picket fence and gate (Abingdon OX14)

I replaced this fence even though it was in great shape, just to change to a different style, and then left it in the garden for a few years... It definitely needs sanding and probably painting, but the timber itself is pressure treated and hence still in pretty good shape. Some of the slats have fallen off and need to be nailed or screwed back in. That's why things look a bit crooked in the photos - I just leaned the loose slats against the panels to make sure they are all there. I have:
- two fence sections 2.0m wide, 0.8m high
- one fence section 1.4m wide, 0.8m high
- one gate, 1.0m wide, 0.8m high
- four fence posts, 85mm x 85mm, 0.9-0.95m high, with ground spikes 0.6m long
- one extra ground spike
