After my builder hasn't showed for the 3rd time again without as much as a call I'm contemplating tackling the job myself and looking for some advice.
Background: We had an L shaped extension put onto our house (back and side) by previous occupiers. We want to knock through a door way through the old external wall and into the new extension. I've had a look at a few sites and the process seems relatively simple for a straight forward wall.
Problem: If I use 2 acrows with strong boys, how do the strong boys fit right through the cavity to reach the inner line of bricks considering the strong boys are only 150mm in depth yet the double skinned wall is 310mm?
Another problem is because I have to work from the extension in towards the house and don't have access the other way, how could I possibly fit the lintels if the acrows / strong boys are hard against the wall?
Even if the builder does turn up I'd be really curious to know how it is done.
Any advice would be great.
