  3. Compact bases for all holes.


  1. Put Column A in first hole, in centre, secure plumb and put soil back, and compact in layers of 150mm. Make sure that the column is plumb at all times.
  2. Repeat step 1 for column B making sure that the centre lines are 1,5m apart.
  3. Repeat steps 1 and 2 for columns C and D.
  4. Trim ends to secure same level height.


  1. Secure rail in position as shown on plan to columns A and D. Drill holes and fasten with 300mm threaded rod and nuts. Fasten tight.
  2. Repeat step 1 for rail F against columns B and C.
  3. Secure rail E in position against columns A and D and under rails H and F. Secure with bolts and nuts.
  4. Repeat step 3 for rail G against column D and C.


  1. Secure the ring beams L and N to columns A and D, and B and C respectively to height 950mm from the top of the columns, with 2 x 75mm nails per column. Make sure beams are level.
  2. Repeat step 1 for beams M and O to columns A and B, and D and C. Trim end.
  3. Secure joist beam I in the centre between ring beams M and O as shown, and headnail fix it with 2 x 75mm nails through beam M and O.


  1. Nail decking strips with 75mm nails to ring beams and joists as shown, using one nail per joint.
  2. Trim ends of decking strips to fit where necessary.


  1. Secure stair strings I and J to columns D and C respectively directly under ring beam O, using one bolt and nut per joint.


  1. Nail fix droppers, as shown on plan, on stringers I and J with 1 x 75mm nail per joint.
  2. Allow for +70mm openings between droppers.


  1. The structure should be protected with any good quality wood penetrating sealer containing a water repellent, recommended for external use. Sealers must be maintained as per the instructions on the product label to ensure maximum protection against weathering agents i.e. UV, temperature and moisture.
