A DIY Guide To Build A Cheapest Shed

Remember when you bought your first house and built the shed to store all your junk in? It was a laborious process, wasn’t it? Well, it doesn’t have to be if you follow the step-by-step guide below. By using some basic tools that are available at any hardware or home improvement store you will be able to build an 8x4ft garden shed for just under $300-$400.

This cost does not include timber because this is best purchased from a local supplier who has a woodcut to size for cheaper than buying off the shelf at a hardwood/timber merchant. If your drive isn’t big enough for this then make sure you buy 4ft boards because one 2×4 board will yield four 4ft boards.

The whole process is very simple and will require less than 3 hours of labor to complete if you follow the guide below.

Tools Needed:

– Circular Saw (to cut 4×4 lumber)

– Tape Measure & Pencil


Materials Required: –

2 x 8ft 4×4 posts for corners – 1 x 6ft 4×4 post for center beam between corner posts – 2 x 24ft 2×4 planks for wall studs – 50mm TimberNailer (optional, but makes construction easier by hammering nails in) or 16/16d nails  – 100 galvanized roofing nails (approx 22p per box) or 1 box of 100 100 if not planning to use roof roofing nails. Paintsaints recommended for building a shed – 4 x 4ft sheets of exterior grade plywood – 10x 26g roofing nails or 1 box of 50 if nails not planning to use

– 1 x tube construction adhesive from local builder merchants.

Options:  – If using an extractor fan then purchase an extractor fan/light unit from a hardware store instead of a plywood sheet.

Total Price Of Materials To Build Shed: Approximately $300-$400 (cost taken from closest home improvement center)

Steps To Be Taken:  

1.    Mark out the posts on the ground with a tape measure and pencil. Draw a line where you want your doors to be and another line in the center of these for your base plate

2.    Drill a 50mm hole in all 4 corners using a post hole auger or regular drill bit to make room for the corner posts.

3.    Using a long piece of 2×4, mark out positions where you will place all 4 corner posts to ensure they are level/straight

4.    Dig holes deep enough so that when post is set at the right height (approx 1ft) there will be 1-2in above ground level for anchoring purposes

5.    Set up two of the side walls by hammering in 16d galvanized nails through the 2×4 wall studs to secure them together. Make sure that the windows are on the side you want to be facing outwards because once placed against each other they are hard to move without dismantling them again

6.    Place roof over the top of walls and nail it down with 100 nails or if using TimberNailer, leave off until Step 7

7.    Hammer 50 nails/use TimberNailer to secure base plate onto corner posts

8.    Hammer 100 nails/use TimberNailer to secure your wall frame securely onto the base plate (if necessary)

9.    Set up opposite two side walls but DO NOT hammer in any screws or nails

10.    Place back wall onto the side walls so that it is secured between them at regular intervals

11.    Hammer in 50 nails/use TimberNailer to secure your roof onto the back wall so the four studs are joined together with 100 nails/TimberNailer. This will prevent any sagging of the roof until you have finished all walls

12.    Attach your front and final sidewall to give a closed shed

13.    Cut out a section of plywood sheet for the door and two smaller pieces to go on either side of the door as support panels

14.    Drill holes into each corner post where they connect with your planks on your walls (do NOT drill through planks) this will be used to secure the two “support” pieces of plywood

15.    Place your planks onto your walls so that they overlap each other by at least 1in or 2in if possible. Screw or nail them down securely using 50 screws/nails

16.    Check again to make sure all screws are in tight. Any holes can be filled with extra slats that you have cut off but any wood filler will dry out over time and need sanding before painting

17.    Nail or screw hinges into wall studs, you have four options here for this step depending on how many doors you want, if 1 then use 6ft 6in hinges, if two then use 13-inch hinges (total of one per door)

18.    Attach plywood sheet to back wall for the door with 50 screws/nails on hinges  (1 per hinge if 1 door, 2 per hinge if 2 doors are being used)

19.    Make sure that this last piece of plywood has an extra 2 pieces nailed onto the side as support panels so it remains sturdy when open

20.   Secure the door with proper hinges by screwing them in place so they don’t fall off easily, but do not overtighten or you will split the wood

21.   Nail or screw handle onto the door so it is easy to grip and open up at all times along with any other fixtures that may be required

22.   Paint the entire shed in the color of your choice and let dry

23.   Install shelving or anything else that you may like to add to your shed

24.   Hang lights from the ceiling if preferred (you may need electricity installed for this feature)

The doors can be hung by either hinge on either side, but when closing it must close inwards otherwise the hinges will become damaged over time.
