Inspired by the famous farmhouse in the Battle of Waterloo, and with a brick imprinting roller purchased by happenstance from the local hobby store, I set about to create my version of a Belgian farmhouse from pieces of foamcore, card, and sheets cut from those styrofoam meat trays from the supermarket - served both in black and white. These give you a cheap means of thin walls of brick to work with although the 'gate tower' used a one thick piece insolation pink foam which makes a better/deeper impressed pattern (softer material undoubtedly).
For good or bad I tend not to use precise measurements and simply suggest "it's close enough" (my wife states it is "The Tao of Doug"). Well, what's 1 or 2mm off, going to make a difference.... Obviously no real planning and certainly missteps in the design and execution. I probably should fill in some of the corners and such but I tend to get too excited or impatient or dis-inspired to bother. When the rest comes together I regret the negligence. The tao-ism it must be said. However, it is the old-timey way and inexpensive, and it may be said in a sadistic way, fun part of the hobby.
