  1. No. Not a better answer. Putting someone like me in charge of anything usually results in some kind of disaster... We do, however, need a process to combat such organizations when it becomes clear to all outside that it now mostly exists to forward the organisation itself and not the thing it was originally created to achieve. This is usually frowned upon because it usually costs jobs. Regarding the original point of dealing with this legislation by removing the wildlife before putting in planning - it's already happening with the scheme we have. I know I looked at my land very carefully before submitting planning. I didn't do anything other than removing lelandii trees that were far too big and a diseased oak stump though. I am fairly sure that I definitely have not aided bidiversity. I couldn't even stop my woodpeckers from destroying the bat boxes I put up to satisfy a planning condition.
  2. You haven't seen the project management department at work!
  3. Proof as ever that bureaucracy becomes self sustaining disturbingly quickly.
  4. Yes. It is a protected staircase. Can't have an escape window on the top floor so I have gone with the multiple exit option and agreed it with my BCO. Thanks for confirming the 30 minute minimum - it makes life a bit easier elsewhere.
  5. Am I correct in thinking that a 3 storey single occupancy detached house requires 30 minutes fire protection for the escape route? There is only one way out of the top floor, but then multiple means of egress on the 1st and ground floors. My current plan should give 60 minutes for the walls but this is influenced by other requirements like sound insulation.
  6. The Paslode nails I used had a certificate to say they complied with the BS because they had at least equal pullout resistance.
  7. The willow trees to the south do currently shade the panels in winter. But they are being topped as part of the landscaping plan. We just can't get to them right now and there always seem to be more important things on the to do list!! SSEN asked to send a representative to oversee comissioning the solar installation. It was either because I am not a member of the right installer club or I wanted to install well over the usual amount of panels. I forget their reasons.
  8. As usual it feels like progress has been glacial. It probably hasn't but most of the jobs this month aren't exactly visible. The first job was to construct a cabinet for the switch fuses and electric meter since the old back-to-back meter boxes had degraded to the point of uselessness. This of course displaced the drainage installation activity for a while. I did make some progress here too but we are nothing like finished yet as another tonne of gravel disappears into the ground... Casting a small reinforced concrete ring beam. The ducts for house and garage SWA in the centre. It turns out that making "model" buildings is a bit of fun. Construction of the timber frame for the meter cupboard, now known as the Woodlands Folly. All materials were offcuts from the house. Meter cabinet installed and beginning to fix the cladding. Again, everything is from house offcuts including the slate roof.The meter will be accessile from near the road - covid safe meters might catch on! Almost finished folly. UPVC soffit and fascia were found in a pile in the woodland during the summer chainsawing work! The inside is lined with floorboards since even I am finding it difficult to burn them. Switch fuse units have been fitted to test sizing ready for connection. One for the house to be connected immediately and one for the garage that can wait for the time being. In the fullness of time a consumer unit will be fitted to the back wall so there is accessible power in the folly for lights and car charging. Nothing like test fitting a consumer unit in a wall that isn't really there... It's a recessed BG unit fed with SWA from the folly. The "wall" can't be installed properly as yet because screeding the floor is one of those little covid/brexit (delete as appropriate) difficulties in the supply chain along with blue facing bricks. But at least I get to have something to look at even if it doesn't do a great deal. I installed two 2.4m earth rods since there's no PME supply to site and it isn't likely either. The earth test gave 2.7 ohms impedance so well within requirements. At least the PIR is all fitted, even around all the tricky areas with ducts through the floor. I am considering decomissioning the death saw although it seems a friend would like it to make insulation strips for his roof trusses. Meanwhile, the same friend wanted somewhere to practice drone flying. This was something I was happy to assist with! These are a couple of stills from a flight showing my extremely untidy site. One day I will have the drains covered up and the treatment plant located in the ground! And maybe further in the future I can have a garage too! But the roof still looks good. Now we get on to some very good news. After nearly 9 months of waiting, the arch windows have arrived! First the frames. They even fit in the holes! And then a week later the glass. I now have a little problem of getting some large 50kg glass semi-circles into the attic without a pair of staircases or scaffolding. This is going to be interesting and may involve heavy plant. What could go wrong??? Finally this month it became urgent to get the solar panels doing something more useful than just keeping the rain out. (My connection offer was due to expire!) So I fitted the inverter in the attic on the first piece of house to be boarded. The DC wires still need clips and some bits are decidedly temporary solutions but all of it passed witness testing so it is good to start generating. Another 6kW of solar on the grid just in time for winter.
  9. Yes. 3dB is a doubling of whatever you are measuring in decibels.
  10. Thanks. The external terminal examples do help a bit. Not sure I have an actual issue. It's more about what solutions other people have employed and me thinking about an optimal solution - does vertical separation help with anything or does it make no difference, and figuring out if there's a sensible maximum for horizontal separation. I'm not short of space. The ventilation guide looks useful.
  11. I am drawing up the duct routes this week ready for some 1st fix progress and I have two options for MVHR. Reading the threads here it looks like there is a requirement to separate the intake and exhaust of the MVHR by 2 to 3m and keep them on the same (ideally sheltered) wall. Both of my options achieve this, but does it make a difference if the separation is vertical or horizontal? Option 1 has vertical separation with the intake low down on the wall (apprx. 3m above ground) with the exhaust just under the eaves at around 6m above ground with up to 2m horizontal separation. Option 2 has both intake and exhaust at 6m above ground. Horizontal separation can be up to 10m but the easiest option gives approx 5m. Option 1 presents some inconveniences to other bits of infrastructure so unless there's a compelling reason for vertical separation I would prefer option 2. I would very much like to know what anyone else has done.
  12. Good luck. They don't appear to be written as nicely as the Scottish regs. How did you go about filtering the air extracted from the kitchen if the mvhr is doing the work? My architect was concerned about this to the point of advising me not to put the kitchen air into the mvhr.
  13. With you there! I made friends with the people at work that do the air cooling designs for some of our equipment a while ago. 😉
  14. They are a good call. Not seen that particular brand before. Thanks also for the design recomendation. I don't believe there's a need to revisit my design at the moment since the overall requirements are still close enough to the initial design.
  15. On careful consideration it was probably when TSR2 did not go onto production.
