Could anyone offer me some advice please? I am planning to have a further small extension built on the back of my kitchen extension (see photograph) to provide a utility room/downstairs toilet. The existing lean-to conservatory will be demolished as will the old back door extension (behind the green shed ). A new wall will be built to replace the current outer conservatory wall, the existing roof will be removed and a full width roof will replace it.
I would like to build a 2400 x 2200mm extension on the back of the house (for the utility room) from where where the kitchen window is now. Unfortunately (see other photos) there is a drain about 500mm from the existing back wall near enough under the current kitchen window. The main drain therein goes diagonally under the house with the flow going away from the house (still diagonally), under a boundary wall into next' door's garden where only a very short distance away there is another drain cover on their patio. The drain pipe is not very deep.
Given the location of the drains, should I give up on this idea and instead plan the utility extension on the conservatory side of the house (drain free). I understand that it may be difficult/ill advised to attempt to build over the existing drain? I should perhaps mention that the wall of the house (opposite side to the conservator) forms the boundary with my neighbour and that the conservatory is on the south side of the property hence my reason for not really wishing to have the further extension on that side.
Any advice very gratefully received. Many thanks.
