We intend to build an extension on our new house, just wondering what is the cheapest material for its construction per sq meter? Wood frame, block work?
Probably not the answer you looking for, but I think straw is meant to be very cheap.
cheap for material, or cheap for labour?
Cob is "dirt" cheap.
As is straw or old tyres and rammed earth.
They all take a lot more labour though.
cheapest standard building material, probably aerated 3.6N.mm2 blocks and a polish brickie. But then you need to add the cost of a render or cladding.
If I were to build a building from scratch though (I built my home as a conversion of a barn, so was limited with the fabric I could use) Id probably go for timber frame.
Cob or Straw bale and lime render by a long way.
lime render
costs a bloody fortune 🙂
Ice*
*electricity bill will be high keeping it frozen though.
Not if you buy the modern stuff. Our lime render bags worked out 20% more than sand/cement when I was selling them.
also depends on planning
😆
2skins block then sand cement render. However I wouldn't use standard render it'd have to be a monocouche render such as webber.
Time is an issue. If you have time to source second hand and used brick that can be quite cheap, people will even sometimes give them away (I got some from a wall though freecycle for a small project), but you have to clean them up yourself, which take more time again. You may have to give your self a year or two so to be able to accumulate enough / make contact e.t.c, but anything is possible.
Somebody else's ?
To include labour a timber kit clad with cement fibre board and a thin coat acrylic render would be the best option.
@wrightyson don't use that French weber stuff get on the K Rend, made in UK. Also do a lime render that is cheaper than cement render
I don't use any of it to be fair, plasterings not my bag to be fair and only wield a float at home.
However the lads used weber on a huge house I built a few years back and I was very impressed with the results.
Having worked for Weber for 7 years I can tell you that Weber renders are made in the UK!
Only messin. It's good stuff and never needs painted, just the odd clean down
It's good if the block work is built properly. Much better than acrylic but needs more skill and attention to apply.
Yeah had some bad staining on the external garden wall where the mortar joints from the copers above have leached, looks a real mess, any thoughts on the jolly green?

Indeed. I don't think I said it wasn't. 😀
Render won't stay clean if the coping is deficient. Could try cleaning with an algecide cleaner, but you need to pay attention to the coping for a permanent cure.
Actually Blind Melon you are correct. Weber renders are made all around the world including France. However material intended for the UK market is made in Telford.
Straw isn't as cheap as you first might expect since you need specially treated bales and you need to render or clad it - read about this a fair bit - still hankering after a straw mega shed!
No idea if its of any help, but coincidentally there are bricks for sale in the for sale forum!
