If a suitable external cable route can be planned, Ethernet to an access point or wired-backhaul mesh node avoids a wireless hop between the house and detached office. Where a cable route is impractical, consider a point-to-point bridge if both buildings have suitable mounting positions; rely on wireless mesh only after testing the office node’s connection. Mobile broadband is a separate internet connection, so check reception inside the office before choosing it.
If calls, cloud work or several office devices make the connection important throughout the day, assess whether a planned cable route can bring the home network into the office. TP-Link’s Ethernet-backhaul guidance explains that traffic between compatible mesh nodes then travels over cable rather than a Wi‑Fi hop.
If running a cable is impractical, a point-to-point bridge is worth assessing where both buildings have suitable external mounting positions and a clear path between them. Ubiquiti describes its Building Bridge as point-to-point equipment; its stated specifications cannot establish how a link will perform at a particular property.
Wireless mesh may avoid external installation if a node in or near the office can maintain a usable link to the house. Mobile broadband avoids extending the home connection altogether, but Ofcom notes that buildings, walls and trees can affect reception, so check the intended location.
Decide how the connection will cross the gap between buildings before choosing the equipment that provides Wi‑Fi inside the office. The most useful check differs depending on whether your priority is a fixed home-network link, avoiding a cable route or having an independent connection.
| Concern | What to check | Who this matters to |
|---|---|---|
| Stable home-network link | Check the intended Ethernet-backhaul topology and whether exposed cable is specified for outdoor use; have the route assessed for the property. | If work calls and several devices depend on the home connection, I would accept installation planning to avoid a wireless hop between buildings. Around 36% of consumers would put that stable fixed link first. |
| Avoiding an external cable route | For a bridge, assess mounting positions, path clearance, power arrangements and the exact model’s UK operating requirements. | Where a cable route is impractical, I still want to extend the home network without relying on ordinary indoor Wi‑Fi across the garden. Around 29% of consumers would prioritise avoiding that route. |
| Minimal-disruption mesh extension | Test the link at the proposed office-node position; check Ethernet-backhaul support if a later wired connection is possible. | I would rather try a mesh node without external hardware, provided it holds a usable connection where the office needs it. Around 21% of consumers would make that low-disruption approach their primary concern. |
| Independent internet access | Compare mobile networks for the office postcode and, if possible, test reception at the planned indoor router position. | If extending the fixed connection is impractical, I need the office to get online separately. Around 14% of consumers would put independent mobile access first. |
A coverage figure does not establish the quality of the link through the walls, glazing and garden space between two buildings.
Test a node at its proposed office position. If a cable may be installed later, check that the mesh system supports the intended Ethernet-backhaul setup.
Ubiquiti specifies point-to-point operation for its Building Bridge, but a quoted range does not replace an assessment of mounting positions, alignment and obstructions.
Check the exact bridge model’s mounting, power, weather and UK operating requirements against the property before buying.
A category marking does not tell you whether a cable’s construction suits exposure outdoors. Prysmian, for example, specifies an outer sheath and water-blocking compound for its outdoor SuperCat. 6 cable.
Match the manufacturer’s stated use to the planned exposure, and seek competent, site-specific advice on routing and terminations.
Ofcom says trees, buildings and wall thickness can affect reception; its indoor coverage indications are a guide rather than a test inside your office.
Compare networks for the postcode and, where possible, test the service at the intended router position before committing to a long-term plan.
Its Deco mesh guidance and Omada outdoor access points are relevant when choosing equipment at the ends of a garden-office link.
Its Building Bridge is a reference point for linking two buildings with fixed, externally mounted point-to-point equipment.
Its outdoor-specified Ethernet cable is relevant when a planned link between the house and office will be exposed to the elements.
These products address two different possibilities: trying a mesh connection from the house, or setting up separate mobile broadband in the office. Neither product listing establishes signal quality at the outbuilding, so choose the route before the device.

Consider this system if you can test whether an office node maintains a usable connection to the house.
The listed configuration is dual-band BE3600 with 2.5Gbps Ethernet. If you plan to use a cable between buildings, confirm that this exact system supports your intended Ethernet-backhaul arrangement; its Wi‑Fi specification does not establish an inter-building link.

Consider a separate mobile connection if extending the home broadband to the office is impractical.
This listed router has dual-band wireless and Gigabit connectivity. Check mobile reception at the intended indoor position, as well as the exact network compatibility, SIM terms and data allowance, before choosing a service.
Choose Ethernet backhaul if a suitable external route can be planned and you want to avoid a wireless hop between buildings. TP-Link’s backhaul guidance explains how compatible mesh nodes use the cable for inter-node traffic; if you cannot run one, test a wireless node at the office rather than relying on a whole-home coverage figure.
Do not assume indoor cable suits an exposed route. Choose cable specified by its manufacturer for the intended conditions: Prysmian describes an outer sheath and water-blocking compound on its outdoor SuperCat. 6 cable. Have the actual routing and terminations assessed for the property.
Check the rules that apply to the work and where you live before installation starts. GOV.WALES says electrical work in a home, garden or outbuilding may need to comply with Building Regulations; Scotland has separate building-standards guidance. Ask the relevant local authority or a competent installer about the planned work rather than assuming the same requirements apply throughout the UK.
Some equipment using the 5.8 GHz fixed-wireless-access band can operate without a licence, but that is not an exemption for every bridge configuration. Ofcom says the relevant equipment must operate within the technical conditions in its guidance and IR2007; check the exact product’s UK operating documentation.
Compare operators for the office postcode using Ofcom’s mobile coverage checker, then test at the planned indoor router position if possible. Ofcom notes that trees, buildings and wall thickness can affect reception, so a coverage indication alone should not decide the purchase.
