This is the home of Liza Giles, a stylist for Designers Guild. We love the style - but what really jumped out at us when we saw all the images together on decor8 was the way Giles hung the artwork - big, unruly, tight clusters of framed and unframed pieces, creating almost a whole new singular piece out of multiple small ones. We like it. It looks modern and old fashioned at the same time...another example below:
We'd have to say the rule for this type of arrangement is essentially "throw out the rules" - the look is organic, a bit wonky and unafraid - it's a "just go for it" thing.
