One of the first questions business owners ask when planning a commercial renovation is:
“How much will it cost?”
It is a reasonable question, but there is no single price for commercial renovation in Lagos. A small office requiring new flooring, painting and lighting is completely different from a corporate office requiring new partitions, electrical installations, plumbing, ceilings, air-conditioning coordination, custom joinery and premium finishes. That is why two commercial renovation projects with similar floor areas can have completely different budgets. The more useful question is not simply “What is the cost per square metre?”
It is:
“What does my project require, what standard do I want, and what will it take to deliver it properly?”
This guide explains the major factors that determine commercial renovation costs in Lagos, what should be included in a proper quotation, why renovation prices can differ significantly between contractors and how to establish a realistic project budget.
Is There a Fixed Cost for Commercial Renovation in Lagos?
No.!
Commercial renovation costs depend on the specific property, scope and specification. Current office fit-out benchmarks published in 2026 also show a wide spread between low-, medium- and high-specification projects, reinforcing why a single rate per square metre can be misleading when the scope and specification are not defined. For example, consider two 300 m² commercial spaces.
Project A
The client wants:
Painting, Minor repairs, New flooring, Basic lighting, Limited electrical modifications
Project B
The client wants:
Demolition, New partitions, Reception area, Executive offices, Meeting rooms, New ceilings, Premium flooring, Electrical rewiring, Data and power points, Plumbing modification, Air-conditioning coordination, Custom cabinetry, Feature walls, Premium lighting, High-end finishes
Both projects are 300 m².
They should not cost the same.
Floor area is only one part of the cost calculation.
What Determines the Cost of Commercial Renovation?
Several factors influence the final project cost.
1. Existing Condition of the Building
The condition of the existing property is one of the first things that needs to be assessed. A building in relatively good condition may only require refurbishment and upgrading. An older property may require much more extensive work.
This could include:
Removal of old finishes, Demolition, Wall repairs, Floor repairs, Ceiling replacement, Electrical upgrades, Plumbing repairs, Water damage repairs, Replacement of doors and windows, Structural modifications where required
The more work required to bring the existing building to the desired standard, the greater the renovation budget is likely to be. This is one reason a proper site inspection should come before a final commercial renovation quotation.
2. The Size of the Property
The size of the space obviously affects the total amount of work required. However, size alone does not determine the budget. A 500 m² open warehouse may require relatively limited interior work. A 500 m² corporate office could require extensive:
Partitioning, Joinery, Lighting, Electrical installations, Air-conditioning, Data infrastructure, Flooring, Ceiling systems, Meeting rooms, Reception areas, Executive spaces
Therefore, commercial renovation should not be priced simply by multiplying the floor area by a generic rate.
3. The Scope of Work
The scope is one of the biggest cost drivers. A commercial renovation may involve only selected areas or a complete transformation of the property.
Typical work categories include:
Building Works
Demolition, Blockwork, Plastering, Screeding, Repairs, Partitioning, Structural alterations where required
Finishes
Flooring, Wall finishes, Painting, Ceiling, Doors, Windows, Feature walls
Electrical Works
Lighting, Power points, Distribution, Cabling, Switches, Electrical accessories, Data and communication provisions where required
Plumbing
Water supply, Drainage, Sanitary fittings, Kitchen or pantry plumbing, Toilet upgrades
Interior Fit-Out
Reception desks, Cabinetry, Storage, Workstations, Meeting rooms, Executive offices, Feature installations
The more categories included in the project, the more comprehensive the budget needs to be.
4. Quality of Materials and Finishes
Materials can significantly change the cost of a renovation.
For example, flooring can range from relatively economical commercial options to premium imported materials.
The same applies to:
Doors, Sanitary fittings, Light fittings, Ceiling systems, Glass partitions, Wall finishes, Cabinetry, Worktops, Paint, Hardware, Electrical accessories
A client may therefore receive two quotations for the same property that look very different simply because the contractors have priced different material specifications. This is why a quotation should identify important materials and specifications instead of simply stating:
“Supply and install flooring.”
A better quotation should make it clear what flooring is being priced.
5. Electrical and Mechanical Services
Mechanical, electrical and plumbing works — often referred to as MEP — can represent a significant part of a commercial renovation budget. This becomes particularly important when an existing building needs substantial upgrades. Depending on the project, MEP requirements may include:
Electrical distribution, Lighting, Power, Data infrastructure, Plumbing, Drainage, Air-conditioning, Ventilation, Fire-related systems, Other building services
These systems should be considered during the design and planning stage. Trying to make major changes after finishes have already been installed can create unnecessary additional cost.
6. Design and Technical Requirements
Some commercial renovation projects require relatively simple design development. Others require detailed technical documentation. Depending on the project, this may include:
Architectural drawings, Space planning, Electrical layouts, Plumbing layouts, Ceiling layouts, Joinery drawings, Interior design, 3D visualisation, Technical detailing
Design is not simply an additional aesthetic expense. Good design helps establish what is actually being constructed. That makes the project easier to price, procure and execute.
7. Custom Joinery and Built-In Elements
Custom joinery can have a significant effect on commercial renovation costs. Examples include:
Reception desks, Executive office cabinetry, Storage systems, Kitchenettes, Boardroom cabinetry, Display units, Feature walls, Built-in shelving
A commercial space with extensive bespoke joinery will naturally have a different budget from a basic refurbishment using standard off-the-shelf products
8. Location, Access and Site Conditions
The location of the project can also affect project costs. Considerations may include:
Site accessibility, Security requirements, Parking, Loading and unloading, Material storage, Building management rules, Working-hour restrictions, Lift access, Noise restrictions, Waste evacuation, Existing occupants
A commercial project inside a managed office building may have different logistical requirements from a standalone commercial property. These factors should be identified before final pricing.
9. Programme and Project Duration
Time can also affect cost. A project with a flexible programme may allow more efficient procurement and scheduling. A client requiring an accelerated programme may face additional costs associated with:
Expedited procurement, Additional labour, Extended working hours, Additional site supervision, Accelerated logistics
This does not mean that every fast project must cost more. It means that programme requirements should be understood before the project is priced.
Why Commercial Renovation Prices Change
Construction prices are not static. Material prices, exchange rates, transportation, labour and supplier pricing can change over time. This is particularly relevant where a project contains imported materials or equipment. Consequently, a quotation prepared several months ago may not necessarily remain valid indefinitely. This is why professional quotations should include a clear validity period. It also helps both the client and contractor understand the conditions under which the quoted price applies.
What Should Be Included in a Commercial Renovation Quotation?
A proper commercial renovation quotation should provide enough information for the client to understand what they are paying for. Depending on the project, it should clearly identify:
Scope of Work
What exactly will be constructed, renovated or installed?
Quantities
How much material or work is required?
Unit Rates
What is the rate for each measured item?
Materials and Specifications
What quality, brand or specification is being allowed for?
Labour
What installation or construction labour is included?
Project Management
How will the project be supervised and coordinated?
Professional Services
Where applicable, are architectural, engineering, design or other professional services included?
Logistics
Are transportation, delivery, handling or evacuation costs included?
Taxes
Are applicable taxes included?
Exclusions
What is specifically not included?
Payment Terms
When are payments due?
Programme
What is the expected project duration?
Validity
How long does the quotation remain valid?
A detailed quotation gives the client a much better basis for making a decision.
Why You Should Not Compare Commercial Renovation Quotes by Total Price Alone
Suppose Contractor A quotes:
₦40 million and Contractor B quotes: ₦32 million. It may look obvious that Contractor B is cheaper. But what if Contractor B has excluded:
Electrical upgrades, Air-conditioning, Joinery, Certain finishes, Project management, Waste evacuation, Design development
The comparison is no longer ₦40 million versus ₦32 million. You are comparing different scopes. The correct approach is to compare:
Scope → Quantities → Specifications → Exclusions → Programme → Payment Terms → Total Cost
before deciding which quotation represents better value.
What Is a BOQ and Why Does It Matter?
A Bill of Quantities, or BOQ, breaks the project into measurable work items. Instead of simply stating: “Commercial renovation — ₦50 million”
A detailed BOQ can separate the work into categories and individual items.
For example:
Demolition, Masonry, Flooring, Ceiling, Painting, Doors, Electrical, Plumbing, Air-conditioning, Joinery, Fixtures, Labour, Preliminaries, Other project costs
This creates greater visibility into how the project cost has been developed. For larger or more complex commercial projects, this level of cost documentation becomes particularly important.
Should You Budget for Contingency?
A commercial renovation budget should also account for the possibility of unforeseen conditions. This is especially relevant when renovating an older building. Once walls, ceilings or existing installations are opened up, conditions may be discovered that were not visible during the initial inspection.
Examples can include:
Hidden water damage, Damaged wiring, Deteriorated plumbing, Poor previous workmanship, Unexpected structural conditions, Concealed services
The appropriate contingency depends on the project and should be considered as part of the overall financial planning rather than treated as an excuse for uncontrolled variations.
How to Reduce Commercial Renovation Costs Without Sacrificing Quality
Reducing cost does not necessarily mean choosing the cheapest materials. Better cost control usually comes from making better decisions earlier.
1. Define the Scope Before Construction
Unclear scope creates uncertainty. The more decisions that are made before construction starts, the easier it becomes to control the budget
2. Prioritise What Matters
Not every part of a commercial property needs the same level of specification. You may choose to invest more in:
Reception, Boardroom, Customer-facing areas, Executive spaces, Collaboration areas
while using more cost-effective specifications in less visible areas.
3. Avoid Unnecessary Changes During Construction
Changes after construction has started can lead to:
Additional labour, Material wastage, Programme delays, Rework, Additional procurement costs
Good planning reduces these risks.
4. Compare Equivalent Specifications
If you are comparing contractors, make sure you are comparing the same materials and scope. A cheaper alternative should be presented as an alternative — not quietly substituted into the quotation.
5. Consider Phasing
For some businesses, completing the entire property at once may not be necessary. A renovation can potentially be divided into phases based on business priorities and available capital. The right approach depends on the property and the client’s operational requirements.
Commercial Renovation Cost vs Office Fit-Out Cost
These terms are sometimes used interchangeably, but they can describe different scopes.
Commercial renovation may involve modifying an existing building, including repairs, demolition, structural changes, finishes, MEP upgrades and interior work.
Office fit-out generally focuses more specifically on turning an existing or shell space into a functional workplace.
A project can involve both.
For example, an older office may require building renovation before the interior fit-out can be completed.
Understanding this distinction helps when defining the scope and comparing quotations.
How OurHomeFixer Approaches Commercial Renovation Costing
At OurHomeFixer Limited, we do not believe a serious commercial renovation should be priced simply from photographs or a rough description. Our process begins with understanding the project.
1. Consultation & Site Inspection
We understand the client’s requirements and inspect the existing property.
2. Bill of Quantity / Cost / Estimate / Quote
We define the scope and develop the project cost based on the requirements and site conditions.
3. Technical Drawing / Design & Visualisation
Where required, technical drawings, design information and visualisations are developed to establish what will be delivered.
4. Precision Construction & Management
The approved project is executed with coordination of the required trades, materials and site activities.
5. Quality Audit & Turnkey Handover
The completed works are inspected, outstanding issues are addressed and the project is prepared for handover. The objective is simple:
Give the client greater clarity before committing significant capital to the project.
How to Get an Accurate Commercial Renovation Cost
If you are planning a commercial renovation in Lagos, the best starting point is not a generic price-per-square-metre calculator.
Start with:
Define what you want the space to achieve.
Identify the property and its current condition.
Arrange a site inspection.
Establish the renovation scope.
Develop the required design and technical information.
Prepare a detailed BOQ or cost estimate.
Compare quotations based on equivalent scope and specifications.
Confirm the contract, payment structure and programme before construction begins.
Once these elements are defined, the project budget becomes much more meaningful.
Final Thoughts: What Should You Budget for Commercial Renovation?
There is no single commercial renovation price that can responsibly be applied to every property in Lagos.
The final cost depends on:
Property size, Existing condition, Scope, Materials, Finishes, Electrical requirement, Plumbing, Mechanical services, Joinery, Design requirements, Labour, Logistics, Programme, Site conditions
The most reliable way to establish a commercial renovation budget is therefore to define the project before trying to price it.
A realistic budget is not simply a number. It is the financial expression of a clearly defined scope.
