How to make a media wall look better?
A media wall looks better when its proportions are right, not when more is added. The decisions that matter are made at framing: projection depth of 200 to 300mm, a recess cut to your exact screen, one material across the full width, and 100mm of Rockwool inside the framework. Paint and lighting come afterwards.
What is decided before the plasterboard goes on
Nearly all advice on this treats appearance as something you add at the end. The decisions that separate a wall you keep admiring from one that quietly irritates you happen at framing, and once the boards are on they stop being adjustable. Projection is the first. The framework comes forward 200 to 300mm from the existing wall, and pushing past that in a narrow room turns the feature into a box. Recess tolerance is the second. A screen sitting proud of its opening, or floating in an uneven gap around the bezel, is the most visible flaw a finished wall can have, and it comes from a recess cut to a generic size rather than to your set. Third is where the cladding stops. A slatted panel that dies mid-wall on a cut edge looks unfinished; one that returns into the reveal and lands on the cornice line looks built.
Paint, lamp temperature, shelf styling and handles stay changeable for as long as you own the wall. Depth, recess tolerance, shadow gap width, screen centre height, the reinforced ply behind the mount and the insulation inside the framework do not. Any advice that says a finished wall can be rescued with accessories is only talking about the short list.
The numbers to measure your own room against
Proportion advice means nothing without dimensions, so here are ours. Clapham Victorian front sitting rooms run 3.2 to 3.8m wide with a 1.2 to 1.4m chimney breast, which takes a 65-inch screen cleanly and will not take library joinery without the room closing in. Bromley 1930s living rooms at 4.0 to 4.5m carry 75 to 85 inch wall-to-wall, with the sofa 3.0 to 3.5m back. Edwardian breasts in Bickley measure 1.6 to 1.8m, wide enough to centre a big screen over a wide-format fire. Below 3m of wall, hold at 55 inch and keep the build shallow. Ceiling height governs the joinery: floor-to-ceiling shelving sits properly at 2.8m and above, and a Balham basement flat at 2.4 to 2.6m needs a slim wall-effect fire rather than a deep recessed one, because a full-depth recess in a low room swallows the room.
If your measurements fall between two bands, look at the configuration before committing. Our idea generator renders your exact spec as a photograph in ten to fifteen seconds, which tests a proportion faster than a mood board.
Why a media wall sounds cheap before it looks cheap
Knock on a poorly built media wall and it booms. A framework boarded and skimmed with nothing inside is a drum, and every bass note from the screen or sound bar excites it. That hollow resonance is what people are reacting to when they say a wall feels cheap, and no amount of oak or lighting corrects it. We pack 100mm Rockwool acoustic insulation into the framework as standard. It kills the drumming and stops sound travelling out through the back of the framing, and it adds £150. Put that next to the RGB smart lighting upgrade at £150–£300, which is much the same outlay. One changes how the wall feels every evening. The other changes what shade it glows. In flats the framework gets Rockwool RWA45 as standard for £200, which cuts the TV bass reaching your neighbours by 60 to 70 per cent, and we run mass-loaded vinyl behind the plasterboard on the party-wall side. Basement installs get both, because in a basement the sound carries up into the room above.
What reads as expensive in 2026
The look most guides tell you to add is the look that now dates a room. Gloss black panelling with a colour-changing strip behind the screen was the show-home formula of the late 2010s, and it reads as a copy of a showroom rather than something designed for your room. What reads as expensive now is letting the material do the work: vertical 30mm oak slats at 8mm shadow gaps in a matte clear oil, one surface carried across the full width, warm-white 3000K on a dimmer instead of sixteen million shades, original cornicing running uninterrupted above it. The slatted panel doing most of that work adds £400–£800 over painted plaster, against £1,200–£2,000 for doored cabinetry that changes the wall far less.
Our own order book agrees. Warm-white 3000K dimmable LED is the standard specification on every build and colour is a paid upgrade, not the default. The most-chosen style in Clapham, Dulwich, Crystal Palace and Balham is slatted oak with painted alcove cabinetry — Down Pipe in Clapham, Hague Blue in Crystal Palace and Balham — with brass cup handles and nothing that flashes. Where clients do take the smart RGB upgrade it tends to be the wide Bromley wall-to-wall builds rather than the period front rooms.
From our London projects
Across 128 installs since 2022 — 41 in Clapham, 28 in Dulwich, 23 around Crystal Palace, 19 in Bromley, 17 in Balham — the walls clients photograph most are the quiet ones. A Clapham Common North Side terrace of 1885 took slatted honey oak, a Solution Fires SLE140, a 65-inch recess, Down Pipe alcove cabinetry with brass cup handles, and the original cornicing kept and painted to match: £5,200 over ten working days. A Crystal Palace Triangle Victorian of the same year ran the same recipe in Hague Blue with the ceiling rose restored, £4,900 over nine days. Neither has a colour-changing strip anywhere in it.
Tight rooms are where geometry earns its money. Clapham front sitting rooms are 3.2 to 3.8m wide, and a design that misses the chimney breast by 5mm is a design you can see from the sofa, which is why Richard Thomas-Pryce surveys every job himself before a price is written. Where a room fails the numbers we say so at the survey rather than at handover. A Nightingale Lane loft conversion in Balham, angled ceilings and no room for a deep recess, took a 55-inch screen in a matte black painted MDF surround with a slim wall-effect fire and no heat, £4,200 over seven days, and it looks better than the bigger wall somebody could have sold them.
