Yes we had balling in our mixes and I was from a “who’s the thirstiest” battle between lime and shiv. We did dry mixes and then added water. This started the fight lol. I’ve seen you adopt water/lime slurry method and added that to the shiv. I’ve seen this in Canadian hempcrete mixes so looking like that’s the future 🎉
Ahh, we thought we came up with that idea ourselves 😜 We only decided to do it that way because, we were mixing inside and know how dusty the lime is. We did also mix the lime and water first, in the bell nixer, when we did the external walls.
Really interesting approach. Smart problem solving too, you need to name that technique! Absolutely lovely textured finish, looking forward to seeing the finished colour. One question, will you be able to hang pictures n stuff? Would you need special fixings or long screws into a stud?
Cheers. For something light, like a picture, we'll just drill a small hole and put a rawlplug in with 50mm screw (hole smaller than rawlplug) for anything heavy or taking weight we could use long fixings to reach to studs which are at 400mm centres
Firstly, really great video and series on this interesting project - something I'm in fact considering now in NZ so cheers! I was wondering what the rain penetration on the lime rendered walls will be like? Its great that you can apparently do away with a cavity between cladding and wall structure but with eaves that look only about 400 - 500 mm wide do you have any concerns with direct rain on the walls?
Hi, thanks, glad you're enjoying the series. As long as you use a natural, breathable paint on the render, it should last anywhere from 20 - 30 years. We have plenty of 500 year old buildings, that use lime and are still standing so that's a good sign :-) The eaves on this house aren't very big, although bigger than what most get in this country. They are about 350mm. The house is very exposed and so gets a lot of driving rain but it seems to be surviving the winter pretty well. One added bonus of lime render is that it heals itself of cracks. The lime underneath hasn't fully carbonated and if cracks appear, rain will actually help seal them back up. We have discovered something interesting with some test boards we did and will chat about that in the next AMA episode. Thanks again for the views. Cheers.
hi matt did you have many problems with building control with this method of construction . can you give a rough cost to build the house please. where did you get advice and have you been on any workshops before embarked on this project .
Hi, I'm not Matt, but I have been on the whole build with him. He's not got an accurate figure yet, but the build is roughly £200k including the land. He will be working out properly in time for our next AMA episode though. Building control were ok with the supporting wall and just wanted the structural engineer to give it the ok. At the beginning, Matt had to ask a few companies that were willing to let him work with hemp but he managed to find one that had done it before and were comfortable with us using it. We didn't do any workshops as they are few and far between but we both have a copy of The Hempcrete book, by William Stanwix and Alex Sparrow which is very useful. On top of that RUclips University is a big help too. Matt is a general builder, so other than the hemp, he had pretty much done it all before, just on smaller scales. This is his 1st full house build
@@thelowcarbonproject how did you manage to fund the project , is there a company willing to lend on such a project ? is it easy resell such a self build . and would someone get a mortgage if they wanted to buy .
@user-js9cy9tz8t Matt is a very good saver so self funded it. I know there are self build mortgages available. There are plots of land for sale, specifically for self builders that offer finance. There are also "green" mortgages if necessary to buy a house like this, Eco. We know lenders are risk averse at times, but he doesn't intend to sell anytime soon. It's better than new builds, and fortunately, we have this channel to prove it. We will be gathering a lot of data over the next year to prove how well hemp houses perform. Everything from energy efficiency to air quality. We will need to get an EPC certificate. It will be interesting to see those results
Morning Matt, I have watched all your videos and I am impressed at the build quality and the construction method/materials used. Your architect has engineered the design very well. I want to do a 2 storey rear extension and loft conversion using hemp and wondered if you could possibly tell me who you used for your plans? Kind regards, Julian
Hi Julian, I'm Phil, I run the channel and you've probably seen me buzzing about in all the videos, cheers for watching 🍻 If you drop me an email to thelcpchannel@gmail.com I can give you the details you're after, don't want to post others emails here.
But why? Why insulate with hemprete an interior pillar when no insulation is needed for interior pillars? The city basically didn't care about the hemp they wanted every inch of the wood covered with fire retardant board. Using simpler insulation for interior walls would have saved so much construction time. Straw bail, wool, wool panels, expanded cork. Cheers
Why not? We basically had left over hemp and Matt wanted to try for a feature wall of hempcrete downstairs. It's just an experiment really. Like he says, if he doesn't like it he can just cover with lime plaster. He is trying to avoid wool as we have heard from an architect friend, that they had big problems with moths, expanded cork is expensive and a straw bail supporting wall would be too thick.

@@thelowcarbonproject Morning Phil, sorry about that. Thank you, I will send you an email. Great work and very helpful!
what lime did you you please?
Hi, we used this product www.celticsustainables.co.uk/lime-green-hempcrete-binder-for-hand-casting/
Oooh, jolly useful, thats for this, and the channel! Roll on my hempcrete garden office this summer :-) @@thelowcarbonproject
@GriffinHistorical Niiice, keep us updated on your progress, maybe we can come visit for an episode 😀

Wow that accent is not easy .....
@tabiripetrovich517 Ha yeah sorry we have been a bit slack with other language subtitles, we will get on it. What's you native language?
