High border and gap in fence

Itoohaveagarden_21

Hello! 

Having a brain fart and can’t figure out how to word my issue in a googleable way!
I have plans to make a high border next to my fence (ie brick wall a few bricks high and then fill with soil) but I don’t think my neighbour would be too chuffed with 30-50cm worth of soil falling through the gaps of the joining fence!
should I use plastic sheeting? Will that look rubbish from their side? If I use wood will it eventually rot?

Also how wildlife friendly is it me having a tall border my side and him potentially a ground level one on his side? I’m imaging a little hedgehog sky diving catastrophe!

the reasoning behind putting in a tall border is that I’m in a new build and the quality of the soil is obviously abysmal so planning a no dig style.

thank you!

You could build a completely enclosed raised bed, then the soil can't fall out.

What is the fence like? How is it constructed? A photo would help if you can 
Heavy duty plastic - pond liner is ideal - attached to the fence would do the job, but if you're concerned about the neighbour's view, you could use a couple of scaffold boards or similar, attached first. 
It's a small raised bed you're creating, and yes - a great solution in difficult ground. I do it in every garden 

I wouldn't worry about the hedgehogs if they have other areas to get in and out

If you could post a photo of the area that would help. If l understand you correctly you want to use the existing fence as the back of your raised bed in spite of the existing gap, but l think you'd be better off constructing a complete 4 sided bed.
As long as the hedgehogs still have at least one route in and out that will be fine 🦔.

So here is a mildly aerial view and it would be the left side fence

Yeh - not very hospitable is it! 
New builds are always a problem re soil and it's condition. I'd go for your brick wall if that's what you wish, and then just do as I suggested.
Ideally, you'd have the beds made of brick all the way round, but that's obviously a dearer option, so it depends on your budget.

Yeah it’s pretty bad! Currently not got any wildlife let alone hedgehogs 😂 that’s definitely a future problem! 
the cat gets incredibly bored sitting on the mud so can’t wait to get some stuff in!

thanks for your help as always!
