Hidden Home Technology designs and installs international award-winning home cinemas, hi-fi and smart home systems for houses across Cornwall. Many Cornish properties are more than one building. A farm or a coastal house may come with holiday cottages, art studios or a barn, so we plan the network, the audio and the control for the whole property and every building works as part of one system.
We design and install complete cinema rooms. The layout, the acoustics, the equipment and the interior are planned together, so the finished room performs well and is a comfortable place to spend an evening.
Custom room design and layout planning
Acoustic treatment and soundproofing
Premium projectors, screens, and audio equipment
Lighting and control designed with the room
Calibration of the picture and sound once the room is finished
For music enthusiasts, we design and install high-performance hi-fi and listening rooms:
Full acoustic treatment down to the low bass region
Custom speaker placement and acoustic tuning
High-end amplifiers and sources for pristine sound
Control through the same system as the rest of the house
We bring intelligent control to your home, combining convenience, security, ergonomics and style:
Whole-home automation for lighting, climate, and AV
Voice and app-based control
Energy management and smart security integration
Discreet installations that preserve your home’s aesthetic
We transform properties all over Cornwall and the surrounding area: automated lighting, curtains and blinds, integrated audio and video system, entry systems, CCTV — all managed from a single app.
Expertise in Cornwall properties — from coastal farms and clifftop holiday homes to townhouses in St Ives and country estates around Truro, often with multiple outbuildings, art studios and detached guest cottages to integrate
Systems designed around the house and the way you live in it
Discreet and professional installation with minimal disruption
Award-winning: four URC Unsurpassed awards for Best International Installation since 2021
A URC-controlled estate at St Mawes
At St Mawes on the Roseland Peninsula the estate runs on URC control. Mirror televisions are concealed in the living room and the master bedroom, and each has a discreet 5.1 surround sound system that sits invisibly behind the screen.
A farm near St Buryan
On the Land’s End peninsula we supplied a Chord Electronics hi-fi system with Nordost cabling to a farm near St Buryan. We extended it into a multi-room audio system that reaches the main house, the art studios and the holiday homes, all carried on an estate-wide Wi-Fi network that we designed and installed.

Bring serious cinema engineering into your home. Our team designs and installs dedicated rooms with proper acoustic treatment, high-performance projection, and control that works with the rest of the house.
A purpose-built cinema room behaves differently from a living room with a TV in it. Acoustics are designed before equipment is chosen; light is controlled before screens are sized; the result, finished, is a room that disappears the moment the film starts.
Multi-room audio, garden speakers and simple smart-home control discreetly integrated into an open-plan home in Englefield Green, Surrey.
A Cotswolds home cinema set inside a period country house, with whole-house audio kept out of sight everywhere else.
A garden room turned dedicated home cinema in Gloucester. The client supplied their preferred audio kit; we delivered the room around it — interior and lighting design, acoustic treatment effective to ~60Hz, a floating front-wall feature, and a 7.1.2 Atmos layout calibrated in-room with Marantz processing.

Every project is specified around the room, the building and the level of integration required. Dedicated-room projects with a more focused scope typically start from around £35,000 including VAT. That is not a minimum spend for surround sound or hi-fi installed in an existing room, which can cost significantly less. A complete designed cinema room is a different scope: our serious cinema guide is £80,000–£120,000 including VAT, with reference projects around £200,000–£400,000+. Exact inclusions and costs are agreed in your quotation. Whole-home smart systems and hi-fi projects are quoted individually.
Yes. We regularly design discreet systems for older and character properties, including coastal homes, farms and country houses, with careful planning to preserve the building’s appearance and fabric.
We work across Cornwall, including St Ives, Penzance, Truro, Falmouth, Newquay, the Roseland Peninsula and the Land’s End peninsula, as well as surrounding areas where the project is a good fit.
Yes. Many Cornwall properties include outbuildings, barns, art studios or guest accommodation. We can design estate-wide networking, Wi-Fi, audio, video and control systems so the spaces work together reliably.
A smart home project can include lighting control, automated curtains and blinds, multi-room audio, cinema systems, entry systems, CCTV, networking and app-based control, designed to suit the property rather than dominate it.
Coastal builds and renovations in Cornwall often begin with a cinema or media room, then take on lighting control, multi-room audio, heating, shading and security as one system. See our home automation in Cornwall page for what a whole-house system includes.
