Quoting Hugh Brown Brown
Could the best Lego builder in the world please post a list of instructions? Anyway great model.
Sorry I built this one "freehand"! I just started with my grungiest 1x2 white bricks (you know those not-so-white anymore, dirty ones) but as, concrete blocks, they look great.
You also asked (on September 29, 2009) about instructions for my Ghostbusters' Headquarters http://www.mocpages.com/moc.php/106364 see your comment...
and my reply...
I did post those instructions here:
you could try building the BG's HQ
You could also leave feedback there if you liked the instructions!!
You can also build your own LEGO Modular House:
(from: http://www.brickwiki.org/wiki/Modular_houses_standard )
* Baseplates - Buildings in this standard are built on multiples of 32 stud x 16 stud baseplates. Usually used singly or in pairs, there is no stated limit other than the space available.
* Connnection - Joining the adjacent modules are two technic bricks with a hole (3700) on each side of the building. These bricks are placed 9 studs from the front and back leaving 10 studs between them.
* Build area - The standard incorporates sidewalks of 8 studs at the front which leaves a single stud in front of the connection bricks. If a similar alleyway is left at the back that creates a 16 studs wide x 16 studs deep area for building. The alleyway is not required but eliminating it altogether may interfere with cooperative displays.
Try to keep the fašade or face of your buildings 7 to 9 studs back from the edge of the base plate. This allows room for a sidewalk and ensures that most buildings will be on the same plane. from: LEGO.Com
Applying these guidelines to both front and back leaves a possible build area (on a single 16x32 baseplate) of up to 16x18. Using multiple baseplates in a single building creates a maximum build area of 32x18, 48x18 or even larger.
* Height - The recommended height is around 9 bricks per story.
* Sidewalks - The surface of the sidewalks in all sets released in the series have been created using tiles. Using plates with studs showing is more attractive to many builders who espouse a studs showing aesthetic and/or appreciate the flexibility of fig and detail placement possible with exposed studs.
hope this helps
