The space you want to prepare for framing can be a dedicated area or temporary set-up.
The key element you will need is a solid work surface, approximately 120cm x 90cm (4ft x 3ft), clean and grease free (an mdf board over a table is very satisfactory)
Good lighting over the work area is important and I suggest you consider a desk lamp (though not essential) for close up work and inspecting quality of cuts, etc
In addition, I recommend an adjacent space - either a shelf or side table - for tools and accessories while you are working, so you can keep that main work surface free of clutter.
To give you an indication of storage for some of the larger items, the longest item is the safety ruler at 92cm, and all the boards can all be cut in half to become 60 x 80 cm sheets. Storage can be flat or upright.
Picture framing is not messy or noisy so it can be carried out in any clean environment.
