Soil Vent Pipe Through Roof Near Window

Existing bathroom to be removed to make way for the stairs i have had some building control drawings done which show a new soil vent pipe up through the roof.

Soil vent pipe through roof near window.

This all being in my alleyway. This is the soil pipe vent part. Above roof plumbing vent diameter. It differs in name only.

He wants to have it come through the wall to the outside just above head height when standing in my alleyway and then up his wall on the outside up to the eaves. The main vent is stack is often but not always a continuation of the soil stack which is a 3 or 4 inch waste pipe that extends vertically down from the uppermost bathroom to the sewer. The window will definately be within 3m of the pipe but extending the soil pipe 900mm above the top of the window would obviously look obsurd. The reason for this is so than there are no foul or gas entering the house so that there are no illnesses occurring.

The pipe itself is exactly the same as are all of the fittings and joints. Is the vent pipe different from a normal soil pipe. I have a semi detached house and me and my neighbour share the soil pipe outside the council are doing some work on her house and left the soil pipe about 3 feet from the ground subsequently it has over flowed not very happy. The term vent pipe refers to the part of the soil system that is above the highest wet point on the system the highest point in which water can flow under normal circumstances.

What is the minimum requirement for a soil vent above the window or roof the minimum a soil pipe should be above an opening area is 100mm. All open vent pipes that extend through a roof shall be terminated at least number typically 6 inches mm above the roof except that where a roof is to be used for any purpose other than weather protection the vent extensions shall be run at least 7 feet 2134 mm above the roof. At the same time i am splitting an existing ground floor bedroom into two to make a new bathroom and cloakroom wetroom. In areas exposed to snow or freezing or temperatures below 0 degf that can block a plumbing vent the vent pipe should be at least 2 in diameter beginning at least one foot inside the building in an insulated space before the vent passes through the roof.

According to part h building regs the soil vent pipe needs to finish 900mm above any window within 3m of the pipe.
