Hello again folks. My old profile of Kalebdaark got messed up on a technical level so I had to restart my account. I don't mind starting over though, because content is what matters, not title. You can find my old content anyway under:
https://leadadventureforum.com/index.php?action=profile;area=showposts;u=4831But let's get started with the real write-up here, shall we?
This one took a while. I've been working on it on-and-off for a few months now. I've always wanted a quonset hut dive bar, similar to the original Fallout's SKUM PITT. So here it is:

Because I needed a larger than normal diameter, and a good deal of durability, I used a cut off short section of sewer pipe, which I cut with a circular saw. Messy. If you want to try some other material such as cardboard tube or the like, then your initial shaping process will be easier. I then dug out a few sheets of corrugated styrene, cut out several pieces of plating, and glued 'em onto the half-pipe with super glue. If I had to do it again, I'd use larger sections instead of a bunch of smaller plates. But what's done is done, and it came out pretty well. The windows were of clear styrene, and were painted prior to assembly.
The base is a piece of 1/8 styrene, but more on that later. The brick base is made out of legos, with the topmost nubs ground off and plated over with smaller sheets of styrene. They have a great cinderblock look. Give 'em a quick spritz of textured spray paint and then prime in gray. I primed the main plates with a combination of gray and tan just to give it some color variation. An interesting feature of old concrete or cinderblocks is that they are mostly gray, but for darker edges as water, grime, and weather do their work. Dry brushing the corners with a dark brown or blackish gray works best, with black pastel chalks lightly applied to the recessed corners.
Then comes the rust. This will take you a bit of practice to master. If you pull up pictures of old quonsets, you'll typically find an overall gray or tan color and then some dark rust on the highlights (dry-brushing), some rust along the edges (washing and dry brushing combo) and some larger patches of both old (darker) and fresh (lighter orange) rust. These were achieved with pastel chalks close to the end of the process. Use chalks as the last step before sealing it with flat.
The roof hardware is composed of model railroad details. I use O scale as that's the closest to 28mm. The chimney is a caboose smoke stack. The ventilation spinners and AC units are all available online. Try eBay.
Here are pictures of the front and back. I used tiny printouts of old poster and signs for detail.


Speakin' of which, if you want those signs for your own dive, here they are:

The first speaks for itself, the second outlines the rules: "MEN: No Shirt, No Shoes, No Service. WOMEN: No Shirt, No Shoes, Free Drinks". Apparently a real sign somewhere out there in nowheresville.
The main sign was cobbled together from parts, with the girlie outline and "bar" being part of a pack I bought through the shapeways 3d printing service. Heavily washed and rusted. This hooks onto the front of the building so the building can be used as some other non-gin-mill location.

The base itself is a 1/8" piece of scrap plastic. I used a dremel and ice pick to carve the recesses. Then I primed in a light gray and used several washes and inks to bring out the cracks. You can get even more messy and stained if you wish. Go to old auto garages, hangars, abandoned retail buildings and the like to check out the massively stained concrete floors. That should give you some inspiration. Be careful of rats, bums, and other nuisances though. Use some of your figure base "flocking" material and grass tufts to give your sidewalk those extra bits of detail. Plants usually bust their way through the cracks on neglected building grounds.

The stage is a simple plate of stained coffee stirrers and the woodpile is a simple stick snipped into several "logs" and glued together:

The Bar itself is a laser cut interior item, and the stove is a model railroad item. For the stovepipe, I used thick solder. It bends well so it works great for these kinds of applications. The "soiled dove" bar paintings were printed off the internet. I'm sure you can find something suitable to add to your locale's atmosphere.

I hope you've enjoyed this happy little interlude at this peaceful little....... Oh well... you already know I'm not Bob Ross so there's no use pretending!
Enjoy!
