Getting closer to wall building time now the weather has warmed up a
bit; if only it would stop raining!


I will obviously need to cut concrete blocks - I will be using the
'medium density' blocks for external walls with no rendering.
[At least I think the normal ones are described as 'medium density'
- it does beg the question as to what 'dense' blocks are.]

Any idea how much to allow for wastage?
I am not the best cutter of bricks etc.


I'd order what I needed to be delivered, and then pick up a dozen or so at
a time if any extras are required, you are better under ordering with
blocks.


Also forgot to ask, are you intending adding any butresses? - if the wall
is longer than 4m, you'll need a buttress in the middle, basically just a
stack of blocks, tied into the main wall with tie wires on every course


I will need to add something in the middle of the back wall as it is 7.8m
long.
The front wall will also need some extra support and I am contemplating how
to work this in around windows, doors, and a place for the stove.
On the front wall this may end up as a fireplace for the stove to provide
sides for protection from the hot metal.


I'd be wary of enclosing your stove too tightly (if at all) as it'll
stifle it and take longer and use more fuel to heat the space up.
Could you praps place it in a corner and let it convect and radiate
out from there without being "boxed in"?
