What were temporary outside classrooms called?

There’s a specific name, not Canin/portacabin. I’m having one of those brain-melt moments and now can’t relax until I remember it. I know this is not of the greatest importance!

Prefabs

Huts or portakabins.

Portacabins

We called them Annex's at my school.

Huts

Huts for me (London, 1980s)
Mobiles for DS (West Yorks, now)

Terrapins for me. Even when they disappear over the summer and came back as a permanent building it was still called the terrapin.

I’ve never questioned why they were called that till this thread. So obvious it’s the company name.

Demountables, South Wales.

Huts.

Terrapins in 70s/80s Hampshire at primary. Mobiles in late 80s Hampshire at 6th form.

Huts

Terrapins at my school, 80s east England

Portacabins.

The huts.

Didn't have any at my school, but the "chicken sheds" have fairly recently been demolished at my children's school.

Mobiles

Cowsheds.

At my senior school all the 3 first year forms were in portacabins , known as ‘the huts’.

Yes we had a ROSLA block too,@zaphodbeeble I did know it was an acronym for raising of the school leaving age as my history teacher covered it ,but I thought it was just what my school called it ,but apparently dh school also had a ROSLA block too ,so it must have been a national acronym ?

Terrapins when I was in school (early 90's) but when I worked in a nursery recently they asked me to get something from the demountable...I was clueless! I'm in Wales

Pre-fabs at school in Yorkshire 1970/80's.

The Terrapin thing is a bit of a revelation - when the first person wrote it I thought it was a typo!

Terrapins. But I never knew why

Mobiles, although at my junior school in the 70s we had mobiles and Horsa huts (Hutting Operation for the Raising of the School-Leaving Age) which were from the 1940s.

Terrapin is the makers of them like portakabin

We had one that was called 'the pavilion'.
