conservatory build

[climber101]

hi, looking at building a 3x4m approx conservatory (well 'sun lounge' to be precise e.g. tiled roof)

am on the start of my search and will look to buy kit of parts from one of the many places that do same but am interested in ways of doing the base please and pros and cons. I have someone to do the brickwork but happy to do rest myself.

(had a quick search here and notice masona gave a response to this same type query on Tue Feb 22, 2005 8:50 am  with different options but i am not able to open the pictures on that response)
