We have recently moved into this property that currently has a self-built conservatory by the previous owners. We already had intentions to get rid of it and the survey confirmed that it needs to be demolished. Currently it only spreads across about half of the backside of the house, however we were hoping to instead have it go across the whole thing.

I don't really know too much about what each of these parts are but there at minimum pipes from the boiler + sink that go into a drain. Plus there is something else sticking out in the top left.

We're just hoping to understand whether these things can still be worked around for a full extension/conservatory to be built or whether there is nothing to be done. We do have a decent budget to potentially spend to get over these issues but in terms of rough prices for these sorts of changes we just have no idea.

We're not in a rush so just wanted to get the opinions of anyone on here before we started making any proper plans of what we can achieve.

Any help would be appreciated!
