Owning your own home

Oh this is interesting. Wondered why no one has really attempted this yet. Basically your keeping external walls, and the roof line, thats about it!

In our own tenement found moderate PIR board (60-75mm?) in window boarding/woodwork and between plaster and external stone where it is the thinnest (bathroom under a window) made a big difference. And then getting the stone work re pointed with the right stuff (some cement had been pushed into some joints over the years) to 1) hold the stone up 2) reduce air gaps through stone that went directly into internal plaster wall in many places made a vast vast difference. Going further with insulation you then have to go 'whole hog' and achieve proper vapour barriers, proper insulation, proper consideration of all the through holes/cold bridges like remaking the wall top plates, floor joists, entire window surround restart from scratch. It becomes a huge task so interesting to see someone have a go, and from the looks of it, really do a neat job.

Though most tenements if in good condition use a lot less KWH/annum than your average 70's to 00's semi or detached type house sqm vs sqm
