Lego lends itself to modern architecture surprisingly well. The geometric and clean designs can be replicated with SNOT building techniques. A great modern style Lego MOC is the Daisy Hill House created by Sarah Beyer. The actual build is unfinished but some of the interior rooms are done. A bedroom, kitchen, and upstairs landing have been completed. The results are amazing. The landing uses a variety of patterns and geometric shapes. The Lego bookcases look very good, and OSHA would approve of the the railing. The bedroom features a lot of natural light, achieved by building the windows sideways. The plant adds some life to the room.
Downstairs is an open floor plan kitchen. The different patterns on the walls, the windows, and the grid aligned floor all combine well. The sofa is nice and clean, and the houseplants look happy. This modern house would make many a Lego Minifigure happy!
