Hi,
I'm currently costing a diy conservatory before deciding on go ahead.
The problem I have is that the ground level between the house floor level and outside patio level is a 500mm drop. Other problems I have which would be rectified by raising outside floor level (which I will ask about later) is a large patio door already in place (which will give access to conservatory) plus a boiler flue (which cannot be moved) and also a flat roof!
The conservatory planners have taken all this into account and come up with a size and type (hip with boxed gutter) that will overcome these issues. However that leaves one problem for me..................the ouside ground level needs raising:-
My question would be this:
The patio already in place (500mm below building floor level) has concrete base to a depth of 400mm onto clay. Can the patio slabs be removed and the base for the conservatory be built up from the original patio base? Or do I need to dig through patio base down to clay and add new footings for conservatory?
Any help appreciated. Been researching for two days now, still none the wiser. I've spoke to two builders one saying it would be ok to build up from current patio base but another saying to dig out new footings......what to do?
BTW Conservatory would be dwarf walled 4000 x 4975 with glass roof.
