A shared use space needs a network that can support multiple companies in one building without allowing one company to access another company’s systems.

The goal is to provide shared internet and building services while keeping each tenant’s network separate and secure.

Recommended Infrastructure

Internet Connection

Use a business-grade fibre connection where possible. If the internet is critical, add a second connection using another provider or a 4G/5G backup.

Router and Firewall

Use a business-grade router or firewall that supports VLANs, firewall rules, VPN access, reporting, and multiple networks.

Managed Switches

Use managed switches that support VLAN tagging. This allows each company, wireless network, printer network, and shared service to be separated.

Wireless Access Points

Use business-grade wireless access points that support multiple SSIDs. Each SSID should connect to the correct VLAN.

Example wireless networks:

Company A Wi-Fi
Company B Wi-Fi
Guest Wi-Fi
Building Management Wi-Fi
Admin Wi-Fi

VLAN Setup

Each company should have its own VLAN.

Example:

VLAN 10 – Management
VLAN 20 – Company A
VLAN 30 – Company B
VLAN 40 – Company C
VLAN 50 – Guest Wi-Fi
VLAN 60 – Printers
VLAN 70 – CCTV
VLAN 80 – Phones

Guest Wi-Fi

Guest Wi-Fi should only allow internet access. It should not allow access to printers, computers, servers, CCTV, or other company networks.

Shared Printers

If printers are shared, place them on a separate printer VLAN and allow only approved companies to access them.

CCTV and Access Control

CCTV and door access systems should be isolated from normal user networks.

Documentation

Keep a record of:

VLAN numbers
IP address ranges
Switch port assignments
Wi-Fi names
Firewall rules
Admin passwords
Device locations
Support contacts

A shared use space should be designed for separation, security, and easy management. Each company should have its own private network while still being able to use shared services where approved.
