ᐅ Completed large garage: Wood or concrete? What are the costs?

Hello,

I’m currently researching garages. Since we will most likely be building a timber frame house, I am generally open to a wooden garage as well. The garage should be 6x9m (20x30 ft) in size, so a large space with a sectional door, plus a separate storage room with doors leading both to the garage and to the garden, including a window and electrical outlets. Ideally, it should be insulated, with a flat roof without greenery. We are building without a basement and therefore want to plan for a sufficiently large storage room inside the garage. If there are any users who have built a similar garage, it would be very interesting to know the total cost including the foundation. Unfortunately, I have no idea what price range this would be in or the differences in price and quality between wooden garages and precast concrete garages.

Thanks
