  1. After some snow and heavy rain, I can see my design in action, physics doing what physics does. This is the 1st pond that has now overflowed with run off. This level has raised about 400mm. Although not finished. This has now overflowed into a gulley / pipe, that when it's finished will be concreted and form a better overflow outlet. The last pic is the new pond and the darker green shade in the water is the overflow water entering the pond. The new pond rose around 150mm so around 1500l.
  2. The design will give you the pitch, that's the angle. If you want a set Ridge height then you work back from that height for your wall plate height, (Ridge height - Rise) the angle does not change. The birdsmouth depth will be similar to the wall plate thickness.
  3. I put conduit under the slab for all pipes terminated at a manifold in the plant room. All plastic pipe with no joints. No pipes in the loft. Just MVHR, and ethernet cable, coaxial, power.
  4. We have 8 Muscovy and 5 call ducks. The Muscovies have already been swimming.πŸ‘
  5. My initial plans were to have rainwater harvesting, build hub taught me no.. so with that scrapped I needed an alternative, soakaways are difficult due to bed rock levels. In addition to this we have lots of run off on the croft, and the track to the house floods. We have already installed a pond for the ducks and this has a large berm to the back and sides so that the runoff is held back and slowly soaks away, but this winter has proved it overflows regularly, that's around 3000L extra. So the plan was to install an overflow pipe from this pond to a new larger pond. The larger pond also acting as rainwater run off capture. The larger pond will have 2 levels, a pond and then an extra layer to act as a overflow that can evaporate and or be pumped to the rubble drain in drier times. I got a big carried away with the backhoe and ended up with around 10M x 8M and over a meter deep. The overflow capacity will be around 30k - 35k L. We had to peck out some of the rock to get depth, and at the front used "as dug" rock from the quarry to form a rough and rugged stone wall, quite in keeping in Caithness. Time will heal the scars and soften the edges with planting. Due to the two levels we came up with the idea of hiding the liner under some camo net, that we intend to plant up in time. Not sure how this will stand the test of time. From the house the rainwater enters a rock filter, an idea loosely based on a post from @ToughButterCup- thanks. From the rock filter we have created a little stream that the rainwater will flow down and into the pond. In addition to this we have a pump that will take the water via a home made skimmer from the pond and filter the water from the pond through the rock filter and stream constantly. This also has a diverter to pump the water past the house and into the field to reduce the overflow capacity in drier times. This is the rock filter, and some of the pipework yet to be buried. Getting to this stage ticked a box for building control as we now handle our run off. We got our completion certificate on the house this week, yeah. There are some things to finish, the second bedroom needs decorating and trim work. And a few small jobs here and there, but in general the house is decorated, and fully functioning. We started the build in earnest around May 23 I think, so quite pleased with the effort and timescale we achieved. It's was built by me and Mandy with the odd person helping with concrete pours. 3 months in summer were busy with the cabin rentals that saw Mandy spend 3-4 hrs a day turning them around for the endless NC500 travellers.😁 We're embarking on the VAT reclaim soon. To summarise the build: 89sqm True bungalow Floor 0.094U (300mm EPs 120mm concrete) Walls 0.139U ICF with 50mm EWI and 25mm PIR IWI Cold roof 0.1U 25MM PIR 400MM mineral wool. UPVC triple glazed windows and composite doors MVHR, 4kW PV in roof, 5kW ASHP, UFH. EPC A103, Airtightness 0.83 ACH.

  7. I thought it was also linked to NI payments, where some who were already retired found out that they now didn't have the correct amount of payments and thus receive a reduced state pension, but I might be wrong, too much other stuff to think about...
  8. I can confirm, BC (Scotland) were happy with my self certified G3 compliance and signed off my build today.
  9. All the reading of posts on here at the design stage and the hard work implementing the experience of others on your own self build can be summed up / justified with just 1 image. Even when building on a very tight budget. This is my energy usage @ The Windy Roost since we got here. Upto January 24 we were in the static, we were never really warm used Air to Air heatpump for heating, hot water and cooking was LPG. We also had around 4 summer months of our cabins being used, again electricity for heating and cooking, DHW is LPG. The blue line makes me feel warm and fuzzy inside. That's our electricity for the self build, a whole house fully electric and blissfully warm with ample DHW. (With some limited cabin usage). To all self builders going through this, it's worth the effortπŸ‘.
  10. Who said anything about gas safe. I've been plumbing for years but not gas. So I did the G3, so I could do my own heating and DHW. Thus I'm not in any scheme
  11. @JohnMo, I want to look at this, as I'm not sure what I'm gaining with weather comp. When it's really windy eg last night, but not cold 6deg the heatpump was still trying to heat the house this AM. So this thread has prompted me to do just that I think I'll just change the parameters for weather comp so the temp range is 35deg to 35 Deg.
  12. 160m and you've got fifteen loops???? Id start there. My loops span rooms. I've got 4 loops, and 8 rooms / areas . 1 loop does bathroom and a bedroom, another a bedroom, Utility and hallway. I don't have zones, but I do have a buffer that I piped on to the return so acts to increase volume. Also my ASHP is a Samsung so I needed a pump.
  13. Mine too.. I've commissioned mine and I'm not registered via a scheme. I've sent the paperwork to Building control for my completion certificate this week. They didn't seem to have an issue when they came to inspect so we will see. (Scotland)
  14. Yes you can go simple, but more information is needed as 15 loops just for ground floor sounds like a massive house. My 89sqM has 4 off 90M loops at 150 centres, I didn't have the guts to go to 200or even 300mm centres. NB my UFH is in 120mm concrete slab
