The phone booth for office calls that stay private

A phone booth is a free-standing, soundproof cabin for one person that simply stands in the middle of your floor. Some people call it an office phone box, and that's fair enough — ours is just built for the modern workplace: no handset on a cord, but ventilation, light and a power socket inside. Instead of hunting for a free meeting room or walking out to the corridor to take a call, you step in, close the door, and the noise of the open-plan floor stays outside. It's up within hours, with no refurbishment and no builders: plug it into a socket and it works.

Four reasons to put a call booth on an open-plan floor

Open-plan saves space but takes away the quiet you need to talk. A booth for calls gives it back — here are four reasons it solves the noise problem.

Private calls in open-plan space

The phone booth contains your voice so well that the conversation is inaudible a metre from the door — nobody at the neighbouring desks is distracted, and you speak freely.

Full focus on the call

The booth switches off the background hum of an open-plan floor, so you hear the other side clearly even through long Zoom and Teams calls.

Installed without building work

The compact structure goes up in 2–3 hours — no drilling, no dust, no permits. All it needs is a 220 V socket nearby.

Moves office when you do

The phone booth can be dismantled, transported and reassembled somewhere new — it isn't fixed to the floor or the walls.

Sound insulation up to 35 dB: how the phone booth works

The sound insulation of a phone booth comes from multi-layer panels that absorb outside noise and keep the conversation from leaking out. The level depends on the model — 25 dB on Lite, up to 35 dB on Premium. For daily video conferences on an open floor, 35 dB is the sweet spot: the microphone picks up no stray voices, and the person on the line hears only you.

Solo Lite
25dB

Absorbs speech noise and the general chatter of an open-plan floor — the best balance of quiet and price for short calls through the day.

Solo Premium
up to 35dB

Certified insulation to ISO 11957: the conversation inside is inaudible a metre from the booth, and office noise no longer gets between you and the person on the line.

Common questions about phone booths for offices

An office phone booth is a compact, soundproof cabin for one person — built for calls, video conferences and short bursts of focused work in open-plan space. People also call it a call booth, an office phone box or a phone pod. It's installed with no building work and creates private space exactly where the floor plan doesn't provide any.

Yes. "Call booth" and "office phone box" are everyday names for the same product we call a Silentbox phone booth. Unlike the classic telephone booth on the street, ours is a soundproof cabin built for the workplace: SMART ventilation, lighting and a power socket inside, assembled in 2–3 hours without any refurbishment.

No. Solo Premium cuts sound by up to 35 dB (certified to ISO 11957) — the conversation is already unintelligible a metre from the door. Solo Lite gives 25 dB, absorbing speech noise and open-plan chatter, which is the right level for short everyday calls.

It depends on the model: Solo Lite is the accessible class for straightforward calls, while Solo Premium brings certified 35 dB insulation for daily video meetings. Current prices for every model are in the catalogue above; if you're ready to buy a phone booth, we'll put together a quote for your office within one working day.

Solo Premium measures 1050 × 1100 × 2200 mm and weighs around 330 kg. It's sized for the standard goods lifts and doorways of office buildings, so it can be taken up to the higher floors. Exact dimensions come with your quote.

No. The booth goes up in 2–3 hours — no drilling, no dust, no construction permits. All it needs is a 220 V socket nearby; ventilation and lighting are already built in.

Yes. The certified insulation of Solo Premium (35 dB) shuts out open-plan noise, so your microphone and camera pick up only you, not the conversations around you. SMART ventilation refreshes the air without the drone that would otherwise sit under a video call.
