Coming to a housing estate near you, been on the go for a little while now but I do wonder about it. I would have thought a wider gap for insulation might be useful no doubt UK building companies will get into it once the profitability is proven compared to traditional build and the planning gets on board, that will be the tricky one. No doubt the next compensation disaster when the buildings start to break up after 10-15 years.
It must be economical and the planning people must approve because the display said that the Railway people were already using it.
Be interesting to see how it pans out, planning in Uk though is extremely tortuous even though methods have been used in the past. As for the damp, yes I could see this as being a possible issue if the cement remains cool and the house warm. Perhaps insulation on the i side walls may help, though I see the concrete being a good plan for warm climates. A thing I got involved with helping a chum with some work on a house in France was what he called ‘lightweight concrete’ this consisted of a mix that incorporated a high percentage of expanded polystyrene granuals. Think the stuff that breaks offf when you cut it, the individual bits. Whilst used for a floor on top of wood floor it made a good surface for tiling with good insulation properties. I could imagine this to be on the inside of a 3d printed house, itself with the lightweight stuff printed in place being a good possibility.
Down here they use polystyrene inside the concrete slabs they lay to keep the floor cool.
I lived in a house whose walls and floor were precast in the UK and shipped to Australia (was what married members were given by the RAAF).
