Home Cinema Design: Projectors, Sound and Smart Home Integration

Today I want to talk about home cinemas. Anyone who has followed my work for a while has probably noticed that I am a big fan of modern technology. I enjoy good sound, I love films, and I like being able to control my home without unnecessary effort.

I believe these things should be discussed as part of the interior design. When we design a house or an apartment, I want to understand how someone will actually live there: where they will watch films, listen to music, play games, work and relax. The same applies to terraces and other outdoor spaces.

So I am going to start this conversation about home cinemas a little further back, with everyday convenience. Because a large screen on its own does not solve everything.

Smart home technology: what I actually find useful

It seems strange to me when a modern home still requires you to keep track of things that a system could monitor. Checking the salt level in a water softener, remembering when a filter was last replaced, walking from room to room to turn off the lights or close the curtains.

Our phones are almost always nearby anyway. I find it convenient to open an app and see what is happening at home. But it is even better when I do not need to check anything without a reason: the system tells me when something needs attention.

For me, this includes things as small as a pet’s water fountain. I would rather receive a reminder to replace its filter than keep another date in my head.

Of course, notifications need to be configured, and monitoring equipment requires compatible devices or sensors. An app will not automatically know about everything happening in the house.

Remote control is another useful part of this. On the way home, you can adjust the temperature in advance, check on your pets through a camera or see whether a parcel has arrived. That requires equipment with the right capabilities and properly configured, secure remote access.

At the same time, I certainly do not think we should get rid of ordinary switches and manual controls. Considering how unpredictable life can be, I would keep a way to use essential things without a phone. That includes being able to open curtains manually, provided the chosen system allows it.

It is also important to distinguish between losing the internet connection and losing electricity. Basic smart home functions can run locally without constantly contacting a cloud service, but the equipment still needs power.

I like automation that removes unnecessary routine. Having to find an app every time I want to turn on a light is exactly the kind of thing I do not like.

Good Wi-Fi needs to be planned with the interior

All of this brings me to the next subject: the home network.

In hotels, I have often noticed how much Wi-Fi quality can vary between rooms. The internet works normally in one area, while a room further away has a very weak signal. It is particularly frustrating when the space itself is good, but you cannot comfortably work or watch a film.

I would certainly not want to repeat that situation at home. In a large apartment, a house with several floors or a layout with many internal walls, network equipment needs to be considered alongside the floor plan.

I like a setup with a main router and separate wireless access points. Network cables are installed in advance, and the access points are positioned where a connection is actually needed: living spaces, a home office or the terrace. In this configuration, the main router does not have to broadcast Wi-Fi at all. The access points handle that.

With a properly configured network, your phone can move between access points as you walk around. This is often described as seamless roaming, although the result depends on both the network and the device: the phone or laptop decides when to move to another access point.

I would consider two access points even in a smaller apartment with an awkward layout or walls that significantly weaken the signal. But installing two simply because someone says that is the minimum would not make sense either. Their number and position should be determined by the actual space.

For me, this belongs in the project just as much as the position of electrical sockets. I would rather know where the network equipment will go and where the cables will run than finish the interior and start looking for somewhere to put a router and hide a cable along a completed wall.

A dedicated cinema room or a home cinema in the living room?

When a house has an available room, I would seriously consider turning it into a dedicated cinema.

We have designed several interiors like this over the years. And I think that for someone who enjoys films, series or games, it is one of the most enjoyable things they can have at home.

You come home in the evening, sit in a comfortable chair or on a sofa, and turn on a large screen with good surround sound. You can simply watch a film without being distracted by everything happening around you. Personally, that is a way of spending time I really enjoy.

But I do not associate a home cinema exclusively with an enormous house. I would consider a smaller room for this purpose too. The starting point should be how many people will watch, where they will sit and how large an image they actually need.

Without a separate room, a home cinema can be planned as part of the living room. I like the idea of the room remaining a normal living space, with the screen appearing only when it is needed.

I would not chase the largest possible screen at any cost, though. First, I would want to know whether it is comfortable to watch from the chosen seat. What matters is wanting to spend two hours there watching a film, rather than showing guests the screen size once.

Projector or TV: why I prefer a projector

For watching films, I personally prefer a projector.

That does not mean I think all televisions are bad. OLED, Mini LED and other display technologies have their supporters, and I understand why someone might choose a TV. For fast competitive games, I would also be more inclined to look at a good gaming monitor than choose a device purely for the size of its picture.

But for cinema, I like the way a good projected image feels. To me, it has a softer, calmer, more cinematic quality. Sometimes I want to describe that feeling as slightly film-like, although I am obviously not talking about actual film or a lack of sharpness. It is simply a more enjoyable way for me to watch a movie.

Your previous experience matters here too. I would not judge every projector after seeing a random budget model costing, say, €200. I would first watch a good projector in a properly prepared room, then decide whether I liked the experience.

I also find the gaming capabilities of projectors interesting to follow. Some models already offer 120 Hz and 240 Hz modes, but the available refresh rate depends on the resolution. Both resolution and input lag need to be checked.

I think projectors will become even more interesting for gaming over the next few years. But I would not promise that they will replace TVs and monitors in every respect. What matters more to me is that there are already different options for different ways of using a space. One person wants a screen for a short gaming session after work; another wants a dedicated room for a much more immersive experience.

And these do not have to be mutually exclusive choices. A home can have a television for everyday viewing and a projector for films.

The screen and sound matter as much as the projector

A television is usually a more straightforward purchase. You buy a device that already includes a screen and built-in speakers. For everyday viewing, that may be enough.

With a projector-based home cinema, I would consider the complete setup from the beginning: the projector, a projection screen and a separate sound system. Some projectors have built-in speakers too, but a full surround-sound experience requires a separately chosen audio system.

I would not leave the projection surface as an afterthought either. The screen, its size and position, and the ability to darken the room should be discussed while choosing the equipment. I do not like the approach of buying a projector first and only then trying to work out where to put it and what to project onto.

Sound is an even bigger consideration for me. A good image without suitable audio does not give me the experience that makes me want a home cinema in the first place.

And I am not simply looking for volume. I want to hear dialogue clearly, feel the space within a scene and understand where a sound is coming from. Speaker positions relative to the audience matter, so the speakers should be arranged around the chosen seating positions, not simply placed in whichever corners happen to be available.

For an apartment, I would also discuss sound isolation separately with a specialist. I want watching a film to be enjoyable for the person using the cinema without creating a problem for people in neighboring rooms or apartments.

When discussing the budget, I would compare complete systems rather than the price of a TV with the price of a projector alone. It needs to be clear what each option includes: screen, sound, mounts, cables, installation and setup. Without that, a conversation about which one costs more is not particularly useful.

Why home cinema design should start before the finishes are complete

I believe this is a job for specialists.

That does not necessarily mean finding some inaccessible company on the other side of the world. A good local specialist can be the right place to start.

But I would not stop at advice from the first sales assistant I happened to meet in a store. I would want someone to look at the room, ask how I intend to use the system and help choose everything together. Then install and configure it.

As an architect, I want to understand in advance where the screen will be, where people will sit, where the cables will run, how the speakers will be positioned and how everything will be controlled. These questions should be agreed before the finishing work is complete.

For example, I like the idea of deciding to watch a film, selecting one mode and having the room prepare itself. The curtains close, the lights dim and the relevant equipment turns on. Afterwards, returning the room to its normal state should be just as straightforward.

At the same time, I do not want to live in a room where the equipment demands more attention than the film.

That is probably the main point. I love modern technology, and I want to see it in our projects. But ultimately, what matters to me is that someone can come home, sit comfortably, put on a film and enjoy it. Without having to work out how everything operates every evening.
