One day I opened it and it was just a cutout of the floor, directly over the washing machine in the basement below. I'm not sure if that's lazy or genius, but it doesn't get much easier than that I guess.
Really it’s just a laundry chute. If the laundry room is directly under you, why make it fancier than that?
We have kids and a cat and none have had trouble with it. It's not half as dangerous as and has a lower attractive-nuisance factor than any set of stairs.
I remember crawling up and down it all the time as a kid while playing hide and seek or whatever. In fact it had a flaw of a weak latch. Sometimes when you closed the bathroom door, The laundry chute door would fall open, blocking the bathroom door from opening. When this happened the only way to resolve it is to send a small child up through the laundry chute to close its door.
That explains! I've wondered why people in movies/series would keep washing machines in the kitchen.
Around here in medium size houses like mine the washing machine is typically placed in the same room as one of the toilets and the room is referred to as the washing room (vaskerom).
Usually (flats/small houses aside) they'll be in the scullery (adjoining the kitchen) though, not actually in the 'cooking area'.
The only good solution which works is moving it to the garage, but it's not possible in every house unfortunately.
I'd never considered the child aspect, but that may explain why it had a lock on it(the turn up, push/pull, turn down kind, like on public restroom doors, unsure what they're called). Also, why it was so heavy. I wish I'd taken pics of it. From memory, it was probably 8"x8", about 2" thick. A small child could fit in it, but would probably have difficulty opening it.

If you want to something really "genius" look up razor blade wall banks.
And to be fair, this house was built in 1918, and I think part of the purpose was to have their maids/servants wash them. Out of sight and all. This house also had doors sectioning off the kitchen and made sure the basement had its own entrance.
He said a lot of developers don't want the expense that goes into building them. And a lot of owners don't want the maintenance expense. They get clogged up more often than most people realize.
That said, when I lived in Seattle last decade, my building was new and had a trash chute. It got clogged about once a month. You'd see the maintenance guys with big long poles trying to shove the stuff through.
A little of column A and a little of column B. Collectivism is sort of self-reinforcing, but there are also legal mechanisms that keep people honest.
The problem with those little hatches is that they create a breeding ground for rats and cockroaches.
They also serve as a fantastic means for idiots to grind your building's trash disposal system to a halt - when said idiots toss oversized items into them. (Christmas trees were a popular failure mode in my apartment building. How people got them into the trash chutes was beyond me.)
