Lorcan O'Herlihy Architects (LOHA) is an architecture and design firm based in California. Their work is stunning (and their website is pretty nifty too!). I've only checked out their residential designs so far and had a hard time choosing a favorite, but the exterior (above) and view! (below) of the Lexton MacCarthy Residence (click the Lm on their 'periodic table of elements' on their website) really caught my eye.
Also of note: I'm not one for subdivisions, but their 12 Houses plan (click Hv) gives cookie-cutter urban sprawl eyesores reason to hope.
