Yes the trees can be removed or shifted if you wish, I personally moved them all up onto the hill behind the stable and barn and created myself a ‘hidden’ shrine to hircine within the trees

Your welcome just be careful with some houses, I think some houses may have some immoveable features. Always better to ask here about these things before committing to a purchase

Also word of warning about the overlook’s water area, there’s a Slaughterfish boundary before the large rock that sticks out so maybe advise people not to go swimming... or at least not to swim too far.... personally I built a wall around the safe area (yes I made the slaughterfish pay for it ) it’s a small area of water but it’s still nice and large enough for some creative ideas

Oh yea I suppose the fish boundary could be used for that.... I personally tend to leave corpses of my enemies hanging from the walls... I mean uh nothing there’s no hanging corpses in my castle.... definitely no torture room on the upper floor.... *closes the curtains on the upper floor*

But yea fear not, you can move/remove pretty much every thing that’s not part of one of the buildings in the overlook (except for the fountain, can’t do anything to the fountain except maybe cover it or put a statue in the centre or something)
