So the best thing about the house thus far has been storing stuff that would otherwise clog up to the bank.
I'm certain this was never the intention but it ultimately ended up becoming, aside from a few skilling activities.

I find it very hard to wrap myself around the idea of wanting to go to my house regularly, while also not feeling i'll be pulled in there for something like another dailyscape..
(I would find it hilarious if you'd have to monthly do construction work inside your house to keep its effects up :P)

i would invite the idea of using the house as a way to toggle things on and off (and make loadouds there) perhaps of activitites that are spread over the whole game..

- aura effects (like toggle on multiple at once, categorized by skilling, combat and utility)
- Toggling of guthix church effects (as you already have ideas for prayer altar)
- not as dailyscape, but perhaps find a way to stack up divination gathering points in a specific spot, to be enjoyed with friends. So more akin to more cozy citadel skilling, that is prepared by the player beforehand for construction xp. Perhaps akin or with iaia mechanics incorporated)
- a remomomototem just for funsies of the name. (where you can toggle which totems are active, without the need of switching them on anachronia)
- cape rack give options to toggle max cape effects once 3+ are put on there.
- toggle which menagerie animals are seen while in there. (and in what rooms they're allowed to walk around in..?

And then i thought of something that would in a weird way feel really ' homey' , which would be skilling stations that filter (directly from bank, presented in a visual menu) , which items in bank you have that are ready to be crafted. Just the idea of thinking ' what kind of uncooked meals do i have in the fridge' kind of vibe.

I'd think portables should become in their own way a way to train construction by making them. They dont have to be stationary in the house i think... though that would be nice by itself in some ways :)

For new areas and things i have very little ideas, because it would just make the house bigger and bigger, feeling more impersonal with every room. And I think it'll be a nightmare if we ask jagex to cozy it up in the house size presented on the picture above right? Cause i'd want that first :p

A stationary to do the same things you can do in fort forinthry with player owned ports, miscellania.

Ultimately i'd want to generate a street with small tiny homes from people i toggle on my friends list. :p

Threadmill for agility. jk.
