Once they are rendered off inside and out you will need a sledge hammer.

I did want to catch a picture before they done the beams, still they haven't started on the fronts of the other block yet.

So what's happening here we ask ourselves? This is the entrance or exit to, from the balconey, first up they lay the bricks upto where the height of the glass work will go, drill some holes and chuck in some rebar, stick a form round it and then pour the concrete to make the beam, leave the form work in and then brick up to the top where one of the main beams are.
