Smart home, control and AV systems for prime London properties
A smart home that genuinely works is not a collection of gadgets – it is a building system, engineered with the same discipline as power, heating or drainage. Behind every calm, reliable interface sits infrastructure: structured cabling, a properly designed network, an equipment room with power and ventilation, and a control architecture that was decided before the first cable was pulled. When those foundations are right, technology recedes into the background of the home. When they are missing, no product catalogue can compensate.
AVC designs the architecture first and selects the platform second. We define what is controlled, from where and by whom; we design the cabling, network and equipment space that any credible platform will need; and only then do we recommend Crestron Home, Control4, Lutron or a combination – on the merits of the project rather than a house allegiance. Because we also deliver the electrical installation on most of our projects, the technology scope arrives coordinated with its power, containment and lighting circuits from the outset.

A smart home brings a property’s lighting, shading, climate, audio, video and security interfaces together under one engineered control system, so the building is operated through considered keypads and interfaces rather than a drawer full of separate apps. AVC Integrations designs, installs, programs and supports these systems for prime residential projects across London – defining the system architecture first, selecting the control platform second, and remaining accountable from design through commissioning to long-term ownership.
The starting point
The problem: products specified where a system was needed
Most disappointing smart homes were bought as a shopping list. Devices were chosen room by room, each with its own app and its own assumptions, and the connective tissue – cabling, network, equipment space, a single control architecture – was never designed at all. The symptoms are familiar: walls crowded with mismatched panels, an amplifier warming a joinery cupboard that was never ventilated, a Wi-Fi network asked to carry systems it was never engineered for, and a household that has quietly stopped using half of what it paid for.
The deeper failures surface later. Nobody holds documentation, so no other integrator can take the system on. The programming lives with one individual who has moved on. The cabling that would have cost little at first fix now requires decoration to be undone. At that point the conversation is no longer about features – it is about what replatforming will cost, and which walls have to be opened to do it. Every one of these outcomes was avoidable on drawings.
How AVC works
The AVC approach: architecture first, platform second
We begin with how the household actually lives, not with a brand. From that brief we design the system architecture: which systems are controlled and which are merely interfaced, where keypads and touch panels sit, what the structured cabling must reach, how large the equipment room needs to be, and what the network must carry. Only once that architecture exists do we select the platform. Crestron Home and Control4 are both capable whole-home control platforms with different characters; Lutron HomeWorks is the flagship platform for lighting and shading and frequently runs alongside either. We have published detailed comparisons and we advise project by project – the platform serves the architecture, never the reverse.
Integration scope is defined honestly and early. We do not claim that every third-party product can be brought under one roof – we agree, in writing, which systems are integrated, which are interfaced at a defined level, and which remain standalone. Because AVC typically delivers the electrical package as well, containment, power supplies, lighting circuits and control cabling are coordinated by one team in one model, and the technology scope is programmed, commissioned and documented by the people who designed it.

Systems and integration
- Lighting and shading control, including Lutron HomeWorks where specified
- Climate interfaces coordinated with the mechanical design and its zoning
- Multiroom audio with concealed and architectural loudspeakers
- Home cinema and media rooms engineered as part of the whole-home system
- Video distribution to displays and projection
- Door entry, CCTV and security interfaces – integration scope defined per project
Delivery and ownership
- Installation by our own teams, coordinated with the electrical package
- Rack building with dressed, labelled and tested cabling
- Programming, configuration and scene-setting with the client
- Commissioning and room-by-room demonstration
- As-built documentation, cable schedules and configuration records
- Support and maintenance arrangements for long-term ownership
Interfaces, resolved
Resolved with the design team, not imposed on it
An integrated home touches almost every trade and every finish, which is why the technology conversation belongs at the design table rather than on site. Keypad positions sit within wiring-accessory schedules; speakers penetrate decorated ceilings; screens live inside joinery; the equipment room competes for plant space with everyone else. We resolve these interfaces on drawings, while moving them is still free.
- Keypad and touch-panel positions agreed with the interior designer as part of the accessory schedules
- Speaker, screen and projector locations coordinated with joinery, lighting and ceiling design
- Equipment rooms sized, powered and ventilated before spatial decisions close
- Structured cabling routes resolved alongside the wider electrical containment design
- Climate control zoning agreed with the mechanical engineering, not bolted on after it
- Network and Wi-Fi provision engineered as infrastructure, with the coverage the systems demand
- Access for service and future replacement preserved behind every finish

Timing
Why the system must be designed before first fix
Almost everything that determines whether an integrated home succeeds is buried in the walls at first fix: cable routes, back-box positions, speaker provisions, equipment-room allowances, network points. These cost comparatively little to include on drawings and a great deal to add once plaster and decoration are complete. The platform can be debated late; the infrastructure cannot. A project that reaches first fix without a technology design has already made its most expensive decisions – by default.
AVC prefers to join at concept or developed design, alongside the architect and interior designer, so the architecture is designed into the building rather than negotiated with it. We do join projects that are further along – but the earlier conversation consistently produces the calmer home and the smaller final account.

Frequently asked questions
Which platform is best – Crestron Home, Control4 or Lutron?+
There is no universal answer, which is why we design the architecture before naming a platform. Crestron Home and Control4 are both whole-home control platforms with different strengths in interface design, scale and programming depth; Lutron HomeWorks is the flagship lighting and shading platform and often runs alongside either. We have published detailed comparisons, and on each project we recommend the combination the brief and budget actually support.
Does everything in the house end up on one system?+
Not necessarily, and we are deliberate about saying so. On every project we define which systems are fully integrated, which are interfaced at an agreed level – security is a common example – and which remain standalone. That scope is recorded in writing before programming begins, so expectations and reality match at handover.
Can a smart home be retrofitted into an existing property?+
Yes, with honesty about the constraints. Wireless devices help, but a dependable system still wants a cabled backbone, an equipment location and a properly engineered network, so the natural moment is a refurbishment when floors and walls are already open. On lighter-touch retrofits we design around the access that exists and are clear about what each compromise means.
What has to be decided before first fix?+
Everything that lives inside the fabric of the building: cable routes and containment, keypad and socket positions, speaker and screen provisions, the equipment room and its power, and the network points. The choice of platform can move later; the infrastructure realistically cannot. This is why we push the technology design ahead of the electrical first fix rather than behind it.
Who programs the system – and who supports it afterwards?+
AVC's own engineers program, configure and commission the systems we design, and the configuration records stay with the project rather than in one individual's head. At handover we agree a support arrangement, so software updates, adjustments and additions have a clear route. A home should never depend on finding the one person who remembers how it was set up.
What happens if the internet goes down?+
Day-to-day control – lighting, shading, climate, audio – runs on the home's own local network, not on someone else's cloud, so an internet outage should cost you remote access and streaming rather than your light switches. That resilience is a design outcome, not a default: it is one of the reasons we engineer the network as seriously as any other building service.
What documentation do we receive at handover?+
As-built drawings, cable schedules, rack layouts, network records and the system configuration, together with a plain-English guide to daily use. The test we apply is simple: a competent integrator who has never seen the property should be able to take the system on from the documentation alone. That is what protects the owner's investment over the long term.
Will the system be obsolete in a few years?+
The electronics will evolve; the infrastructure should not have to. We design the cabling, containment and equipment space so devices can be replaced or upgraded without opening walls, and we specify established platforms with long support histories rather than fashionable hardware. Obsolescence is managed at the architecture stage – it is much harder to manage anywhere else.
