One of the most exciting projects happening at Google (GOOG) right now is Project Ara, the bullid-it-yourself smartphone designed by Phonebloks.

Apparently Google is already thinking about commercialization and production, with Project Ara Director Paul Eremenko revealing that Google will use the same sort of buying interface they use for Google Play. This will allow the user to buy and sell components on the storefront.

These different components will be sold by manufacturers and will have scored reviews, similar to how PC components are sold. Users will be able to choose brands, size, design and price in order to build their perfect smartphone.

Eremenko did not give a time frame on when Project Ara will become a commercial product. Google has said in the past they want the project finished by 2015, one of their "two-year cycles" of development, before moving onto something else.

Google has some of the best engineering minds on Project Ara, including ex-DARPA engineers who have come to work on the modular smartphone. This is an ambitious project, not only on the front-end, but to develop a smartphone capable of removing all parts without significant problems is a technical achievement.

Project Ara, like Google's other ambitious projects, remains for the most part behind closed doors. Phonebloks gave one preview of the facility and some of the new engineering changes on the modular phone - but we still don't know the specifics on how the phone builds itself.

The full video interview is below.
