janelondon Posted May 6, 2019 Share Posted May 6, 2019 Hi all, looking for some advice on insulation for the walls, roof & ceiling for our shepherd's hut side project that we're doing alongside the main build. The aim is to create a well-insulated and comfortable hut to live in while the build's going on. It's a small manageable size (probably 6m x 2.4m) and I'm aiming to do this cost-efficiently by sourcing parts separately from eBay etc. What sort of timber frame make-up / insulation detail should I go for? Current thinking for the walls (external to internal)... - Wriggly tin exterior - Breather membrane - 9mm OSB? - Timber stud with 90mm frametherm insulation - VCL - 35mm service cavity batten - Plasterboard wall Does this make sense? Is it overkill? Can I replicate this for the curved ceiling & floor? Thank you. Link to comment Share on other sites More sharing options...
nod Posted May 6, 2019 Share Posted May 6, 2019 Quite a few on here have lived in static caravans Might be a bit more comfy than a shed Link to comment Share on other sites More sharing options...

We've looked into the off-the-rack huts and they can be very nice and comfy! But fancy the challenge of piecing it together ourselves... Famous last words.

Temp Posted May 6, 2019 Share Posted May 6, 2019 Tin roof sheds can get very hot in summer. Not sure what to recommend. My shed stays impressively cool but it's got a concrete floor and tiled roof. Walls are oak boards, air gap, membrane, WBP, studwork filled with cheap loft insulation, more WPB. 1 Link to comment Share on other sites More sharing options...
Russell griffiths Posted May 6, 2019 Share Posted May 6, 2019 I would think with that level of insulation it would only be any good for living in in the summer, wood burner needed for winter. 1 Link to comment Share on other sites More sharing options...
joe90 Posted May 6, 2019 Share Posted May 6, 2019 Very timely thread as a am planning a Shepard’s hut fir our meadow now the house is nearly finished. @janelondon you don’t need planning if it has wheels and can be moved (even with a crane) as it is classed as temporary. We hope to use it as a counselling room fir my wife’s business and drinky poos in the summer. I did find a neat small woodburner on Ebay https://www.ebay.co.uk/itm/Small-Coal-Wood-Burner-stove-heater-BOAT-CAMPER-YURT-SHEPHERDS-HUT-SHED-MAN-CAVE/132514653615 I was worried about condensation and thought similar to Jane on the wall build up, but using tongue and groove to line the inside. I like @SteamyTea curved I beam but won’t be parking a car on the roof so feel safe with that one. Link to comment Share on other sites More sharing options...
janelondon Posted May 6, 2019 Author Share Posted May 6, 2019 Yes - def planning for a woodburner. Thanks for that link @joe90! What size hut are you going for and how are you planning to build? I'm most likely ordering the chassis from a local steel fabricator and getting timber from a local merchant to stick-build. Apart from condensation, another concern (valid?) is noise on the tin roof when raining. I researched a lot into the usual £££ hut makers (Plankbridge, Blackdown etc.) to look at their construction and also asked them about noise and they've said it's not a factor... I'm thinking of putting a bit more insulation into the roof to counter that. Link to comment Share on other sites More sharing options...
Roundtuit Posted May 6, 2019 Share Posted May 6, 2019 Hi. Don't know what your situation is re: build route, but you should consider whether a 'side project' is really going to be a realistic option if you're going to be anything like hands-on through the build. If you need it fully plumbed and wired, then +1 for the static caravan option. Live in it for the duration of the build, then sell it to finance your dream shepherds hut if it's still on your wish list! Link to comment Share on other sites More sharing options...
janelondon Posted May 6, 2019 Author Share Posted May 6, 2019 Fair point @Roundtuitbut our main build won't be starting until end of this year. We won't be doing all the work ourselves but will be sourcing materials. We live 100 miles from the site so the hut will actually be for us to stay in each time we are on site to save on hotel costs. Thought it's also a good opportunity to get to grips with a mini build. ? Link to comment Share on other sites More sharing options...
Roundtuit Posted May 6, 2019 Share Posted May 6, 2019 Ok, you've got a bit of planning time then! If it's just for short duration site visits (assuming you have some services on site), then anything better than a tent is a bonus. My view would be to keep it simple, ventilate well, and light the wood burner when it's chilly. 1 Link to comment Share on other sites More sharing options...

Not got that far yet but I have already bought a set of cast iron wheels, probably all timber and not too big as we don’t need to sleep in it, just a garden room on wheels with character. With our site I bought an old static to live in (on my own as er indoors still working 130 miles away) . Link to comment Share on other sites More sharing options...
PeterW Posted May 7, 2019 Share Posted May 7, 2019 Curved wavy tin comes in standard widths - double check that your design uses these and you will keep the costs down. 2 Link to comment Share on other sites More sharing options...

Assuming mains is available that really shouldn't be a problem for ocassional use. Edited May 7, 2019 by Ed Davies 90m of Frametherm → 90mm. 90m would, indeed, be comfy. 2 Link to comment Share on other sites More sharing options...
joe90 Posted May 7, 2019 Share Posted May 7, 2019 Yes a static has very little insulation and loads of ventilation (ask me how I know?) but fairly easy to heat and costs a lot less than renting. Link to comment Share on other sites More sharing options...
ProDave Posted May 7, 2019 Share Posted May 7, 2019 We put a 4KW WBS in out static and that was okay over winter but you do need to keep it going. Keeping up the wood supply was a bit of a challenge and we burned coal overnight as that would just about stay in over night. Link to comment Share on other sites More sharing options...

joe90 Posted May 7, 2019 Share Posted May 7, 2019 Ha, just noticed that I said above I was going to put the Shepard’s hut in the “meadow” currently it’s a muddy morass due to years of neglect from the previous tenant, WE have discussed OUR plans to turn it into a pleasant meadow to compliment the cottage that I have just built. Ratty. Link to comment Share on other sites More sharing options...
