How Splitting a Large Commercial Property Into Smaller Units Can Increase Its Value

Sometimes smaller spaces create bigger opportunities

When investors acquire a large commercial building, the traditional approach is often to search for one tenant capable of occupying the entire property.

But that isn’t always the most profitable strategy.

Across many commercial property markets, particularly industrial and warehouse sectors, subdividing larger premises into smaller self-contained units can dramatically increase the number of potential occupiers.

Done correctly, subdivision can create multiple rental streams, reduce reliance on a single tenant and potentially increase the overall rental value of an asset.

At Citrus Commercial Circle, we regularly see strong demand for practical small and medium-sized commercial units across Bury, North Manchester and the wider North West.

For the right building, thinking smaller can sometimes produce a much bigger result.

What does subdividing commercial property mean?

Commercial subdivision involves taking one larger property and creating two or more independently occupiable units.

Depending on the building, this could involve creating separate:

• Entrances
• Roller shutter doors
• Electricity supplies
• Water supplies
• Toilets
• Parking areas
• Loading areas

The objective is to create units capable of functioning independently.

For example, a 20,000 sq ft industrial building might potentially be configured as four 5,000 sq ft units, subject to the physical characteristics of the building and all necessary permissions and approvals.

Smaller units can attract more businesses

One of the biggest advantages of subdivision is the potential increase in the number of prospective occupiers.

There are generally far more businesses capable of occupying a 2,000–5,000 sq ft unit than a 20,000 sq ft warehouse.

Potential occupiers could include:

• Tradespeople
• Online retailers
• Manufacturers
• Engineering businesses
• Wholesalers
• Distributors
• Storage operators
• Local service businesses

A broader tenant pool can potentially reduce letting risk.

Smaller units may achieve stronger rents per square foot

Commercial rental values do not always increase proportionally with property size.

In some markets, smaller units can command higher rents per square foot than significantly larger buildings.

Consider a simplified example.

A 20,000 sq ft warehouse might achieve £7 per sq ft if let to one occupier.

That would produce:

£140,000 per annum.

If the same property could legitimately and practically be divided into four units, and smaller units in that particular location achieved £9 per sq ft, the potential headline rent could become:

£180,000 per annum.

That represents an additional £40,000 of potential annual rental income before allowing for the costs, voids, incentives, management and other considerations associated with a multi-let strategy.

This is only an illustration rather than a valuation assumption, but it demonstrates why investors sometimes explore subdivision.

Multiple tenants can diversify income

A single-let building creates one income stream.

If that tenant leaves, the property may immediately become completely vacant.

A multi-let property spreads income across several occupiers.

If one unit becomes vacant, rent from the remaining units may continue.

This diversification can make income more resilient.

Void risk works differently

Subdivision does not eliminate vacancies.

Instead, it changes the nature of the risk.

With one large tenant, an investor may experience long periods of stable income followed by potentially significant vacancy if the tenant leaves.

With multiple smaller units, individual vacancies may occur more frequently, but they affect a smaller proportion of total income.

Understanding this difference is important when designing an investment strategy.

Separate utilities are extremely important

One of the practical challenges when dividing commercial property is utilities.

Ideally, each unit should have clearly identifiable supplies or suitable metering arrangements for services such as:

• Electricity
• Water
• Gas, where applicable

This makes occupation simpler and helps avoid disputes over consumption.

Investors should assess existing infrastructure before deciding whether subdivision is financially viable.

Access must work independently

Creating walls inside a warehouse is relatively straightforward compared with solving poor external access.

Each proposed unit needs practical arrangements for:

• Deliveries
• Customer access
• Staff access
• Emergency escape
• Waste collection
• Parking

Industrial units may also require independent loading access.

A subdivision strategy should therefore begin with the external layout as well as the internal floor plan.

Roller shutters can influence the entire design

For industrial properties, roller shutter access is particularly important.

If a large building only has one loading door, creating four independent warehouse units may require significant structural work.

Buildings already containing multiple loading doors can sometimes lend themselves particularly well to subdivision.

This is why investors should assess potential configuration before purchasing an asset.

Parking allocation needs careful planning

Parking can become more complicated when the number of occupiers increases.

One tenant may operate relatively few vehicles.

Four businesses occupying the same property could generate considerably more traffic.

Landlords therefore need to consider:

• Staff parking
• Customer parking
• Delivery vehicles
• Loading areas
• Turning space

Poor parking arrangements can quickly create problems between neighbouring occupiers.

Fire safety becomes more complicated

Changing the internal configuration of a building can affect fire safety arrangements.

Issues may include:

• Escape routes
• Fire separation
• Alarm systems
• Emergency lighting
• Fire doors
• Occupancy levels

Professional advice should therefore be obtained before undertaking subdivision works.

Information on workplace fire safety responsibilities is available from GOV.UK fire safety guidance.

Planning permission may be required

Not every subdivision project can proceed automatically.

Depending on the circumstances, investors may need to consider:

• Planning permission
• Building Regulations
• Existing planning conditions
• Use restrictions
• Listed building considerations

The Planning Portal provides useful general information about planning and Building Regulations in England, but property-specific advice should be obtained from the relevant professionals and local authority.

Business rates should be investigated

Subdivision may also affect business rates.

Where separate units are created, the rating arrangements may change depending on how the property is occupied and assessed.

The Valuation Office Agency is responsible for compiling rating lists in England and Wales.

Investors should understand the potential rating implications before completing major alterations.

Management requirements will increase

A single-let property can sometimes require relatively limited day-to-day management.

A multi-let estate may involve considerably more.

The landlord could be managing:

• Several rent accounts
• Multiple lease renewals
• More maintenance enquiries
• Shared areas
• Service charges
• Parking arrangements
• Estate security

The additional income potential therefore needs to justify the additional management burden and costs.

Security can become more important

More businesses generally mean more employees, customers, suppliers and delivery drivers accessing the property.

Investors may therefore consider improvements such as:

• CCTV
• Access-controlled gates
• External lighting
• Security barriers
• Unit numbering
• Clear estate signage

Good estate management can become an important part of tenant retention.

Service charges may be necessary

Where several tenants share common areas or services, landlords may need an appropriate service charge structure.

Shared expenditure could potentially include:

• Estate lighting
• Security
• Landscaping
• Communal repairs
• Private roads
• Drainage
• Shared facilities

The leases should clearly establish responsibilities.

Professional legal advice should always be obtained when preparing commercial lease documentation.

The cost of subdivision must be calculated carefully

Higher potential rent does not automatically mean subdivision is worthwhile.

Investors need to calculate the cost of works.

These might include:

• Partition walls
• Additional shutters
• Electrical works
• Plumbing
• Toilets
• Fire protection
• Doors and windows
• Separate meters
• External alterations
• Professional fees

The project should be considered as an investment rather than simply a construction exercise.

Look at the payback period

One useful approach is comparing the capital expenditure required against the additional rental income that could realistically be generated.

If significant investment produces only a small improvement in annual income, the project may not make commercial sense.

Conversely, where strong demand exists for smaller units and relatively modest alterations unlock substantially higher income, subdivision can become extremely attractive.

Local rental evidence is therefore crucial.

Don’t create units that are too small

There is a balance.

Creating the maximum possible number of units isn’t necessarily the best strategy.

Each unit still needs to be commercially usable.

Occupiers need sufficient:

• Workspace
• Storage
• Loading access
• Parking
• Welfare facilities

Poorly designed units may be difficult to let regardless of their size.

Flexibility can be more valuable than permanent division

Investors should also consider whether subdivision should be reversible.

Flexible partitioning and thoughtful service design may allow adjoining units to be combined again in the future.

For example, four units could potentially be marketed as:

• Four individual units
• Two larger units
• One larger unit plus two smaller units

This flexibility significantly broadens the potential occupier market.

Location determines whether the strategy works

Subdivision works best where genuine demand exists for smaller commercial premises.

Factors influencing demand include:

• Nearby motorway access
• Population density
• Local business activity
• Availability of competing units
• Rental affordability
• Established industrial locations

A strategy successful in one town may not necessarily work in another.

Local market knowledge remains essential.

North Manchester is particularly suited to SME demand

Bury and the wider North Manchester market contain a substantial number of small and medium-sized businesses requiring practical commercial accommodation.

Industrial units, workshops, trade premises and smaller warehouses can appeal to businesses that have outgrown home-based operations, containers or smaller storage facilities but are not ready for major distribution centres.

This creates an important middle market for commercial landlords.

Subdivision can create an investment estate from one building

Perhaps the most interesting aspect of subdivision is that it can transform the nature of the asset.

Instead of owning one large warehouse, an investor may effectively create a small multi-let business park.

That can introduce:

• Multiple income streams
• Staggered lease expiries
• Different rent review opportunities
• Greater tenant diversity
• Potential individual unit sales in some circumstances, subject to title, legal and planning considerations

The investment strategy becomes fundamentally different.

Professional advice should come before construction

Before beginning a subdivision project, investors may require advice from:

• Commercial property agents
• Architects
• Planning consultants
• Building surveyors
• Structural engineers
• Solicitors
• Fire safety professionals

The Royal Institution of Chartered Surveyors and Royal Town Planning Institute are useful starting points when looking for appropriately qualified property professionals.

Spending time assessing feasibility before construction begins can prevent expensive mistakes.

Citrus Commercial Circle’s market insight

At Citrus Commercial Circle, we believe one of the biggest opportunities in commercial property is identifying how an existing building could work harder.

Sometimes that means refurbishment.

Sometimes it means securing stronger tenants.

And sometimes it means reconsidering the entire configuration of the property.

Where local demand supports it, dividing a larger commercial building into well-designed smaller units can create greater flexibility, diversify income and unlock rental potential that may otherwise remain unrealised.

Final thoughts

Bigger isn’t always better in commercial property.

A large warehouse may appeal to a relatively narrow group of occupiers, while several smaller units can potentially attract a much broader range of businesses.

However, successful subdivision requires careful consideration of planning, utilities, fire safety, access, parking, construction costs and local rental demand.

When the numbers and the building work together, subdivision can become a powerful commercial property asset management strategy.

At Citrus Commercial Circle, we are proud to help landlords and investors across Bury and North Manchester identify opportunities to unlock greater potential from their commercial property assets.
