Cavity Blocks for building shed

    Hi folks,

    I want to build a shed to house some motorbikes and somewhere I can use as a workshop/man cave :D the emphasis on the project is cheap & secure. I was planning to go 12 ft x 16 ft. Now would cavity blocks be ok for the build?

    If i insualte the base and roof enough (pent roof) would the cavity blocks be enough. I can always dry line the inside in the future for the cold months :rolleyes: I don't want windows as there will be alot of tools (kettle:p) in shed and the bikes themselves, just secure double doors on the front. the garden walls a brick finish so for the shed was thinkin 4 independent walls with just the brick finish. I won't be hanging anything too heavy on the walls as my workbench will be freestanding.

    Thanks, any advice appreciated.

    Cavity blocks are fine for a shed - hey a lot of people are living in houses built with these!
    The important thing though is getting a good waterproof render/plaster finish on the outside, and good detailing at your roof/ eaves areas, to prevent water ingress.

    sound, is rendering expensive ? and what would be best for roof material, metal cladding, felt or tiles ?

    Render won't cost much, but should take a plasterer two visits - first for scratch coat, second for final coat. He'll need cement and plastering sand on site for him, presume water will be readily available.

    Re roof - best depends on what way you are building....
    If you can, then a good pitched roof with slates and tiles is best, but this is more expensive.
    Sheeted corrugated on felt is probably cheapest, and quickest, and again fine for a shed. It's also easy to fit a translucent panel with corrugated to let some light in. Very easily a DIY job (Roofing it)

    Rendering is just plastering sand, Portland cement, Lime and waterproofing plasticiser. Not expensive.

    I did a similar build a few years ago and mirrored the tiles on the house roof with a Velux on each side of the roof (same as you didn't want windows). I was able to do it all myself and materials came in around €1,000 - €1,200

    Even though its just a shed planning is key. Before you dig the first sod make sure its big enough nothing worse than finding out the place is too small to work on a bike comfortably unless you put everything else out in the back garden.

    Make sure you have sufficient foundations dont be tempted to skimp, seperate electric supply with fuse board in shed so you can split out lights/sockets, proper DPC for base and walls with floor insulation, dry line and roof insulation, good lighting and a big ole armchair preferably a recliner :)

    P.S. intercom or bell so missus can call you is a definate no no :D

    Tbh, I wouldn't use cavity blocks - if, like me you spend time in the garage (bikes here too :) ), you want something warm. 9" cavity block is useless. And, you don't want stuff condensating and rusting.

    But it's all down to price - if you're not building from a 'warm' material, then build a cavity wall and pump it.

    People not in to garages will think that mad - if you spend half as much time in it as I do, you'll want it to be comfortable. My existing garage is in the pic, and it has pump walls and composite panel roof. It's warmer than most houses - and still just about o.k.

    Build it once, and build it right.

    I must agree with galwaytt here, you get one chance to do it right and using cavity blocks just won't do it. They will only make it feel damp and the walls will suck moisture in during heavy rains. A pumped cavity works well.

    Nice Road King, btw galwaytt, if I'm right you sold it recently?

    Have to agree with the last couple of posts. Opt for a conventional cavity wall and decide what you want to do in relation to insulation.

    Noooooooooooooo.....I'd never sell it !! I luv it :D

    I've sold that stupid quad since, though (frickin' chinese junk.......)

    Meanwhile, back o/t: my garage space above is 13m x 8m, with a mezzanine over half of it. Was wondering about heating it: is there such a thing as a self-contained heater/blower, unit, kind of like those large ones you'd see in a............furniture shop.........a large 600 x 600 'radiator' w/fan....but with integral heater/burner....?.....but I don't want a separate boiler, piping and tanks. I don't want a kersone blower unit.....(fire risk).

    Not being funny but those are ideal conditions for a stove.
