Their primary masterpiece is Minibyen, a scale model representing the historic grid town of Kvadraturen and the old wooden neighborhood of Posebyen as it looked in the late 1890s. You can see their incredible work on display outdoors in the dedicated Minibyen section at Kristiansand Museum (located on Øvre Kongsgård). Visitors can walk through the miniaturized streets like Gulliver, admiring detailed 1:10 replicas of iconic historic landmarks, old butter factories, stock exchanges, and entire wooden blocks of Posebyen.
Beyond their permanent home at the open-air museum, select models and creative elements crafted by the mini-builders have also been exhibited and showcased within public municipal spaces, including Kristiansand City Hall (Kristiansand rådhus). These exhibitions in civic buildings have helped bring the history of Kvadraturen directly to local residents, municipal leaders, and visitors right in the heart of the city's administrative center.
