• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Hi everyone. Going to start off my workshop build thread here. At the moment its still just a design (that keeps evolving!) but I'm collecting materials steadily and hoping to at least get it started this summer.

Our garden is long and thin. About 25mx4.5m. So to keep under 30sqm internal floor area I plan to have a concrete slab of 9mx3.6m at the very end of the garden. That should give me a little bit of working space around each of the three boundary elevations, which to me seems easier than dealing with building up elevations that can never be reached again or lifting fencepanels etc.

Couple of notes:
- I've got planning permission (only needed so I could have a slighlty higher internal height than permitted would allow)
- I plan to clad in non-combustible, use mineralwool insulation & slate roof - all to satisfy the 15-30 sqm building control non combustible part of things.

This is the site plan:

So because its long and narrow, I plan to build based on the original Mikes way design of a single plinth of bricks (i.e. without the blockwork inner). This is because 3 of the elevations wont be visible, so the aesthetics of the cladding lining up dont matter to me as much as the extra width internally. the eaves are 2.3m , ridge height 3.7m.

It will almost certainly change a bit, but here is how its looking right now:

There will be a garage roller shutter drops down infront of the doors. I already have the roller shutter, 2nd hand off ebay. The doors I'm going to have made to fit by a local company once the building is finished.

My first major question is about the concrete slab. (This is the only bit of the build that I rather not do myself, but getting someone to quote to do it for me is much easier said than done!). Based on previous build threads and looking at nearly half the internet I settled on this as adequate for a workshop, but the gremlins always creep in and make me wonder if it needs to be bigger, thicker, stronger!, then the next day I think - nah its more than fine. This design is for 150mm thick slab, thickened to 250mm at the perimeter with mesh throughout and adds up to about 5.8m3 of concrete. So what do people think of that?.

The slab design is fine. The overall design looks great as well.

How wide is your plot?

It’s 4.4m between the fence posts, so a little more at the panels. So 3.6m wide slab should leave me with a slim space to be able to fit down each side to fit the cladding, do any maintenance etc.

I *think* that if you are building within 1m of the boundary, the walls needs a degree of fire resistance.
I built mine to the previous set of regs around 2005.

Worth a check

PS have a look in the forum drop box (link on top right of every page) at the Permitted development guide
There is a flowchart in there about the requirements of the building regs.
 
Yes. I’ll have to use a non combustible cladding for sure. At the moment Im thinking it will be Cedral. But there’s also flame retardant treatments or wood cladding that are rated for class b. Cedral is class a, which is the best rating, but class b counts as non combustible also, as far as I can tell. I’ve thought about cladding in slate too, which I think I would like the look of, but would be a lot of work to do/figure out.
 
If you've got planning permission, surely the external finish has been specified?
 
Looks great.

As regards the cladding - presumably three of the sides will not be visible to you from the garden or house? I have no idea what Cedral costs but it looks very nice and presumably comes pre-painted which will save you quite a bit of time vs painting timber boards, but I used metal cladding on my non-visible wall because it was super cheap and incredibly fast to put up, and obviously non-combustible. It won't look as good as FE boards, but of course if you cannot see it, it is not really an issue. Sorting out the insect mesh is a bit fiddly, but even with that it was a heck of a lot faster to put up the metal clad than all the others!

Similarly, presumably the plinth is only visible from one side? If so, then it will surely be far easier to use concrete blocks rather than bricks for the 3 unseen sides? I hated doing the brickwork for mine: I was rubbish at it, it looked terrible and took forever. But I did the unseen wall in lightweight blocks and it took a fraction of the time that the brick walls took.

You may want to take your time and do a better job than I did, but thought I'd mention the points above as anything to save time (especially on the miserable brickwork) was a big help for me as I had a week to make a useable building.
 
You could use rendaboard on the non seen sides.

Class 0 cement board -its mede for rendering, but it could just be painted maybe.
