Hi all,

I'm considering building as conservatory that incorporates the retaining wall shown in the photos. As it is, it would be a perfect dwarf wall that I could extend to form the rest of it.

Good or bad idea?

Not a good idea. Unlikely the foundations are up to modern requirements or wide enough to support the cavity wall that you ought to be putting in.

As an aside, it'll be tricky making the link from conservatory to existing low roofline look ok
 
Thanks. I'm going to dig and see how deep the foundations go. I'd use the retaining wall as the outer skin if decent enough foundations. The base would be a trapezium and I'd have floor to ceiling brick square columns like an orangery at each corner. These columns would be given deep foundations as they would be supporting the roof. Retaining wall will only take weight of windows.

Yes, I've given a lot of thought to the roof problem. I think I'm going to go flat roof with lantern.
 
There would be a problem with waterproofing having the retaining wall as the outer leaf of a new cavity wall because any water entering the cavity would not be able to dry out with the external ground level being at least 450mm above the floor level of the conservatory.

What about tanking the retaining wall?
 
DMP over covering the all of the retaining wall that meets the cavity? Which would only be 1.7m of the retaining wall.

A lot of retaining walls are meant to allow water to penetrate. Otherwise it increases the load on the wall.
