Planning the Ultimate Future-Proof Home Network

Abi and I have been saving for a deposit to buy our first home, and with that comes the inevitable updates from various property search sites. It's a bit of a dream, isn't it? Scrolling through Rightmove and imagining where the sofa will go—or more importantly, where the server rack will go (I know, I’m a romantic).

We recently got an email about a property slightly down the street from where we are now. Since our current location is perfect for town and seeing family, it seemed like a good opportunity to do a bit of investigating. The house itself needs a bit of work to bring it into modern times—a bit of rewiring, some plastering, maybe a kitchen update—and we’re certainly not scared of getting our hands dirty (though I fully expect my back to be less enthusiastic than my brain come moving day).

But, between you and me, the real excitement started when I began thinking about the infrastructure.

One of the things Abi has somewhat agreed to (read: hasn’t said yes, but also hasn’t said no, which is a green light in my book) is allowing me to add wired networking throughout any property we buy. Honestly, I have a bit of an aversion to Wi-Fi when it comes to my own devices. It’s like a temperamental teenager; sometimes it's great, but other times you’re left shouting at it from the next room. There’s always something blocking a signal. I shouldn’t have to hope my mobile data works when I’m sat on the loo because the Wi-Fi signal reaches the bathroom door and gives up. We all know that moment of digital despair when the little spinning wheel of doom appears.

Having a wired network throughout the house future-proofs the property for decades and allows me to finally have a mini server rack in my office and a proper network cabinet tucked under the stairs. Our smart TV will never have issues playing back content from our local media server due to a dodgy wireless connection. I want the experience to be as smooth as a freshly rendered 3D model, not a stuttering mess.

Phase 1: Planning, Pixels, and Plenty of Panic

When we looked at the listing for the property, the agents handily included a floor plan with reasonably accurate measurements. This is where my obsession kicks in. I did what I always do when I see a possible project in my future: I got Blender up and running and created a detailed 3D model of the house.

You might be thinking, "Jim, isn't a 2D floor plan enough?" Technically, yes, but where is the fun in that? Building the 3D model lets me visualise the space properly, figure out line-of-sight for wireless access points, and, most critically, map out exactly where the cables are going. When you’re dealing with older properties where every internal wall is thick, dense brick—the kind of brick that seems engineered purely to thwart wireless signals—you need to know if that 30–50mm plaster-and-brick wall is going to cause a problem. Plus, creating a digital twin means I can virtually rip out walls and relocate sockets before we even buy a tin of paint. It's pure gold for my high-functioning planning anxiety.

Whilst we don’t own the house yet and have a year or so to go until our savings match what we need for a deposit, the exercise has been great for figuring out exactly what we would do with a similar space in the area.

The Conduit Conundrum

If we are going to be tearing up floorboards and chasing walls (which is necessary in a house this age), we need to ensure the stuff we put inside the walls won't need replacing for another twenty years. We're not just running basic Cat5e; we need to run Cat6a everywhere, alongside a few strategic Fibre-Optic backbones.

The crucial part here is conduit. You run the conduit pipe first, and then you pull the cable through. This is the difference between a one-time renovation pain and a lifelong nightmare. If Cat6a's 10 Gigabit Ethernet (10GbE) capability is replaced by 25GbE or 40GbE in the next decade, I only need to pull the new cable through the existing tubes. By making the main backbone of the network a fibre run, all we should need to do is upgrade the SFP+ modules to the latest standard down the line, saving an immense amount of structural work.

Anecdote Time: My first ever attempt at a "proper" home network involved stapling a beige Cat5 cable to the skirting board in the hallway. It looked terrible, and when I tried to upgrade it years later, I accidentally stapled through the new cable's jacket. Total disaster. Never again. Now, it’s all about smooth, subterranean, future-proof pathways.

Phase 2: The 10GbE Backbone – Our Digital Motorway

With the virtual house built and a mountain of theoretical cable measured out, it was time to head over to the Ubiquiti store and see what the UniFi ecosystem had to offer. I love UniFi because it gives you enterprise-level control without the enterprise-level complexity or price tag.

1. The Internet Gatekeeper: Cloud Gateway Max (£387.60)

The first thing to consider was getting the internet from the outside world into the property. Thankfully, the full street has Fibre-to-the-Home (FTTH) options using both Openreach providers and KCOM.

To avoid bottlenecks, I looked into the Cloud Gateway Max. It’s a compact 10G gateway featuring multi-gigabit routing, selectable local NVR storage for security footage, and full UniFi application support:

• UniFi Network: The core brain managing everything, providing real-time traffic insights and a visual network topology.
• UniFi Protect: The AI-driven camera platform that records high-quality video to local storage.
• UniFi Talk & Access: Ready for the future if we ever want to add smart door access or internal VOIP systems.

It handles all the routing cleanly and gives me a massive 10Gbps link potential to the rest of the house, keeping my options open for ludicrously fast ISP upgrades down the line.

2. The 10Gbps Aggregator: UniFi Aggregation Switch (£258.00)

While the gateway handles the routing, it doesn't have enough ports to distribute a high-speed backbone across the whole house. Enter the UniFi Aggregation Switch.

Think of it this way: the internet pipe is the main road coming into the city. The Cloud Gateway is the main toll booth checking traffic. The Aggregation Switch is the main roundabout, ensuring data can get onto the smaller, but still very fast, distribution roads (the edge switches). This beautiful 8-port Layer 2 switch is built entirely for 10G SFP+ connections, acting as our central digital motorway junction.

Phase 3: The Edge Switches – 2.5GbE to the People

Now that we have the Aggregation Switch distributing our 10GbE fibre backbone, we need edge switches to convert that back into standard copper Ethernet cables that ordinary devices can use.

To keep things simple and flexible, I selected five UniFi Flex 2.5G PoE Switches (£190.80 each). They feature 10G uplinks back to the central aggregator and provide 8x 2.5GbE ports with Power over Ethernet (PoE++) capability. 2.5GbE is the current sweet spot—it prevents bottlenecks when moving large 4K video files or local backups, and it is natively supported by modern laptops and access points.

Here is how the five-switch topology breaks down across the property:

1. The Network Cupboard Switch (Under the Stairs)

This is the silent workhorse for core devices that don't need daily user interaction. It lives tucked away under the stairs and handles:

• Cables running to the infrastructure points in the hall, kitchen, and back porch.
• Outdoor garden and side-of-house security cameras.
• Utilises PoE++ to power everything over a single network cable, completely eliminating ugly power bricks.

2. The Living Room Switch (The Media Hub)

Positioned neatly behind the TV cabinet, this switch provides the ultra-low latency connections essential for media consumption and gaming:

• Connectivity for the living room and dining room access points.
• Hardwired lines to the PlayStation 5, set-top boxes, and the Smart TV.
• A dedicated port for our streaming media players so we never have to deal with interface lag or buffering.
• Note: I refuse to blame my terrible Call of Duty skills on a dodgy Wi-Fi connection when a wired link is right there. It's a matter of principle.

3. The Bedroom Switch

This switch brings reliable connectivity to the upstairs sleeping quarters and my reading nook:

• Feeds the upstairs Wireless Access Points.
• Provides wired lines for future additions, like the kids' computers as they grow up or bedroom smart TVs.
• Generally stays completely silent, only humming to life when we're watching a bit of television before dropping off to sleep.

4 & 5. The Office Switches (The Nerve Centre)

The office is where my projects live, meaning it gets a "double-tap" of two entirely separate switches to isolate my workflows.

• Office Switch 1 (Infrastructure & Backhauling): Dedicated to core network expansion, the office cameras, and our primary Network Attached Storage (NAS).
• Office Switch 2 (The Playground): Dedicated to daily-use equipment. This connects my remote work computer, my personal machine (used for tinkering with LLMs and 3D rendering), and the dedicated Home Assistant hub running our smart home automations.

Phase 4: Wireless and Security Overkill

1. The Brick Wall Conquerors: UniFi U7 Pro WAPs (£190.80)

Because the internal walls are dense brick, pushing a wireless signal through them is like shouting through a waterlogged mattress. To combat this, practically every major zone has its own ceiling-mounted UniFi U7 Pro Wi-Fi 7 Access Point. They include fantastic management features:

• Band Steering: Automatically pushes capable devices onto the less-cluttered 5GHz and 6GHz bands.
• Fast Roaming (802.11k/v/r): Smoothly hands your phone off from the office to the kitchen as you walk around without dropping video calls.
• Guest Isolation: Keeps visitors completely isolated from my private home lab equipment.

2. The Vigilant Eyes: UniFi G5 Turret Ultras (£94.80)

For external security, I've opted for UniFi G5 Turret Ultra cameras. They are weatherproof, tamper-resistant 2K HD PoE cameras. Anything less than 2K is useless when you actually need to see fine details.

• Features local AI-driven detection for people and vehicles (no more false alerts from blowing leaves).
• Built-in microphones that can detect standard smoke/CO alarm sirens and send an instant push notification to our phones.
• Can be linked directly into Home Assistant to trigger outdoor lighting automations when motion is detected after dark.

3. The Welcome Mat: G4 Doorbell Pro PoE (£360)

Completing the entry security is the G4 Doorbell Pro PoE. It features a main camera alongside a dedicated package camera pointing downwards, an integrated speaker, and an NFC reader. It runs entirely over a single PoE cable, making it a robust, beautifully reliable doorbell that integrates cleanly into our local monitoring setups.

Phase 5: Data, Drives, and Digital Hoarding

All this high-definition surveillance and local media backup needs a secure home. We can't just save hours of security footage to a sketchy USB stick plugged into the back of a router.

1. The Footage Vault: UniFi Network Video Recorder (UNVR) (£286.80)

To manage our camera feeds cleanly without slowing down a desktop computer, I've budgeted for the 4-bay UniFi NVR. It connects directly to the central Aggregation Switch via a 10GbE SFP+ port, ensuring massive video traffic never clogs up the rest of the household network. It features full RAID protection; if a hard drive mechanically fails, the data remains safely mirrored on the others.

The storage scaling math looks like this:

• 4 x 24TB Drives: ~112 days of continuous 2K footage.
• 4 x 16TB Drives: ~74 days of continuous footage.
• 4 x 8TB Drives: ~37 days of continuous footage.

We will likely aim for the 8TB or 16TB sweet spot using proper, mechanical NAS-rated drives (like WD Red Pro or Seagate IronWolf) designed for constant 24/7 write cycles.

2. The Local Media Server: UniFi NAS (£360)

The final piece of the puzzle is a compact, 4-bay Network Attached Storage (NAS) device powered directly over PoE. It features M.2 NVMe SSD slots for caching and standard drive bays for storage.

This will allow me to centralise all of our family files and personal code repositories locally, rather than relying on external cloud providers. I've strictly embraced the local, self-hosted, no-cloud-required model ever since my old commercial plug-and-play NAS unfortunately bricked itself during a forced firmware update. Having total data sovereignty over our own files is a massive win.

Final Thoughts

The process requires a lot of upfront planning, structural wall-chasing, and an admittedly substantial hardware budget. However, building a rock-solid, hardwired foundation ensures that our home network will remain blisteringly fast and totally reliable for decades to come.
