I am in the middle of building an Eco/Energy efficient house in S.Wales. The owner wants me to incrperate a housed Pompeii oven/grill station using the stone which was excavated from the house. I would like to build something like Pete's ("burning pizzas in Surrey")..stone housed Vault oven.... At the moment I only have this....(the owner Rob at the helm of the mini-digger) Rob is trying to use all the stone from the house excavations to use somewhere on his property (which will be called Fordell House) ...The oven will be incorporated into a contuation of this "wet" natural stone wall at the rear of the house... Typical brickies shuttering (concrete blocks laid flat to form the shape of the curved wall where the oven will be incorporated (Luke, the other bricklayer helping me on this project).... Our stone pile. We must "pick the bones" out of this lot for our building materials.... If you click to enlarge the above pic, you will see the task ahead....the larger stones weigh well over a ton. The rest of the stone will be used to face the front facade of the building and finish off the dry stone wall to the front of the property... ....fingers crossed for some dry weather Terry

Hi terry
Looks like you'll be busy with this one for a while! Nice job! Glad to see there's some work down there, we have a few jobs on the go but there's nothing else coming in. Did you suggest to your client they incorporate aan oven into the job? How many ovens have you built?

Work is very tight here in S.Wales and I always seem to be struggling to get a full week in. I have been working on this job for about 2 years. The owner is doing this job in stages. At first we built the basement (and swimming pool within the basement) with the Eco system "Logix blox"....what a pain that was. From the ground floor, it was timer framed. I was then called back to create a sandstone plinth and lay concrete blockwork to the sides and back.Sandstone sills and lintels were also laid. These were finished in K-Rend. The front of the house will eventually built with "dressed" stone....cut from the "pile"......over this time the customer has learned of my hobby......and now....he wants one.
I've built about a dozen ovens.....mainly for friends and local communities. Most of these have been Pompeii ovens, the rest have been Clay/Cob. I learned a lot from my first Pompeii oven....not enough insulation under the hearth....and over the dome.....It's my own oven......a re-build is long overdue.

Update.... Wall line formed.. Log store set out... Log store ready to take arch.....once the arch is laid, the shuttering will be put in place.... BBQ area set out. The right hand side of the housing for the oven will sit on top of the finished height of the left wall of the BBQ. This is "end of play" today. Tomorrow comes the wood-store arch, then the stone can be brought up to finished hearth level, the slab shuttering can then be cut to the rear of the arched stonework so as the poured concrete slab can be laid ....on top of the concrete blocks ....AND up to the rear of the stonework above the arch.......bit complicated with the BBQ .....but I'm sure I'll figure it out. terry

Cheers Danno......I'll never tire of a bit of encouragement. Log store formed and concrete slab poured... Attachments:

That's a lovely looking arch - I bet the whole oven is going to look fantastic.

Thanks Faz......it's not all plain sailing though. I've hit a few sags....I haven't quite got enough depth so I may have to put in another footing to the rear of the slab if I want to put a housing around the oven. I also built the BBQ too close to the oven. The slate roof of the housing will let the rain fall directly onto the BBQ area....unless I put some guttering up. Also need to install a drainage system to take any water build up away from the oven and grill and direct it to weep holes either side.
.....I'm sure I'll get there in the end. Sometimes you just have to "switch off" from thinking 4 or 5 steps ahead......I never was any good at chess!!

You cut your hair Terry?
I always like an extended roof. Could you send the RH Side of the roof out over the BBQ to give it some cover too? Just a thought, and i expect you'll come up with something that works anyway.

I had thought of that but the roof trusses that would have to overhang the BBQ area to create this, would be subject to direct heat from the BBQ. I thought a piece of fire-board used as a soffit may protect the trusses but I'm not so sure on this. I'm trying to envisage the finished result...but I'm having problems staring that far into the future....
I appreciate your thoughts....and keep em coming.....I don't want to blow my own trumpet, but I'm good with bricks and mortar so anything is possible.(virtually anything). The owner is having a grill/griddle fabricated this week-end so I can finish the r/h side of the BBQ to incorporate the grill tray dimensions. I may then be able to post a pic of the whole "set-up" and then pester you again for your thoughts. (your thoughts on my little conundrum will be appreciated...and your posts on the forum are always well received).

What about building the BBQ structure so that it incorporates a roof/chimney, like the one below. It's a bit more work but might be an option.

Update... Had a delayed delivery so I had the chance today to have a well earned rest from laying concrete blocks and jump back on the oven.... The cal-cil board from Liam was trussed up like a turkey at Christmas as per Liams instructions (wrapped in silver foil)....... Bedded it down on some normal mortar..... THE MORTAR......I'm going to stretch the mix on this build to 6:1:1:1....I think this is a lot stronger than the recommeded 4:1:1:1....time will tell!!. Top left.....Powdered fire clay.....Top right...hydrated lime.....below normal cement (opc).. Luke...setting out the first ring..."half" brick-on-edge... "sponging off" the the first ring after the diagonal herringbone fire-brick hearth has been laid... Worked out my % height of the internal arch. Dry laying the arch bricks and marking where they must be laid..... I pre-cut the back of the arch bricks ready for the dome/arch transition.........This is usually done "as you build" when using a jig...or "the indispensable tool".....I'm using a removable form so I have guessed the cuts on the back of the arch bricks. It's bricks and mortar so I will "encourage" my dome courses to meet the cuts at the transition (don't ever be afraid off veering from the perfect circle when making the dome/arch transition)....you normally have to literally go a bit "pear shaped" on your dome to make this transition..... I needed more of my "dome former fins"...but didn't have my jig-saw with me to cut what was needed so I used the rest of the homebrew already mixed up to build the BBQ......I moved it from it's original location to about 80cm away from the wood-fired oven. End of play today..... Tomorrow my belated delivery will arrive so I'm back on building the wood-pellet room (priority) .....laying concrete blocks...on flat....Oh bugger... Terry EDIT......note the different shade of the hearth bricks around the edge of the hearth.....these bricks were soaked in water, making them easier to cut........and saving the life of my diamond blade.....

Update.. (helper is Luke. A decent lad...when he turns up!) Due to a NON delivery ...had to work on the oven without camera at hand, but built up to the dome/arch transition using my form fins technique. (pic from a previous build).... So I'm up to this stage..... ....sorry about image sizes....having probs..... This is a view of the full course over the vent/dome transition. I then put back in my dome formers and laid some cardboard over the formers to hold the sand which created the form to lay my last few courses and capping stones.... ...I then used quarters....halves cut in half....then a course of 1" fire bricks...again cut in half......and then cut once more... ....and here is my combination of Cap stones...... Here is the view from underneath...... .....as my "mate" didn't turn up I was up and down like a blue arsed fly and the top of the dome wasn't as good as I like it to be (ridges between the courses, although I used a wet sponge to soften any sharp edges) Tommorow I shall build the external arch which will allow me to then apply the thermal blanket. I can then start to build my stone housing around the structure. I would have normally already have my external arch built ....thus allowing me to have already started my curing fires......things don't always go to plan... Terry
