I had to fit in between the garage and the boundary fence and keeping it under 2.5m high from the highest ground point and under 15m Sq floor space and trying to minimise waste on timber using 4”x2” ( 100mm x 50mm ) framing, it was 2.4m wide and 4.4m long externally if I’m remembering correctly ?
Had to prefabricate the long side panels then lift into place, they are clad in bitumen corrigated sheets . The roof is a rubber membrane the house facing front is feather-board cheap on sale from Selco as are the barn doors . Done the leccy run then got a neighbour to check and sign off and certify . Lights and sockets Screwfix . Internal walls and ceiling 9mm OSB, three coats of acrylic latex primer then three coats of non porous Centrecoat Aqua Anti Bacterial Hygeine paint, designed for food prep areas hospitals etc , if had a bigger budget then I would of went for hygeine cladding boards but I didn’t so researched and found this, used food safe sealants throughout and a food safe curtain to separate the two rooms . Tried a food safe epoxy resin floor paint that was suitable to go straight onto OSB floor after chatting with their technical department but it was a nightmare as it goes off really quick and I wasn’t happy with the coverage.
Managed to find catering Lino on sale so went with that, fairly happy will be happier when the chiller has some Fallow in it
