for me construction is like an endgame skill that you level up when basically everything is done and you just got a bunch of money lying around
so unless youre filthy rich already or get a billion gp an hour, construction feels like a waste, like that money could be used so much better
so its probably no surprise that my construction is my lowest skill at 40
i dont even have anything at my house, just a workshop used for a guest, i got all the exp from quests and tears of guthix
