I haven't found something close to Crate and Barrel. Some people may recommend GOD, but in my opinion it's not the same. Also like pp recommended TK and S are not even close in my opinion. I love Room & Board and Crate & Barrel, but not really something similar in HK. However you can have a lot made / copied here, so you may want to bring some catalogues.
Oh, and Tree is maybe close to what you're looking for ... a lot of teak, straight lines, modern. Definitely closest to my 2 favorite stores. However we shipped a lot from the US so I only wanted some antiques to match the modern part. Tree has a website, so just google. They have a Central store and one in Ap Lei Chau on the 28th floor (very large). Not cheap, but their sale is quite good now and quality better than IKEA and a little different as well!
