Mike's ext'n & renovation (sunroom stone floor & plinth)

This is where we don't want anything but evidence of your finest wood butchering in all its glorious, and photograph laden glory. Bring your finished products or WIP's, we love them all, so long as there's pictures, and plenty of 'em!

This is a big moment in any project:

Image

But what sort of madness is this, Mike?

Image

Image

It looks suspicously like the front form is an inch lower than the side form, with some sort of oddity in the corner. And then a string line across the concrete! What's that all about?

Tamped, and with our tame blackbird doing a preliminary inspection:

Image

Image

Here's that corner again:

Image

With the cartlodge being open, I always slope the first 900mm or 1m, so that driven rain will flow out easily. It doesn't need to be sloped under the plinth, though, hence the little step. I compensated under the slab with a little extra digging, so the concrete thickness stays the same.

I pulled a stiff broom across the surface a few hours later:

I really am in awe of the amount of energy that you have Mike, but I think you ought to be careful when you finish it all – what an earth are you going to do with your time?
I’m guessing you set light to the shavings to burn off the grass?

I get worn out just keeping up with his build threads :)
I do not think therefore I do not am.

I've got years of furniture making lined up for here, and there's a caravan to build. I'll find a way to stay busy.

Minus three forecast for tonight, which is not great with new concrete. So, I've just now put down a layer of polythene over the whole slab, then piled anything I could find on top which might act as insulation:

Good start. I always like to get to that stage, as everything is much cleaner after this. Hope it doesn't freeze on you.

Shavings make good insulation, oh no sorry lol. It would be a shame to damage that new service. Mike

Whats the plan for driveway surfacing Mike? When doing mine when we moved here, we had about four inches depth of loose shingle, laid on mud, and I ended up removing the lot (used for drainage ditches) a lot of type one, rolled in, then a lot of limestone, also rolled in except where we put the block paving. Looks like your access is really easy.

Access is a doddle. There's a crazy-paving surface down at the moment, which I am planning to break up but leave in situ, then make up the levels with some Type 1, then shingle (18mm stone). It crossed my mind to do that this weekend, but I have a dodgy back to nurse, so I thought a day on other tasks after the heavyish work of concreting (is there any noun which can't be verbed? :) ) might be sensible.

It looks like the layers of stuff did their job properly. All is well this morning, and there is quite a lot of moisture (liquid) on the underside of the polythene. It'll stay covered for a day or two as I think we haven't seen the last of the frost just yet.

Is it a "peg" showing the level of the top of the plinth, so you can span across from the battens to the wall with your biggest level?
It's in the middle to keep it out of the way of errant dogs, bricks, gongoozlers, bricklayers etc.

Matt wins the internet points. :eusa-clap: :eusa-clap:

I haven't got a working Dumpy level or laser, and the longest straight edge I've got was under half the span of the slab. So to be able to chuck levels all around the job I needed a level something in the middle onto which I could rest the end whilst taking level measurements and then putting marks around my height posts at each corner.

Re: Mike's extension & renovation (garage framing done)

Postby Mike G » 24 Apr 2021, 18:44

Having finished the brickwork, I then ran a course of 50mm blocks around the inside of that:

Image

Image

With 3 scarfs, corner lap joints, and two dovetails to cut, fitting the sole plate took far longer than you'd imagine. It also needed housing out for the straps, and a DPC stapled to the underside, before finally bedding it on a generous bed of sloppy muck:

Image

Image

Image

Image

The dovetails are to support and retain the bottom end of the oak corner posts. Housing out the end-grain of those is hard going.....but I don't even have the wood yet.

I set up a bench:

Image

....and with the nail gun and chop saw, making the frame was a pretty easy day's work:

Image

Image

Image

Image

The astute may have noticed the stud spacings vary. The back wall will be bearing a roof (clay plain tiles) so I have the studs at 400 centres and a double wall plate. The gable walls don't take any load other than down through the obvious posts, so they are at 600 centres.

I take it you’ll require a substantial purlin where the rear roof changes pitch hence the multiple vertical timbers on the sides at that location?

That's going to be a flitch beam, made up of a pair of 9x2 timbers sandwiching a 15mmx200mm piece of steel plate, 6 metres long. Lifting that into place is going to be fun.

I’ve lifted similar in the house. Perfectly doable with some advanced planing. Good luck
