Sure this is going to catch a few unawares. new Part O (overheating) states: Any guarding to be sized to prevent the passage of a 100mm sphere, to be 1.1m high from floor level, to be not easily climbable and to be capable of resisting at least the horizontal force given in BS 6180:2011. Park K states: "section 3.1 At Opening windows except roof windows in loft extensions, see approved document B1" max height 800mm Park B states "section 2.10 bottom of opening area is a maximum of 1100mm above floor". NHBC also muddies the water, they say you can ignore Part O guarding heights if you do not rely on windows for heatloss (MVHR). also they introduce a tolerance for guarding of 100mm lower. https://www.nhbc.co.uk/binaries/content/assets/nhbc/tech-zone/nhbc-standards/tech-guidance/6.7/tg-6.7-20-guardingconsiderations.pdf So there seems to be no way to get around guarding and passing regs. Height from Floor Part O Part K Part B 800mm FAIL PASS PASS 900mm FAIL FAIL PASS 1000-1100mm PASS FAIL PASS 1200mm PASS FAIL FAIL

quite right, taking the existing roof off takes all the ceilings with it. not liveable.

you could allways knock a hole in your extension to unblock your downpipe. you would need to access next door anyway which is rude.

no, you need a chippy to pull the timber off. make a tray from a roll of dpc. https://www.travisperkins.co.uk/damp-proof-course-dpc/ndc-polipak-dpc-600mm-x-30m/p/994980

dpm looks very low compared to the floors, not dug out yet ?

dont give them the satisfaction. PC have zero power when it comes to planning. Just ignore the moron and dont respond to them. It only gives them ammunition. Next time you see him in passing just laugh at him and carry on walking.

put it on the flat roof ?

do the heat loss calcs. then do the math!

he has got the heat loss he said earlier in this nonsense thread. something about a grant and not letting them know. its all for the birds.

mist coat, spirit level. our chippy uses the pu foam gun to stick it. just let the plaster dry out fully first, you dont want mdf skirting blowing through damp.

isnt that what the filters are for ? Agree with a screen though.

isnt it illegal to flow raw sewage into a watercourse ? The trial pit shows water table near surface so rules out treatment plant ?

these not too bad for triple and very nice flush casement. R9_027 Report R7 .pdf

hardie planks look very smart.

no, unless its 3 stories or if the bend can be reached from any other part of the run, i.e. a chamber.

you need to seal it to whatever your inside structural finish is going to be. Sit the frame back so its in line with your insulation and tape it to the timber frame on the inside all the way round.

i found changeplan one the simplest to use https://www.changeplan.co.uk/heat_loss_calculator.php

just a heads up 150mm celotex and 100mm wool would fail new build requirements for a warm roof as its right on the limit of 0.12 against a limit of 0.11. Obviously you can do a worse job on refurb on extension although don't know why. If you don't have the height available as the architect didn't plan for it drop the PIR boards down into the rafters as well, use gappo tape on the cut edges to get a tight fit and don't forget to alutrix or other vapour barrier under the whole lot lapped down onto the internal walls.

We got ours from local merchant we using for the house build, they had to order it in special. Was £105+ vat but its not far off double the size. the standard hockey stick (i put them in the cavity and lintel out underground as we have a plinth and they look rubbish on the outside) fits. I spray the whole thing to match the guttering colour before fitting then cover it masking tape to protect it from the brickies.

innovative! Similar dilemma myself, we are building an inglenook but don't really want a live chimney (air tightness) and all the extra heat. We are opting to make a live chimney so any future owner can have a log burner and seal it. Then fitting an ethanol fire basket. The digital ones are expensive but look very real and are controlled by wifi! https://www.enviro-flame.co.uk/store/Enviro-Flame-BIO500-Traditional-Basket-Fire-p251642877

it's not actually that expensive to get rid off, the garage/workshop we demolished had the corrugated roof. It's low risk type so as long as you dont drill it to make dust its pretty easy to work with. Our local skip company charged £120 a ton to take it as long as we bagged it all up. You can buy a type of elongated jumbo bag that is double skinned you put them in and they can be lifted using the straps. You get a waste transfer note to keep just in case anyone comes a knockin asking questions.

worth remembering if your having 3-phase the standard box the merchants all keep wont be large enough.

they still are in low quality/value houses where the extra time and expense aren't worth it. bit like sticking go faster stipes on a 911 porker.

ignored. our useless shower take 5 weeks to acknowledge an application meaning from the date you pay the application its a minimum of 4 months.

in fact thinking about it id be inclined to put the kitchen in the front of the house and have a glass slider the length of the back wall where the sinks currently are. make the lounge at front the dining room then have a massive lounge at the back open to the rear garden via the slider.
