We are thinking of puting some glass bricks into an internal single brick 
supporting wall possibly 5 bricks wide by 10 bricks tall.  This would bring 
in some welcome light into a dark windowless narrow hallway.

As stated the wall is a supporting wall for the flat above (we live in a 
block of 4 ie 2 flats  across and 2 flats up) and we are a bit unsure what 
type of support would be needed.  Would a concrete lintel be enough or would 
we require an RSJ.  We are reasonable competent with regards to DIY but we 
were wondering how easy these bricks were to install or should we leave it 
to the experts?!

Any help/tips etc appreciated :)

Thanks in advance
