Shed Build

[TheRamJam]

Hey folks,

Finally after 8 months of searching we have an offer accepted on a house. Moving in on or around the 20th April. More importantly I will be able to store my blade at my home instead of 6 miles away in a secure car park.

Looking for a bit of advice on a little shed project I plan to build in the summer. I am not a builder by any means so hoping you guys can answer some questions that I may have. Approximate size of the shed will be 3200L x 2400W. I think the height has to be less than 8ft otherwise i'll need planning permission to build it.

The construction will be generally timber stud work 38 x 63 for the walls and rafters. The floor joists will be 45 x 120 with 18mm OSB for the floor.

Can anyone with some building knowledge share their wisdom and confirm if those sizes seem ok and will be strong enough to build.

Cheers

Hi Mate,

Congrats on the New pad. I wouldn't use OSB for the floor its like cardboard when it gets wet, I would get a decent 3/4 ply. I would get some damp proof membrane to cover the footings with, this will help protect it a bit from the weather.

Make sure you start out with level ground as it will be a nightmare if not.

you can build to 4M according to this

Not too sure of how up to date that is.

how about a prefab concrete one instead? they cost about the same as wooden ones.

[Talking Heads]

Much easier to insulate and double skin a wooden one though.

Total height 2.5m if you're within 2 metres of the property boundary. The limits are more permissive if you're more than 2m away from the edge of your land.

Most sheds are designed not to exceed these wherever you put them.

Thanks.

The shed will be located less than a metre from the boundary wall so the maximium height is 2.5m according to the guidelines.

Do I use a DPM between the ground and the floor joists?

[Bibio]

from boundary its 3ft in and 6ft up in old money. height to be no more that 8ft no matter where situated. if it dont comply to any of these then planning permission is needed.

I notice my information comes from https://www.planningportal.co.uk where you can select "England" or "Wales" so god only knows what goes on up there past the wall :p

[TheRamJam]

Cool so less then 8ft is fine by the whistle blowers.

Any ideas as too cladding the outside with. Had a look at traditional shiplap but this is coming in at stupid money for the size of shed am building. One idea was 18mm ply, a suitable DPM layer, then shingles that look like tiles then wooden fascia to edges etc.

[Bibio]

BTW the side of the shed/garage can be right up to the boundary as long as the height is not more that 6ft from 3ft at the boundary. if your over 3ft from the boundary then it can be 8ft.

lets say you put a 'apex' roof shed with the slope going towards the boundary directly up against the boundary then as long as the height of the 'slope' at 3ft in from boundary is 6ft in height or less your fine to erect without planning permission. if you do the same as above but put the 'front/back' of the shed at the boundary and the height of the apex is over 6ft then it fails the regulations and planning permission is needed.

i have looked at building a big shed in the back garden but looking at the costs with tongue and groove timber was silly money compared to a prefab concrete one which i was surprised how little it was for a 'secure' shed/garage.

build it cheap.. build it again in a few years.

Good info in here, my wife and I are at the house hunting stage but nothing has popped up yet and if we can't get one with a garage then it will be a decent shed.

Good point Lance, if I orientate it correctly and have the slope going towards the boundary then I should be ok.

I have created a plan for the roof joists and placed the 18mm ply floor on top of 45 x 95 joists at 400 centres.

dont go too mad with the timber your not putting a car in there. 600 spacing is fine with dwangs. using 400 without dwangs can result in things moving, better with dwangs.

use treated rough sawn.

use dpm on bottom of walls where it connects to the floor.

Floor redrawn with 600 CL timbers and dwangs.

Got the studwork up too. Just need to work out door and window size and locations.

Gable wall with structural opening for the door. I will add some dwangs in to support the worktop etc. Roof rafters will have gussets and strengthening diagonals.

if you lay the flooring along the 2.4 you can use 2 dwangs. the dwangs need to be staggered or you wont be able to nail the ends or use lap joints and nail from above.

which ever way you lay the flooring you need to make sure that all ends sit on a joist.

if your going to line the inside with PB or chip then you need to remember to have stud to fix to in the corners so go one size up for that purpose. lets say you use 50x75 for the main frame, you would either need to nail 2 bits together in the corners along the side frames or use 100x75 in the corners (ends of frame). or put the '75' face on, on all stud work. again use dwangs if you can.

building a shed is the exact same as building internal stud walls in a house.

[Teejayexc]

Wtf is a dwang? Do you mean noggings?

Talk English man. :smt021

[Bibio]

north of the border here... lol

If you are thinking of storing your motorbike in the shed be careful, as already discussed on this forum your insurance will insist on a brick or concrete structure.

I have decided to opt for a lean to shed build. Construction costs will be roughly 12% cheaper and probably easier for my basic DIY skill level. This is what I have drawn, it's 1800 wide instead of 2500 wide and 3600 long.

The plan shows a L shape worktop for the moment but this could change as this effectively limits the space to single sided working on the bike at any one time. However the outline shape of the bike is exaggerated because its calculated at its widest part being the tips of the wing mirrors.

I wish to put a few sockets into the shed and a light switch. Any ideas as how i could connect this up to run off power from the house?
