So, you build a beautiful house...

Mostly it’s smoke or burglar alarms (in Sims 2 or 3), and lights too.
Actually I just remembered something else… external wall coverings. But that’s probably because I’m not much of a builder (I’m not much of an interior designer or architect, and I always just want to start playing with the family so there’s impatience too) and I just think “as long as I’ve placed everything inside, I’m done”. I mostly play with the walls down, only putting them up for screenshots.

Well, I have never built a "beautiful house" since I'm completely hopeless at building but anyhow...
I don't think I have ever really forgotten anything essential but I constantly forget roofs and I also forget to remove them if I do changes to the layout, then have these nice floating roofs which I notice embarrassingly late.
I did have one intentional case in which I was running out of room to expand and was so lazy I just threw one of those pre-built rooms (or whatever you call them) in the basement and stuck their new baby in there lol. Then my vampire just teleported in and out when needed since nobody else in the family could do anything. Though later I actually bothered to build a staircase.

But seriously, I've forgotten things multiple times. Never anything quite as bad as forgetting a bathroom, but I've forgotten to give them stuff like a kitchen sink or an inside trash can. I kept wondering why they kept going outside to dump stuff in the trash, and then it hit me---DOH! lol

Oh, I did that once and failed to notice until after I made it a rental and had the couple 'move-in', as it were. Found out the hard way you can't go into build/buy mode in a rental while it's occupied …

You build the best house, in your opinion, that you've ever built. Its beautifully decorated, well laid out, comfy, cozy and you are certain your sims will thrive there. You hit the "Live Mode" button and discover.... You forgot to build a bathroom! How could I forget the bathroom? LOL

Its so sad and so funny at the same time. My sims are all standing around doing the peepee dance and I'm thinking, "just go to the..." "OH."

Have you ever forgotten something vitally important in your builds? If so, what was it? I'm curious if anyone else is super forgetful like me :p

Did this exact thing. I built a lovely 4 bedroom house that was in my estimation perfect. Until I realized there were no bathrooms. I almost cried.

So far I've never built a house from the ground up. But I have had problems like this a few times in houses from the gallery.

Either a given room is missing, so some critical item cannot be reached by sims - like a toilet or bed being blocked by clutter or placed in a room so small sim's can't use it.

There's quite a few high popularity builders that don't seem to test the things they upload.

And in editing a house, I have managed to do the same - wall off something and then not notice for a long time because it was in a house that was not 'active'. The neighbor of the sim in my profile image had a bed that could not be used - in a house I had rebuilt from an original download. I didn't know this for a month or two. Day before yesterday I had my sim visit her 'new neighbor' (that had been there for a while), and I tried to have them sit on the bed and talk and got that little Exclamation and feet bubble... Somehow a laundry basket was blocking the path.

Pool ladders, I never remember pool ladders. I tend to forget smoke detectors a lot as well... not that they prevent my Sim from catching on fire

Lord I'm continually forgetting lights! When I build now, I'll switch the sun/moon around to night to see if I'd forgotten any lights, lol.

Ok. For me, I often forget the thermostat/ smoke detector/ fire suppression system (though not much any more), attic gear (for decorations), the "outside" trash can (I've tested this and although the apartment trash chute works for trash, it doesn't count as an "outside trash can" on a non-apartment lot), but mainly having holes in the ceiling so lights don't come on.

Like @GalacticGal said, forgetting lights sometimes, but really the main issue I've found is a TINY hole in the ceiling somewhere. This "hole" in the ceiling, even if you have a roof over it, let's weather effects go inside also.

As for a castle toilet, it was generally like this:
:s :D

Of course there were the inside 'chute' kind also. ;)
