Budget Breakdown: This $250K Prefab Cabin Is an Ode to the Finnish Sauna

While the house is prefab, the interior and finishes are almost entirely designed by Jussi-Pekka. One of his favorite custom-made elements is an LED light he designed for the window wall on the view side—an idea inspired by the lighting strips in planes that guide to emergency exits. "It’s there to highlight the importance of the glass wall that faces one of the most important aspects of the house: the view," he explains. The sideboard was inherited from Jussi-Pekka’s grandparents.
