Light reflecting off the ceiling will make the space feel taller. Downlighting is practical, but if used on its own the ceiling will appear relatively dark vs the bright floor, and therefore lower. An interesting design will therefore look at all the fixing points available: floor, walls, joinery and ceiling to incorporate ways of washing light upwards.
Where downlights are used they should be used to bounce light off vertical surfaces (walls, joinery, artwork) rather than just down in the centre of the room, as again this will “lift” the room.
In older buildings ceiling void spaces are often limited. Ceiling surface mounted fittings close to head height can be uncomfortable and visually intrusive. Alternative fixing points therefore become even more important.
In this Yorkshire Dales cottage we used low glare uplights as the primary light source in this connecting room. It makes the space dynamic rather than flat and the light reflecting off the low beamed ceiling gives plenty of illumination.
