Smart Homes & Building Automation

ARN Projects designs and delivers smart custom built homes that feel effortless from day one. Led by Arron Dewhurst, the team integrates home automation, connected devices, sensors and smart HVAC into a single, reliable control ecosystem that is planned, engineered and commissioned for long-term performance.

Why Intelligent Control Belongs in the Build Brief

Smart technology should not be added as an afterthought. It should be designed into the fabric of the home. When automation, structured wiring and building services are coordinated early, the result is cleaner architecture, fewer compromises and a system that simply works.

ARN Projects leads this process from the first concept meeting, aligning the controls strategy with the architectural vision, MEP design and client priorities such as comfort, energy efficiency, security and future-ready flexibility.

A Single, Coherent Ecosystem, Not a Box of Gadgets

The difference between a collection of gadgets and a smart home is integration. ARN Projects specifies platforms and open protocols that allow lighting, heating, cooling, ventilation, shading, security, audio visual, EV charging and renewables to share data and respond as one system.

Scenes can adjust multiple systems with a single command, sensors can trigger real-time responses, and the central app provides clear, secure control. The result is simplicity for the homeowner and dependable performance behind the scenes.

Structured Cabling and Backbone Design

Reliable automation starts with the right connected services infrastructure for modern living . The team designs a resilient low-voltage backbone alongside the electrical installation, including:

  • structured cabling for data, control and PoE devices
  • distribution and containment planned with the same discipline as mains power, avoiding bottlenecks and afterthought trunking
  • network architecture sized for HD streaming, cloud services and local control, with business-grade Wi-Fi, controller-based roaming and a tidy comms rack
  • power quality considered from the start, with surge protection, UPS for critical nodes and clean separation of circuits to reduce interference

This foundation is what separates a home that is only occasionally smart from one that is consistently reliable.

Sensors That Make the Building Think

Good automation is driven by useful data. ARN Projects deploys sensors that capture what matters and ignore what does not, including:

  • presence and occupancy sensing to drive lighting, security modes and setback temperatures
  • lux and daylight sensing to adjust artificial lighting and automate blinds for glare control
  • temperature, humidity and CO2 monitoring to optimise heating, cooling and MVHR rates for healthy indoor air quality
  • window and door contacts to pause heating when rooms are being aired and to trigger security scenes automatically
  • energy meters to monitor loads, PV generation and battery state, feeding dashboards that help homeowners make informed decisions

The system responds to these inputs locally, so routine automations continue even if the internet connection is lost.

Lighting Control That Shapes Mood and Wellbeing

Lighting is often where clients feel the value of automation most clearly. ARN Projects designs layered lighting with ambient, task and accent elements, then tunes it with scenes suited to real life, such as Welcome, Relax, Cook and Entertain. Dimming curves are smooth and flicker-free, colour temperature can follow the time of day, and engraved keypads replace wall clutter with simple controls.

Motion-assisted pathways at night improve safety while using very little energy. Everything remains manually controllable, because a well-designed interface should never get in the way of a switch that simply works.

Smart HVAC, Renewables and Thermal Comfort

Comfort and efficiency work best together when controls are designed around the actual behaviour of the building. ARN Projects integrates:

  • zoned heating, including underfloor heating and radiators, with smart thermostats and room-by-room scheduling
  • heat pumps coordinated with weather compensation and occupancy patterns
  • MVHR and ventilation rates adjusted according to humidity and CO2 thresholds for quieter, healthier air
  • shading control to reduce solar gain before active cooling is required
  • photovoltaics, battery storage and EV charging set up to optimise self-consumption and off-peak tariffs

The result is more stable temperatures, cleaner air and a measurable reduction in wasted energy without constant adjustment from the user.

Shading, Glazing and Façade Intelligence

Motorised blinds and external shading are not simply luxury additions. They are important tools for both thermal and visual comfort. Daylight sensors and sun-path logic automate blinds to limit screen glare, protect finishes from UV and support passive cooling.

In winter, blinds can open to make use of solar gain. Every setting can be overridden instantly from a keypad or app, but most clients find they rarely need to.fessional operation, not chaos.

Security That Feels Discreet but Decisive

Security should provide reassurance, not stress. ARN Projects integrates CCTV, access control, door stations, gate automation and perimeter sensors into calm, coordinated logic. Presence simulation can run while the house is unoccupied.

Notifications are filtered so only relevant alerts are sent, grouped to reduce unnecessary noise. Guests can be issued temporary access codes, while gate and garage actions can trigger lights and welcome scenes. Data is encrypted end to end, and recordings are stored securely on site with optional cloud backup.

Interfaces You Will Actually Use

Control should be intuitive. The team designs interfaces to suit different situations, with minimal keypads in living spaces, a fuller tablet view for whole-house control and a secure app for off-site access.

Voice control is available, but never required. There is always a local, tactile way to switch, dim, open or close, because reliability and accessibility matter more than novelty.

Open Standards, Future-Proof Choices

Technology changes quickly, but homes are built to last. ARN Projects prioritises open protocols such as KNX, BACnet, Modbus, Zigbee, Thread, Matter and MQTT bridges where appropriate, alongside vendor-neutral design.

This helps avoid lock-in, makes phased upgrades easier and supports integration with third-party systems over time. Critical devices continue to operate locally, while cloud services add convenience rather than becoming the foundation of the experience.

Cybersecurity and Data Privacy by Design

A smart home forms part of your digital life and should be protected accordingly. ARN Projects implements network segmentation, role-based access, strong authentication and secure remote support. Firmware updates are controlled and tested.

Cameras, doorbells and intercoms are configured with privacy-conscious defaults. Clients receive plain-English guidance on best practice, supported by documented network maps and sensible credentials management.

Commissioning, Testing and Handover

A polished result depends on careful commissioning. Every scene, trigger and schedule is tested in real scenarios, including daylight, dusk, night-time, occupied and unoccupied conditions. Heating curves are tuned across different weather conditions. Wi-Fi coverage is checked using heat maps and adjusted before handover.

ARN Projects supplies a clear Home Technology Manual containing wiring schedules, device inventory, network diagrams, warranties and service contacts, along with household training. The first months of occupancy include fine-tuning so the home feels natural rather than newly installed.

Retrofit Without the Rip-Out

Not every project is a new build. ARN Projects also delivers retrofit-friendly solutions such as wireless keypads, battery-efficient sensors and hub-based lighting in selected areas, supported by strategic cabling where it matters most, including the comms rack, access points, EV charger and camera runs. The approach is practical: minimum disruption, maximum benefit and a clear route for future phases.

Energy Dashboards That Drive Better Decisions

Seeing where energy is used changes behaviour. Real-time dashboards can display whole-house consumption, circuit-level loads, PV generation and battery status.

Clients can compare rooms, identify standby waste and set alerts for unusual spikes. The emphasis is on clarity rather than gimmicks, giving useful insight that translates into lower bills and a smaller environmental footprint.

Service, Support and Lifecycle Care

Automation is a living system rather than a one-off installation. ARN Projects provides planned maintenance, remote monitoring and responsive support.

Minor adjustments such as new scenes, revised schedules or updated tariffs can often be handled quickly without a site visit. Firmware and security updates are managed as part of a service plan, helping keep the home current and secure.

Frequently Asked Questions

Do I need to decide on a control platform before planning permission?

It helps to decide early. The platform influences wiring, containment and the space required for racks and plant. Late changes can be expensive, while early clarity keeps the build tidy and future-ready.

Will everything still work if the internet drops?

Yes. Core functions such as lighting, heating, shading and security are designed to run locally. Remote features and cloud services add convenience, but they are not required for day-to-day use.

Can you integrate my preferred brands and devices?

In many cases, yes. ARN Projects prioritises open standards and proven integrations. Where a device is too closed or unreliable, alternatives are recommended with clear advantages and drawbacks explained.

What about voice control? Do I have to use it?

Not at all. Voice control is optional. Physical keypads and app control are always provided, with interfaces designed for simplicity and accessibility.

Is a smart home secure?

It can be, when engineered properly. ARN Projects uses segmented networks, strong authentication, encrypted links and disciplined update policies. Security is treated as a core design requirement, not an afterthought.

Can you retrofit a period property without damaging finishes?

Yes. Through careful surveying, wireless solutions, selective cabling and discreet containment, ARN Projects can upgrade technology with minimal disruption and a conservation-minded approach.

How much maintenance will my system need?

Usually very little day to day. Planned check-ups, remote monitoring and occasional firmware updates keep everything running as it should. Most adjustments can be made quickly and with minimal disruption.
