    Hello we have bought an uninhabitable house on a slope and want to demolish and build ICF passive house, same size over basement ground roof bedrooms. TPOs on 3 trees at front, lots of trees in back garden and next to wooded area. Early stage, have architect, structural engineer is meeting us on site this week. My research takes me down many rabbit holes in the early hours and I have learnt lots already from this forum and hope to contribute once I have some knowledge. it’s nice being somewhere where someone won’t say “why don’t you just buy a house” - I may be thinking that in a years time but right now I am silly excited and little nervous about building our own house.

  1. Sorry I agree they should have worded clearer but my understanding is that it’s mandatory for licensed operator to provide documentation certifications that asbestos has been disposed of safely and not left at the side of a road. Lots of cowboys out there and licensed operators with documentation helps us all. You don’t say what kind of asbestos it is, some it’s perfectly fine to remove yourself while taking precautions others only license operators can remove but no matter what asbestos it was all need to be double bagged and tapped with care with full PPE. If they are licensed asbestos operator they should be still able to provide you with documentation certifications requested, so that element could be easily resolved if they were licensed to dispose of asbestos, although normally they are removed in asbestos’s skips after being double bagged and taped. The request for photos I know you can’t provide but maybe if you provide a risk and method statement of how it was removed that may go as far to satisfy them! For anyone out there reading this, best practice, No only practice, is to first get a survey to find out if indeed it is asbestos and what kind it is. If it’s a building being demolished a full survey by asbestos surveyor is advised. If you have a corrugated roof panel on a shed roof or garage or some artex you want to remove, you can get testing kits easily and cheaply on line where you send a sample to get tested and results emailed quickly some even provide PPE. My grandad died of asbestos related condition after installing in houses in the 60’s my dad is a licensed asbestos operator and removed from said houses 30 years later. For context, we were demolishing a 1960s house. We had an asbestos survey which advised we had asbestos panels in the kitchen and utility but it was the kind one can remove yourself and did not need a licensed person to remove. I wrote a method statement and risk assessment which you can also find on line, I did this for my own sanity but also to demonstrate to anyone who was interested ie local authority that we were taking full precautions for its removal. We had full PPE and took care and time to remove and double bag and tapped everything and then put into designated asbestos skip, as many have done here. During demolition we found corrugated sheeting in the garden and material under the fireplace that we suspected to be asbestos so we treated as asbestos as a precaution. We also got a testing kit for the board we found in the basement, test came back clear which made disposable easier. After skip was removed we got certificate to say where and when it was disposed which we forwarded onto the local authority.
  2. I can recommend Blundstone 192
  3. We had the waterproof system designed by a structural waterproofing specialist who was recommended by the ICF company. There are 3 types of waterproofing A, B and C. We need to have 2 types as I understand. Waterproofing outside the basement type A with membrane which also goes under the raft, geotex protection board and drain with backfill of washed gravel ( SE has been asked to guide us on what he wants in backfill) type B waterproof Concrete does not really work for ICF as you cannot see the end result without cutting away the ICF, our only option was Type C internal drain with membrane. This meets building reg standards in Scotland. The type C will hopefully never be used but it’s a fallback if anything does wrong. I know you could a number of years ago use 2 type As but that is not the case anymore. @saveasteading we are on a slope the back of the house is basement level and we have created a return on one side with a retaining wall. So a 2 sided basement not a cassette ie 4 sided basement. The internal drain is connected to outside drainage that then goes to pond and soakaway down my sloped garden. That’s the current plan. @Thorfun yes we have considered not having UFH in basement at all but as the main open wall in basement is north facing and we live in Scotland, thought better to put in during construction rather than regret it later even if we do not have it on all the time. @Conor I would agree but I’m being told that I’m required to provide 2 elements of the Type A B and C waterproofing system by building control.
  4. @Nickfromwales SE knows about it but has not said anything although I understand the mesh reinforcement will need to be bent but that did not come from him. He has had the proposed design for over a month and made no comment, shares office with architect who has drawn it up for warrant. We have asked about the bending of mesh and how he proposes this is to be done, still waiting. Maybe you’re right and I need to go for screed disappointed SE didn’t think to say anything before changing drawings, one step forward 2 steps back. Thank you for your comments, I really appreciate them. I will chase SE tomorrow, yet again the shared experience and wisdom on this site has trumped my well paid experts.
  5. @Nickfromwales our insulated raft is 250mm
  6. @NickfromwalesHead height but also I have 250mm of slab that can accommodate UFH, so screed on top seemed a wasted expense but I’m happy to be corrected. It would be easier as you can see from @Thorfun drawing
  7. Hi @Nickfromwales econekt, they are based not far from us and will be an assisted build
  8. This is our design WYK-SD 039 Stepoc Water and Gas Proofing with Preformed Channel.pdf
  9. @Thorfun we are building a basement open on 2 sides, construction ICF, intended to have UFH in slab only waterproof design has advised us to do in screed, we pushed back and they have given us a design that includes water guard drainage channel which we need to precast in the slab. I think you had the same issue but you went with a screed, is that correct? I saw one of the waterproof drawings and looks like they designed the same channel into the screed. Obviously easier than in the 250mm slab although currently this is what we are looking at doing and trying to get my head around how to actually do it, any pointers! for reference
  10. Hi @Kevan Marshall sorry I did not see your post sooner. I was in the same position bought an uninhabitable house Scotland although we are just outside Glasgow. No stamp duty although you find saving now you will definitely spend later, but the wee wins feels good. Although our solicitor told us to keep the monies that could be owed to one side incase HMRC question it later and keep photos of existing state of building and any surveys we do as evidence, I also had an email chain with planning who also deemed the house uninhabitable just incase. Know one’s come knocking yet, although I don’t have door just a big hole in the ground! Good luck to you
  11. The first photo shows the front south facing trees behind security fence, they have TPOs which is why the fence is there to protect them. The second shows the north back garden trees, which also hides a 45 degree slope of 9m which then goes down to a flat area of 10m, it then goes down another 45 degrees for 6m and then flat for 5m. Our farmer digger operator tracked a path for us for his digger and us after the photos were taken to the bottom of our hole, he also created a secret path behind the trees which leads to the flat garden but also able to access what will be the entrance to our basement. The skill of his digging and navigate his digger in and out the hole and moving the soil was amazing to watch.
  12. We have a similar issue when digging for basement, the house we demolished had a basement but was not deep enough and only used for garden storage. I did but didn’t really appreciate how tight our build is until it came to sloping the ground to accommodate the basement build. But we are in a slop, several slops in all directions, just to make things fun. we are heavy clay although we found some building sand had be used on the original fill in, which gave us some issues and had to dig wider to remove as this could have easily have fallen on us when working in our hole. We are still in our hole!
  13. You could carve it out of polystyrene or even foam depending how ridged you want it and then scrim with muslin and pva to give it a smooth surface and make it fire retardant, It could then be painted. It could also be done with paper mache covering a clay mould of the shape you are looking for. There are other theatrical prop materials that you can mould into shape that are easier to use than fibre glass, wonderflex comes in sheets and you use a heat gun to mould into shape over say a clay mould, can then be sanded and painted. Have you considered creating it in fabric and stuffing to create the desired shape, you could include a wire in the centre so it holds a shape. Check out Peter Evan Studios, they do vacuum form embellishments, it might give you some ideas https://www.peterevansstudios.co.uk/scenic-embellishment/ although I didn’t find a sunbeam.
  14. Not in Scotland unfortunately they stopped for new builds last August
  15. Oooo I want one, my garden consists of a 10m winding slope, fortunately at the moment I’m moving hardcore and bricks down to build a gabion wall to terrace said slope but if it was ever the other way round I would not cope. I’m at an age when anything I do that is hard and physical which currently is every day, I have a little voice in my head saying is this the way I’m going to go, face down slumped over my Whinny wheelbarrow head first in hardcore. I’m thinking a slide and zip wire to get down by slope in the future and a ski lift for the way up, maybe a track with remote control electric wheelbarrow is the thing I need, for me not the hardcore.
