whilst i can't answer your question (because i've never gone to look for buildings in maya) i gotta ask something of you...
why are you looking for a building in maya?
whats wrong with using the 3dsmax stuff you find?
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Objective C, C#, Java, MEL. Python, C++, XML, JavaScript, XSLT, HTML, SQL, CSS, FXScript, Clips, SOAR, ActionScript, OpenGL, DirectX
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
