Trouble with flat roofed houses like ours is you miss the storage space that most conventional houses have in their lofts.
We have coped with this to a limited extent by using the space in the coal truck and the void below the roof room floor. Mainly though the spaces inside the three bays of the navvy hut have become cluttered (a serious understatement).
I do not know why I have not thought of it before but I am fitting a floor below the pitched roof of the navvy hut which is creating an enormous loft. There is a good six feet of headroom under the apex.
Here is the hut before it was taken to pieces by Network Rail at Appleby. If you draw an imaginary line between the gutters you get an idea of the size of the resulting loft. Of course, not all of the space is usable because of the sloping roof but well over half of it is.
Not only that, I have dropped upon nearly 40 sturdy lidded rectangular buckets from a local farm. Into these will go the odds and ends in their various categories for ease of retrieval when needed. That at any rate is the theory. I am mindful of a comment made by darling daughter Lorna last weekend. "Don't put all your rubbish up there Dad, please. When you kick the bucket it will be me who has to get rid of it all."
True, but it will at least all be in red buckets for ease of disposal.
A proper staircase will give access to the loft, which is already lit with LED lights.
