Has anyone built these to completion? I could not really see the benefits, given that I can get an alchemy and an enchanting table inside the main hall, at least in Lakeview, so why should I waste two wings on them.
Is it just the view, or do you get any special items when it's completely built?
I have a save now where I have built the main hall for all three buildings and stored necessary building materials inside a barrel in each house. So now I'm ready to choose wings and complete the building process.

from videos, the alchemy tower may be nice for late game,
mostly because the large number of storage
which I use to 'mark' fancy potions (those with 2-3-4 effects !!!)
I basically store the special ingredients together as a reminder
and refill them from my main storage from time to time when supplies get low
basic storage:
common (under 10 gold)
uncomon (10-49 gold)
rare (50 gold and above)
then I go for core recipes
-fortify+restore health (wheat+blue flower)
I think I found a third effect/ingredient, but can't remember right now
-fortify enchenting (top secret, don't want to spoil your game)
-fortify smithing
etc etc ...
and the fancy recipe with slow, paralysis, invisibility
you want to remember the list of cheapest ingredients
wouldn't want to waste expensive ingredients on restore health, right ?
the enchanting tower seems nice to put relevant stuff together
basicaly the kit for small things that fit into pockets....
rings, necklace, diadem, even gloves
the idea is you switch thoses depending on what dragon you face
you could even carry arround a variety of hoods for magic
personaly,
first house = main house (bedrooms/armory/storage) (giant patio to look arround and keep family safe)
second house = alchemy lab (alchemy tower/greenhouse/kitchen)
third house = enchenting lab (enchanting tower/trophy room/library)
I like the enchanting tower, although I do not actually put an enchanting table in it. It has a large and small display case, 3 weapons racks, a weapon plaque and a mannequin, with plenty of storage space, a perfect little armory tower for a house without the armory wing. It has a shelving unit downstairs, but unfortunately it is full of the usual junk so useless.
magical staff storage ? 8D
too bad they don't have one handed wands, would be so cool
mmm .... two handed wand-wielding ... nasty ... !!!
