The space is the upper floor of a garage and has natural as well as artificial light. The staircase is quite narrow and steep so long, bulky or heavy items would not be suitable. It would not be heated in the winter. It is though completely dry and well insulated, and it has a strong floor. It has actually been designed as a children's playroom or office but is not used for either at present. From the photos you can see that the side wall is only 1m high rising to 2m. Only the space on the right side in the first photo is available as I am using the space on the right.
