Evenin all, embarking on a project to convert an old 70s Atcost reinforced concrete framed agricultural store to a 4 bed passive house for less that 1300 quid a m2. It's being built under permitted development, which has its challenges.
Hoping to keep it VOC and gypsum free. Had to use OPC in the foudations and fiber cement roof, but hopefully that's it. Vicat and lime mortar used in a 5 course high plinth which will be filled with Geocell then a 100mm thick lime screed slab on top.
More pics to follow, but any words of wisdom appreciated. Some awesome information on here and really inspiring chat.
Looking forward to contributing my mistakes to the community ?
Cheers,
Darren
