What is the usual way to tie in new brickwork when old and new have
different sized bricks. For example when building a house extension ?
Simon.

Use connector bars to the existing brickwork and then altering the
mortar depth to match new to existing.

It's true that an extension badly tied-in look awful. You
can get Imperial sizes - try:

or Google for "Imperial brick" or something. You could use
Furfix, or similar, but the joints still wouldn't match.

has some information, the organisations there may be of
some use.

You tie in every other three courses so that three courses -or to the
nearest brick, go into an hole dug out of the existing wall three
courses or so high. Then you miss three courses then cut out another
three bricks.

Modern brickwork has wider cement bonding than older stuff, perhaps
using imperial bricks, which were put in with narrower gaps between the
bricks.

It should all work out OK. Don't try to get matching bricks unless they
are perfect matches but go for a contrasting colour.
