Anybody want to advise me on my loft?

[Renovirgin2018]

Hi all. We have our loft conversion plans in which is super exciting but I am just wondering if there are any tips you lovely mumsnetters would like to share? Also, what should I do with the awkward L shaped space in the bottom right? (Keeping in mind the sloping ceiling)

Ours is similar shape, except no en suite. Honestly, just make the sticky out bit a big storage cupboard - unless the roof height is particularly high, it will be dead space - we had visions of putting a small desk or chair there but realistically it’s not practical. The other side which we made a cupboard is soooo much more useful - has swallowed loads of stuff from the rest of the house.
