Hi Everyone, We are getting on alright, photos are coming soon, pretty much done with destroying stuff and starting to build now. We have encountered a problem, during the heavy(er) rains we got some groundwater leaking in from the walls, 1 corner, 3 locations of the house. It seem like it leaks between the stoned, I am thinking just to raise the ground level a bit (the water just comes a few cm ups, and that all), then foil and 5-10 cm concrete on it. Any advise, better idea? I have considered: putting in pumps with barrels - do not want to run, service and rely on a pump digging down and putting in either plebes or pipes with holes to create path for water - it sounds like a lot of work an not sure if it would have a better affect than foil and concrete if we are just talking about a bit of water

Thank you, for free insulation, I have been told that I need to leave there for a minimum of 1 year. Scaffolding and removing slates sounds a bit extra work for now, but considered as an option. I was thinking to maybe use that area for storage but nothing more. I will put there ply wood floor, probably should insulate it before hand.

I am planning to remove all the floor boards and replace them, so I should be fine with space, but thank you for the advice.

Just managed to "model" the house, this is how the bottom floor looks like now:

As I just realised my loft has 0 insulation. I am wondering what do you think, which way (or any alternative) would the insulation would work the best: Green - Insulate the floor where there is no room and the sides of the room Red - insulate the roof The ceiling of the room will need to be insulated in both versions Loft photos:

So yeah, as I suggested, the walls are built the way like that, I do not know what that technique called. This is how I think I could insulate it: Questions: Do you think this is generally viable? On the photo below the nails are rusty, not sure if they require any treatment/replacement? 100mm PIR for wall, sounds good enough? Thickness suggestion for wallboard/plasterboard Thickness suggestions for wall vapour barrier? Update, These are the thickness for the regulation (0.3 Watts / m2K): EPS – 88.6mm thick Mineral Wool – 108.6mm thick PIR board – 65.7mm thick

Thanks @PeterStarck, I will do.

Arranged the design appointment when the measrung one, I will need to go in in about 10 days, will update on plans and prices then. Thank you. I will search for them, thought I give a general update and ask for any feedback

Realised some (probably) leak damage in one of the rooms, removed some of the horse hair plaster thingy and this is how the wall looks like behind it: There is no insulation at all, I hope there is a wood structure where I can put in some insulation, if there are not any I might need to build one, or go with alternative insulation methods like Lime plaster mixed with hemp directly to the granite wall. What do you guys think about this method, I got this suggested: Build a stud wall leaving an air gap between the external wall & any insulation. Use rigid rockwool batts, and finish off with a wood wool board

Got the keys today, hooray! I will upload plenty more images and plans on the existing and new posts. Today we just had the Kitchen furniture guys to come in and take some measurements (It was Wren kitchen, will see if we go with them or not, any feedback on them is appropriated) Structural engineer to come in and have a chat about wall removal Removed some floor boards to access the crawl space to take some photos Oh yeah and we found strawberries and raspberries (not ready yet) in the garden

So I should use 225mm if I want to go for 150mm, that might be an issue... I was even just looking at how poisonous/harmful the materials are and they said EPS is better. At the end it will come down on space and price I guess This is how the crawlspace looks like, sorry for the bad photos not really sure which angle would be the best for the crawls space, but it might give a bit of an insight:

I'm currently thinking to use EPS instead of PIR for floor insulation, is this a good or a bad idea?

It is about 30 cm, so not really, but I will remove all the floor joists, and put down new floor as ply wood, so I will be able to do what ever I want.

I should be able to post some photos of the crawls space next week, I am not sure if it would help in the decision or not. So right now, everyone agrees that I should install the vapour barrier on the bottom of the crawls space as well as below the UFH and screed? (sorry for keep repeating your answers, just want to make sure I understand it right)

@ProDave From the discussions from above, I pretty much draw the conclusion that there is essentially no point to put down vapour barrier if I insulate the floor and install UFH. What do you think? Correction: I am going to install the vapour barrier between the Ply wood and UFH.
