A knackered old 1950s bungalow near me has been demolished in the last
few days.

I went to look at the remains. Rendered block construction, and a large
pile of steel reinforcement rods ?

Was that a standard construction method back then for small houses, and
why ?

possibly "no fines" concrete?

I couldn't find anything specifically mentioning PRC and rendered block
at <https://en.wikipedia.org/wiki/Prefabs_in_the_United_Kingdom>, but I
suppose there could have been dwellings built of that sort.

Not bungalows and probably not within the definition of prefabs either,
but many council houses were built in the 1950s as "Cornish Units", with
the walls made of slabs (*big* panels) of reinforced concrete and
mansard roofs.

As they were sold under the RTB, the difficulty of mortgaging them
became a problem. The remedy seems to have been the support of the upper
floors with Acrow props and the replacement of the walls with brick.
There are some not too far from here.

does anyone remember "Bayko" - a children's building set at the time?
Steel roads and plastic panels. Must have been based on something real.

Having made a second visit, this might be it. The footprint left is only
the exterior walls, and huge chucks of concrete slabs piled up.
Mrs C reports two days of concrete 'smashing' noise last week. So a
suspended reinforced concrete floor ? The interior walls were block,
and presumably also contributing to supporting the roof structure, so
quite a load on it in total ?

We are seeing a few bungalows done like
that right now, not with mansard roofs tho.

Very common with new industrial buildings here.

Not a problem here.

Never seen that here.

BISF is steel frame and hardboard construction. There is usually a
(rendered) brick skin on the ground floor and steel sheet on the first
floor. Although many of them (eg the ones still in council hands) have been
upgraded over the years, with either brick facing or external wall
insulation. I don't believe blocks are involved. There were asbestos
cement roofing sheets which are relatively straightforward to replace if they
haven't already. Unless retrofitted there was no asbestos in the fabric -
simply a thin layer of insulation and then hardboard on top.

AFAIK there was exactly one design of BISF house, so if it doesn't look like
the ones in the pictures it isn't BISF.

They are actually comparatively spacious inside (1940s design standards) and
tend to be on decent sized plots so can be good value if the price is right.
They are in a sense on borrowed time as eventually the steel will rust, but
70 years on many are still OK.

"Selling can still be easy. If you’re short of time and you just want to
sell the property and move on, consider a “We buy any house” service like
ours. We aren't put off by these kinds of issues, and can buy your home from
you at a guaranteed price in as little as 2-3 weeks."

- of course they would say that. The 'guaranteed' price is likely rather low.
They're a semi, so rather hard to knock them down unless you're buying next
door too.

I looked at a one in roughly original condition - I love the 'tin' look, but
to make them fit for 21st century largely needs stripping out the hardboard
interior and rebuilding the insides with proper insulation. That was a bit
too big of a job for me.

Was it once a council house? Councils seemed to experiment a great deal.

Those houses must have been freezing in cold weather. Zero
insulation.

Now I would expect to one one the right to be studded out on the inside
and insulation packed into the void.

It's a while since I worked on that street.

They are (or more usually, were) equipped with a very robust dry wall
liner with a fair sized air gap.
