I used to subscribe to the Wharram community newsletter 30 years ago which was the source of the discussion. Those magazines went in a house move many years ago. I think you have got re. turbulence. Not sure but I do hear that racing sailors like slots and the associated lift. Instead dream positive, your NuLok roof has survived its first major wind stress test.

A British catamaran designer called James Wharram use to specific slatted decking based on similar thinking, he believed a catamaran with a slatted deck bridging the two hulls was less likely to flip. Decades later he conceded that a high-end aerodynamic expert had explained the fallacy of this belief. Anyhow those straps look serious.

I wonder why they maintain this stance given that BuildHub is so well indexed by Google and your experience is just a few clicks away for any potential customer.

This defies common sense. Relative to absolute zero (-273) your maths looks plausible but surely what is significant to ASHP is the heat capacity available down to the minimum chilling operating range of an ASHP. If an ASHP can chill to -10, then the available heat capacity at -5 is half of that available at Zero.

Mine sits on 12 block pillars though the final leveling required 10mm to 30mm of wooden chocks and shims. This is a valid concern, I don't want any of these to go airborne and crash through my selfbuild neighbour's newly installed windows.

Just seen the weather forecast, looks a tad lively north of the M4. The second blow Tue/Wed night has a 60mph gust prediction for the nearest offshore weather buoy off the Lincolnshire coast. Any strong wind tips relevant to a self builder? Top of my list will be to double check the wooden chocks under the static caravan.

Given the gradient did you consider the more angular Cotswold Chippings?

I have had water and electricity laid on for 7 and 5 months respectively and not yet seen a bill. Do the utility Co's tend to forget about billing until Building Control signoff on the assumption that consumption will be trivial until occupation?

Is there an association/concern re. your other post about moss growing on the tiles? I might be reading too much between the lines here but is there a concern about moss gumming up the drainage channel?

Just throwing in a random thought at this point. Is it possible a vacuum is building up on the house side of the pump when it operates due to a blocked breather pipe?

Could it be saturated? This is why I asked the other day if prior problems coincided with winter months?

The two man pro brickie team who built my neighbour's 1700 sq ft house last year used a little pulley and attached a rope to the handle of a 6 brick lifting clamp. If I can work as fast as them I would be happy. Oddly the whole house scaffolding included an extra platform which was intended for a telehandler to reach.

@ProDave and @recoveringacademic As Kwik stage users what do you think of this plan? My diyMax self build is likely to be slow and I have been toying with the following plan for scaffolding. 1. Buy enough staging for my garage 7.2m x 5.6m and high enough for roofing of the single story garage. 2. Use the same scaffolding on the main house to get up to first floor joist height moving it as necessary around the larger perimeter of the house. 3. Get pro scaffolding company in for a short term rental as the main house build proceeds from 2.4m high to gutter height. The two story perimeter of my house is 40m.

Kitchen open plan to stairs?

= £72 per m2. This link (2015) suggests a much lower £27 m2 for Spanish slate. https://www.homebuilding.co.uk/how-much-does-it-cost-to-tile-a-roof/ When I looked at in-roof PV mounting panels they came out at nearly £30 m2 plus the per meter squared cost of the actual PV. I wish it was true that in-roof PV mounting would be subsidized by the saving of an expensive roof cover but I am not seeing it in the figures.

Time for some lateral thinking, how about a paper tower dispenser and a camping torch? Is this proposed setup for your own convenience or are you motivated by legislation and concerns over workforce welfare obligations?

How old is the drainage field or how many man-years of effluent has it dealt with? Also when you last had problems with a suspect pump was it towards the end of winter?

How are the tenants fairing? They have been crossing their legs for a couple of weeks now ?

Can the window in the living room be configured as an egress route?

If it plugs together with anything like the reliability of Scalextric track then I would run a mile.

Having sailed north and south across 50 degrees of latitude many times i.e. the English Channel these numbers are fused into my brain.

Pretty sure it wants latitude to calculate the elevation of the sun for each hour per month. You would then need to fiddle the numbers for your local noon which is a small adjustment, about 5 minutes I guesstimate for your part of Kent. The high degree of shading shown in the OP with your default overhang looks about right for khartoum.

Have you missed the 5 for fifty when entering the latitude? Edit: The latitude of Canterbury is 51.2802° N

Having frequented this forum for a year I reckon the most painful charges originate from the clipboard-hugging tickbox sector of the building industry who are often able to charge what they like because they are empowered by legislation or monopoly.

Without a calculated internal floor space I find it difficult as assess how effective a house design is. I am guessing about 2300 sq ft in your case? The working area of the kitchen is 5.4m x 5.0m which implies the cooks will quickly get to 10,000 steps daily on their fitbit. The office is ginormous for a house and I suspect half of it will become a dumping ground for things like the treadmill that has fallen into disuse. If the location shown for the garage is to scale then I doubt you have a viable turning circle outside. Also have a look at my recent thread discussing garage door widths, the community decided that 2.5m is a reasonable target width. I would be tempted to reverse the stairs and have a 90 degree turn with the bottom step starting 300mm to the left of the dining area door because the door swing and fancy bottom stairs step arrangement looks congested at the turn for the toilet/study. However if the topology works then what you have is a grand entrance hall statement.
