Airproofing is an issue/problem with Durisol & Isotex, but not with Velox.

A quick answer is £1500 to £2500 per square meter. The best place to start is getting quotes/estimates from turnkey companies as TBC said above . "good reliable experienced builders" availability is going to be the main issue.

As ToughButterCup showed the blocks butt up to one another and create a small gap between them. I have often seen daylight looking out before any coating (plaster, render, etc) has been applied. The woodcrete insulation is good, but just like a woolly jumper you also need to wear a windcheater to get the full benefit of the insulation. Velox uses woodcrete but has a continuous concrete layer and hence before any coating has a much better airtightness. The biggest loss of heat in a house is air convection currents caused by poor airtightness.

Have a look at Velox http://icfsystems.co.uk/. The major problem with a block woodcrete ICF system (Durisol, Isotex, etc) is that they have gaps.

Well said

toasters are a WOTAM (waste of time and money) IMHO

IMHO if you mention or threaten "liquidated damages clause" you might never finish your house

I building a temperature monitor and logger at the moment. From a hardware point of view I'm using DS18B20 (12 bit gives 0.0625°C), Raspberry Pi Zero with a 1-wire HAT.

ISOTEX is approx £70/square metre. ISOTEX is an MMC (Modern Method of Construction) and it can't really be compared with standard construction and timber frame IMHO

It's nice and small and uses photoacoustic sensing principle, that's the development board sitting on my Apple keyboard

Have a look at the Sensirion SCD41 sensor - https://www.sensirion.com/en/environmental-sensors/carbon-dioxide-sensors/carbon-dioxide-sensor-scd4x/

I'm building a true CO2 meter based on the Sensirion SCD41 sensor with a Raspberry Pi. It might also include the SGP40 VOC sensor.

If you want to reduce noise in a down pipe then a Syphonic drainage system is very good, more commonly used in commercial buildings.

I think Building Regs says you must have a aerial or provision for one.

The problem with Graven Hill is that a plot for a 3 bed house is £185K with a plot size of 217 m2 and you have to use their contactors to build the foundations.

We are mainly self-builder in this group. A good builder will be able to answer most of your questions and give you a price. That said good builder are hard to find, because they're all busy.

With EVs, 3 phase is going to be widely needed IMHO.

If the works are Contestable they may be undertaken by a suitably accredited Independent Connections Provider (ICP). Contestable works include the installation of cables, substations and other plant associated with the new connection.

I just read it as "Check this out, bit chuffed with this, never used a bender". What over the knee! "before" was further down the page Very nice

Yes, and good prices Just placed another order for Fresh Sawn Structural Grade European Oak, actually to build a 4 poster bed!

Have a look at ecforestproducts.com/oak-beams

Congratulations

Welcome to BuildHub, a friendly bunch with a fountain of knowledge.

Yes, outward opening doors are more secure, hence the reason why inward opening doors are preferred by the fire service, easier to get in.

Apologies, I missed that post.
