http://en.wikipedia.org/wiki/Khrushchyovka
The most prominent feature of Soviet landscape, notorious for its paper-thick walls, stinky staircases and sewerage with sadistic disposition. They are everywhere, thousands of them, forming dusty concrete labyrinths for homo sovieticus to live in. Off the top of my head I can think of at least three reasons to have them in Il-2:
1. With just few different models of Khrushchyovka you can create entire modern cities and therefore simulate every possible combat scenario in Warsaw pact countries from the 60's to the present day.
2. This model is very easy to create. All you need is a box of appropriate proportions and a skin. I volunteer to draw one, unfortunately I know nothing about 3d modelling and class files.
3. Popularity of Il-2 and SAS may rise tremendously, as everyone who have ever experienced horrible life conditions in these houses is eager bomb the crap out of them.
Also there are some variations, such as Brezhnevka: Khrushchyovka on steroids, featuring several (usually 4) additional floors and waste disposal system that itself could be classified as a medium-sized humanitarian disaster.
A multitude of variants can be made (with different heights and color schemes) hence the simplicity of this model. My recommendations:
Model 1-335. The most numerous of them all, built from 1958 to 1966. Dimensions (approximate): length 35 m., height 15 m., depth 12 m. Sometimes has small pitched roof (can be ignored).
Model 11-49. One of the most common Brezhnevkas. Built from 1965 to 1984. 52x25x13 m. Usually has small elevator shaft extention at the top.
Model 111-121-8. You can find lots of them in rural areas and military bases. Built from 1970. 21x9x12 m.
It would be awesome to have all these models (I can paint several skins for each, therefore at least 6-7 different objects could be made). In the worst case only 1-335 will be enough.
These buildings you are asking for are not needed to be built as new 3d-models. There are already in the
game many building models that can be painted to look like these housing complexes from the late 1940s-50s-60s.
These are not new ideas constructed after the WW2.
Many years before WW2, in the late 1920s and 1930s, there was new group of artists and architects which
worked together on new and revolutionary housing projects. It was called the "Bau-Haus" group.
After WW1 new ideas had to be elaborated to create housing complexes for the new generation and to re-constructed
a devastated Europe and its cities.
So the Bau-Haus group were designing these cheap to build buildings and
cheap housing for poor people. Many of them had this "cold look" to them, because many of them did not use paint or
fancy things on them. It was just cement and straight forward line-art to the designs.
It was the age of modern construction and the age where many buildings were built around
a design to please the new "revolution" of the country politics and its leaders (dictators).
In this case, The German Third Reich, and the Stalin-era politics.
It is possible to paint and create new buildings for the IL2+mods using the already available
3d-models we already have.
I do have in mind to paint a few of these Bau-Haus building designs for my personal game
but I can share them with you, if you wish to use them in your WW2 or jet-era maps of your game.
Such big housing complexes can be used for many diferent countries and on many maps.
The "Lada" car I do not have in my game. That is a model which is not available.
But perhaps one day some 3d-model-artist could create for us some 1950s style car design for the IL2 game.
There are many free low-poly models available on the internet.
Some static-model cars are always good to place in the cities to make them look alive as if humans live in it.
