Designed alongside your decorator, not after.
Six designers between us spent fifteen years lighting hotels and restaurants before we started on homes. The methodology came with us.
Open for autumn 2026 commissions
A quieter kind of smart home.
A six-person studio of designers and engineers, working on lighting, audio, climate, security, EV and integration projects across London and the Home Counties. We design systems you'd rather not notice — until you'd hate to be without them.

EV & energy

A note on the studio
We started Lumen House in 2017 with one rule.
The technology you live with should feel like architecture, not like electronics.
A house full of glowing screens, plastic buttons and apps that need software updates isn't progress.
It's just another tax on your attention. We do the opposite: a single switchplate in brass, one app you barely open, a system that wakes itself up before you do.
Systems
Six rooms. Six conversations.
Each system is designed alongside your architect, decorator and electrician — not bolted on at the end. Pick a room. We'll show you how it should feel.
i / Living & kitchen lighting
A single switchplate in brass, six scenes underneath it.
ii / EV & whole-home energy
Hide the charger. Show the house.
iii / Cinema & multi-room audio
Speakers you sit on, not next to.
iv / Climate & underfloor
Warmth in eight zones, governed by one thermostat.
v / Security & access
Doors that recognise you, not your phone.
vi / Integration & control
One platform underneath. Six interfaces above.
What we work in
i — Lighting
ii — Energy
iv — Climate
v — Audio
vi — Service
Materials matter. Wires matter, too.
The brand decisions matter less than the labour behind them. We're full Crestron and KNX programmers in-house — we don't sub-contract the brains of your house.
£0
Average household generates surplus by year three.
Solar, battery, EV, dynamic tariff. A single Lumen dashboard that runs the lot.
Zoned to the way you actually live.
Underfloor, radiator, MVHR, blinds. All speak to each other.
Sonos Pro & Lyngdorf, properly installed.
In-wall, in-ceiling, in-rock if the brief demands it. Cabling pre-loomed.
A direct line, for the life of the system.
You ring a person. The person knows your house. It's that.

As seen in
— House & Garden, March
"Quietly the most considered home-automation studio working in London right now."
— Wallpaper*, October
"A six-person studio whose lighting design rivals practices three times their size."
— Vogue Living, January
"You don't notice their work. That's the entire point."
"They sat with our architect for fourteen months before installing a single switchplate. The result is the most thoughtful technology in any house we've owned."

Our books open for autumn 2026 commissions on May 12.
We take on four to six whole-house projects a year. For partial commissions — a cinema, an EV install, a single lighting scheme — we can usually find a slot within the quarter.
