looks great! can allways add more patio in the future if you find more space needed. I got the mrs to size ours, set out table/chairs sofas etc and just made sure plenty of room to manovre all round them.

5 ton machine lift it easy. 3 ton while being able to lift 250g no issue hasn't the reach to get it off the lorry.

In order to not mislead. 300mm eps > 100mm celotex for BETTER performance.

letter before action, get something in writing from BCO saying its wrong. Judge will need this rather than say so. See what the original builder says. Small claims is very easy to do, its all online.

that is the downside of cheap indian sandstone, its a bugger to keep clean and look fresh.

better option is 300mm of EPS. half the price of the equivalent celotex and far far superior. the standard mindset from architects/builders/specifiers that only 100mm needs to be allowed for insulation in the build up has to change.

v2. build a box around the heat pump with 200mm celotex, fully air sealed. Smaller rad inside this time. Put a couple of single room MVHR units into the box with heat recovery to provide air flow. patent pending.

what if you fixed a radiator in front of the heat pump and sent hot water from the heat pump into the radiatior so the heat pump was allways nice and warm. This would heat up the air and give free heat permanently. patent pending.

41 x £3km2 not including steels, struct eng requirements, flash fittings etc. This can go up or down (mostly up) depending where in the country you are. £120k+

i wouls say concrete pantile cheapest, clay next but look best. then slate.

mcs waste of time for solar, leave them to ripoff the heat pump installs. the inroof micro inverters are very good, a little more expensive but better features. they fit underneath the panels so you only end up with a single cable entering the loft.

fake slates are cheaper and very hard to tell they not the real ones.

sounds like the builder had shares in litecast .....

the 'modern' build methods like timber frame, icf are quick but are double the price of a traditional build. so unless you are planning to have a rapid build and move in within 12 weeks they offer very poor value for money. Much better to spend that money on improving the fabric of the building, having very good insulation and air tightness etc

not the painters fault. Those are massive 'pops', were the correct screws used ?

how much PIR ? 75mm is average for screed.

like this. https://www.toolstation.com/galvanised-cover-frame-24-x-18/p94026?utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&mkwid=_dc&pcrid=&pkw=&pmt=&gclid=Cj0KCQjw7PCjBhDwARIsANo7Cgm522m2PwNr16AiI-aV6V-d7ILWmmZSDaLjt0YJQETs2kdpoD0sZIoaAtGQEALw_wcB&gclsrc=aw.ds

nope.

disagree our battery works great. Value is subjective. a 4k kitchen functions just as well as a 40k kitchen etc

planning for worst case, reality should be half of spec mostly. dhw free for summer and most of shoulder months (10kw solar) cheap rate in winter. will have a read of link thanks.

nah they have the metal ones in a frame.

all the builders merchies stock them.

chiller unit is a cooler yes not a heater. Your right they wont cool enough on their own hence using the fancoils as well as the ufh to provide cooling.

yes, a length of 4x2 on floor and another on the roof, you may need noggins in between the rafters to take it.

heat pump - not decided yet but it will have to support cooling out of the box. Wont be MCS scam install either. control/flow/valves will leave to the plumber. Your missing a trick on solar. It's cheap and has immediate payback. 75mm cavity (0.6 is a typo I would guess?) may just scrape past regs but its very very poor U value even using expensive insulation. Insulated plasterboard as well unless you can make the cav wider. for showers im allowing 5 simultaneous @ 19L/min and the washing machine, dishwasher etc. basically worst case. accumulator to maintain flow and starting of with 2 x 300L with space for 2 more. see how we get on. I'll keep adding them until running out of hot isn't an issue. Poverty mode for hot water isnt an option.
