Dutch architecture firm Hofman Dujardin has just designed BloomFrame, a window that you can convert into a balcony. It's like having a convertible in your own home. This is a great idea for those of us who like to practice our barbecue grill artistry, but are reluctant to do so within the confines of our apartments.
Since these window/balconies can be installed in existing buildings, soon it may be time to start pressuring that landlord of yours to put balconies everywhere. This might be a big hit with smokers. If this technology catches on, maybe someday we can all dine or toke al fresco.
