Hidden away in a shed

Hidden away in a shed

Finding storage space for all those things that don't quite fit in the garage is easy when you have a garden shed.

Enjoying and beautifying your backyard can be relaxing, but it can also get crowded and messy. There's lawn furniture, gardening tools and perhaps even pool equipment. And don't forget the bicycles, tools and other odds and ends that just can't find a parking place in the garage. An outdoor storage facility is the answer to your bulky storage problems.

When you build one with durable pressure treated SA Pine you can count on some long-lasting protection for all those items you need to stash away and secure. This plan is adaptable to meet your storage needs. Three flooring options are specified and an optional ramp can be built to help get a wheelbarrow or mower in or out more easily. Inside, the 76 x 38mm stud wall will simplify the installation of shelves or hardware from which to hang tools.

The pressure treated exterior siding can be painted, stained or left to weather naturally to a silver-grey colour. When you complete this project, get back to relaxing in your outdoor living environment, knowing that everything is in its place.

MATERIAL LIST

Very few timbers are naturally durable. Hardwoods that are durable can be very expensive. These timbers that are more durable can split and will require some form of protection. The cheaper locally grown timbers that can be used are pine and salinga. Fortunately, with proper impregnation with a suitable wood preservative, these timbers can offer long term durability.

There are various timber preservatives available. Some are not suitable for timber in ground contact, whilst other protect timber in all possible applications. Creosote and CCA preservatives are equally suitable. CCA timber has a greenish colour, while creosote colours timber dark brown and black. Timber treated with Boron or light organic solvent preservatives (LOSP) does not change its natural appearance. The latter two preservatives, are however, leachable and should therefore be maintained with a suitable water repellant wood sealer or finish.

This water repellency property has to be maintained to prevent leaching of the preservative. A water repellent wood sealer also protects the timber from degradation resulting from weathering. In order to also inhibit the effects of ultra violet rays an inhibitor may be added in the form of a red or brown colourant.

Remember, the use of treated timber ensures that a shed is protected against attack by termites, borers and fungal decay. Should it be necessary to paint the timber to match existing structures Boron, light organic solvent preservatives (LOSP) and CCA treated timber can be painted directly. Creosote timber can also be painted, provided it is first coated with a bitumous based aluminium coating.

OTHER MATERIAL NEEDED

  • 63mm, 10mm and 125mm hot dipped galvanised wire nails
  • 3 pairs, 100mm galvanised butt hinges
  • Water repellent sealer
  • Construction adhesive for treated timber
  • Door handles and lock sets (lock and hasps) to your choice
  • Four 0,9 x 3,3 m fibre cement building boards as roofing sheets
  • 63mm chipboard screws, for fastening roof sheets and boards
  • Two 1,2 x 2,440m tempered pressed boards for door cladding
  • Two 600mm standard weather bards for doors (optional)

CONSTRUCTION STEPS

  1. Determine the exact location of your storage shed. Position 76 x 50 main bearers at ground level, parallel to the front and rear of the shed. Use stakes, line and level to aid placement of main bearers.
  2. Cut the two 288 x 38 header beams to 3m. Make them stand on main bearers. Cut the eight 228 x 38 floor joists to 2,924m. Place them between header beams of bearers at 428mm c/c, maximum 450 c/c. Secure joists to header beams with adhesive and three 100mm nails per head joint. Make sure that joists to header beams are square and level, refer to isometric and sections. Use double joists under gable walls, nail fix together.
  3. Toe nail the joists at header beam framework to main bearers with 125mm nails. Check level and square.
  4. Make sure that floor structure is square and level. Use forty 22 x 63 x 3,3m tongue and groove floor planks. Place the first plank on the corner and edge of the floor structure and check for squareness. Apply adhesive to the top of the joists. Nail fix floor plank to joists using two 63mm nails per joist. Refer to isometric.
  5. Fabricate the rear 3 x 2,4m stud wall using 76 x 38mm studs at maximum 600mm c/c. Size eight 76 x 38mm to 2,1m. Lay them down on a flat clear surface. Size 76 x 38mm top and bottom rails to 3m. Mark out centre positions of studs on top and bottom rails. Nail fix studs with two 100mm nails per joint. Check for squareness. Refer to isometric and sections. Use double studs at corners.
  6. Make the front 3 x 2,4m stud wall following the same procedure as in step five. Size ten 76 x 38 studs to 2,1m. Measure 1,2m, 600mm off centre line for door opening, placing double 76 x 38mm wall studs as marked. Size two 152 x 38mm lintels through studs using three 100mm nails per joint. Directly under the top rail apply adhesive to all jointing surfaces. Refer to section and isometric.
  7. Manufacture the two symmetric side walls. Follow the procedure as in step five. Size ten
    76 x 38mm studs to 1,2m and two top and two bottom rails to 2,248m. Assemble the frames as with the other. Note, no double 76 x 38 stud to the corners. Check for square.
  8. Erect back and one side wall frame on the floor and foundation system. Make sure that the frame is flush to keep it upright. Erect the other side wall frame and the front frame and brace temporarily. Loosen one frame at a time and get it plumb and square and fasten the bracing again. Repeat with the two other frames.
  9. Secure all the frame to the floor joists with 125mm nails at 600mm c/c. Size two 76 x 38mm wall plates to 2,4m and two 76 x 38mm to 2,848m. Check frames from plumb. Back wall and one side wall frame should be diagonally braced with a 63 x 22mm floor plank, checked into stud to form a flush surface. Adhesive and nail fix with 63mm nails to all joints. Nail fix frames through studs to each other. Check for plumb. Brace wall frames on top of top plates with 76 x 38mm wall plates, securing with 100mm nails.
  10. Size two 76 x 38mm gable studs to 1m. Size one 228 x 38mm ridge beam to 3m. Secure gable studs at 1m on top of centre lines of 2,4m wall frames by toe nailing it to wall plates. Check for plumb. Secure ridge beam on top of gable studs with 100mm nails and adhesive. Refer to isometric. Standard nail plates are recommended for securing ridge beam to gable studs.
  11. Size twelve 1,8m x 152 x 38mm rafters to 1,7m by referring to detail section A - A. Install roof rafters directly over studs on wall plate and notching wall plate position into rafters, 38mm to form heel joint. Nail fix rafters to the ridge beam with 125mm nails and adhesive. Secure 76 x 38mm roof braces as shown in isometric.
  12. Attach two 33 x 152 x 25 fascias to the end of the rafters with 100mm nails and adhesive.
  13. Cover roof with four 0,9 x 3,3m fibre cement building boards with 63mm chipboard screws to rafters. Place boards overlapping each other, to form weather tight joints.
  14. Install weather board siding to frames with two 50mm nails per stud. Make sure the overlapping fits tightly. Trim corners and mitre boards to fit in at the gable under roof. Refer to isometric.
  15. Fit corner beads with 63mm nails to corners of weather board. Refer to isometric. Complete trimwork on rafters and install 114 x 25mm scotia on external cladding (optional). Refer to section B - B.
  16. BUILDING THE TWO DOORS: Size four 2.1m x 76 x 38mm door jamb studs to 1980mm and four 600 x 76 x 38mm door top and bottom rails as shown in isometric using 100mm nails. Fit one 2,1m x 76 x 38mm bracing strip from the corner. Refer to isometric. Cut 19mm tempered chipboard to fit exact parameters of doorframe. Screw fix board to 76 x 38mm frame using 63mm chipboard screws. Construct two doors and fit 100mm butt hinges. Add your choice of door handles and lockset as desired. It is advisable to fit weather bars at the bottom of the doors.

  17. Construction is complete. Take care of fine finishing. Apply one or two coats of water repellent sealer to the external cladding and floor boards. Paint the roof with your choice of colour.

BUILDING TIPS

  • Hot dipped galvanised or stainless steel nails and fasteners should be used.
  • Fasten horizontal members (deck boards, stair treads) ‘bark side up' noting the direction of annual rings.
  • When nailing toward the end of boards, pre-drilled holes or blunting nail points are recommended.
  • Sawing should be done outdoors while wearing a dust mask.
  • Eye goggles should be worn when power sawing or machining.
  • When construction is completed, the application of a water repellant sealer is recommended.
  • Treated wood scraps should be disposed of by ordinary refuse collection and should not be burned.
