for something that is for a game environment i'd say that's a lot more faces than you need
the main building itself you could get away with by just straight out transformed cubes and then if the windows need to be indented then do that by normal maps, provided the game engine you're porting to supports that
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
