I’m ready to turn a 4.3 m × 6.6 m spare room into a true home cinema and need a complete interior design package in a modern style. The space should comfortably house 5–7 individual recliners, laid out so every viewer has an unobstructed sightline and an immersive audio experience. Here’s what I’m after: • Floor plan and seating layout that balances aisle width, screen distance and speaker placement. • Mood-board showing the modern aesthetic—think clean lines, muted palettes, subtle LED accents and acoustically transparent wall panels. • Detailed drawings or 3-D renders for walls, ceiling, flooring and built-ins, including recommended finishes, fabrics and lighting fixtures. • Acoustic treatment plan (bass traps, diffusers, absorbers) plus wiring routes for surround sound and hidden cabling. • Final material & equipment schedule so I can hand everything straight to the contractor. I’ll review the design against seat capacity, viewing angles and a cohesive modern look before sign-off.
