Opening a new office is an exciting milestone for any organization. It represents growth, new opportunities, and the next step in your business’s evolution. But before employees move in and operations begin, it’s important to make sure your network infrastructure is ready to support the new location.
Too often, network planning becomes an afterthought during an office expansion. By the time IT is asked to evaluate connectivity, internet service, or network design, project timelines are already compressed and options may be limited.
Planning your network early helps avoid delays, supports employee productivity from day one, and ensures your technology can grow alongside your business.
Key Takeaways
- Start network planning as soon as a new office location is being considered, ideally 90 to 120 days before opening.
- Confirm fiber availability and carrier options before signing a lease whenever possible.
- Evaluate bandwidth, security, voice services, and WAN connectivity as part of your expansion plan.
- A structured network assessment helps prevent delays and unexpected costs.
- PSM Partners helps organizations design, deploy, and optimize network infrastructure for new office locations.
Why Network Planning Should Start Before You Sign a Lease
One of the biggest mistakes organizations make during an office expansion is waiting until after the lease is signed to involve IT.
A building may check every box from a real estate perspective, but that does not always mean it offers the connectivity your business requires. Internet providers, fiber availability, installation timelines, and building infrastructure can vary significantly from one location to another.
Bringing IT into the planning process early allows your team to evaluate network options before key business decisions are finalized. In some cases, connectivity limitations may even influence which location is the better long-term fit.
Evaluate Connectivity at the New Office
Before making any decisions, determine what internet services are actually available at the building.
Important questions include:
- Is dedicated fiber available?
- Which carriers service the building?
- What are the installation lead times?
- Are redundant internet connections available?
- Does the building support future bandwidth growth?
While dedicated fiber is often the preferred solution for businesses that rely on cloud applications, VoIP, and video collaboration, availability varies by address. Some locations may require new construction or extended installation timelines, making early planning essential.
Determine Your Bandwidth Requirements
Choosing the right internet circuit is about more than employee headcount.
Today’s businesses rely on cloud applications, video conferencing, file sharing, VoIP, and SaaS platforms throughout the workday. These applications all consume bandwidth differently.
When estimating bandwidth requirements, consider:
- Number of employees
- Expected video conferencing usage
- Cloud applications
- File storage and backup traffic
- Guest Wi-Fi
- Future business growth
Symmetrical bandwidth, where upload and download speeds are equal, is often the best choice for organizations that depend on cloud collaboration tools and video meetings.
Plan How the New Office Connects to Your Existing Network
A new office should become part of your overall network strategy, not operate as a standalone location.
As you evaluate your network architecture, consider:
- How will employees securely access company resources?
- How will traffic reach cloud applications?
- Will the location connect through SD-WAN or another WAN solution?
- How will network performance be monitored?
Many organizations use SD-WAN to simplify connectivity between multiple offices while improving application performance and providing greater flexibility as the business grows.
Extend Your Security Strategy to the New Office
Every office should follow the same security standards as the rest of your organization.
Before opening the new location, verify that:
- Firewall policies are consistent across locations.
- Guest Wi-Fi is separated from business traffic.
- Employees have secure access to corporate resources.
- Endpoint management is in place.
- Industry compliance requirements are met.
Incorporating these controls during deployment is much easier than making changes after employees have already moved into the space.
Don’t Overlook Voice and Collaboration
Reliable communications are essential for employee productivity and customer service.
If your organization uses Microsoft Teams, Zoom Phone, RingCentral, or another UCaaS platform, make sure the network is designed to support voice and video traffic.
Planning should include:
- Quality of Service (QoS) policies
- Phone number provisioning
- Internet redundancy
- Call routing
- Testing before employees arrive
A little preparation can prevent frustrating call quality issues once the office is operational.
Verify the Physical Infrastructure
A strong network depends on more than internet service.
Before opening the office, evaluate:
- Network closets and rack space
- Structured cabling
- Wireless access point placement
- Power availability
- Cooling requirements
- Equipment installation
A site survey can identify potential issues early and help ensure the physical infrastructure supports your network design.
New Office Network Planning Checklist
Before your office opens, make sure you’ve completed the following:
- Verify fiber availability and carrier options.
- Estimate bandwidth requirements based on applications and future growth.
- Design how the office will connect to your existing network.
- Extend firewall, endpoint, and security policies.
- Plan voice and collaboration services.
- Validate cabling, wireless coverage, and equipment locations.
- Schedule carrier installations early to avoid delays.
- Test network performance before employees move in.
Common Mistakes During Office Expansions
Organizations can avoid many common networking challenges by planning ahead.
Some of the most frequent issues include:
- Waiting too long to order internet service.
- Underestimating bandwidth requirements.
- Treating the office as an isolated network instead of part of the corporate infrastructure.
- Assuming the building’s cabling and network rooms meet business needs.
- Waiting until opening day to test voice, Wi-Fi, and application performance.
Addressing these items early helps keep projects on schedule and minimizes disruptions after employees arrive.
