We need to finish our timber-framed, attached to the house, garage.
The walls are 140mm studs with 120mm insulation which was fitted by mistake in the TF factory.
We have considered plasterboard, plastering and paint, but this is quite an expensive way to finish the garage. Then we have OSB board, cheap to buy and easy to install, but with a utilitarian appearance.
Are there any other options we should consider - we want it to look nice for the least possible money (who doesn't).
Here is a picture of the wall.
Thanks
