Last year Lego introduced the Creator Modular line. It seems like the concept was well received as all Creator houses are modular in the current Lego catalogue (2018 January – June).
While I’m not entirely convinced about the building technique, most of the houses look great.
When my daughter had to stay home sick a couple of weeks back, my wife decided to build 31081 Modular Skate House to keep them entertained.
