Drain cover

[AudioDave]

Hi folks

I have this buchan trap in my garden, the area I want to monoblock.
I'd like to replace the concrete lid with something more aesthetically pleasing. But can't seem to find anything.
I know it needs to be vented etc.
The shaft size is 360x240 (inside measurements).
Could I corbel another layer of bricks to reduce the size and possibly fit a paving collar, or is there something that can go over the full area?

Thanks

Not something I’m familiar with or dealt with, but could you use something like this?https://www.plastics-express.co.uk/...h8yJ_MFldUDqeQtWzlmYjJYcsmStxghMaAtyREALw_wcB

the buchan trap isnt needed. you can dig own and cut it out of the sewer line completely.
