It's too late now, but here it is.

I spent about 2 hours tonight watching Google Sketchup howto videos and here's what I've got to show for it.



The kitchen is intended to be 2m deep and 2.5m wide. Making it too small to worry the planning authorities, but hopefully big enough to satisfy the CFA to let us have a fire in it during fire season, if not total fire ban days.

The white wall just in front of the raised hearth is the ingle nook. Hopefully the smoke goes behind that into the roof space and out of the hole at the top of the gable end.

A later design will find a clever way to put an oven on one side, with the opening in the kitchen, under the inglenook.

Don't look too hard at the pictures. The inglenook is currently held up by skyhooks.

The roof tiles are unlikely to look that pretty - they might look more like these

Edited to add some stuff this morning

I forgot to mention that we could increase the depth of the building to have room for a prep table in the front, out of the weather.

Also, the firewall should probably face Northwest, to shade the occupant from the summer sun, particularly in the afternoon.

And I left out the daylight windows either side of the firewall.

The list of materials I'm imagining would be useful includes:

-bricks for the hearth (and more for the oven)
-bricks or suitable stones (not concrete block) for the firewall at the back
-withies for the inside of the wattle and daub
-mud and straw, maybe charcoal, for the daub
-trees at least 150mm diameter and 2m tall, with forks in the right place, for the corner posts
-150mm branches that are straightish for the beams; 3 x 2.5ish metres and 3 x the ultimate depth of this shack.
-roof tiles
- more free weekends - Sunday 19th October anyone?

I'll keep an eye out for sky hooks at garage sales, shall I? ;-)

I almost certainly know less than you abut how chimneys work, however, I recall seeing something that said they work due to a pressure differential between the out side and the inside of the building. I am wondering if this building is enclosed enough to provide this? Or will the heat from the fire make the smoke go where we want it to? I do know a warm chimney draws better.

[celsa.livejournal.com]

From my stance of confessed ignorance, I think that's a good point.

I wonder whether it would be period appropriate to attach a temporary canvas awning (possibilities ranging from a small sunshade to a substantially enclosed room) to the open side of the building when in use, with a view to providing the enclosure you describe? It could be opened and closed as required to tune the draw of the chimney depending on the weather.

I don;t think that attaching a temporary structure to a permanent one would draw the ire of the council, would it?

[doushkasmum.livejournal.com]

I think my mental image had the gable ends filled in on both ends, which would at least give an enclosed roof space.

[celsa.livejournal.com]

Hmm. The space thus enclosed would be higher than the inglenook. I don't see how a pressure difference adjacent to but separated from the inglenook would help the chimney to draw.

[doushkasmum.livejournal.com]

I am not sure either. Hmmmm

[mrsbrown.livejournal.com]

The heat from the fire will send the smoke up the space between the inglenook and the external wall.

The heat will provide the pressure differential you are talking about.

Um, the draw of the chimney of the open fireplace in our house was improved greatly by adding a cowl on top that span in the wind to ensure the bit where the smoke came out was facing away from the wind. It also reduced drafts when the fire was low. What I guess I'm asking is, should the building orientated with reference to local wind patterns?

How big will the council let a kitchen be before regulations apply? Could you have a nice wattle & daub annex? Or if not, does a roof and supporting posts only structure count in their regulations? Temporary wattle or canvas walls could be slotted in.

I note you're not using dung in your daub.

[mrsbrown.livejournal.com]

Planning regulations don't apply to buildings smaller than 3m x 3m.

Hence the suggested size of 2.5m wide and 3m deep. Yes, we could probably attach a canvas structure for more space.

Yes, local wind patterns could affect the smoke coming out of the gable end, and should be considered.

Can you estimate the quantity of bricks required? Is that a double-layer of bricks in that wall?

I may be able to locate some suitable second hand bricks. Stone would be nice, and may be able to be scavenged pretty simply. I'll look out for timber and other materials, too. What kind of mortar were you thinking of using if bricks were to be used? Any?

What kind of fastening methods would be used for the timberwork?

Sunday October 19th is the day after the dancing/ball event, but that shouldn't be a terrible hinderance. I intend to participate in both. :-)

[mrsbrown.livejournal.com]

I was imagining a single layer of bricks.

The brick area required is 2.5m wide and 2m high. Mortar's good, probably made with cement, sand and water.

I'd prefer pinned mortice and tenon if we could manage it.

I don't expect to get much done on the Sunday, but it's important to spend a suitable amount of time wandering around saying, "hmmm". It'll make it faster the next time we start work.

Why trees as posts?

Wouldn't cut timber be better? And evem more period appropriate?

Correct me if I'm wrong, cause I really don't know.

[celsa.livejournal.com]

I'm also curious, as I do have some very handy looking sawn timber beams to hand here.

Also I can't think where anyone could legally obtain appropriately forked trees, and if they did go out and cut them, they would require time to dry/season/mature into usefulness, yes? It's all very interesting. :-)
