Yesterday the guys from Wessex Water came over to check the Sewer Pipe that runs underneath the property and give their ok/opinion on it. Good news is that the Pipe are all fine , not cracked or broken , so we will be able to go ahead with building over the sewer. Bad news is : Our rear living room wall sits more or less exactly on top of the sewer pipe.(see Plans ) I dont want to change the size of the building and we cant move the building elsewhere , as the plot is too tight to move it significally. I was told that Wessex Water requests at least 500mm distance between any Piles and the sewer. So how do I support this back wall? I know I have to give this too my SE eventually to get it sorted, but unfortunately my SE does have the creativity of a Strawbale so every "creative" or "alternative" solution that was developed throughout the planning, I had to come up with and SE was just twisting the numbers to see if it works. On the other side , my Architect is VERY creative , and I could give it to him, but chances are that he comes up with a plan that involves a curved bridge over the property that is build out of carbon and supports the entire house via electric magnets , available for just under 9million £ (to be calculated by SE) My best Idea so far would be to build a kind of Foundation-Balcony Like this: Where the Piles sit back from the end wall for aprox. 600-700mm (giving the sewer the requested 500mm space) and the Concret RC BEAM just extends over the end of the piles to form this little "blacony" Fortunately, our house has a small flatroof, single story "extensions" on that end , so the weight on that overhang will be minimal. Any other , alternative solutions? Does this make sense or is it rubbish? And any other flaws in the drawings?
