So 5 years in and think I now understand the summer bypass has minimal effective function in the warmer months. It's 16c outside, it's midnight but the air supplied is at 23c with summer bypass on or off. I naively assumed with the bypass on it would supply the external temperature and have a moderate cooling effect. Is the heat exchanger supplied by the extracts? Help.

I made and fitted the fascia boards first before fixing the horizontal Douglas fir cladding. Does that help?

@AdamSee Yes, lots of hanging around by the fingertips.

My son made some sort of hangboard? above the door, he removed architrave then used long wafer screws to fix through to stud work. Not moving. Then left home.

@Tom Home made cut stringer yet to be finished, temporary hand rail etc....yours looks fine.

I had a problem with being recommended and purchased a Vent Axia based only on area and not volume. All based on 2.4m ceiling heights. Due to exceptional ceiling heights in 50% of our dwelling the MVHR could not reach the minimum requirements for building control even at 100% boost. I had to be a little creative with figures for BC to pass. However our MVHR runs 24/7 at 30% and seems adequate for our needs. The Zehender 600 has an air volume of up to 600m3/h at 200Pa.

@flanagaj Like you we are south facing and have no shading so do overheat. I plumbed for AC in the first floor bedrooms and the main family room as seemed simplest to install. We have PV so running cost is offset and have ASHP for DHW and heating. We cross ventilate in the evening to purge the house as @Russdl. Would consider built in external blinds ( no view, natural light during the day) and solar glass next time.

Definately deserve a beer but careful now as you will be asked to make fitted wardrobes next! It happens. The Kreg is a bit unnecessary as cheaper tools for hinges are available.

I have just done this, WC, shower, sauna and a kitchen sink. We have a Vortex TP, simple but functional design with an air bubbler. Its about 30 metres from the house. No penetrations through the building as @Nickfromwales mentioned. Scrappy image below.

I have a vent pipe about a metre before the treatment plant main inlet and an AAV just above upstairs WC. Did not want a vent pipe penetrating the building. BC happy with that.

I have been using this on Cedar, did buy 5 tester pots of different product but settled on this: https://www.protekwoodstain.co.uk/wood-stain/timber-eco-shield-black
