Anyone know what this means on the title plans of house?

[user1471530109]

I've just been looking at a photo of the title plans for the house I've owned for about 3 years. I'm annoyed with myself as I've just replaced a fence that wasn't mine.

But there is a red line on the plans labelled with FWD. Any idea what this means as there is nothing physically there that I can see. Plan is from early 80s.

I'm no expert, but I'd guess foul water drain.

thank you. I googled it and got nothing. I couldn't work it out but that makes sense. The original bathrooms on both semis aren't at the back though? Which is odd? Or maybe not.

Parsley is right.

You don't need to worry about it unless you decide to extend at the rear of your house - you will then either need a build over agreement or will need to divert the drains.
