I have clean slate in a mid terrace Victorian loft conversion. Originally I wanted to put in recessed down lights but have since discovered it's not recommended for a cold flat roof with Celotex. I'm considering wall lights only. Has anyone done this or have any examples? The finished ceiling height is around 2100mm. It's a dormer conversion and will have a bathroom so main area will be L shaped with a sloping ceiling to the dwarf wall.
