In order to Keep It Simple Sailor (KISS) there are only two types of basic building blocks for a PBS-style town: full and half-blocks.

	baseplate	"street"	example
Full	32 x 32 studs	Minimum of 4-wide on all four sides.
Half	16 x 32 studs	Minimum of 4-wide at front and back of block.

Streets

The narrow streets are built using two layers of plates. The bottom layer can be pretty much anything (unless you are making something to be seen like mud, hole in the street, etc). The top layer should be a random mix of round plates either 1x1 or 2x2 studs in a mix of colours (usually greys, browns and black). This is to give a cobblestone effect and can be modified if needed. Just remember that the street will usually butt-up against another street made by someone else.

It is possible to build wider streets or even to create a public square that is virtually all filled with cobblestone. The four-wide is a minimum to make sure there is some sort of street network through the whole town and to make some space between buildings.

Build Space

Within the build space (green in the picture at right) you can build whatever you like. Houses, taverns, stables, blacksmiths, taverns, brothels, taverns, warehouses, taverns. The list is limited only by your imagination and don't forget the taverns.
