Ur was an important Sumerian city-state in ancient Mesopotamia - the word has been used to mean the first or the best.
I tried to make an effective outpost to keep the northwest safe.

I have tried and tried to make an electrical grid that will function.  After many hours and different efforts (Including just carpeting it in generators) the only solution that just works is to got o the Workbench and select Power tool and Faux Power.  This will sing a sweet lullaby to anything that uses power convincing it it always had so much it can never run you.  Each level adds a few new plots so you will need to select it again to get them on board. 

Level 0  Pop 12 -
Starts building up the place, adds in a shrubbery wall so the only way an NPC can get in is the bridge. 
I put a bed the player can use in the house by the workbench - its on top is a medical bed.
Comes with a fantastic guardhouse [EH] Gatehouse by Eldarth*
comes with a school - check out the cat house by it.  Dog too :) **
The building in the river is basicly fluff.  But nice fluff.
You still need to kill the roaches if you haent already.  If you use Workshop Plus use insert to activate additional item selection and you can 'recycle' the insect bodies to get rid of them.

If your so inclined check out the different buildings as it builds.  I tried to not pick the same plot twice.  With the exception of a few 1x1 I think I succeeded.
The power room, water pump and later plant will help keep your settlement in power and water regardless of the local supplies you have. 

I heavily suggest using the Workbench power tools to set it to faux power.  You'll need to come back each level and do it again to catch the new plots.  This settlement is simply to buggy for power to work otherwise.  Ive tried covering every inch in lights and generators and I couldnt stop them from cutting out and not wanting to come on.  It has wiring for the looks mostly but trust me Faux is the never worry solution.

Depending on how you play the Clean My Settlement Redux might be a good way to get rid of the thick brambles in Sanctuary.

Level 0 I left as much of the junk as I could (esp containers) so you can still loot them.  But they will be mostly wiped out in level 1.  The materials in the container should go to the workbench.

Level 0 I tried to include a lot of vanilla beds so if you quickly get settlers they arent complaining as much.  I phase out most by level 3.  The bed in the medical center (in the house by the workbench) wont move.  Its meant for survival saves and turning it t day.

* I adore the gate but it doesnt have a level 3 in it.  So if you use commands to advance the plots in the settlement to level 3 it will be empty but somehow still functioning (?) if you use the customize option on the ASAM you can swap it to another lot type then back to Martial and restore the gate though it will lose any progress to level 1 and 2.
** Its in the barn on your right heading into the settlement - go in and use the computer to have it expand to 3, 6, or 9 seats.
