If you buy a new-build property or plan to renovate a home in the Netherlands, you may need a bouwdepot.
A bouwdepot is usually described in English as a construction deposit, construction deposit account, building deposit or sometimes building fund.
It is a separate account linked to your mortgage that holds money specifically intended for construction, renovation or approved energy-saving improvements.
Instead of receiving the renovation budget directly into your normal bank account, the mortgage lender keeps the money in the construction deposit.
As work progresses, invoices are paid from the depot.
For expats, understanding a bouwdepot is particularly important because it affects how much you borrow, your monthly mortgage costs, your property valuation and the amount of cash you need when purchasing the home.
What Is a Bouwdepot?
A bouwdepot is a dedicated account connected to a mortgage.
Part of your mortgage is placed into this account and reserved for approved construction or renovation costs.
The lender does this because the amount borrowed is partly based on improvements that have not yet been completed.
By controlling the construction budget, the lender can verify that the money is actually used to improve or build the property.
A construction deposit is commonly used for:
Buying a new-build home
Renovating a recently purchased property
Renovating your current home
Extending a property
Improving energy efficiency
Major structural improvements
How Does a Construction Deposit Work?
Imagine that you buy a property that requires €50,000 in renovation work.
You agree the renovation plan with your mortgage advisor and the property is valued.
The valuation can include:
Current market value
Planned renovation work
Expected market value after renovation
If the mortgage application is approved, the renovation budget can be placed into a bouwdepot.
When the contractor sends an invoice, you submit it to the mortgage lender.
After approval, the lender pays the invoice from the deposit or reimburses you if you have already paid an eligible expense.
The amount remaining in the deposit gradually decreases as the renovation progresses.
Bouwdepot for a New-Build Property
A construction deposit is a standard part of many new-build mortgage structures.
You do not pay the entire construction price to the developer on day one.
Instead, payments are normally made in stages as construction progresses.
The process can look like this:
You sign the purchase and construction agreement.
You arrange the mortgage.
The mortgage deed is signed.
The cost of the land and any completed construction stages are paid.
The remaining construction budget is placed into the bouwdepot.
The developer issues invoices for construction instalments.
Those invoices are paid from the construction deposit.
The depot becomes smaller as the home is completed.
New-build financing can also involve bouwrente, which is a different concept.
Read our separate guide explaining bouwrente when buying a new-build property.
Bouwdepot for Renovating an Existing Home
You can also use a construction deposit when purchasing an existing property that requires renovation.
For example, you may want to finance:
A new kitchen
Bathroom renovation
A roof replacement
An extension
A dormer
Insulation
New windows
Structural repairs
Heating improvements
Other permanent improvements
The lender normally wants these improvements included in the valuation and renovation specification before approving the mortgage.
This is why renovation financing should ideally be discussed before the final mortgage offer is issued.
Once the mortgage has been finalised, adding additional renovation financing can be more complicated.
Can You Add Renovation Costs to Your Mortgage?
Potentially, yes.
Whether the costs can be financed depends on several factors, including:
Your maximum borrowing capacity
The property’s current value
The property’s expected value after renovation
The renovation budget
The lender’s mortgage criteria
The type of work
Your available savings
The lender does not automatically finance every euro you spend on renovation.
For example, spending €50,000 on improvements does not guarantee that the property’s market value will increase by €50,000.
The valuation after renovation is therefore important.

Can Expats Get a Bouwdepot?
Yes.
A bouwdepot is not limited to Dutch citizens.
An expat who qualifies for a Dutch mortgage can generally also use renovation or construction financing, subject to the lender’s conditions.
The lender still assesses your overall mortgage application.
Relevant factors can include:
Residence status
Employment contract
Gross income
Foreign income
Currency of income
Existing debts
Available savings
Property value
Renovation plan
Different lenders can assess international applicants differently.
This is one reason independent mortgage comparison can be especially useful for expats.
What Can You Pay from a Bouwdepot?
Eligible expenses normally need to relate directly to the construction, improvement, maintenance or energy efficiency of the property.
Typical examples include:
Contractor invoices
Building materials
Structural work
Kitchen installation
Bathroom renovation
Roof work
Insulation
Permanent heating systems
Windows and frames
Extensions
Dormers
Electrical work
Plumbing
Approved energy-saving measures
Your lender decides which expenses qualify.
What Can You Usually Not Pay from a Bouwdepot?
A construction deposit is not a general-purpose bank account.
Items that are not permanently connected to the property may not qualify.
Depending on the lender, examples can include:
Freestanding furniture
Televisions
Decorative accessories
Moving expenses
General household items
Cars
Holidays
Unrelated personal expenses
The difference is usually whether the expenditure forms part of the approved property renovation.
Always check the lender’s rules before purchasing something you expect to declare.
Do You Need Invoices?
Yes.
The lender normally requires evidence showing how the construction money is being used.
You may need to submit:
Contractor invoices
Supplier invoices
Receipts
Proof of payment
Renovation specifications
Updated documentation where required
Keep your administration organised throughout the project.
This is especially important for tax purposes as well.
Do You Pay Mortgage Interest on a Bouwdepot?
The construction deposit is part of your mortgage financing.
You therefore pay mortgage interest according to the structure of your loan.
At the same time, lenders commonly provide interest compensation on money that is still sitting in the construction deposit.
The exact interest arrangement differs by lender.
As more money is withdrawn from the depot, the unused balance decreases.
That means the interest compensation on the remaining depot balance also decreases.
Your effective housing costs can therefore increase gradually as construction progresses.
Example of a Construction Deposit
Suppose:
Total mortgage: €450,000
Construction deposit: €50,000
€400,000 is immediately used for the purchase
€50,000 remains in the bouwdepot
At the beginning, you pay mortgage costs based on the mortgage agreement while receiving the applicable interest compensation on the money still held in the construction account.
You then use €15,000 for the kitchen.
The remaining deposit becomes €35,000.
Later, you use:
€10,000 for insulation
€15,000 for the bathroom
€10,000 for other approved renovation work
Once the full €50,000 has been used, the construction deposit is empty.
How Long Does a Bouwdepot Last?
The duration depends on the lender and type of construction deposit.
Many depots are designed around the expected renovation or construction period and can remain available for a limited period.
Two years is a common maximum period for many mortgage products, although lender-specific conditions can differ.
This should not be confused with the tax two-year rules, which have their own requirements.
If your project is delayed, contact the lender before the depot expires.
Some lenders may permit an extension under certain conditions.
Tax Rules for a New-Build Construction Deposit
Dutch tax rules contain a specific two-year arrangement for qualifying new-build deposits.
Generally, when the loan qualifies as own-home debt, mortgage interest can remain deductible for a maximum period under the applicable construction-deposit rules while the money is genuinely reserved for the new home.
Interest received on the depot affects the amount of mortgage interest that can ultimately be deducted.
The starting date and precise calculation depend on the timing of the purchase and construction agreement and the mortgage.
Because tax treatment can be situation-specific, always verify the current rules for your own case.
Tax Rules for a Renovation Deposit
A renovation construction deposit has slightly different tax treatment.
During the applicable two-year period, the relationship between:
Mortgage interest paid
Interest received on the depot
Amount already spent on renovation
determines the deductible amount.
The treatment during the first six months of a qualifying renovation deposit can differ from the following eighteen months.
Once the two-year period ends, unused money can have different tax treatment until it is actually used for qualifying work.
Keep all invoices and receipts proving that the money was used for renovation or improvement of your own home.
For more information about mortgage tax treatment, read our mortgage interest deduction guide.
What Happens to Money Left in the Bouwdepot?
If the renovation is completed and money remains, you normally cannot simply withdraw the unused amount for personal spending.
The lender may use the remaining balance to reduce the mortgage.
The exact process depends on your mortgage conditions.
If your project comes in significantly under budget, contact your lender or advisor before closing the construction deposit.
Can You Request a Bouwdepot Later?
Sometimes, but it is generally easier to arrange renovation financing as part of the original mortgage application.
Adding a bouwdepot to an existing mortgage can require:
A mortgage increase
A new affordability assessment
A new property valuation
Advice costs
Possibly notary costs
Approval from the existing lender
The available options depend on the mortgage and lender.
If you already know that you want to renovate after buying, include the renovation plan from the beginning.
Renovation Costs and Property Value
One common mistake is assuming that renovation cost and value increase are identical.
They are not.
Imagine spending €60,000 on a highly personalised renovation.
The appraiser may determine that the market value increases by only €40,000.
This difference can affect how much a lender is prepared to finance.
Renovation decisions should therefore consider both:
What you personally want from the home
What the work does to the market value
Energy-Saving Renovations
Energy improvements can receive special treatment under Dutch mortgage rules.
Depending on the property, annual lending rules and lender, additional borrowing possibilities may be available for qualifying energy-saving measures.
Examples can include:
Insulation
High-efficiency glazing
Heat pumps
Other qualifying energy improvements
The applicable amount depends on the current rules and the home’s energy characteristics.

Bouwdepot Versus Paying with Savings
You do not necessarily need to finance every renovation through your mortgage.
You could also use savings.
Using a bouwdepot
Potential advantages:
Preserve more of your savings
Finance major renovation work
Spread the cost through the mortgage
Potentially benefit from deductible mortgage interest when the requirements are met
Potential disadvantages:
Higher mortgage debt
Higher long-term interest costs
Lender administration
Restrictions on eligible spending
Using savings
Potential advantages:
No additional borrowing
No mortgage interest on the renovation amount
More freedom over how the money is spent
Potential disadvantages:
Lower cash reserves
Less financial flexibility
A large renovation can consume a substantial amount of savings
For many buyers, the best solution is a combination of mortgage financing and personal savings.
How Much Cash Do You Still Need?
A construction deposit does not mean you can purchase and renovate a property without savings.
You may still need personal funds for:
Purchase costs
Transfer tax where applicable
Mortgage advice
Notary expenses
Valuation
Structural inspection
Costs not covered by the mortgage
Renovation costs that do not qualify
An overbid above the supported market value
Read our full guide to the costs of buying a house in the Netherlands.
Documents You May Need for a Renovation Mortgage
Depending on the lender and property, prepare:
Renovation specification
Cost estimate
Contractor quotations
Valuation report
Expected value after renovation
Purchase agreement
Income documents
Identification documents
Evidence of savings
Mortgage application documents
Preparing the renovation budget early can prevent delays after your offer has been accepted.
Frequently Asked Questions About a Bouwdepot
What is bouwdepot in English?
Bouwdepot is commonly translated as construction deposit, construction deposit account, building deposit or building fund.
Is a bouwdepot part of the mortgage?
Yes. The money in the construction deposit normally comes from mortgage financing and is reserved for approved construction or renovation costs.
Can I use a bouwdepot for a kitchen?
A permanently installed kitchen can usually form part of an approved renovation budget, subject to the lender’s conditions.
Can I buy furniture with a bouwdepot?
Freestanding furniture and other movable household items generally do not qualify as construction expenses.
Can expats use a construction deposit?
Yes, provided they qualify for the mortgage and meet the lender’s criteria.
How long does a bouwdepot last?
The exact duration depends on the lender. Many mortgage construction deposits run for a limited period, commonly up to around two years.
Do I pay interest on money still in the construction deposit?
The construction deposit forms part of your mortgage. You pay mortgage interest according to the loan agreement, while the lender may provide interest compensation on unused funds in the depot.
What happens if money is left over?
Unused money is normally used to reduce the mortgage rather than being released for unrelated personal spending.
Can I arrange a bouwdepot after buying my home?
Potentially. This may require increasing or modifying your mortgage and undergoing a new affordability and property-value assessment.
Is a bouwdepot tax deductible?
The deposit itself is not simply a deduction. Mortgage interest and financing costs can qualify for tax relief when the relevant own-home and construction-deposit requirements are met.
