Dwell’s recent issue devoted to modern pre-fab homes highlighted  Blu Homes, the Waltham, Mass.-based builder of modern, green homes designed with foldable steel-frames that allow for easy transport and open floor plans. If you have been thinking about a pre-fab and want to see one in person, you have an opportunity this Sunday to get a sneak peek of the company’s first Breezehouse in Maryland. The house is located on beautiful Round Bay in Severna Park and will be open for the first time to the public this Saturday and Sunday. If you want to be one of the first to view the model home, click the links to register for Saturday or for a tour on Sunday.
