They were the cheap form of housing built in their thousands across Dundee following the Second World War.
But 70 years on there are just a handful of original pre-fabricated homes left across the city.
The combined impact of war and lack of commercial high street activity meant there was a severe shortage of money and materials to cope with housing demand in the late 1940s.
It is now believed there could be fewer than 10 prefabs left in Dundee and the council doesn’t have any on its property list.
A research file provided by Friends of Dundee City Archives shows that some of the first were unveiled in the Barnhill area in July 1946.
Hundreds were subsequently built across the city, particularly in Ardler, Craigie and Downfield.
The Tele was able to find just four original prefabs on Harrison Avenue in Ardler and one tucked behind Downfield Police Station.
Many people have fond memories of growing up in the prefabs as they used to be heat traps during the summer, although during the winter conditions weren’t quite so enjoyable.
John Craig was just 27 when he moved into his prefab 49 years ago with his wife Ann on Harrison Avenue.
She passed away a couple of years ago, but John insists he couldn’t imagine moving into somewhere more modern now.
The former machine operator, now aged 76, said: “I have to admit it took me a while to get used to living here, but I’d never leave now.
“There actually used to be a another prefab alongside this one in what is now the garden, but it got knocked down, in fact there could possibly have been three.
“Most of it is made out of aluminium because it doesn’t rust and I paid 5000 for it in the 60s, but I thought that was a lot of money for the time.
“Some people might think there’s not a lot of room inside, but we raised three daughters here no problem.
“We actually have a loft too, although there’s only enough room to crawl in it.”
Also living on Harrison Avenue is Gertie Watt, 87, and her son Richard Watt, 66.
Gertie moved into her prefab around 1950 with husband James, who worked at Timex.
Gertie said: “One of the great things about living here is having a big garden, but like all prefabs it was freezing in the winter.
“We got a new roof put in, but it was an aluminium roof before.
“There used to be prefabs all down the street, but there’s hardly any left now.”
City archivist Iain Flett says folk in the city have fond memories of growing up in the prefabs.
He said: “They were originally built because they were cheap, affordable housing but people just fell in love with them.
“Most had running water with a bath, which was actually quite rare back then.
“They were built all across Dundee and their lifespan was 10 or 20 years, but they were there for at least 30 years and some for a lot longer.
“They were great in the summer as they were really warm, but during the winter they were freezing cold.
“People also liked them because they came with a lot of room. Most would have big front or back gardens.”
