As a fan of extreme biomes (beach, desert, etc.), I would very much like to see some pictures of your desert Fortress.
It's not much to look at right now, we've just survived our second year, and after two failed attempts (One dehydrated melancholic and a berserk who went down to a 5 dwarf dogpile) we've just produced our first artifact! It's a glumprong ring. I wish I had enough wood to get any use at all out of a legendary woodcrafter but my own moral code won't allow him to conscripted as cannon fodder. Dude arrived as a papermaker so maybe I'll give him a job as a scholar.
Pictures at varying levels of zoom!
Surface level. I forget what we originally built the depot out of its been covered in goop so long. Probably glumprong. Lovely red cinnabar for the outer doors of the main fort and glumprong from the inner. Planning on turning the narrow entry halls into trapped chokepoints.
One level up the Matched Tummy sits above the trade depot, this way all traders and other guests don't have to enter the main fort to enjoy our hospitality. In the event of nastiness arriving they can lock the doors and hatches and hope that works. Will probably remodel this later. I'd like an ultra grand residents tavern above it.
Above this sits the guest rooms with railed balconies. Over in the main fort you can see the beginnings of the battlements. I'd like to also place noble's quarters up top.
Underground we have the original shelter dug when we first arrived, now a farm. Not sure what I'll do with the old dry moat, plans have changed since I dug it.
Next level down is livestock, with a servant's passage leading directly to the kitchens.
The main fort as it stands is in the first two stone layers. North of the main stairs are workshops with stockpiles next to and below them.
The dining hall is somewhat neglected at present, also housing a temporary barracks. Several hatches open into the food/drink stockpiles beneath, across the servants passage is the kitchens. Also in these narrow passages is our placeholder mausoleum. Eventually we will have a grand surface monument, but for now this keeps our dead out of sight.
Back up on the main level our hospital and adjoining waiting room in the south has just finished being dug out and smoothed. North of those are the future mayor's quarters and the broker, sheriff, cmd, militia commander's offices, and off to the east are bedrooms. A lot of this will eventually move aboveground probably.
