Discreet, Powerful Sound for London Flats, Townhouses and Period Properties

How to get genuinely good multi-room audio into a property where every speaker, cable run and rack has to justify its presence

London presents a constraint that most other markets don’t have to design around quite so seriously: space, and the rules governing it. A mansion block apartment with no scope for new cable routes. A Georgian townhouse where the freeholder’s lease prohibits structural alteration. A listed building where even drilling a wall needs sign-off. A new-build flat with floor-to-ceiling glazing on every external wall and nowhere obvious to hide a speaker. This page is about what good multi-room audio actually looks like once those constraints are taken seriously, rather than designed around as an afterthought.

The Lease and Listed-Building Problem

A meaningful proportion of our London clients live somewhere with real restrictions on what can physically be done to the property — a lease that prohibits altering communal risers or structural walls, a listed building where the local conservation officer has a say in anything affecting the original fabric, or simply an interior so recently and expensively finished that nobody wants new cable chases cut into it. None of these rule out a genuinely capable audio system; they change how it has to be delivered.

Wireless backbone technology — Crestron’s own wireless lighting and control protocols, paired with high-quality wireless or minimally-wired speaker solutions — lets us deliver a properly zoned, properly controlled multi-room system using existing power circuits rather than requiring new low-voltage cable runs through walls a lease won’t permit touching. Where some cabling is unavoidable, we route through existing risers, under-floor voids accessed from below rather than above, or furniture rather than structural fabric. Lutron RadioRA 3, fully wireless, follows exactly the same logic for lighting and is frequently specified alongside an audio retrofit in precisely these situations.

Plastered-In and Architecturally Invisible Speakers

For London interiors finished to a high standard — and a great many of the properties we work in are — visible speaker grilles are simply not acceptable, regardless of audio quality. The answer isn’t a compromise on sound; it’s a different installation method entirely.

We regularly plaster speakers directly into ceilings and walls, finished completely flush and invisible once painted — a technique we’ve used on multiple Belgravia and Kensington projects where the brief was explicitly that no visible technology should exist anywhere in the room. Subwoofers go into existing joinery, behind bookshelves, or within custom cabinetwork built specifically to house them rather than sitting exposed on a floor. The test we hold every London installation to: a visitor with no prior knowledge of the system should not be able to identify where a single speaker is, even standing in the room with the system switched off.

The Townhouse Problem — Four Floors, No Wasted Space

London’s classic Georgian and Victorian townhouses present a specific zoning challenge: four or five narrow floors, each one a genuinely different room type — a formal reception room, a family kitchen, several bedrooms, sometimes a basement cinema — stacked vertically rather than spread across a single floor plate the way a villa or a chalet would be. Running an audio backbone through a townhouse means navigating original staircases, frequently-listed cornicing and ceiling roses, and very little spare riser space compared to a new-build.

Our approach is to centralise source equipment in one location — typically a basement or utility cupboard — and distribute audio and video to every floor from that single point, rather than scattering equipment rack-by-rack through the building. This minimises the number of locations requiring cable access and keeps the visible footprint of the system to almost nothing on the floors where the family actually lives. Our Baker Street project — eight audio zones and eight HD video zones across a townhouse, with every system accessible from a single touchpanel — is the clearest example of this approach in our portfolio.

Apartments and the New-Build Glazing Problem

Modern London apartment developments frequently feature floor-to-ceiling glazing on one or more external walls, which solves a daylight problem and creates an acoustic one — hard, reflective glass surfaces opposite a single remaining usable wall, with nowhere obvious to position a balanced speaker layout. We address this with careful positioning that uses the available wall and ceiling space deliberately rather than defaulting to whatever’s easiest, alongside soft furnishing recommendations — curtains, rugs, upholstered furniture — that meaningfully reduce the reflections a glass-heavy room otherwise suffers from. A soundbar-and-subwoofer combination, properly specified and positioned rather than simply placed beneath the television, frequently outperforms a more expensive but carelessly positioned surround system in exactly this kind of room.

Frequently Asked Questions — London Multi-Room Audio

Can a good audio system be installed without breaching a lease’s structural restrictions?
Yes. Wireless backbone technology and careful routing through existing risers and voids lets us deliver a properly zoned system without new structural cable chases in properties where the lease prohibits them.

Can speakers be made completely invisible in a finished London interior?
Yes. We regularly plaster speakers flush into ceilings and walls, and integrate subwoofers into existing or custom joinery, so no visible hardware remains once the room is finished and painted.

How is a four-floor London townhouse wired for whole-home audio without disturbing original features?
By centralising source equipment in one location and distributing to every floor from that single point, minimising the number of locations requiring cable access through listed cornicing or original staircases.
