My next door neighbor is building a diy conservatory.
Last week his father dug out the garden area. About 4m X 3m.
He only dug out about 6 inch's of soil across the whole area and filled it in with 1 ton of gravel and 1 ton of sand and then about 3 inch's of concrete across the top of it all. "Never even used a waker plate to compact it"
He's not building a wall, just using the frame full hight.
I'm quite sure he should have dug some sort of foundation for this.
Our garden's are quite boggy in the winter "so thats most of the time"
And quite dry and rock hard in the summer.
The wife's giving me a ear bashing saying what if it falls down and rips our back wall with it.
i told he we have house insurance for this sort of stuff.
I'm not at all bothered by him building this but it would have been common courtesy of him just to say he was.
