Yes.

Looking at your first picture I'm guessing they're around 150mm posts about 2m high. For those I would use about 450mm concrete cubes. I may be way out but I do tend to over-engineer usually.

If I were doing it I wouldn't have the pads more than 600mm deep so the ducting would be safe and I could do the pads later. Easier than boring holes for the posts.

You must be joking Clive, I have trouble remembering what day of the week it is let alone what I had in a box of bits three years ago .

No, the second time was the same as the first, except they pumped it and laid it properly that time.

We have used Cuprinol Garden Shades to paint various woodwork in the garden. It goes on really smoothly and easily and seems to last well. Lots of colours to choose from. https://www.cuprinol.co.uk/products/garden_shades.jsp

We used Siniat Bluclad board behind our brick slips, but they were only 15mm thick.

Sounds like you've got plenty to keep you busy for a while so good luck with the project, oh and welcome to the forum.

As they say time is a great healer and you do forget all the crap times during your build. Having done a complete renovation and a self build I definitely enjoyed doing the renovation a lot more than the new build. Everybody is different and you have to consider whether building a new house is really what you want to be doing for the next however long.

I fitted a silencer on my supply circuit which is silent, but didn't bother fitting one on the extract side and it is possible to hear a hum in the bathrooms from the vents. Fitting a silencer will affect the airflow but to what degree I don't know. I commissioned my system after everything had been installed. My guess is that the concrete sleeve is probably ducting. If the ducting isn't insulated then condensation will form much further back in the ducting and mould is more likely to form.

Hi and welcome to the forum. I considered Sunamp in my build but am glad I changed my mind as there seem to have been quite a few problems with them. There is an alternative coming to market next year called Tepeo which looks to me like a big storage heater with water pipes. https://tepeo.com/technology

I'm not sure I understand completely. What part of the building has got the large thickness of concrete that the extract duct is in. My house is all timber and the ducting is insulated right up to the vent and doesn't have any mould inside. My total wall thickness is 500mm. I don't think replacing the square vents with smaller round ones will affect the condensation but it may reduce air flow.

I get condensation dripping from my MVHR external extract vent for certain weather conditions. It is normal, which is why the ducting leading to the external extract vent should always be angled downwards slightly to allow the water to drain away.

That's what we did, so it was at least half British. Rehau Geneo profiles with windows manufactured in UK.

I used gel PU adhesive to stick some brick slips to the EPS upstand on my insulated foundations. They are still there many years later. https://www.axminstertools.com/titebond-greenchoicetm-premium-polyurethane-construction-adhesive-ax836048

We used NuLok. We did all the membrane and battening and I tiled the single storey area. There wasn't time to us to do the whole roof so that was done by a team of NuLok roofers.

Is there any reason why the PIR can't be glued to the racking with a few screws from the inside to hold it in place.

Similar construction to yours but I fixed 100x50mm battens to the outside of the racking, drilling from the outside and screwing from the inside. Friction fit 50mm Rockwool RW6 batts between the battens leaving 50m cavity then cladding.

Hi Andy, welcome to the forum. Sounds interesting, any details.

It doesn't look like the Chrysotile sheets I had removed from my bungalow but there are other types of asbestos and I'm no expert.

I wouldn't disturb it anymore and would get it tested. I used one of these:- https://www.amazon.co.uk/Asbestos-Sample-Testing-Instructions-Postage/dp/B0862B9JZB/

Quite possibly. The new bungalow next to us has a half hipped wall facing us which had the walls bricked up to eaves height by one set of brickies and the bit above was done much later by different brickies. The bit above has different coloured mortar which hasn't been cleaned off the bricks as well as lower down. Does not look tidy.

We lived in our old bungalow whilst building the new house in the garden. The advantages being that we were on site all the time and all the services were on site. Removal of telephone line was £0, connecting water £0 and electricity was £476 for removal and £636 to connect.

Our thermostat is set at 23C. Anything below that is just unpleasant.
