Personal Information

  • About Me
    I have a plot in Cambridgeshire for a bungalow near the centre of a large town. Hope to start building mid-2019. The build will be screw piles, insulated concrete raft foundation, factory-made timber frame, pitched roof with roof windows, brick skin, triple-glazed windows, gas boiler, UFH and MVHR.

    Garage green roofs / wildflowers

    My council has mandated a green roof on my forthcoming build for stormwater drainage reasons. I have chosen the simplest option. A sedum roof using a system of trays and mats. In my case the roof won't be visible, only my neighbours will see it.

    Spray PUR foam. Why isn't it popular?

    There is an example at PYC’s new offices in Wales. (They are an importer of WarmCel). The ceiling of their high-ceilinged open-plan office is fully coated with it. It’s a rather unusual and pleasing texture and they intend for it to remain on show. Good for dampening echos too I would think.

    Having an air test next week, any tips?

    Not witnessed one yet but I believe they do both and take an average of a series.

    Beattie Passive Haus 4 one

    Interesting to see. I wonder how much they cost.

    New to self building

    Welcome @Diane. Congratulations on finding a plot! I was in your position about a year ago. In this post I listed some of the things I looked out for: I am sure others will be along soon with more help.
  6. Sounds like Touchwood Homes. That is their approach. I have visited two of their builds, both good. The other advantage of having the airtightness layer on the outside is the reduced chance of it being invisibly punctured during second fix.

    Split PV System

    I wonder, can you place any panels on the flat roof at the top of the (huge) dormer, angled in frames? They may not shade the ones on the roof above.

    A warm welcome back @SteamyTea!

    extension on mbc frame

    @lizzie, I believe that your build is not MBC twin stud but MBC Open Panel 140mm (single stud).

    Oil usage and micro hydro content

    At the annual BuildHub summer party, I vote for these two to be the two captains for the tug-of-war
  11. Note that Sageglass, electrochromic glass that tints on demand, is for solar control not privacy. At nighttime, if the interior is illuminated everyone will see in easily. This thread gives some more background…

    PHPP assessment

    Personally, I would try to get your 1.5% overheating risk down a bit. Its way lower than the PH requirement (10%) but I would aim for less than 1% myself. There are many examples of 0%. As you may have read on this site, with a near PHs, summer overheating can often be more of a challenge than winter heating.

    PHPP assessment

    The advantage of ASHP, UFH and pipes in the raft is that it can easily be used for summer cooling, if that is needed (ASHP in reverse). Gas will likely be the sensible choice. ASHP will be tech-lovers choice for flexibility.

    PHPP assessment

    He/she's probably right. Are you having an insulated reinforced-concrete raft foundation?

    PHPP assessment

    Sadly for fans of the latest tech, having sensibly-priced access to mains gas usually means you should use it for heating. An old fashioned gas boiler and unvented cylinder. You just won't use very much of it.
