Hi all
Question if you please.
Is stepped blockwork on a top-half tile hung house common? We are tying into existing (not a builder) and the blockwork is stepped to accomodate the hung tiles. It causes us a problem because its b*ggered up where our g/f blockwork is (laid out by the sacked builder).
Pic enclosed - comments appreciated. Ta.

yes, it is common on older properties
the downstairs might be 250mm cavity ,then upstairs is 215 brick or blockwork ,then buy the time you tilehang it you add 75mm so it becomes 290 mm and overhangs the downstairs
we did one last year though and all the new block work was the same from top to bottom
you just have 75mm tilt fillet at the bottom to accomadate the first row of eaves tiles
hope this helps

Typical, it never rains but it pours. The stepped blockwork is all flat-laid blocks ie no cavity. Can't believe I never spotted it straight away. Bet if it had been at a client's house I would have sussed it from the other end of the garden!!! It was above a kitchen and only supported the sloping ff to gf roof over. We are building it up "square" to stick a hip-gabled proper bedroom over instead of the crappy dormer that was there prevously, but of course it needs a cavity so looks like it will be coming down (at least on one side - the other side will become internal. The irony is that the house is single skin anyway - it's an 8" belgian solid brick then dry lined with asbestolux-type board (now plasterboarded and skimmed to encapsulate). So we have no real cavity anyway...
Hey ho, we'll see what the building inspector has to say tomorrow......in retrospect it might be worth just taking both sides down, saves the bonding of flatties with normal blockwork at the front.....
