Shell Buildings, White Box, or Tenant Improvement? How Columbus Landlords Can Future-Proof Commercial Spaces
Commercial landlords and developers in Columbus hear the same terms over and over: shell building, white box, vanilla box, or tenant improvement. They are often used interchangeably, even though they mean very different things. That confusion can lead to misaligned expectations, slower lease-ups, and added cost once a tenant is signed.
Understanding these distinctions helps property owners deliver the right level of readiness, attract better tenants, and plan maintenance and small projects with intention.
This guide breaks down each option clearly and explains how landlords in Central Ohio can make smarter decisions that support both leasing and long-term property care.
Start with the Right Question: Who Is This Space For?
Before defining terms, there are two separate decisions every owner should make:
- Who is the space intended for? (speculative vs. known tenant)
- How finished should the space be when delivered?
These are often blended, but they shouldn’t be.
A speculative building can still be delivered as a white box.
A committed tenant space can still require a full build-out.
The most successful projects align these decisions early.
The Spectrum of Delivery: From Shell to Full Build-Out
Rather than thinking in isolated terms, it’s more useful to view commercial spaces as a spectrum of completion.
Shell Building
A shell building is delivered with the base structure and core systems in place, but without interior finishes or tenant-specific build-out.
In Central Ohio, shell spaces typically include:
- Structural frame, exterior walls, and roof
- Utilities brought to the space or stubbed for future connection
- Limited or no interior partitions
- Minimal or non-operational HVAC distribution
- Unfinished floors and open ceilings
When it works:
- Multi-tenant developments with unknown future uses
- Projects prioritizing flexibility over speed to lease
- Tenants with highly specific layout or infrastructure needs
Tradeoffs:
- Longer lease-up timelines
- Higher upfront cost for tenants
- Greater risk of scope gaps during negotiation
White Box (Cold vs. Warm)
A white box—also referred to as a vanilla box—is a partially finished space designed to be more immediately leasable.
Cold White Box
A cold white box typically excludes key mechanical, electrical, and plumbing (MEP) systems.
It may include:
- Framed walls without drywall
- Electrical service to a panel only
- Exposed ceilings for future MEP runs
- Concrete floors with leave-outs for future utilities
This approach is common in new construction and adaptive reuse—like projects such as Aardvark Wine & Beer Dive Baar—where flexibility is critical.
Note: MEP systems often account for 40–70% of a tenant’s total build-out cost, so when they are excluded, a significant financial burden shifts to the tenant.
Warm White Box (Vanilla Box)
A warm white box is a more complete, functional version of the space.
Typically includes:
- Finished drywall with neutral paint
- Installed lighting
- Operational HVAC system
- Ceiling system (or finished open ceiling)
- Level floor surface (finished or ready for flooring)
These spaces are often found in repositioned buildings or second-generation spaces like Waterloo One.
Why landlords choose this approach:
- Faster lease-up
- Lower tenant hesitation
- Broader market appeal
- Tenants spend more on brand/finish, less on infrastructure
For many properties, this represents the best balance between upfront investment and leasing performance.
What Are Tenant Improvements?
Tenant improvements, often called TIs, are build-outs tailored to a specific tenant’s use, brand, and operations. These can range from light finish changes to full interior construction.
Tenant improvements may include:
- Interior partitions and private rooms
- Custom lighting layouts
- Flooring specific to the business
- Restroom upgrades
- Mechanical zoning adjustments
In Columbus, tenant improvements are common in hospitality, medical offices, retail, and professional services.
Landlord vs Tenant Responsibility
Tenant improvements can be landlord-funded, tenant-funded, or shared. Clear documentation and early coordination help avoid delays once permits and inspections begin.
How Landlords Can Choose the Right Approach
The right level of build-out depends on tenant type, market conditions, and long-term ownership goals.
Questions Worth Answering Early
- Who is the most likely tenant for this space?
- How quickly does the space need to lease?
- What level of customization is expected in this submarket?
- How does this building fit into the broader portfolio?
In fast-growing Columbus neighborhoods, landlords often benefit from delivering a white box while planning for small upgrades between tenants.
A Practical Rule of Thumb
- Shell: Maximum flexibility, slower lease-up
- Cold White Box: Flexible but shifts cost to tenant
- Warm White Box: Faster leasing, broader appeal
- TIs: Best for committed tenants, highest customization

The Role of Ongoing Maintenance and Small Projects
Initial construction is only part of the story. Buildings evolve over time, and the most successful properties are designed with turnover and adaptability in mind.
Common small projects landlords face include:
- Patching and repainting between tenants
- Flooring repairs after heavy use
- Lighting updates to meet new expectations
- HVAC tuning and zoning corrections
- Restroom fixture replacements
Having a local contractor familiar with the building allows these updates to happen quickly and consistently.
How Future-Proofing Protects Property Value
Future-proofing does not require major renovations every cycle. It often means maintaining flexibility and addressing small issues before they grow.
Examples include:
- Keeping base building systems in good working order
- Choosing durable finishes in common areas
- Updating lighting as standards change
- Refreshing spaces regularly instead of waiting for full turnover
These actions reduce downtime, improve tenant experience, and protect long-term value. Our Services & Small Projects division is built specifically to help owners manage these transitions efficiently and keep buildings performing between tenants.
A Practical Approach for Columbus Landlords
In Central Ohio, landlords compete not only on location and rent but on readiness. Clear definitions, realistic scopes, and proactive care create better outcomes for both owners and tenants.
Whether a space needs gray shell preparation, a white box refresh, or targeted tenant improvements, the work benefits from thoughtful planning and reliable execution.
Which Option Will You Choose?
Shell buildings, white box, and tenant improvements serve different purposes. Knowing when to use each helps landlords make informed decisions, manage budgets, and keep properties performing well between leases.
For many Columbus property owners, the most effective strategy includes both initial build-out decisions and ongoing small projects that keep spaces functional and appealing over time.
A short walkthrough can often reveal which approach fits a specific building best.
