Suggest you accept compensation and then get them painted when the build has finished. You might even come round to liking the colour! I have slate grey inside which contrasts with the internal walls and frames the views nicely.

74 miles per US gallon would be very good

I am almost fully metric but litres per 100km means nothing to me. At university we used American textbooks for some topics so I had to get my head around Slugs in measurement of viscosity.

What does it smell like?

We are still a bit mid Atlantic which confuses people on both sides. For example we drive miles (and yards) and consume fuel in mpg but buy it in litres?!

Got mine from TK stairs in oak with MDF treads (carpet). They didn’t offer ply as standard, give them a call but you may be paying more than oak for something non standard.

Not everybody has a borehole so maybe ask someone who does directly. Either post on an existing thread or search for someone who might know and tag them by @name.

Have you asked them where this requirement is defined? Not in building regulations AFAIK, do they have their own list of tests/certifications required?

All depends on your insulation and air tightnesses levels but £6/day during this cold snap does not seem unreasonable, especially with 22/24 degree set points. My set points are 18/20 degrees but I do have a wood burner for the evenings. Do you have UFH, charging it when rates are low (overnight)?

Thanks, appreciate the honest review. A few points to think about but I am not put off, still seems a good system

Planning drawings only, BC drgs not needed

Planning decision notice and general drawings, I sent floor plans and elevations. They just need something to verify that you have permission and rough scale of the development.

Other way round, I have windows in RAL7015 Slate Grey and was looking for matching profiles etc. Found BS18B29 a close match but depends on product, surface finish and manufacturer.

Maybe look at the work of good architects for inspiration (and possibly hire one)?

I would be inclined towards battens, have you installed underfloor heating, that might make a difference?

I am looking at a similar system, how have you got on with it?

As above, depends on the MCS installer’s calculations … which depend on assumptions made. You certainly don’t need UFH upstairs but the calcs may show the need for some heating in the bedrooms. I went for (wet) towel rads in the bathrooms and radiators in bedrooms, were quite cheap to install but rarely needed.

I also tend to avoid the latest fads. My first house had open fire places in every room and leaky sash windows, plenty of fresh air without any fans. Now though, with modern standards of air tightness and more concerns about VOCs, CO2 levels etc. active ventilation is essential for most new houses.

I agree with your comments about passive cooling. MVHR doesn’t help much with cooling but has so many other benefits and it is not necessary to spend £12k. I self installed this unit and spent another £1k on rigid plastic ducting and other materials. Of course you can spec something more sophisticated but this works very well and I wouldn’t want to live in a house without MVHR and I don’t want people to be put off by these quotes. https://www.ventilationland.co.uk/en_GB/p/itho-daalderop-mvhr-hru-350-eco-unit-lr-rft-low-rise-350m3-h/9945/?gad_source=1&gad_campaignid=22563121607&gbraid=0AAAAAB0qKPDJ-kmgBYRAOrw1rwDPtmlOW&gclid=Cj0KCQiAiKzIBhCOARIsAKpKLAOKcw9T7CHFnPu-qqBlrN6gM85GPOdAMbqVvfGZpXWti5CANHf1dMwaAjWTEALw_wcB

Yes, trades must invoice zero rated for all labour and materials. You can buy materials and reclaim VAT as long as they are on the eligible list https://www.gov.uk/guidance/goods-and-services-you-can-claim-for-under-the-vat-diy-scheme Your accountant is talking nonsense 🙄

I think it looks better with different wall cladding to the roofing material but that’s just my personal preference. The slate roof will look absolutely fine and will be much cheaper than zinc.

I agree the entrance elevation looks a bit odd. Do you have a drawing of this arrangement? I think it would look better with the same cladding to ground and first floor. Also the same width, don’t know why the first floor is the same width as the roof?

Don’t believe these prices, wouldn’t be paying with my money unless credit card covers it.

Don’t need one, just enjoyed watching this. Useful for small jobs, but too cheap to be reliable?

Just access and mobility around the house which is arguably more important than level entrance ways. I actually like the interest that split levels lend to an interior but it is not practical for everyone.
