Media Wall Mistakes to Avoid: Planning, Layout & Cost Errors

Mistake 1: Building too tightly around the TV

One of the most common mistakes is designing a media wall exactly to the size of your current TV. Screens rarely get smaller, and tight openings quickly become a limitation.

• Leave clearance for future screen upgrades
• Avoid boxing the TV in too tightly
• Plan a layout that still looks balanced if the screen grows

“Designing for the TV you’ll own in five years avoids expensive rework later.”

Mistake 2: Underestimating storage needs

Media walls that focus purely on appearance often lack enough practical storage. Devices, remotes, games and paperwork quickly create clutter if they don’t have a home.

• List everything you’ll store before designing
• Balance open shelving with closed cabinetry
• Plan storage for items you use daily

Mistake 3: Poor cable and socket planning

Visible cables are one of the fastest ways to undermine an otherwise great media wall. Cable routes and socket positions should be planned before finalising the layout.

• Decide where each device will live
• Ensure access to power and ports
• Allow flexibility for future changes

Mistake 4: Forgetting ventilation for devices

Consoles, routers and AV equipment generate heat. Without ventilation, performance and lifespan can suffer.

• Allow airflow for enclosed devices
• Avoid sealing electronics into tight spaces
• Plan ventilation early rather than retrofitting

Mistake 5: Focusing on finishes too early

Finishes are important - but prioritising them before layout and storage often leads to regret. A strong foundation allows finishes to evolve over time.

Mistake 6: Ignoring business or multi-use requirements

In boardrooms and showrooms, media walls often fail when they don’t account for professional use: device access, reliability and presentation quality.

• Hidden but accessible equipment storage
• Clean, professional finishes
• Easy upgrades for screens and devices
