Thanks a lot for the project hopes it meets your standards. Am sorry just found out that you no longer need the garage which I have designed already ,and you still need pergola which I just noted now which was not in the initial plan, but as for pergola ,you can just have it adjacent to the opening, its late I can not adjust it as time is not on my side. You can just do without it please. For the Sauna, you can select your preference from the link below.https://www.alibaba.com/product-detail/House-Design-Low-Cost-Infrared-Sauna_60582407896.html
