Round window in existing wall

A big Core drill! :^O

 

go to a hole saler lol.

 

would have thought this would be fairly simple
get window made by Double glazing shop ( makes it their problem to get it right)
put a lintel above it to support the wall above ( if required)
draw a circle on the wall, to take window, drill round the outside with 13mm drill making loads of holes
join holes with club hmmer & chisel / SDS drill
fit window, make good

 

These people might be able to help.

Let us know if they can or can't.
