Thread: About to build a shed !!!!HELP

Get the first one right and the rest should be fine.

You are going to do frame on ground and stand them up?

It looks like these are pre-fab sheds. First set one corner and add braces to the ground to hold it in place. Stand the next wall against the first and square it. Now secure both walls together and continue building the other two walls. Everything should end up square enough once you get the first corner aligned.

cheers for that mate i will put some pics up when i finally get it stood

Measure across the diagonals and if square they will be the same.

I assume it's a portal frame shed ? Getting those square isn't that hard. The devil in those things is the details. If in doubt call the vendor.

6X9 is a good size. Mine's 7.5X9. I got a higher pitch roof but should have also gone 3m walls. They aren't much dearer but help keep the radiant heat off in summer and allow much higer shelves and you can swing big long things around without hitting the roof quite so often

Before you fill it up you might consider putting some bats in the walls/roof and lining it with something cheap. Insulation will make it a much nicer workshop in extreme weather.

Good luck

Foil backed insulwool blanket is relatively cheap and simple to put on at the time of building.

Use mesh to support it and lay your roof on top.

I have found my shed to be only a bit warm when it has been 47 degrees outside. The insulation on the roof also reduces condensation in the cooler months.

Good luck with the building and enjoy it when it's built.

i'm with Damian about the hight of your shed,the walls go higher if you can afford the xtra and havn't purchased yet ,your shed size is ok

As Wongdai said: measure the diagonals. And use reference lines! A spray can of line marking paint will do.

If you want a "step by step":

Mark the slab where a corner of the "first" wall will sit. I like to use conc. nails driven flush into the slab, but a simple mark will do if you're accurate in marking and careful not to scuff it later. If using line marking paint, use the inside edge of the paint line as your reference, 'cos the lines are too thick to just "guesstimate" the middle with any accuracy.

Measure the length and mark the next corner, taking care to keep it square to the slab. Using a long tape from the first mark, measure the length to the end of the 2nd wall and put a temporary mark. Using the tape from the second mark, measure the diagonal - with walls of 6 & 9m long, it should be around 10.82m long. (a²+b²=c²) Where that intersects with the temp mark, make a permanent mark for the third corner.

Repeat to get the last corner.

Re-measure everything to double-check: both diagonals should be exactly the same length. Take your time, get it right... much easier to move a marker than to try manhandling walls around later. If you like, you can run string lines between each mark and use the line marker to clearly establish a base line for each wall. (Personally, I just use the corner marks.)

Finally, it's simply a case of positioning each wall so the bottom corners sit on the appropriate marks and LIFT.

put in the isulation foil in the roof before you put the outside iron on will save a lot of work in the future if you are lining it

G'day Cecil.Here's my advice:

Read the instructions.

There are some interesting people here. Some even read the instructions.

Instructions? Bah! A real man doesn't need instructions!

At least... not until they're the last resort.

teh instructions are good for makign a fire to boil the billy at smoko time.

measuring diagonals and marking out the slab is the best way to get it square.

I would like to thank everyone who has replied to help me out it is much appreciated.I am still laughing out loud about the instructions comment, Sarcasm is not my strong suit,but obviously some people think they are funnier than they really are. To those who replied to help thanks very much some of those ideas are really great and i appreciate your help.I will keep this updated when i start building her. Unfortunately i have pre purchased the shed or i would have got the higher one. What sort of mesh is best to use to go under the insulation?. if anyone could help that would be great.
