As I mentioned in my first post, I will split the tasks which I need to work on. I hope I am posting at the most relevant location, this post would be about insulation of a granite house walls internally. I have been advised that granite houses should not be insulated directly on the granite, it needs to have a cavity so the granite can breath and dry. I am wondering what would be the best way to insulate the walls internally while they still keep their breathibility. I come across a product which called Bauwer light, anyone used this before, reviews does not seems to be incredibly conclusive? Would it worth to go for that type of insulation?

Not sure how much would it help but there could eb a possibility to install L brackets and use 150mm insulation boards like that: What do you think? Not sure how beneficial it would be.

It seems that my post about the crawl space should have included the joists, floor and the UFH as well in it, as it seems to be all connected. I have put some more information about the planned changes to the floor an insulation in that post.

Hi Ferdinand Thank you for the idea, now sure how to do that yet, but I will have a look around. Thank you again for your detailed overview. I think I might not be splitting up the topics right, so I should include info about the joists, floor replacement and the underfloor heating. Current understanding and my plans: I was planning to put the heavy gauge vapor barrier on the crawl space, which is in your description should not require. I will replace or marry up the floor joists depending on their status When replacing the joists at the external end, I will protect them with some foil for extra water resistance My joists are about 50x130mm so I should be able to use 100mm celotex (or any brand) insulation boards. Drawing: Replace floor boards with 18mm plywood Install heave gauge vapor barrier on the plywood floor Install UFH Porcelain tiles and laminate floor on top of the UFH If I understood correctly, you think this probably will not be enough for an efficient insulation for UFH. I did not detail the materials yet, as I wanted to make sure I have the process right first. Does it work looking into filling up the entire crawl space as your options 2? My crawl space is just soil, does it require any other preparation? Good point about the doors, I have been warmed about that.

Good point in my other post, I will just add extra replies here, instead of keep changing the original and make it confusing. Made 2 topics, and will create the rest:

Thank you, good point. I will just add the links, but I will not edit anything else on it. And I guess I will create a post in my "main" post when I created a new topic Some of the floor joists, seem to suffer from wet rot and there are some signs of wood worm. I would upload photos, but I did not take any when I went in last time and my official move in date is on the 03/07/2018. I am trying to be as prepared before hand as possible. There are vents, not sure how many and how big they are, should be able to update in a week. It even seemed that one of the vents is inside the living room, I assume it is for the wall cavitiy and/or crawl space I will remove the radiators and want to have the under floor heating as the only source of heating (maybe fireplace, but I still would rather change those as they are gas ones). I was going to go for Schlüter-BEKOTEC, I will create a post about that one as well, including all the other floor issues (or should I keep it in here as one?) Well, I am trying to protect my floor joists, as I said I am not sure if I even need the barrier there, but as I will remove all the floor boards, it would be the best time to install.

As I mentioned in my first post, I will split the tasks which I need to work on. I hope I am posting at the most relevant location, this post would be about the removal of a (possibly) load load bearing wall between the kitchen and the living room. The only problem which I can see is the fact that half of my staircase is connected to the wall. I planning to refurbish the staircase as well, but I might keep the same frame. I booked a structural engineer to come out and have a look, they said it will cost £450 + VAT, I assume they will advise on the size of cross beam I will need to use and maybe supply some drawings. Managed to spoke with my local council, they advised that as it should cost less than £5000, they can turn around their decision in about 1 week, and their fee would cost pretty much the same as the structural engineer's. This is a rough plan of my house, the L shape next to the red marked wall is the stair case: I do not really have any questions here, of course any comment is welcomed, I am just sharing my current findings.

It looks nice, well done! A first stage "development" I am focusing on the internals. I was thinking to extend upstairs as well, but right now it will be just OK for size. The only "thing" which I might add is an extra walk in bit before the front door, something like that: Probably change it's roof for a pyramid style so the guttering is sorted.

As I mentioned in my first post, I will split the tasks which I need to work on. I hope I am posting at the most relevant location, this post would be about the "insulation" of a granite house crawl space. The crawl space is about 30 cm deep. I have been advised to install/lay a heave gauge vapour barrier and put sand on it as an extra protection against vapour (joist wet root). When I started to read up on it, I came across a few different solutions: heave gauge vapour barrier (just on the ground) and put sand on it From my readings: it could create puddles, as water could leak from the side walls heave gauge vapour barrier on the joists From my readings: bad idea could just collect water and pretty much continuously soak the joists in it heave gauge vapour barrier on the walls as well From my readings: it might require a pump and/or guttering system heave gauge vapour barrier on the walls, block the air vents, install dehumidifier and sensors I do not know how would that work with granite house and cavity walls, it might will depend on the wall insulation which I am still looking into it, but that's an other topic What would be the best way top lay down the heavy gauge vapour barrier, do I even need one? Please let me know if you need any other information and if I can answer, I will upgrade the original post.

No, initially it is for vapour/steam protection. I have been advised to install it to protect the floor joists, but when I looked in to, I am not sure if there is any point, and if there is then how far should I go up, do I even need to block the vents (I do not think that's a good idea) etc. Yeah they are pretty much together you are right, there are some separate topics with each, this is why I split them. I should be able to fit 100mm thick insulation boards Yeah, I see your points, I am just not sure how to actually insulate it, as I assume I need to keep them breathing. I found a brand/product, but not sure if it is actually as efficient as they say. Tried to read some reviews but most of them seems like written by people who making/selling it. I am talking about Bauwer. Anyway, I will make separate posts, and update my original one with the links

Hi, Yes, Aberdeen it is. Of course, I'll try to post some photos, I thought it would be better to post for the specific threads.

Dear All, Thank you for accepting my registration. Please see below the overview of my current "DIY" project: I have recently purchased a granite house in Scotland, and it does require quite a bit of a refurbishment. After reading more and more on forums and watching videos I ended up with more and more questions. I registered and posting for 2 reasons: To find the best way to solve these issues and Hopefully help for people who face similar problems/questions The main reason why I am not sure in some subjects like wall insulation is cause there are many different opinions and/or not enough information on granite houses (at least I either did not find the right sources or it did confuse me). I am looking to do the following refurbishments which of course I will post in the relevant forum threads in more details: Wall removal – 1 load bearing 1 divider Installation of heavy gauge vapour barrier to the crawls space – quite a few questions here Treating and fixing floor joists – should be relatively straight forward Insulating floor and replacing floor boards – should be relatively straight forward Refurbishing staircase – will see how complicated it will be after a more comprehensive inspection, maybe use existing frame Installing insulation on the walls – not sure if required Installing underfloor heating – should be relatively straight forward General cosmetics (wallpaper removal, painting etc.) From these points some are straight forward, some I am not even sure if required. I would like to document the whole process post photos, videos, prices and time to help for people who are trying to do similar projects. I am planning to hire someone or a company who can do help me in some of the processes and probably give me advice on stages which I will try to do myself. I was already looking through some posts as a guest, and although I still have many questions, I am 100% sure that people here will be able to help me out. Every feed back is welcomed, thank you in advance, Daniel Some photos uploaded as requested, nothing exciting yet:
