Hidden Home Technology designs and installs international award-winning home cinemas, hi-fi listening rooms and smart home systems across South Wales. We cover the region from Swansea, the Mumbles and the Gower in the west to Newport and Monmouthshire in the east, with the Vale of Glamorgan in between. Cardiff has its own page: home cinema installation in Cardiff.
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
Client Quote:
“We could not be happier with our home cinema, it has far exceeded our expectations (which were already set very high given their fantastic reputation!).
Dan, Jess and the team were an absolute pleasure to work with and gave us the highest levels of support and customer service throughout the project. Their attention to detail in the design, execution and after care is genuinely second to none and their passion and commitment to giving us the best room possible was really clear.
We won’t be using anyone else in the future and are already excited about working with them again.” — [Shelley & Alan, Wales]

An attic cinema in Wales
An unused attic storage room became a dedicated home cinema. We handled all of it, from the interior design and the build to the air conditioning, the lighting and the decoration. The acoustic treatment is designed to work down to 40Hz, and the picture comes from an Epson LS12000 projector on a 3 metre acoustically transparent screen. See the attic cinema in Wales

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.

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.
We work across South Wales, including Swansea, the Mumbles and Gower, Newport and Monmouthshire, Cardiff, Cowbridge, the Vale of Glamorgan and Blackwood, as well as properties along the M4 corridor.
Yes. We have experience with older stone properties and character homes, as well as modern coastal houses. The aim is to integrate cinema, audio, lighting and control discreetly, without losing the character of the building.
Yes. For cinema, hi-fi and listening rooms we can look after layout, interior design, acoustic treatment, lighting, equipment specification, installation and calibration.
Yes. Cinema, hi-fi, lighting, blinds, security, entry systems and wider AV can be brought together into a simple control system, with app-based and one-touch operation where appropriate.
The first step is a conversation about the property, the rooms involved and how you want to use them. From there, Hidden Home Technology can advise on feasibility, budget range and the most suitable design route.
From Cardiff to the Gower, projects that start with a cinema room usually grow into the whole home — lighting control, multi-room audio, heating, shading and security under one system. See our smart home installation in South Wales page for what a whole-house system includes.
