Ive just been given the green light by the boss (you know who I mean!) to build a workshop. I’m going to put it up inside a portal steel framed shed that was previously a cow shed here in Derbyshire UK. I was thinking of using 4″ concrete blocks with a ‘lining’ of 4″x2″ timbers to contain some Rockwool type material and then boarded over with ply or similar. I’m trying to keep the warmth in you see when I heat it but also a decent structure to which I can attach rack and cupboards etc. Any thoughts on this guys?
Also, being predominantly a hand tool person I will probably only have a band saw in use at all regularly but might make occasional use of a table saw and possibly a planer/thicknesser (dare I say it?) Do any of you guys know of any good reference material on workshop design and layout?

Well John i’m very jealous that makes my 9′ x14′ drafty shed sound like a dog kennel good luck with the build keep us posted with pics and updates

I take it you building a shed in a shed?
If you use 4″/100mm Celcon blocks you would have better U value and by putting 4″ stud work and 4″/100mm Rockwall should help keeping warmth in and heat out in summer. If use Celcon block and face the elements you will need to render with sand and cement with water proofer mix.Even if you use concrete blocks still best to render even concrete blocks hold moister. Do not forget to insulate the roof space other wise wasting time. Also put a few air bricks in or have trickle vents in windows installed this will help with condensation will help stop rot meldue etc. Ply would be best but if not to fussy about look Oriented Stirling Board OSB would be a cheaper option.
Also if have concrete floor may be worth putting some ply down on battens on top.
It is nicer to work on a timber floor warmer and not as hard on feet. If no concrete floor just install floor joist on some sleeper walls or use joist hangers.
The layout depends on size but it is nice to have a bench off the wall. If bench on the wall you restrict yourself size of projects. Nice to be able to get all round a bench.
if using machines remember to allow for feed in and feed out I would allow a min of 4′

Thanks guys, will do some photos and updates as I go along.
Mark, thanks very much for the info. Never heard of Celcon blocks. Had thought of using thermalites. Are they at all similar? Good call on the ventilation suggestions, will certainly put some vents in and I like the idea of standing on ply instead of concrete.9 January 2014 at 10:23 pm #25629Mark ArmstrongParticipant
Celcon and Thermalites are all most identical. You can get different densities and U value blocks. I think you can get 7 tonne which are better more structural purpose say a jack wall that has to hold quite a hefty a RSJ or 3.5 tonne which I would think would serve you better don’t quote me on exact densities don’t think I’m far off though.
Also don’t forget your Damp Prevention course DPM in block work. Also is you have a concrete floor and going cover it with ply you could use a Damp Proof Membrane visqueen plastic barrier or what I know as black jack a black rubberised tar solution you brush over the concrete floor. I can’t think of it’s proper name it comes in 25 litre containers.
I’m a chippy by trade but I have done a fair bit of bricklaying and Plastering in my time.

Fantastic Mark thanks for all the pointers. There wont be any weather getting at the walls but it will be sat on a concrete floor that is without insulation or dpm under it so yes i think your suggestions will be needed. Cheers
