Home WiFi & Network Installation | Large Property Specialists

Designers & Installers of the Best Home Wifi & Networks Available

Fast, reliable connectivity in every room, on every terrace, throughout the grounds — engineered for your property, not estimated from a brochure. A large private home is one of the most demanding networking environments that exists. Thick stone walls, multi-storey layouts, basement cinema rooms, detached garages, pool houses, outbuildings, and extensive garden spaces all conspire against the consumer products designed for a two-bedroom flat. The result is familiar: dead zones where there should be signal, dropped connections during video calls, smart home devices that lose contact with their controller, streaming that buffers in rooms that cost more to build than most people’s homes.
Custom Controls designs and installs professional home networking for private residences where these things are not acceptable. The systems we specify are the same class of technology used in high-performance commercial environments — large hotels, financial institutions, healthcare facilities — where connectivity cannot be left to chance. Surveyed, engineered, and installed by our own team, they deliver the performance and reliability that a demanding household requires, invisibly and permanently.
We have designed networks for six-storey London townhouses, large country estates spanning multiple buildings, Alpine ski chalets with thick timber construction, and Dubai villas with extensive grounds. Each one presented different challenges. Each one was solved the same way: with a proper survey, a proper design, and the right equipment installed correctly.

The Problem with Standard WiFi – What Your Current System Cannot Do

Consumer WiFi products — including the latest mesh systems heavily marketed for large homes — are not designed for the specific demands of complex residential properties. They are designed to sell well in supermarkets. They are not designed for your home. Dead zones are the most visible symptom. Thick walls, substantial floor structures, and the sheer distances involved in a large property defeat consumer access points regardless of how many you add. A system that delivers excellent performance in the kitchen may be completely unusable in the basement cinema room, the pool house, or at the far end of the garden. Device overload is less visible but equally disruptive. The average large private home now has well over fifty connected devices — smart home controllers, IP cameras, multi-room audio systems, streaming devices, tablets, phones, kitchen appliances, heating and climate systems, and building management infrastructure. Consumer systems are not engineered to manage airspace efficiently across this range of device types and usage patterns. Performance degrades. Devices drop offline. The smart home system that was supposed to make your life easier becomes a source of daily frustration.
Consumer mesh systems suffer from a fundamental architectural weakness: wireless backhaul. The nodes talk to each other over the same wireless spectrum they use to serve your devices. Every hop between nodes reduces available bandwidth. A network that shows impressive speeds on a speed test near the router delivers a fraction of that performance at the far end of a large property — because the signal has been degraded by multiple wireless hops before it reaches your device. Our installations use wired Ethernet backhaul throughout. Every access point is connected to the network by cable. Full speed is delivered at every point in the property, regardless of how many access points there are, how far apart they are, or how complex the building is. This is not a luxury — it is the correct way to build a network for a property of this type.

Our Approach – Surveyed. Engineered. Installed. Supported.

No two properties present the same networking challenge, and we do not apply a standard template to any project. Every network we design begins with a detailed survey.
Site Survey
We assess the property thoroughly before specifying anything. Building construction and materials — stone, concrete, timber, steelwork — all affect signal propagation differently. We map the layout, identify the locations of all access points, plan cable routes, and establish exactly what the network needs to deliver. For properties where we are involved from the planning stage, we advise on conduit positions and cable routes during construction — ensuring the infrastructure is in place before walls are plastered and floors are laid.
System Design
From the survey, we produce a complete network design: access point positions, cable routes, switching architecture, VLAN structure, and management platform. For complex properties, this includes multiple network segments — personal devices, smart home infrastructure, IP cameras, guest access — each properly isolated from the others. The design is reviewed with you before any work begins.
Equipment Selection
We specify access points from Cisco Meraki, Ruckus, Pakedge, and Ubiquiti — enterprise-grade manufacturers whose products are engineered for demanding environments. These platforms manage the wireless environment with a sophistication that consumer hardware cannot match: intelligent band steering, seamless client roaming between access points, detailed traffic management, and the capacity to handle large numbers of simultaneously connected devices without degradation. For retrofit projects where running cable is impractical in certain areas, we design hybrid solutions — wired Ethernet to key locations, with wireless backhaul used strategically where cable access is not possible. The wireless backhaul hops are minimised and managed — the result is dramatically better than a pure mesh system.
Installation
All cabling is installed by our own engineers. Access points are positioned precisely according to the design — not wherever is convenient. Equipment is housed in proper networking enclosures, not cable-tied to the back of a shelf. The installation is clean, professional, and leaves no visible trace beyond the access points themselves, which are flush-mounted and paintable where required.

Security Built In – Your Network, Properly Protected

A large private home with extensive smart home infrastructure, IP cameras, and sensitive personal devices connected to the same network presents a meaningful security risk — one that most consumer network installations completely ignore. We design every network with proper segmentation from the outset. Your personal devices — phones, laptops, tablets — operate on a private, secured network with full access to your smart home systems. Guest devices connect to a separate network with appropriate bandwidth allocation but complete isolation from your private systems and devices. Smart home controllers, lighting systems, and climate control operate on their own dedicated network segment. IP cameras and security infrastructure operate on another. Building management systems on another still. This architecture means that a compromised guest device — a visitor’s phone with malware, for example — cannot see or access any of your personal data, your smart home systems, or your security infrastructure. It is not overcautious for a property of this value. It is the correct way to design a network.
Parental controls, content filtering, and scheduled network access are available for households with children — applied per device, per network segment, or per schedule, managed centrally without any technical knowledge required from the family.

Understanding Your Options – The Honest Guide to WiFi Architecture

Wired WiFi (our preferred approach for most projects)
Access points connected to the network by Ethernet cable. The backbone runs at full gigabit — or multi-gigabit on modern networks. Every access point delivers full performance regardless of its position in the building. Seamless roaming is managed by a central wireless controller, which hands your device from access point to access point as you move through the property without any interruption to streaming, calls, or smart home operation. This is the gold standard for large properties. For new builds and major renovations, it is the only approach we recommend.
Mesh WiFi (appropriate for specific circumstances)
Access points that communicate with each other wirelessly rather than over cable. Easier to retrofit into existing buildings where cabling is genuinely impractical. Performance is inherently limited by the wireless backhaul — bandwidth is shared between serving client devices and maintaining the inter-node links. Modern tri-band mesh systems have reduced this limitation significantly, and for properties where cabling is not possible, well-designed mesh delivers genuinely impressive results. The key word is well-designed: node placement, channel selection, and controller configuration matter enormously.
Hybrid (our most common retrofit solution)
Wired Ethernet to the key locations that can be cabled, with mesh technology extending coverage to areas where cable access is not practical. This approach delivers the majority of the performance benefits of a fully wired system, while accommodating the constraints of an existing building. A mesh node talking to a wired access point one hop away delivers dramatically better performance than a mesh node at the end of a long wireless chain.
Multiple WAN and Connectivity Resilience
For properties with demanding connectivity requirements or unreliable primary broadband — including rural properties, remote country estates, and international homes — we design multi-WAN architectures that combine broadband, leased line, 4G/5G, and satellite connections. Traffic is load-balanced across available connections under normal conditions. If any connection fails, the others take over automatically and immediately — no interruption, no rebooting the router, no calling the ISP. For properties where connectivity is genuinely critical, this is not an optional extra.

The Foundation of Everything – Every System in Your Home Depends on This.

The network is not separate from your smart home installation. It is the infrastructure on which every other system depends. Crestron automation controllers, Lutron lighting systems, multi-room audio distribution, IP cameras, cinema room control systems, gate and access control, climate systems, and every streaming service in the property all rely on the network performing reliably and consistently. A poorly designed network is the single most common cause of smart home unreliability — and one of the most frequently overlooked elements in the initial specification when technology is being installed by companies that treat networking as an afterthought.
When Custom Controls is responsible for both the smart home system and the network infrastructure, they are designed together from the outset. We know what bandwidth the cinema room distribution system requires. We know what latency the Crestron controllers need. We know how many concurrent streams the multi-room audio system will generate. The network is sized, segmented, and engineered for the actual demands of your specific installation — not for a generic set of assumptions about what a home network might need to do.

Supported for Life

Every network we install is remotely monitored by our team. We receive alerts when an access point goes offline, when a switch port fails, when unusual traffic patterns emerge, or when any element of the network degrades. In most cases we identify and resolve issues before the client is aware of them. Software updates, configuration changes, the addition of new devices, and the expansion of the network to new areas of the property can all be managed remotely without the need for a site visit. When on-site work is required, we schedule it at a time that minimises disruption. We have maintained networks installed over a decade ago. As the property’s technology has evolved — new smart home systems, new cinema rooms, new outbuildings — the network has been expanded and upgraded to accommodate it. This long-term relationship, and the remote visibility it gives us into every element of the system, is what keeps everything working.

Where We Work

We have designed and installed networks in some of the most demanding residential environments in the world. A selection:
Large London townhouses — multi-storey properties with thick masonry construction, basements, and rooftop terraces requiring coverage at every level
Country estates — multiple buildings, extensive grounds, outbuildings, and shooting ranges requiring long-distance wireless links between structures
Alpine ski chalets — thick timber and stone construction, extreme temperature variation, limited cable access, and owners who need everything working perfectly the moment they arrive
Dubai villas — extensive grounds, multiple villa structures, pool and garden coverage, high ambient temperatures requiring carefully specified outdoor equipment, and integration with large-scale Crestron automation systems
Grade I and Grade II listed properties — where cable routes must be agreed with conservation officers and installed with exceptional care for the fabric of the building
New builds at the planning stage — where we advise on conduit infrastructure, equipment room location, and cable routing to ensure the network is built in correctly from the start.

Common Questions

Do I need to rewire the house to get a good WiFi network? Not necessarily. For existing properties where running cable everywhere is impractical, a well-designed hybrid or mesh system delivers genuinely impressive results. The key is professional survey and design — the same equipment installed poorly will underperform significantly. We assess every property individually and recommend the approach that delivers the best result for its specific constraints.
How many access points do I need? This depends entirely on the size and construction of the property, the number of floors, the extent of outdoor areas to be covered, and how many devices need to be served simultaneously. We size every network from the survey data — we do not apply rules of thumb or standard packages. Some properties require two or three access points. Others require fifteen or more.
Will the network work with my existing smart home system? In almost all cases, yes. We work regularly with existing Crestron, Control4, Savant, Lutron, and other smart home platforms. We assess the network requirements of the existing system and design accordingly. Where an existing network is causing unreliability in the smart home system, we can diagnose and resolve the issue — either by optimising the existing infrastructure or by replacing it.
Can you connect separate buildings on the same property? Yes. We regularly design networks that link main houses, guest cottages, garages, pool houses, and other outbuildings on the same property, either over buried Ethernet cable, fibre, or — where cabling is not practical — high-performance point-to-point wireless links. All buildings share the same network and appear to every device as a single, seamless connection.
How quickly can the network be installed? A straightforward installation in an existing property typically takes one to two days. Larger or more complex projects — new builds, multi-building estates, or projects with extensive cable infrastructure — are planned and scheduled in detail and typically form part of a broader technology installation programme.

Projects

Case Study 1:Enterprise WiFi & Security Network — Private Estate, Dubai
As part of a major Crestron smart home installation across two villas and extensive grounds, we designed and installed an enterprise-grade gigabit network with access points throughout the villas, garden, pool area, and basketball court. HD IP CCTV cameras ran over the same network infrastructure. The system supports eight Crestron processors, seventy-two audio zones, and full 4K video distribution simultaneously — with no performance degradation. Read the full case study
Case Study 2: Wired WiFi Installation — Alpine Chalet, Morzine
A substantial chalet in the Morzine area presented a classic challenge: six floors of thick timber and stone construction, including a basement cinema room and rooftop terrace, with an owner who required flawless connectivity throughout — including the garage and garden. A fully wired PoE network with enterprise access points delivered consistent performance across the entire property, integrated with the CCTV and smart home systems.
Case Study 3: Whole Home Wifi Installation — Country Estate, Derby
This large country estate in Derbyshire came with all the usual challenges: huge amounts of space to cover and a new home with construction challenges such as steel frames, foil backed insulation and acres of underfloor heating. A full smart home system needed the network to perform flawlessly. Read the full case study.
