@Iceverge thanks for those. Unfortunately living room too small for us. Kitchen on the front not what we want and think its a hard no with the stairs open onto the kitchen. Think stairs in current house ok at 42 deg and we were in bungalow previously! I think there are 13 risers in current house. Agree with the high ceilings, last place had 2550 and felt a lot better. I will have to see tallest eaves height i can get away with as I'd want eco trusses and decent ceilings if poss. I got AI to do the sums for me the other week I just cannot see 200mm cavity ever being worth it. I feel the same way about 3g tbh. When I looked at the sums the payback period is longer than the window will last although someone the other day was saying the costs between 2 and 3g wasn't as big as id expected.

Its funny what different folks want. All our houses upto now have had minimal wasted space. The one we're in atm is the same with gf cloaks under stairs and ensuite/ dressing area above the stairwell. I want a slightly more open space this time. I don't want to feel like every nook and cranny is accounted for. I'd much rather see a dresser under the stairs in this layout and double glazed doors into the kitchen. In the olden days you'd have probably had "the" phone here! Hall will feel less cramped even though its wasted space. Likewise upstairs I'd like a window in the middle at the front with a bookcase, chair or maybe even ironing board 🤣 below the window. As for planners they do your nut in. Imo all the best looking places were built before the planning system ever existed. Although I think some of the blame lies with building regs aswell now. Fancy saying to someone you can only have 1.5 storey in your neck of the woods. What does it achieve? You've still got first floor windows. Your housing density is much less up there anyway what issue is it to build full 2 storey? Blood sucking bureaucrats trying to justify their job. There are some great looking 1.5 storey places but a blanket rule of no 2 storey is a joke.

Even with that garage and bedroom above included in 11m? Yeh I used a ridge beam before it was actually a 1.2m deep square truss which spanned the walls then mono trusses off either side. They do work well but I just dont want that this time.

What about the internal connectors which get you into a cut off flush pipe or from pvc to clay. Lifesaver. https://www.ebay.co.uk/itm/376303778138?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338590836&toolid=10044&loc_physical_ms=41471&customid=92f510b7e1d311980908791a8530426b&gclid=92f510b7e1d311980908791a8530426b

Would it be noticeable compared to a dry aircrete block though?

Just fill the car or van up more often so dont NEED fuel when a massive queue. Maybe every half tank.

Yours looks longer but thinner @ProDave? Can't quite zoom in on sizes maybe 13x7 overall? Works well. Im trying to keep the same footprint as existing planning as I get the impression from planners they will make my life easier. Existing plans are 1.5 storey but informal chat with planners indicate they would be open to 2 storey. I just cba with the detailing and insulation on 1.5 storey now. I just want a simple truss roof with an airtight membrane and 4 or 500mm of insulation above. No intermediate supporting ff walls etc. Did have ideas of potential 2nd floor but unnecessary.

North is front, rear is south. Plot is a garden split from corner house. To the west is blank gable of neighbouring house. To east is host dwelling but strangely only 1 first floor window facing and not main bedroom. Host dwelling has been basterdised. Permission already granted for this footprint hence me wanting to keep the same even though resubmitting planning. Existing west elevation has double garage which used to serve host dwelling. Will try to keep that adjacent to new build. Possibly replace front corners of brickwork to match new build. Planners may be ok with 1no small obscure window to ensuite on first floor. To the front is tall privet hedge and then houses over the road. Will likely have driveway gate so no unexpected walk up visitors front elevation. To the rear is garden then fence, no overlooking to South. to be honest I copied a bit of the gf layout we are currently living in and current house works for us. Apart from utility on opposite end of kitchen which does seem odd. Current utility gets no use for cooking activities though. Current gf cloaks is under stairs. God knows how they managed that its a modern house. Probably does comply but only just.

We have occasional visitors who would really appreciate not needing to use the stairs. I was thinking you need a gf cloaks anyway, for the sake of a shower and an extra door it becomes an accessible ensuite. Probably be used as a kids room most of the time

Deffo doing the right thing getting the evidence. The problem is getting all this stuff before you shell out for the plot. In my case vendor wasn't willing to do the graft so I moved on. Plot still for sale

It's alright the fire brigade saying that its making sure you don't have an anal BCO who refuses to sign off. That's the nut you've got to crack. A lot of money to put on the line without that in black and white.

I have actually but decided against it. What's the benefit?

Massively depends. A subby bricky may or may not supply a mixer likewise a laser too. Don't discount someone just because they don't supply these things they may be a skilled tradesman. Now if they start saying they haven't got a trowel or a level that's when you've got to worry. Not sure why but joiners usually supply everything they would need and are usually anal about their kit

I think potentially you'd only need one. I'm sure some people have said not every house even needs one. One at the end of each of those runs won't hurt

Is it? If you have to start featuring something with the access chamber. Couple of slip collars and a y branch jobs a goodun and its legit.

Just y off an existing branch

Id say marketing gimmick used for the bling elements.

This is why when I plumbed it into AI it was basically saying 3g will never pay. Excluding any comfort factor 3g may afford over 2g. How much are the units are they roughly 50% more expensive as half armchair glass again? The u value difference between 1g and 2g was alot bigger than 2g vs 3g

I had a guy come out and commission mine 2 years later as wasn't happy with my job never used anonometer. The guy was reccomended by firm who supplied the gear. Complete chancer. Used a hot wire tester or whatever it is with no hood. The cert he issued me balanced up the sums but was missing a room supply terminal. When I told him this he just added that into the figures and then it didn't balance. He had just made up the numbers I think. Needless to say he wasn't paid.

Whats the average lifespan of 3g units?

Just a printed spreadsheets with flow rates that tally up. Maybe a word document stating you've commissioned it as per manufacturer's instruction. Job done. Did you use an anonometer?

You will find span tables online for joists if needed.

Reason I ask about ufh manifold is because gf cloaks is a bit long. If I squeeze the length 3 or 400mm I could gain a good central cupboard accessed off halfway behind shower. Basically ensuite and gf cloaks is carbon copy then can just order 2 of everything.

Would uvc actually be better in ac or plant room? Guessing plant room but not much else to do with that space. Getting ahead of myself not but ufh manifold better in plant room?

B1 feels a bit boxed in there
