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

The house is about 520 square feet, and there’s a separate sauna building with a guest bedroom, which is under 200 square feet. The project cost just over $250K—about 5 percent under budget. "Sticking to the budget is one of my favorite challenges," says Jussi-Pekka. "With my long history in real estate, I understand the importance of keeping costs low, even if I never plan to sell this house. You never know what life brings, and it’s always wise to build with future value in mind."
