hello, can someone please help...

1) for an external cavity wall please rank these by strength/durability,
strongest first.

a) english
b) stretcher
c) header
d) flemish
e) flemish garden wall
f) english garden wall

If I want a 3 story extension will any of them be particularly well suited
or badly suited.

Unless you have a particular reason for spending twice as much on the labour and
extra wastage of facing bricks making snapped headers to create a different
bond, I would do what everybody else does and build the cavity wall in stretcher
bond.


2) for a Garden Wall please do the same.

a) english
b) stretcher
c) header
d) flemish
e) flemish garden wall
f) english garden wall

If the wall is ½B thick (102mm) Stretcher Bond is the only choice unless you
want to try to make the wall appear thicker. If it is solid 1B (215mm) or more
thick, I would go:

d, a, e, f, b, c

There's not too much to choose between English & Flemish on strength and
durability, it's more important to match up to what's there already. Stretcher
Bond is only for ½B 102mm thick walls and a 225mm wall built of it would
effectively be 2 No ½B walls built together without a tie, so it would be less
stable than English or Flemish. Header Bond is the least stable and ugly, and
only used on curved work when absolutely necessary.
