Request Construction Drawings: How to Find the Original Plans of Your Home

Planning a renovation, submitting a permit application, or buying a property: in all these situations the original construction drawings of the building are indispensable. They provide insight into the structure, the location of load-bearing walls, and the dimensions of spaces. Yet many people do not know how to obtain those drawings or what to do when the archive comes up empty.

This article explains the full process: why you need the drawings, where to request them, what it costs, and what to do when they no longer exist.

Why do you need the original construction drawings?

Original construction drawings contain the crucial information that defines a property: floor plans per floor with exact dimensions, elevation views, cross-sections showing the structural build-up, and details about foundations or floor beams. Without that information you are working on assumptions, and assumptions always cost money in construction and renovation.

The most common situations in which you need the drawings:

Renovation or extension. A contractor or drafting firm uses the existing situation as the starting point for new plans. If you do not know where load-bearing walls are, you risk costly discoveries halfway through the renovation.

Permit application. A planning permit always requires drawings of both the existing and the new situation. Without a correct existing-situation drawing, the municipality cannot assess the application.

Purchase or sale. Drawings give potential buyers insight into the layout and structure. They also help when assessing renovation possibilities and for property split applications.

Checking earlier renovations. Want to know whether past modifications were carried out with a permit? The municipal drawings show the approved situation. Deviations from those drawings can have legal or insurance consequences.

Where do you request construction drawings?

The municipality: the most direct source

Municipalities retain permit applications and the associated drawings. This is the first place to start. Contact the Building and Housing department, or submit the request via the Omgevingsloket (omgevingsloket.nl). Many municipalities process requests digitally, meaning recent drawings are sometimes available within a few working days.

For older properties a physical archive visit is sometimes necessary. Make an appointment and bring identification and proof of ownership. Each municipality has its own rates and turnaround times, so check the municipal website in advance.

Bear in mind that municipalities are not obliged to retain drawings older than twenty years. Many do, but it is not guaranteed. Renovations carried out without a permit are also not in the archive.

The city archive

If the municipality no longer has the construction drawing, the city archive is the next step. Historical archives sometimes retain building documents for much longer than the municipality itself. This is particularly relevant for homes built before 1960. Via the city archive website you can usually enquire whether drawings are available.

The Land Registry

The Land Registry (Kadaster) manages data about real estate in the Netherlands, such as plot boundaries and ownership information. Cadastral drawings provide insight into plot boundaries and built structures, but do not typically contain full construction details. The Land Registry is useful as a supplementary source or when you need the cadastral data for your application. Read more about cadastral drawings.

The previous owner or the original drafting firm

If you know who had the property built or who carried out later renovations, direct contact is a quick solution. The original drafting firm or building company sometimes retains project files for decades. After a recent purchase it is advisable to ask the seller during the purchase process whether they have any drawings. They formally belong with the transfer of the property but are often overlooked in practice.

Step-by-step: how to request construction drawings

Step 1: Determine which drawings you need. Do you only need the floor plan, or also elevation views, cross-sections, and structural drawings? This depends on your renovation plans. For a dormer, floor plans and elevation views are standard; for an extension you often also need a cross-section and structural details. Clarifying this up front prevents you from having to submit additional requests later.

Step 2: Gather the required information. For a successful request you will need at minimum: the full address including postcode, the year of construction (findable via Funda or the Land Registry), the cadastral number, and information about known renovations. The more specific your request, the faster the archive will locate the correct documents.

Step 3: Submit the request to the municipality. Go to the municipal website and look for the request procedure for construction drawings. You can often complete a form online. Clearly state which documents you are looking for and for what purpose. A written authorisation or proof of identity may also be required.

Step 4: Wait for the response and check the result. When you receive the drawings digitally, check immediately whether they are complete and legible. A complete set includes a site plan, floor plans of all floors, all elevations, and at least one cross-section. If drawings are missing or unclear, get back in touch.

Step 5: Compare the drawings with the current situation. Walk through the property and check whether the drawings match what you see. Have rooms been added, walls removed, or windows moved? Discrepancies can mean that renovations were not permitted or that the drawings are no longer current.

Step 6: Consult alternative sources if the municipality has nothing. Try the city archive, the Land Registry, or the previous owner. If the municipality gives a negative answer, always ask for written confirmation that the file is not available. This is useful documentation if you later need to have new drawings made.

Costs and delivery times

• Municipality (digital archive): Free to 50 euros · 2 to 5 working days
• Municipality (physical archive): 75 to 250 euros · 2 to 4 weeks
• City archive: Varies, sometimes free · 1 to 3 weeks
• New drawings made: 350 to 1,500 euros · 1 to 3 weeks

Be aware of cost differences between municipalities. Larger municipalities more often have automated systems and charge less. Smaller municipalities with paper archives sometimes charge more due to manual search work. Some municipalities only charge for downloading documents, not for viewing.

Requesting a complete building dossier, including permits and calculations, is cheaper than ordering individual documents separately. Request the complete dossier right away.

What if the drawings no longer exist?

Sometimes the dossier is completely missing. This occurs with homes built before 1960, with properties that have gone through multiple municipal boundary changes, or with renovations that were never permitted. In that case there are two options.

Option 1: Have new survey drawings made. A drafting firm visits on-site, accurately surveys the property, and produces a complete set of construction drawings of the current situation. This delivers current, accurate drawings that are immediately usable for a permit application or renovation. It is admittedly the most expensive option, but it also gives the most reliable result. Past renovations are automatically captured in the drawings.

Option 2: Digitalisation of paper drawings. Do you have old paper drawings in poor condition? A drafting firm can digitalise and update these in CAD. This gives you a manageable, editable file instead of a fragile paper document.

SK Tekenwerk handles both via the archive service. After surveying the property we deliver permit-ready drawings, tailored to the requirements of the relevant municipality.

Legal considerations

Construction drawings are protected by copyright, owned by the creator, typically the drafter or drafting firm. As the owner you may use the drawings for your own project, have renovation plans drawn up on the basis of them, and submit them for a permit application. Reselling or commercial reuse is not permitted without the consent of the rights holder.

Technical copies you receive from the municipality are intended for personal use. Provide a copy to your drafting firm or contractor when they need the drawings as a reference.

Common mistakes

Starting too late. Archives need time. Municipalities sometimes only deliver after four weeks, especially for physical dossiers. Start the request well before the renovation or permit application.

Incomplete request details. A vague request such as "I am looking for the drawings of my house" costs the archive extra search time. State the address, postcode, year of construction, cadastral number, and the period of known renovations.

Requesting only the floor plan. For a permit application you also need elevation views and cross-sections. Always request the complete building dossier.

Not checking whether the dossier is complete. When you receive drawings, check whether all floors, all elevations, and the cross-sections are present. Dossiers are sometimes spread across multiple applications.

Using outdated drawings without verification. Drawings from twenty years ago may still be correct, but only if nothing has been renovated since. Always compare the drawings with the current situation before using them for a permit application.

Summary

Requesting construction drawings goes most smoothly when you know in advance which documents you need, submit the request early, and ask for the complete building dossier. The municipality is the first source, followed by the city archive, the Land Registry, and the previous owner. If no drawings are available, a new survey is the most reliable solution.
