This 400 page paperback, The big unofficial LEGO Builder's Book: Build your own city, has just been published by Heel Verlag GmbH, I have yet to purchase. It's written by Joachim Klang and Oliver Albrecht who, according to the introduction, are active members of the German AFOL scene and 1000Steine.
It's divided into two sections. The first provides instructions and
inspiration for building a micro-scale LEGO city like that shown on the
cover. Most of the 30 instructions are for vehicles of some sort
although some small buildings and trees are also included. The second,
much smaller section, has instructions for five minifig scale
'professional models', four cars and a helicopter. (source: Brickset)
