Having Wally and Beaver share a bedroom meant that their characters would always interact and add to the arc of the story.

Beav. PS I do know it's a set.

Ward was a little hard on the beaver.

An eighth child, Joseph, was a twin to Jim-Bob but died at birth.

They just changed set dressing as necessary.

but yes, both the Walton’s and the Cleaver’s parents bedrooms were shown.

My brother, who was 13 years older than me, would have thrown me out the window before sharing a room. I wonder more about why Sheldon Cooper had to share a room with his SISTER on "Young Sheldon."

Parents kept 3 bedrooms for themselves.

Bedroom
Exercise room
Yoga/ meditation room

All three boys had to share one small room

I hated it. He was a slob, and I'm a neatnik. But the shared room was dictated by circumstance. My Dad was a career Army officer, and even officers' housing isn't especially luxurious. We only ever had three bedrooms when I was a kid, my parents', my sister's, and ours. Once my Dad was promoted from Captain to Major, we qualified for better housing, and I finally got my own room.

Four rooms downstairs, but just two bedrooms and a shared bath upstairs.

I didn’t get my own room until we moved into our third (fourth if you count the apartment we lived in until the new home was built) house when I was 9.

two upstair bedrooms and a bath. It is a Cape Cod design or a Story and a half.

Unusual twist for our house.
We live on a corner, so the driveway comes off the side street & curves along a retaining wall into the basement.
So, we park under the house, which means we have a direct walk out to the backyard.
The rest of that floor is finished (utilities room, store room, laundry room, & rec room.
I guess we have 2 & 1/2 floors!

So, two-bedrooms kinda makes sense and they all shared a bathroom--no "on-suites" (can you imagine?)

I'm not sure it really mattered if you were upper middle class, with the exception that much nicer cars were driven...Once the 60s came, a lot of larger "ranch-style houses" or bigger two-story houses were popular--e.g., Bewitched...

guess it wasn't.

Sometimes Eddie would spend the night. Maybe they kept a room open for him so that Wally and Beav didn't have to listen to him all night!

but your point if valid

wouldn’t have been the same if they yelled across the hall to each other……

I wondered about that too and this is what I came up with. 😁

Ward Cleaver's occupation was never specified, but it was mentioned he'd been an engineer of some sort in the Seabees in WWII. So, he likely stuck with that after the war.

Anyway, if Wally and the Beaver hadn't shared a bedroom, all their pillow talk couldn't have happened. I'd imagine that's why it was written that way.

That would be an explanation. Or one of the rooms might have been a guest room. The study or sewing room could have been on the first floor.

Of course, the real explanation is that they didn't want to have to change the set every time they went into one of the bedrooms.
