This modular (built in July 2013) is meant as one of the famous Painted Ladies in San Francisco, the idea being borrowed from Henrik Hoexbroe (http://www.mocpages.com/moc.php/327477) who has built a whole row of them. In a larger scale you can find them in Legoland California, too. The future town will probably have some Frisco stuff in it, at least theres already a very fine Cable Car built by Altezza which goes quite well with it (https://www.flickr.com/photos/78251455@N06/9067238173).
About this creation
There is no interior, but, since cars are always important, a working garage door. The garage even fits the full-size cars. Due to the SNOT road and pavement system there is no usual baseplate, so a width of 21 studs is no problem. Building in an odd width widens the range of possibilities, e.g. you can have cheese on both edges as you can see in the frieze at the gable.
The pillars at the bottom of the staircase are shortened versions of the ones used at the Gas Station.
The curtains at the windows of the second floor are made out of bridal veils (of a bride collectable minifig).
The garage door has a new mechanism using minifig hands which allows any width (see below).
Many thanks all, glad you like it! @sam: I can see what you mean, definitely ... ;-) @Topsy: Bay window - didn't think of that, great! @frank: Thanks a lot. Glad you like the garage door, too! @Alex: That's nice about building larger stuff - there's so much room to try things ... ;-) @Vinny: On the other hand there's a model house now - only the facades differ. @clayton: Glad you like it! @Cheryl: Glad you like it. Since this is rather meant to be displayed there's no use building an interior nobody can see. But I'll surely do that when building something with an open back.@Sven: Glad you like it bud! @adam: Glad you like it!
