The oven has a heat-resistant base, but you need to build a raised support platform of limestone, concrete or bricks. This one has a 100mm-thick concrete slab with three walls of Hebel autoclaved aerated concrete (AAC) blocks. Steel lintels span the walls to support Hebel floor panels.
How to Build the support platform
Build the support base
Pour a concrete base with F52 reinforcing mesh, measuring 1800 x 1800mm and 100mm thick. Leave it to dry, then lay the three walls of the base using four rows of 600 x 200 x 100mm ACC blocks.
Attach the front
Cut a crossbeam and two uprights from railway sleepers. Secure the uprights to the base with metal angle brackets. Position the crossbeam to be level with the tiles that are put down later, securing to the uprights and panels with angle brackets.
Add lintels and panels
Cut four 75 x 50mm-wide notches at 30mm deep on the inside of the walls to hold two steel lintels. Position the lintels so the ACC panels meet on the centre-line, securing with adhesive and screws.

Hi Tracy, your best bet would be to contact a local concrete manufacturer and ask about the availability of autoclaved aerated concrete (AAC), which is the generic term for this product. We have tried to find a South African distributor for Xella, which is the international umbrella company responsible for Hebel, but to no avail. Another option would be to contact Hebel USA directly (hebel-usa.com) and ask them to recommend a local retailer. Hope this helps. -RD Editor

I've always wanted to build an outdoor oven. Where can I purchase the cast-iron door in South Africa?
