is shared, we all have our own little section which we all respect. The shared garden overlooks another street because the garden fence is so low, you can see right onto this street. On this street lives a very verbally abusive man who is none stop, and regularly brings his raging arguments out onto the street and it disrupts the area, the police are down there every other week and nothing seems to be getting resolved...My question is, seeing as I live in a leasehold flat with a shared garden, how possible is it for me to install higher fences to improve mine and my neighbors safety and privacy? Is this something I can ask of the landlord? I don't know of my neighbors contractual agreements and if they are the same as mine or not, so it’s hard to know what we are all entitled to, and if the low fence can be changed, who pays for it? If anyone can give any advice at all it would make my day.
