===Making the New Hub room===
Add the frame of the Zero Zero nether portal using 12 obsidian blocks, against the zero zero point, on the south side . * This is hard to describe but Zero Zero is a point between four blocks rather than a block on its own. So the portal can't be dead centre. The mock-up puts the portal facing north/south, and I think it's built on the south side of the zero zero point - putting 19 blocks between the portal and the south wall, and 20 between the portal and the north wall. Get some crafting tables and ovens up in here for convenience somehow.
===Cosmetic stuff in the new nether hub room===
After all eight tunnels have been marked out, use wool to mark each archway as in the mock-up. The top two corners of each archway are sea lanterns. There's some wool in the box in the middle of the old hub. * North: red * North-east: orange * East: yellow * South-east: green * South: blue * South-west: dark blue * West: purple * North-west: grey These colours are not final and may be subject to change. We were undecided in the group about which colours we should use, and so here I am using the colours that are in the mock-up . Once the archways are in place, replace as much of the walls as possible with quartz blocks, floor to ceiling. Take quartz from the old nether hub walls, and when you run out, start using snow and/or white wool blocks.
===Getting the tunnels started===

Dig out 10 blocks or so of each of the 8 paths and label them with direction signs. * North, South, East and West are centred on the relevant 0 co-ordinate, and each are 4 blocks wide. * For the diagonal roads, copy the mock-up design (picture to the right).
Anyone who likes a lot of digging can
extend and/or pave these tunnels.
* Paving is builders' and residents' choice.
* Lengths of road we need are:
** North: 200 blocks, ie: to x=0, z=-200.
** South: 900 blocks, ie: to x=0, z=900.
** East: 200 blocks, ie: to x=200, z=0.
Pave the entire 40 x 40 room with smooth stone slabs.
