One of Tim Daw's excellent photos from his "Neolithic" burial chamber at All Cannings. There is a whole gallery of photos here:
and here we have much more info about Tim's project:
This is another nice illustration of the way in which the seven chambers are being constructed:
The technique is not quite "dry stone corbelling" because there is a lot of concrete used, out of sight, on the outside of each dome. The flattish stone slabs are also much more standardised in shape and size than those used in corbelled chambers constructed in the Neolithic. Health and safety, and cost, have obviously had an influence on the methods used by the builders....... But it's great to see this piece of engineering skill being used again, and for a practical purpose.
For comparison, here are some other corbelled chambers:
