You are working abroad. You have been saving for years. You have found land in Nigeria, or you already own a plot that has been sitting empty. Now you want to build.
Perhaps it is a house for your parents. Perhaps you want a family home you can return to. Perhaps you are building rental apartments, or completing the house your father started.
You call someone in Nigeria. They tell you they know a good contractor. The contractor asks for money to clear the land, buy blocks and begin the foundation. You want progress, so you send it.
Three months later you have received dozens of photographs, several requests for additional money, and different explanations from the people supposedly supervising the site. You still cannot confidently answer one question:
What exactly has my money completed?
That is the question this guide is built around. You do not have to abandon a job in London, fly home from Toronto or relocate from Dubai to build a house in Nigeria. You do need a construction plan that says what happens before work starts, what happens at every stage, and what must be confirmed before the next payment is made.
Building remotely is three jobs at once.
Prepare the property. Verify the land, investigate the site, prepare professional drawings, estimate costs and obtain the required approvals.
Execute the construction. Appoint a contractor who matches the project, procure materials, manage workers, inspect completed stages and resolve problems.
Control the information and the money. The person funding the project should be able to understand what happened without depending entirely on the person asking for the next payment.
You need all three. A contractor can be experienced and still be working from incomplete drawings. Land documents can be genuine while the soil requires a much more expensive foundation than you expected. A building can look impressive in photographs while concealed structural work has not received the necessary professional checks. A completed foundation does not automatically mean the contractor should be paid for roofing.
The project needs an agreed sequence. Digital monitoring can make that sequence visible. It does not eliminate construction risk, and it does not replace a qualified engineer, architect, quantity surveyor, independent inspector or statutory authority.
There are two separate questions before you build.
Do you have a legally defensible interest in this exact land?
And: is this particular site suitable for the building you want to construct?
They are not the same question.
Do not rely on the seller's photographs, an estate brochure, or a Certificate of Occupancy sent through WhatsApp. Before a substantial payment, obtain the property documents and appoint an independent property lawyer and a registered surveyor.
Your lawyer should investigate the seller's authority, the root and chain of title, the applicable government land records, and any relevant encumbrances or disputes. Your surveyor should independently identify the physical parcel and confirm that the survey information corresponds with the land being offered to you.
How to verify land in Nigeria from abroad without coming home
Do not assume that a purchase receipt or an old deed means every acquisition requirement has been completed. Ask your lawyer to establish the current status of your title and whether any consent, stamping, registration or other perfection requirements remain outstanding. Then ask your surveyor to establish the exact boundaries before the architect develops the design.
A building that extends into a neighbour's property or a restricted area creates a problem that no architectural drawing will solve.
Two plots in the same neighbourhood can require different construction methods. One may suit the proposed building. Another may be filled, waterlogged, or affected by poor drainage, erosion or difficult access. You cannot choose a foundation by looking at the house next door.
Before the structural design is finalised, the relevant professionals should investigate the site. Useful questions include:
Your structural engineer and geotechnical professional should decide which investigations fit this building and this site.
Ask for a dated site-assessment report, survey information, relevant geotechnical findings, and a written explanation of how those findings influence the design. If the structural engineer recommends a particular foundation system, you should understand what information informed that recommendation.
Do not accept “the foundation everybody uses around here is strong enough.” The foundation is supporting your specific building on your specific land.
Before you ask a contractor how much a duplex will cost, answer a more useful question: what must this property achieve?
A family home, a rental building and a retirement property have different requirements. If you are building for your parents, access, stairs, bathrooms and long-term maintenance may matter more than luxury finishes. If you are building rental apartments, design and materials should respond to the intended tenants, local demand, maintenance costs and the property's financial purpose. If you are building your future home, consider how the household might use the building over time.
Give the architect a written brief: intended use, room requirements, finish preferences, budget direction, and any accessibility or utility requirements. Then set a financial limit. Do not confuse current savings with the full amount the project will need. You may have enough money to start a five-bedroom duplex and not enough to finish it.
The objective is not an impressive foundation photograph. It is a building that can reach an agreed, useful completion point.
An attractive 3D rendering is not a complete set of construction instructions. Before major construction begins, the project needs the appropriate professional design information. Depending on the building, that may include architectural drawings, structural calculations and drawings, electrical layouts, plumbing and drainage layouts, roof details, and schedules of relevant building elements.
Those documents have to work together. If the architect has positioned a bathroom above the sitting room, the structural and plumbing information must account for how that space will be supported and drained. If you plan air conditioning, an inverter, solar panels or substantial water storage, the relevant professionals should consider those requirements during design rather than leaving them for artisans to improvise later.
Use appropriately qualified professionals for the relevant work. For engineering services, you can independently check a practitioner's or firm's registration on the official COREN registration-verification portal.
COREN registration verification
A contractor's portfolio does not replace the design professionals. Once the drawings are ready, obtain a coordinated package with revision numbers and dates. If the drawings change during construction, everybody should know which version is approved for execution.
A Bill of Quantities, or BOQ, translates the drawings and specifications into measurable work items. Instead of “how much to build a four-bedroom duplex?”, you can ask how much the excavation, foundation, concrete, reinforcement, blockwork, roofing, electrical installation, plumbing and finishes in this specific design require.
A quantity surveyor can prepare cost information and examine contractor quotations against the defined design and scope. The BOQ should be detailed enough to show what is included and what is excluded.
The full financial plan may also need land-related expenses, professional fees, site investigations, approvals, statutory charges, utility connections, external drainage, supervision, logistics, security and contingency. The exact items depend on the project. A contractor's quotation is only as complete as the scope it covers.
BuildMyHouse has a Price Checker that helps homeowners research Nigerian building-material prices using available source evidence, specifications and a confidence assessment. Use it when a contractor sends a material quotation and you want to see whether the listed prices sit near available market information.
A general online price is not a guaranteed delivered cost for your site. Specification, quantities, supplier terms, transport, location and purchase timing still matter. For major procurement, obtain current written quotations for the actual materials the project requires. Prices shown in the Price Checker are research aids, not BuildMyHouse estimates of what your site will pay.
Buying land does not authorise you to build whatever you want on it. Planning and building-control requirements depend on the state, the location and the project.
If the property is in Lagos, understand the roles of the Lagos State Physical Planning Permit Authority (LASPPPA) and the Lagos State Building Control Agency (LASBCA). Lagos building control includes the planning-permit stage, authorisation to commence construction, and inspections at relevant construction stages. LASBCA also provides for completion and fitness-for-habitation certification.
This is not a step to ignore until an enforcement officer arrives. Before workers begin the relevant activity, establish which approvals and notices are required and who is responsible for obtaining them.
Lagos building permits and stage inspections guide
For projects outside Lagos, confirm the requirements with the appropriate state planning and building-control authorities.
BuildMyHouse's private project monitoring does not replace inspections, authorisations or certifications required by government authorities. Both processes belong in the project plan.
A contractor who renovated three bathrooms is not automatically equipped to execute a multi-storey residential building. The contractor should match the complexity, value, location and technical requirements of the proposed project.
Review identity, business information, relevant professional credentials, previous work, references, current capacity and the proposed execution team. Ask for evidence of completed projects comparable to yours. If a contractor claims to have built a particular property, obtain permission and check the claim independently. Also find out who will actually supervise the site. The person who negotiated with you may not be the person supervising reinforcement or concrete.
BuildMyHouse uses contractor onboarding and document review rather than an informal introduction alone. Contractors can submit identity, business, professional and supporting documents for review. That review is not a guarantee that every future decision or piece of work will be correct. Contractor checks sit alongside project documentation, stage visibility, homeowner approval, and technical review where the scope requires it.
When the drawings, scope and budget are ready and the contractor has been assessed, the agreement has to explain how work and payments proceed. A useful construction agreement defines the work, applicable drawings, specifications, programme, stage breakdown, price, mobilisation requirements, completion criteria, variations, defects, responsibilities and the dispute procedure. Do not wait until you disagree about workmanship to discover that nobody defined completion.
The aim is to fund approved work without asking the contractor to finance the homeowner's project, and without asking the homeowner to release an entire stage with no accountability.
Depending on the agreed stage, the contractor may receive an initial mobilisation payment for approved materials, labour and other commencement costs. The contractor executes the stage and submits the required evidence. Where technical verification is required, the appropriate independent professional or testing process should be carried out. The homeowner reviews the stage information and confirms whether the agreed work is satisfactory. Once the applicable checks and approval conditions are met, the contractor is paid the agreed balance. The next stage can then receive its approved mobilisation when it is ready to begin.
This is a private project-payment workflow. It is not a regulated bank escrow, and it is not a guarantee that money can always be recovered after it has been disbursed. The payment, custody, refund and dispute terms should be clear before you fund a project.
Suppose a stage has an agreed value of ₦10,000,000. For illustration only, the parties agree ₦3,000,000 mobilisation, with the remaining ₦7,000,000 tied to accepted completion of that stage. The contractor uses the mobilisation for the approved commencement requirements. After the work is completed and the required checks and homeowner approval are satisfied, the outstanding stage payment is released. The next stage is considered separately.
That split is an illustration, not a fixed percentage for every BuildMyHouse project. You can draft your own initial stage plan with the Milestone Payment Schedule Builder.
One of the most expensive construction mistakes is covering a defect that should have been found earlier. Imagine major cracks through the walls. The contractor says the plaster will hide them. The cracks could relate to foundation movement, poor masonry, inadequate support, defective materials or another structural issue. The response is not a WhatsApp diagnosis. A qualified professional should investigate the cause and determine the corrective action. If serious structural failure is confirmed, the engineer may recommend rebuilding an affected section or another properly designed remedy.
Before a foundation is covered by later work, the relevant professional and statutory inspection requirements should be addressed. Depending on the design and stage, the evidence may include inspection reports, site observations, measurements, approved drawings, test results and records of corrective work. LASBCA describes stage inspections and certification as part of building control in Lagos.
A BuildMyHouse homeowner should be able to see which inspection was required, whether it was carried out, what the result was, and whether an unresolved issue stops the next stage. Photographs of a completed foundation are progress evidence. They are not, by themselves, a structural certification. Homeowner approval of a stage does not replace the engineer's technical judgment or a statutory stage inspection.
The sequence below is illustrative. Your actual stages and acceptance criteria must follow the approved design, the contract and the professional requirements.
You do not have to understand every technical calculation. You should know which stage you are paying for, which professional is responsible for checking it, and what information confirms that the stage can move forward. A stage that is unfinished, defective or waiting on a required technical decision should not be treated as fully accepted because the contractor has requested more money.
A brother near the site, a father who visits at weekends, or a family friend who understands construction can be valuable. Being able to visit the site does not mean that person can assess a structural foundation, reconcile a BOQ, or decide whether electrical work meets the relevant requirements.
Give family members a clear role: access, scheduled visits, household needs, or an independent observation of whether work is happening. Technical and financial decisions stay with the appropriate professionals and the agreed project process. It should also be clear who can request changes, approve additional spending and accept completed work. A suggestion made during a family visit can otherwise become an expensive variation nobody authorised.
Five photographs of blocks and workers do not tell you much unless they are tied to a defined stage and an explanation of the work. A useful update answers:
The weekly site update standard for diaspora homeowners
You can preview the monitoring experience in the BuildMyHouse project-monitoring demo. The aim is updates that are useful enough for a decision without travelling home every time somebody asks for money.
No responsible manager should promise that a complex building will never change. Site conditions, technical findings, client decisions and material availability can all affect the original plan. Change should still be documented.
If an approved detail cannot be executed as planned, you should receive an explanation, supporting evidence, the recommended solution, any alternatives, the cost change and the effect on the programme. The relevant professional should review changes that involve technical design or safety. The homeowner should understand and approve the applicable change before it becomes an additional financial commitment.
BuildMyHouse's project structure is meant to record stage changes and disputes, rather than leaving every new request in a WhatsApp thread. Contingency is controlled money for justified uncertainty. It is not a standing invitation to spend whatever is left.
Perhaps the building has stopped at lintel level. Perhaps the contractor has left. Perhaps you have noticed serious cracks, or the drawings no longer match what was built. Do not automatically send another payment to restart work.
First establish what exists. For an abandoned or seriously disputed project, commission an independent assessment of the physical work, relevant structural condition, remaining scope, available materials and project records. If a potentially serious structural defect is present, restrict unsafe activity and obtain a prompt professional assessment before further construction. Then set a revised scope, a cost-to-complete estimate, a programme and a contractor arrangement.
How to finish an abandoned house in Nigeria from abroad
The aim is not merely to restart work. It is to understand why the first attempt stopped, and what must change before more money is committed.
The approach is to connect the homeowner, the contractor, the scope, the evidence and the payment decisions in one structured process. The homeowner starts by describing the property work, its location and the information already available. BuildMyHouse then helps organise the relevant contractor and project-management workflow.
As work progresses, the homeowner can follow stages, review submitted evidence, see project information and communicate through the platform. Where the scope requires a professional or statutory inspection, those requirements stay in the project. Photographs do not replace them. The agreed approval process then determines when the contractor is paid and whether the project is ready for the next stage.
In June 2026, BuildMyHouse coordinated a plumbing repair at a homeowner's property in Mowe, Ogun State. The contractor first suggested a price remotely. BuildMyHouse required a physical inspection before the final scope was approved. After inspection, the contractor submitted a ₦66,000 quotation. Following negotiation, the contractor agreed ₦55,000. The homeowner's total payment was ₦60,500, including BuildMyHouse's monitoring and coordination fees. The contractor received ₦30,000 for the approved initial requirements. After the repair, material evidence and completion media were reviewed, and the homeowner confirmed she was satisfied. Only then was the outstanding ₦25,000 released. The inspection and the repair were completed the same day.
That was a small plumbing job, not a full house. It is not evidence that every technical challenge of a large building has already been solved. It does show the operating principle: understand the problem, agree the work, fund the required activity, document completion, obtain homeowner approval, then pay the contractor. The same discipline matters more when the work is a foundation, a roof, a renovation or a new building.
You do not have to begin by handing over a multimillion-naira construction project. A repair at your parents' home, a site inspection, a material-price check, or a construction payment schedule are all ways to learn the process.
The BuildMyHouse homepage currently describes a first-project offer for qualifying projects: ₦0 BuildMyHouse platform commission, a free first inspection, and access to homeowner tools. That offer is not a universal promise for every full-build contract. Eligibility and terms can change.
