Whether you have a vacant space under your house or a second living area you want to put to better use, a home theatre allows you to enjoy movies at home in ultimate comfort. There’s a lot more to creating the perfect home theatre setup than just buying the biggest screen you can afford. From deciding on the best layout to selecting the right AV, we’re running through all the must-haves so you can create the perfect media room in your home.

Planning the layout
The cornerstone of any successful media room is careful space planning that weighs up best viewing experiences with functional living requirements. Your room size directly influences your equipment options and seating configurations. Naturally, larger rooms support multiple rows of seating and more elaborate sound designs, while smaller rooms are better suited to snug layouts.
This is where advice from spacial planning experts is worth its weight in gold. They provide these measurements for optimal viewing and room flow:
- measure the diagonal distance of your screen and multiply this by 1.5-2.5 to get the optimal distance from the screen for the first row of seats (this can be cut back by a little for 4K screens due to the greater pixel density)
- allow a clearance of 700-900cm between seat rows and walkways for comfortable movement. When you consider that recliner seats are most commonly used in theatre rooms, this means the seats will be approximately 1.5-2m apart
- if you are building tiered flooring, there should be at least 15-30cm between levels for clear sightline.
Tip: don’t place seats hard against the wall. Doing so will make the room feel visually heavy and provide a poor sound performance as sound reflects against walls.
Acoustic design
One design element you cannot overlook in a home theatre is acoustics. More than just finding the best speakers you can afford and positioning them across the room, you also need to think about all the materials in the space and how they’ll affect sound clarity. For example, soft furnishings like carpets and drapes absorb reverberations and produce crisper soundstages.
To transform a regular room into the ultimate home theatre, you may want to install acoustic panels on the ceiling and/or walls. There are so many designs and materials on the market, you’ll be able to find one to perfectly complement your design vision. Alternatively lining the walls with thick drapes will also provide acoustic benefits and creates the classic home theatre aesthetic. For media rooms built on concrete slabs, using high-quality concrete sealers not only protects the flooring but also reduces dust and moisture issues that can impact both equipment longevity and overall room comfort. Place speakers at the same level as ears for seated audiences, so surround sound speakers are not obstructed by furniture or building characteristics.

Lighting control
Another critical design element is lighting. To create the perfect at-home movie experience, dimmable lights are a must but you can get more creative. A drop ceiling with LED strip lighting or slim LED strip lighting integrated into walls can completely elevate the look of the space. Consider the different layers of lighting and how you can apply these — task, ambient and accent lighting. We have more information about how to create a lighting plan here.
It’s also important to consider how you’ll manage natural light. If there are windows in the room, blockout curtains will eliminate sunlight and prevent screen glare.
Wiring and cable management
Good electrical and data infrastructure is the unobtrusive base that makes all your well-chosen equipment work efficiently. Strategically place electrical outlets across the room, not only for current equipment requirements but for future additions and holiday decorations as well. Australian electrical regulations call for professional electricians to lay new circuits, so schedule this work as part of any wider renovation effort to reduce disruption and expense.
Organised cabling avoids the ugly cable jungle that can turn a high-tech media room into a technical nightmare zone. Route cables through walls and ceiling cavities wherever practical, exiting at designated equipment points and seating locations. Provide for HDMI, ethernet, speaker wire, and power cords, some extra capacity for future needs you can’t yet envision.
Cable management is especially important when you are linking several devices to multiple displays and speakers. Contemporary media rooms usually feature gaming consoles, streaming devices, PCs, and specialty gear that all must be able to connect easily with your main display systems. When you’re linking several devices such as a gaming console, streaming box, and PC, KVM switches allow you to easily switch sources without endless plugging and unplugging.
Plan out the routing routes for all cables in the planning stage since back-terminating cable runs within completed walls and ceilings can be costly and time-consuming. Provide separate circuits for high-wattage devices such as projectors and amplifiers, and provide proper ventilation for equipment that produces heat when run continuously.

Selecting the proper AV equipment
Display choice is one of the most important decisions in your media room project, with projectors and large flat panel TVs each having pros and cons. Projectors perform best in larger rooms where you want genuine cinematic screen sizes, but they need to be used with controlled lighting and frequent servicing. Large format TVs have brighter images that perform better in multipurpose rooms and need less ongoing maintenance.
Audio systems can vary from basic soundbar solutions to sophisticated surround sound setups with in-wall speakers and specialised amplification. Take into consideration your acoustic properties of the room, neighbour proximity, and family viewing habits while choosing the audio hardware. In-wall and in-ceiling speakers offer uncluttered aesthetics but mean planning during construction stages, and conventional speaker setups have more flexibility to make future adjustments and upgrades. Keep in mind that technology advances quickly and built-in options are less flexible and difficult to upgrade.
Once you have the screen and speakers sorted, you may want to consider other accessories. For example, devices to support streaming media, game systems, and smart home integration. You’ll also need to plan where you’ll store these and design good ventilation. For example, a wall-hung entertainment unit with mesh base could be an ideal solution.
As if all that wasn’t enough to think about, you should also keep ‘future-proofing’ at the forefront of all your decisions. Technology is advancing at lighting speed and to create a media room that functions well now and into the future, you need to be able to upgrade equipment as required. HDMI ports with sufficient bandwidth, network hardware with high-resolution streaming capacity, and modular system architecture enable component upgrades without system overhaul.
Smart features and controls
Seamless integration with wider smart home systems turns your media room from a standalone entertainment area into a fully integrated component of your smart automated home environment. Smart lighting systems automatically dim when a movie starts, and motorised blinds adjust according to ambient light sensors or timed programming. Integration with climate control ensures relaxed temperatures for long viewing sessions while keeping energy consumption under control.
Universal control systems eliminate the frustration of juggling multiple remote controls while providing intuitive interfaces that all family members can operate confidently. Modern systems integrate voice assistants, smartphone apps, and traditional remote controls to accommodate different user preferences and technical comfort levels. Program common scenarios like ‘movie night’ or ‘gaming session’ to automatically configure lighting, audio levels, and input selections.
Centralised control centres coordinate various smart devices and offer standby control mechanisms when primary systems are experiencing problems. Think about systems that function smoothly without internet access for basic functions to keep your media room up and running during network failures or service interruptions.
Network infrastructure is more vital as more connected devices and streaming services are integrated into media rooms. Provide sufficient bandwidth and dependable wireless coverage across your media space, while wired connections for fixed devices that take advantage of continuous, high-speed data connections.
