We are looking at have a single story extension done but its width across the back of the house is limited by a drain cover leading to 2 houses up stream of us (Our downpipe will be boxed in).
One comes straight in inline of the main drain, our next door neighbor comes in in the corner then ours.
I think its to close to our brick built shed (With large concrete base/foundations) to move that way but heard of double sealed covers for use indoors?
1: Can I use the double sealed cover inside the new extension (Floor will be tiled with a rug over the manhole) or does it need to be accessible 24 hours from outside?
2: can my extension foundations be built over the sewer pipe wit a lintel over the pipe itself so no weight on the pipe?
