Ceilings that hold the night sky.

Fibre-optic starry ceilings, individually placed. From 1,000 points for a bedroom to 30,000+ for a dome. Twinkle, drifts, constellation maps, slow-cycle colour — all programmable from an iPad.

01 — How it works

A forest of glass strands, lit from a single engine.

01

The light engine

An LED source sits hidden in an adjacent cupboard or ceiling void. It feeds a bundle of 0.5 mm polymer optical fibres — no electricity ever enters the ceiling. Silent. Cool to touch. 60,000-hour life.

02

The ceiling build-up

Fibres are drawn through a 40 mm acoustic plaster or fabric-wrapped panel, terminated flush, polished, and sealed. From below, each fibre is a single point of light — indistinguishable from a real star at 3 m.

03

The choreography

A DMX controller programmes twinkle patterns, meteor sweeps, slow colour shifts, and scene recalls. Integrates with Control4, Crestron, Savant or Lutron. Wake the ceiling with a voice command.

02 — Why these, and where

Four reasons they work — and four rooms they work in.

01

Retrofit-friendly

Only 40–60 mm of ceiling build-up. Installs over the existing ceiling in most rooms — no structural work, no re-plastering walls.

02

Silent fibre-optic

One cool-running LED engine drives every point of light. No hum, no flicker, no heat, no LEDs failing in the dark above you.

03

DMX scenes

Fade, colour-shift, breath-dim, shooting stars. Tied into your home automation or run from a single wall dimmer — your call.

04

Invisible finish

The plaster, tension or timber finish you choose stays the hero. Fibre terminations are sub-millimetre; visitors never notice them unlit.

Suitable for any space
Bedroom with starry ceiling
Most common

Bedrooms & children's rooms

Warm-white starfield with a slow breath-dim. The ceiling fades with you as you fall asleep — and wakes quietly at dawn if you want it to.

Living room with starry ceiling
Statement

Living rooms & cinemas

RGB scenes that move across the evening — sunset, indigo, deep night — or a fixed constellation overlay tied to the screen and the sound.

Pool and spa with starry ceiling
Wet areas

Pools & spa

Moisture-rated fibre and sealed terminations. A starfield that reads across the water and reflects on the surface. Installed in a dozen villas on the coast.

Hospitality space with starry ceiling
Commercial

Hospitality & commercial

Restaurants, hotel lobbies, spa lounges. Calm single-colour fields for a quieter architectural read — designed to work across the whole service of an evening.

Common questions

Starry ceiling FAQ

More questions across all services on the full FAQ page.

01

Fibre-optic or LED?

We build almost exclusively in fibre-optic. A single light engine drives every point, so the ceiling never has flicker, hotspots, or individual LEDs failing behind the plasterboard. LED is only right for architectural pattern work where you want animation per pixel.

02

How much ceiling height do I need?

A fibre-optic ceiling adds 40–60 mm of build-up for the fibre layer and termination plate. If we're adding a sky plenum or integrating with acoustic treatment, expect 80–120 mm. Anything above 2.5 m finished height is comfortable.

03

RGB, white, or something in between?

Most bedrooms we do are warm-white with a slow-breath dim. RGB is worth it when you want to move through moods (sunset → indigo → deep night) or you're doing a child's room with a specific story. Commercial work is nearly always single-colour for a calmer read.

04

Can you install over an existing ceiling?

Yes. Most of our installs are retrofits. We work over the existing structure with a shallow plenum, reroute any conflicting services, and make good. A bedroom retrofit typically takes 5–7 working days with the room out of use.

05

What maintenance does it need?

The fibre layer is sealed for life and needs nothing. The light engine has a replaceable LED module (every ~15–20 years of normal use) and is mounted in an accessible panel above a cupboard or in a plant room. We include a first re-tune visit in year two.
