The advantage of a fillet under the bottom batten is extra ventilation (IMO). But a bit more faff 🤷‍♂️

A common mistake is missing the fillet or extra batten (or facia) to lift the last tile (because it does not have a tile below it to rest on. ) and the last tow of tiles is at a different angle to the rest.

With OSB underneath you need counterbattens to stop water being trapped behind battens and rotting them as the membrane cannot drape.

If your worried about noise to your bedroom, or neighbours, you could time it to not come on at night!

I am another for your own STP. I would not touch a biodisc with a barge pole, go it alone.

You have not said if you have paid them or not, if you still owe them money it puts you in a stronger position. I agree with above, not good enough.

Actually despite me quoting my plant room it does not have the DHW tank (as this is better centrally to the house) also the UFH manifold is under the stairs, better for distribution and the MVHR is in the loft for easier pipe distribution. The plant room has fuse board, heating buffer tank, expansion tank and pumps etc, and a washing machine. Oh and a cupboard for all those bits and pieces you can never find 🤣

+1.

+1 for a cupboard (mine was off the cloakroom) and as a Luddite less is more IMO (and less to go wrong in the future) this is my idea of tech

I had no floor gulley but the drain stack was in the corner so a branch near the floor a with blank enabled me to use it as a drain in case it was needed.

However a 600mm drop over a meter is doable with a gradient, rock garden etc without getting into structural stuff surely?

With my build I had a plant room cupboard in the back of the cloakroom. Frankly you need to draw it out on paper to scale against the wall to see if your “kit” will fit. With the “cupboard “ I did I didn’t need to have “standing room” and double doors to access everything (I even had a washing machine in there.)

Why not? But surely we are only talking about reducing a small amount, a foot maybe 🤷‍♂️ yes @Gus Potter input on trees/foundations will be good (he helped me with my garage foundation ).

As we are encouraged to use less with LED lights etc I can only guess it’s the amount you can sell back to the grid with PV 🤷‍♂️

Called being over a barrel.

Whenever I used to quote for work I always had a caveat that the price would be negotiated before continuing if unforeseen problems were found. Only fair.

As I pointed out earlier tile slippage due to rotten battens can happen but not for many years IMO. Eaves trays are a modern thing, felt left in sunlight will disintegrate eventually (and looks rubbish 🤷‍♂️).

No one questioned my figures (which I made up because we were in clay but had a ditch to use 😇)

Either will work but the advantage of no 2 is you know there is no voids

Guttering should not “pool” but dead flat guttering will work, personally I always created a little slope when installing guttering. he took 6 weeks to do a weeks worth !!!”!

Why do you need more? Make it bigger 🤷‍♂️

As said above it won’t need support the brick pillar and concrete lintel is doing their job, just fill the hole with bricks if you want to tidy it up.

Hi and welcome to THE forum for self builders, I started wanting to build in straw bales and ended up brick and block. There is no right way to build and lots of options. Just remember there is no such thing as a stupid question, stupid is not asking. Lots of real world knowledge here on all sorts of levels. Bring on the questions (and we like pics 👍)

Only when on certain tariffs surely?

You can’t cure stupid 🤷‍♂️
