Hello everyone,

gradually more insights are emerging regarding our purchased plot on the hillside. We are planning a normal gable roof house on the hillside with a north/south orientation together with an architect. The street is located to the north. It has now become known that the channel for discharging rainwater is positioned higher, so we end up with the downpipes on the south side. Unfortunately, due to the eaves heights in the building area, it is very difficult to rotate the roof to east/west because you then have to maintain an eaves height of 3m. With north/south, we have 6m and 3m respectively towards the street.

Now my actual concern/problem. Currently, we have no reasonable idea how to drain the south roof. A cistern plus soakaway is not permitted; according to the soil report, nothing may infiltrate into the ground.

What do you think about placing the two downpipes (east/west since a dormer on the south is planned due to the eaves height) on the wall and cladding the house with HPL laminate/Trespa panels to conceal the pipes? Are there other ideas on how to solve the problem? We would prefer not to pump the rainwater uphill; this has been advised against from all sides.

I am grateful for any advice!

Micha

Hello, can you show a plan including the sewer pipe depth, section, with dimensions from the narrow side of the house, that is where your North + South rainwater downpipe is planned?
