Nelse Design + Build constructed their first house using SIPs for the walls and roof:

br: 4
bath: 2.5
From their Green Cubed website:
The core idea of this project is relatively basic; develop a home design and building system for urban infill lots (in this case, Seattle) that is modular enough to maximize design and construction efficiencies, adaptable enough to respond to each unique site and occupant, and sustainable enough to provide a healthy, environmentally friendly, and energy efficient home for generations of urban dwellers.
A slide show is also available on the site.
