Home Automation for Large Homes

Why Home Automation Systems Excel in Large Properties

A well-designed, properly installed home automation system is a genuinely convenient way to manage the electrical systems in a home — and the benefits scale directly with the size of the property. Touchpanels and iPads provide simplified control across every subsystem, with whole-house overview pages letting clients see at a glance which devices are in use and where. In a property with many bedrooms — more than are in regular use at any one time — lowering the heating setpoint in unused rooms until they’re needed saves considerable energy. Whole-home lighting control lets clients see exactly where lights are on and switch every light in the property off with a single button press on the way out.

Here are the major elements we typically address in a large-home project:

Audio Video Distribution

In a house with multiple televisions, the usual choice is either accepting that satellite recordings are only available in certain rooms, or spending a fortune cluttering every room with its own expensive satellite receiver. We centralise sources instead, so a household’s favourite recordings are available anywhere in the home. Activating a personal profile on any touchpanel — including an iPad — brings up that person’s recordings in whichever room they’re in, alongside their preferred radio stations and playlists. Standardising AV control throughout the property means the experience is identical regardless of which room someone happens to be in.

Lighting Control

This is the simplest way to save energy in a large home while also making sure it looks its best. Mood lighting gives every room independent scenes, and because every circuit sits within one wider system, it’s straightforward to see at a glance where lights are on and switch them off centrally. A dimmed lamp also uses a fraction of the energy of a fully switched-on light — savings that genuinely add up when a property has hundreds of fittings.

Heating & Cooling

Setting temperatures on a per-room basis allows infrequently used rooms to run cooler than the rest of the property. Air conditioning can switch off automatically when a room is vacated, or cycle once its setpoint is reached. Because heating and cooling sit under one control system, they never compete with each other — underfloor heating never tries to warm a room that air conditioning is simultaneously cooling, or vice versa. Integrating both with lighting and blind controls lets us manage sunlight levels directly, reducing heat gain without relying on air conditioning at all — in some properties, we can even open motorised roof lights to cool a space naturally. Every system we design has its own energy-efficiency logic built in from the outset, and as clients move between rooms and log into their personal profile, their preferred heating and air conditioning settings follow them automatically.

Renewable Energy Integration

Integrating renewable energy sources makes particular sense within a home automation system, since it enables devices to run precisely when energy production is at its highest. Our systems can schedule tumble driers or bathroom towel rails to operate when solar production peaks, or divert hot water to swimming pool heating once underfloor heating demand has been satisfied. Detailed reporting lets clients see exactly where energy is being used around the property, with both live statistics and historical data available.

Intercoms and Gate Access

A fully integrated gate access system lets clients open gates from a mobile phone, with straightforward management for staff and regular visitors — all that’s needed is a phone number, and the system recognises an approved visitor automatically, including restricting access to specific days if required. Visitors at the gate ring touchpanels throughout the home — the same panels that control AV, lighting and heating — allowing two-way communication before the gate is opened or the call ends. The same touchpanels handle intercom between individual rooms or to the whole property, useful for announcing an arriving car or that dinner is ready. Because the system is profile-driven, a specific person can even be paged directly, with only the panel in the room they’re actually in ringing.

Remote Control

No one wants to arrive home to a dark, cold property after time away. Our systems allow full control from a client’s smartphone or tablet from anywhere, with alerts notifying them of issues before they become a larger problem.

We typically specify Crestron home automation systems for projects at this scale, giving us the complete flexibility to integrate every element described above within a single, coherent system.

Case Study: A Genuinely Comprehensive Large Home, Derby

This new-build in the Derby countryside is one of the clearest demonstrations we have of everything covered above working together in a single large property. Twenty-four audio zones and sixteen video zones run alongside full security, CCTV and gate intercom, all managed from the same touchpanels as the lighting and HVAC systems — no separate controller for any of it, anywhere in the property. The heating and air conditioning integration alone covers underfloor heating, air conditioning and heat recovery units in every room, exactly the kind of per-room, non-competing climate control that only becomes possible once a large property’s systems are unified rather than left to run independently.

The lighting side of the project won Custom Controls a Crestron Integration Award in its own right — over 350 Crestron LED fittings across 200-plus channels, installed as the first project of its kind in the UK, brought the whole house’s lighting energy use down to roughly what the kitchen and dining room alone previously consumed. It’s a genuinely useful illustration of how much energy and complexity a large home can quietly absorb once every system answers to one properly designed control layer. Read the full case study →

Frequently Asked Questions — Home Automation for Large Homes

Why does home automation matter more in a large home than a small one?
The savings and convenience scale directly with property size — a large home with many infrequently used rooms, dozens of lighting circuits and multiple AV zones has far more to gain from centralised control than a smaller property with fewer systems to coordinate.

Can heating and air conditioning be managed by the same system without conflicting?
Yes. With both under one control system, underfloor heating and air conditioning never compete — one system never tries to warm a room the other is simultaneously cooling.

Can gate access be managed without issuing physical keys or fobs?
Yes. A properly integrated system can recognise pre-approved visitors by phone number alone, automatically granting access, with the option to restrict access to specific days where needed.
