Usually clans that specialize in a certain area, (that are well-established with skilled members) are the place to find users with high skill levels in building.
C, Gentlemen with Monocles, NWB, and BAN all have members which are required to build at a high quality standard.
For instance, BAN specializes in creating starships, for which - not to sound conceited - we strive for the highest quality. Ask us for a house, however, and you might find that we'll have to put it on an asteroid to make it with any amount of "quality."
Likewise, you may notice that people have different building styles.
