Light that vanishes when it’s off

At Skyhouse, a white penthouse with framed views, Tillotson hid the light in glass-fronted troughs and two-inch ceiling reveals.

Skyhouse is a penthouse pied-à-terre in New York by David Hotson Architect, with interiors by Ghislaine Viñas and lighting by Tillotson Design Associates1. Its all-white rooms pull in daylight, with pops of colour in the furniture and art1.

The brief for the lighting was that it had to look seamless during the day as well as at night1. So the ambient light comes from backlit LED troughs with white glass fronts, placed around the apartment. When they are off, they disappear into the walls and ceilings1.

Good lighting isn’t always about adding more light fixtures or making spaces brighter; it’s about designing lighting that is intentional and purposeful.

Even the ceiling does two jobs. Dark reveals barely two inches wide conceal the air-conditioning, the studio says, so nothing interrupts the white planes1.

From the project

The press the studio lists for the project gives a sense of the apartment’s scale and character: one headline calls it ‘the NYC penthouse with an 80-foot slide’1.

Tillotson’s approach here is the domestic version of this issue’s idea. The light is neighbourly to the architecture: you notice the rooms, the colour and the view, not the fittings.

At a glance

  • Backlit LED troughs with white glass fronts, invisible when off.
  • Two-inch ceiling reveals hide the air-conditioning.
  • The lighting had to work by day as well as by night.
