We are thinking of extending the back of our new (1950s) house. I'll rephrase that, the extension will happen, but I have a few basic questions.
Our adjoining neighbours have extended in a similar manner to what we want to. It will be a full width single storey extension with concrete floor to match existing. Projection will be about 2 metres, about 14sqm total. House is about 6-7m wide.
The biggest issue we may face is drains and water mains.
First water mains. The pair of semis is the middle of 3 in a row. But on the pavement is only one stoptap in line with the gap between two houses. Behind each house, against the wall is a stoptap/meter manhole. So I guess the water main runs parallel to the houses and all 6 run from the single stoptap on the street. Does this sound right? In which case is it permitted to relocate our water meter further along the main so it is alongside the extension and simply build over the pipe?
The drain. Again, this seems to run along the back of the 6 houses. Next doors extension appears to have a concrete lintel at ground level to span the drain. Does this sound right? The neighbours have told me they have a manhole in their downstairs loo (in the extension) but we would reloc the manhole alongside the extension with the water meter, as there are two gulleys along the back of the house for some reason, as well as the soil stack. All this will be moved for the extension so the only pipes under the extension will be an uninterrupted length of drain and the same of water main, though we dont know what this is made of yet. It enters the house as lead.
I'll knock up a diagram.
Cheers
