More WIP buildings

Hello,

last two days I've been working on the exterior of my buildings, to get things moving somewhat.

Here are the pictures:

The picture below shows you all the buildings I currently have. There is 1 bigger, 1 story house with a garrage, two little twin houses, an apartment block and a box store I showed few days back.

All I was doing these two days was actually building roofs and sticking matches around the buildings.
Here you can see close up on front and behind of the little buildings. They're supposed to be identical. Right doorway, however, has a bit dented step, i cut a bit too short again, and figured some variety could be nice. 

 A close up on zombeighors, having a little mornin' chat.

The mighty apartment building from front. There is an apartment down bottom, on first floor and on top floor. Top one is a bit smaller but has a terrace that offers a nice view of the town. Needs fencing, we don't want anyone to fall off, do we?

 The side of the building:

 ...and all the components:
You can see top floor, with little "box" for staircase, ground and first floor are basically identical, except for the fron doors, of course. The thinner section is for staircase, which I might or might not build once. It would be "snail" type, a little 5x5 cm "cube" that starts low and grows , you get it :P

 I will do some "garage" doors for delivery section of my box store: That is the "top" section, with two openings. In the "store" part, there will be glass doors. Or none, but you know, a man can plan. Naturally, floor plan is smaller than expected, so once I get to building shelves, I have to rethink my strategy.

 And for the end, the building that still looks quite small, but way too big compared to others, the "suburbian queen". building from front. Blue zed is in a garrage.

 The little variety:

 Here is the 3x3 board, using paper "testers". It looks funilly largely-small. Mostly small. I've only used cars from poundland, didn't bother finding the others, hehe.

 Most of the cars are too big. Especially the police and bus. Here, each lane is 5cm wide, plus 5 cm for sidewalks + 5 cm spare (each side). If you add a sidewalk, two police cars can't meet, and don't get me started about the bus.
I was thinking I would add another centimeter to each lane, and another half centimeter for each of the sidewalks. That half would be on half of the sidewalk and I would "plant" hedgerows, dividing sidewalk on two sides - for bikes and for pedestrians - as its done here, in a town close to me. Still don't have the picture, but I guess you could imagine.

The problem is, I lose 5 extra centimeters on each side. It leaves me with 3.5, which is still something...but i lose the simetry of 5. Its not something really disturbing, to be honest. And on the plus side, I would really like to see my bus drive around normaly.  The thing is, 5 is enough for other vehicles. How wide are the roads you guys are using?  And I would love to hear your opinions on that, don't want to start building a board and end up with something that I don't like.

Oh, and I've ordered some hasslefree minies, but more on that when they arrive! :P

Cheers,
Matevž
