Your design specifically says that the internal skin is to be built from block, it couldn’t be clearer, read the text
Exterior skin of brick, 110mm cavity with 60mm PIR kingspan, then 100mm themalite blocks with render over internally.
agree I wouldn't have expected it - as you imply, internal looks like it should be 100mm blocks, with 60mm insulation, and re:bolting - if the breeze block meets the 7Nmm/2 that's in spec;
... does what they have done limit any potential future 2nd storey.
Any update @kai ?
that's interesting have they cut/chipped out the outer brick skin on the original wall ? ... is there an rsj in there and the original wall/door is just a facade now
Why is it so much? Out extension if similar size (3.2 x 3.8) was £15,000, although we didn't have build doors and there was no RSJ needed.Project is slightly over budget to date. When the Bi-Folds and wall to ceiling glass arrives we will be up to £18,000
The bricks will be finished Saturday then we need wait for the delivery.

Looking good, did you look around for the sleepers? (price wise?)
Yes, i found a reasonable deal. 20 sleepers = £600 with delivery. £30.00. I could have maybe found cheaper but i wanted the thicker 2.4mts long x 125mm x 250mm. Plus they offered same day delivery as i had 3 ton of soil arriving with them
Cheers any good place for long screws to tie in. The sleepers? Think my decking boards where cheaper at the time but ill have to have a look!
I thought your new doors had measles for a second there. Looks good.Update: Doors & Glass finally arrived.

The builders has been drilling away the edge today, as i need aco drains all around the extension. While doing this, i decided to steal his drill and make a start on the bottom end of the garden. I have started working on the sleeper wall for the raised beds.
