Gone West

+1 You certainly need some form of heating in bathrooms in PH. We have electric towel rails in our bathrooms which keep those rooms warmer than the living areas and the towels nice and warm. The MVHR extract from those rooms recovering that heat.

It isn't necessary if the PH has a very low space heating requirement. We decided against needing wet UFH with the resultant saving in UFH heat source, pipework, manifolds, valves etc. If the space heating requirement is low enough it can be supplied by warm air through the ventilation system. We use a Genvex Combi 185 for our ventilation, warm air heating and DHW. The warm air heating and DHW is supplied by a 500W EASHP.

In my planning conditions it specifies no loose material within a minimum distance from the road. I have yet to investigate how they would measure that distance as my driveway is not straight.

It is now. https://www.inverse.com/article/7853-permeable-concrete-is-the-mind-melting-future-of-driveways-and-parking-lots

With similar software agreements I have started a new trial period under a different name.

You can get permeable concrete, although at what cost I haven't a clue.

We had the same problem years ago with runoff from the road coming onto our drive. I asked the Highways Dept. if they could do anything as a temporary measure until we started the build. They put a 6m long ridge of asphalt about 100mm wide and 50mm high on top of the edge of the road surface. It lasted several years and was a sod to remove, but it was hot asphalt.

My BCO didn't mention Part G and didn't ask for a certificate. I had told him earlier in the build that all our taps and showers were aerating and that it was to be a low water usage house.

We had 32mm ID Polyduct specified by UK Power Networks for our connection. I laid 17m with a hockey stick each end with a draw string. They pulled the cable through with no problems.

You would need a big oven for power coating something that size. When I've had 6m long aluminium angle power coated in the past they've had to put it in diagonally.

I didn't have an 'as designed SAP' either. I had run my design through PHPP and the BCO accepted that instead of the SAP calculations.

We managed an A95 without renewables and it would be A102 with 3.2kWp PV.

All the ones we looked at can be recirculatory but we had to buy the carbon filters separately for ours.

The resin bound is easily good enough for a turning area. We had 200mm compacted type 1 then 70mm asphalt then 18mm resin bound. We don't think we have a separate cost for the resin bound because it was included with having kerbs and edging laid. We haven't laid the resin bonded yet but it will have a similar base and would be good enough for a turning area although it wouldn't be porous. There is a cheaper bitumen bonded surface but the gravel tends to pull away from the surface especially on a turning area

We specified resin bound for our driveway to meet planning conditions. We've had the area next to the road done in resin bound but further back from the road I'll do resin bonded because it's much cheaper and I can do it myself. It also looks the same.

Same here and I was lucky that BCO and Highways Dept allowed me to discharge roof drainage directly onto the lane.

It delivers warm air up to, IIRC, 50C through the MVHR part of the Genvex Combi. As we designed the house ourselves we knew all the details about orientation, glazing, plumbing etc so it wasn't too difficult to collect all the data about the house. It's other areas of data such weather data which is interesting because there are different sources for that and it can have quite a large affect on the results.

We didn't want a house that needed any form of 'wet' heating. We have a small area of electric UFH in the kitchen and electric towel rails in the bathrooms. That and the EASHP in the Genvex Combi are the only heating we have. We didn't involve a PH designer because during our research into PH we looked at several PH and some we found uncomfortable and some were test beds for new technologies. We wanted to have a house that was simple to maintain, relatively simple to build and to have as low energy use as possible within our budget. I'm lucky in that for 25 years I worked in the area of mathematical modelling and I found the PHPP not too difficult to use. I read the manual a couple of times before starting to use it and the more I used it, the more I found it useful for tweaking all area of the design.

I bought a copy of PHPP and used it to design my PH. I wanted a design that didn't have UFH or conventional central heating so I needed to use the PHPP. If you're going to have some form of heating in your house there are more basic ways of modelling space heating and DHW requirement. There are ways around orientation and glazing problems when designing a PH so the PHPP would be useful if you want to reduce your energy use as much as possible. SAP is pretty useless for low energy houses, although it is better than it used to be.

Hi, and welcome to the forum. Good luck with the build.

Think I would want a full decontamination suit on if I was going to shred that lot!

That's a substantial looking house and I'm sure you'll get it back to how you you want it. Looks like you've been working hard over the last few weeks, well done.

That's the anemometer I've got and used to set up my MVHR. It's pretty straightforward to use and you can download the results saving having to write them down.

My reedbeds are right next to my boundary as is the soakaway from the reedbeds and the BCO was happy with the layout.

@AliG I'm sorry but the skimming is appalling. We were very lucky with our plasterer who was a perfectionist and the result was that there was no need to fill or sand any of his work. He also did our Venetian plaster, most of our ground floor tiling and laid our outdoor stone slabs. If you are a perfectionist at one job you are at all jobs. You just need to have all the areas you are unhappy about replastered by somebody who is competent because you will be living with it a long time and regretting it if you don't.
