• 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 guys

I started messing about with sketchup yesterday to plan out my workshop build.

All images and the sketchup file are here https://dl.dropboxusercontent.com/u/26593756/workshop_build_1.skp

Would you mind having a look and letting me know if I am going in the right direction or if you would change anything?

The build is going to be a 12x10 pent roof workshop.

https://dl.dropboxusercontent.com/u/26593756/workshop_build_1.jpg

With it being positioned close to the boundary wall, it's maximum height is 2.5m. It's going to sit on a plastic frame, with pea gravel all over. http://www.simplygardenbuildings.co.uk/probase-shed-base-foundation-569-offer-9222-p.asp. The reason it to keep costs down and the amount of work to get a concrete base in position, is both hard work and 3x more expensive :(

I designed it so the frame is built using 4x2's, however if you think I can get away with 3x2's please let me know.

The floor joists will constructed using 45mm x 95mm decking joists, with insulation throughout and re-enforced with 4 cross braces

And then insulated with some 75mm Kingspan

Then covered with 15mm WBP plywood

This is as far as I've gotten, and my first time designing something like this, so I might have gone a bit overboard or missed something.

Primarily the workshop will be used for woodworking, so will have the usual's (Bandsaw, Lathe, Workbench, table top pillar drill, scroll saw and a small construction tablesaw)

Many thanks in advance

Gareth
 
Gareth, unfortunately it would seem that Goggle Drive does not allow the embedding of images. I know nothing about Google Drive but I quick search indicates that the image permissions must be set to "public" and be deposited into a "public" folder. Is this the case for the 3 images that you have tried to embed?
 
Mike G, our resident architect swears by timber frame building on top of plinth brick/block walls. He regards this as essential for long life of the timberwork.

Mike will be busy building his house in daylight ours but could well be along later this evening.

Your base system is totally incompatible with building such a plinth and from the website it does not look like it stands very high above the ground - which is the key to stopping rot.
I can understand the attraction of not having concrete base but you should be aware of the downsides of the effect on the timber frame.

With regard to the jpgs. You are probably best storing them on a site like Photobucket where we know the forum software will display them.

Reading threads which simply comprise links to other sites is both hard work and against the ethos of the site
I realise that you did try to post diagrams in good faith so this is not a dig at you Gareth

Cheers

Hi Andy

Thanks for that, I've moved the images over to my dropbox share and the images are now displaying.

:)

Hi 9fingers, Thanks for the info, the amendments I made now display the images.

How far off the ground should the timber be to not be affected by rot?

Thanks

Gareth

Welcome!

Mike advocates a wall at least two bricks high to separate timber from ground, with DPC between the two. In his recent build he went three high, if I recall for aesthetic reasons. I strongly recommend that you skim the first few pages of the 'stickied' thread at the top of the projects board.

I made a relatively small foundation for my shed outline (something like 300mm x 300mm maybe less in places) and built a wall on it 2 bricks high. The shed is built on top of that wall. 100 x 50 timbers for the floor with 18mm shuttering ply on top as the floor. No rot so far after about 8 years.

The ground slopes so while in places the wood is 2 bricks above ground, at the highest ground level the wood is only 2 inches above ground but is still sound. I'm no expert but as to how far off ground anything is better than nothing. can't imagine that mesh stuff you linked to working long term unless it is on a cement floor to stop it sinking in.
