My house ale only takes 7-10 days then can be bottled. 2-3 weeks lets it clear a bit more but cloudy beer doesn't bug me, I am not entering contests! A PID controlled fridge works well too for fermenting in. Mine was set at 62 and the fermenting wort might reach 68 which is fine for the yeast I use. IPA's are also fast fermenters unless it is an IIPA(ABV over 7%...) and can often be bottled at 7 days if you are not dry hopping in the fermenter.
