Permit Application Help: Your Technical Shield
“If this isn’t correct, the municipality intervenes — we make sure it’s correct.”
Do you need a permit for an extension, roof build-up, or removing a load-bearing wall? Applying for a Dutch environmental permit (omgevingsvergunning) is often stressful due to bureaucracy and strict technical demands. Aboss Bouwadvies operates as your risk firewall against building stops and rejections. We turn your plans into a legally and technically unstoppable dossier.
What we deliver: a municipality-proof dossier
We do not deliver generic sketches. We deliver a technically substantiated dossier that matches the submission requirements of the Omgevingsloket — built for direct review by Building Control.
Structural calculations
Static calculations for steel, timber or concrete. Crucial for structural safety and in practice often decisive for permit review.
Bbl compliance (health & safety)
Precise calculations for daylight access, ventilation and purge ventilation capacity. We ensure your habitable space complies with the Decree on the Built Environment (Bbl) — and that compliance is provable.
Submission-ready package
Not just “documents”, but a dossier that is logically structured: complete, reviewable, and correctly categorised for Omgevingsloket submission.
Regulatory context: the power of the Omgevingswet
Since the introduction of the Dutch Environmental and Planning Act (Omgevingswet), checks against the Omgevingsplan and the Decree on the Built Environment (Bbl) have become stricter than ever. Many applications are paused as “incomplete” because technical reports are missing or incorrectly categorised.
We think like Building Control. We anticipate rejection triggers before the case officer even opens your file. We speak the regulator’s language — so you can focus on building.
Working method: from risk to permit
Our workflow is designed for maximum predictability in an uncertain process — with control over risks, completeness, and reviewability.
1) Intake & feasibility
Analysis of your plan versus the local Omgevingsplan rules (and real-world review patterns).
2) Technical dossier
Our engineers and draughtsmen produce all required documents: calculations + drawings.
3) Submission (Omgevingsloket)
We handle the full submission and act as your technical point of contact for the municipality.
4) Monitoring
Active support during the statutory timeline (typically 8 weeks) up to permit granting, including responses to technical questions.
Regional expertise: local nuance, national execution
Interpretation differs per region. Aboss understands local nuances and builds dossiers that anticipate them.
Amsterdam
Strict enforcement on foundations, heritage values, and Bbl requirements in the historic inner city.
Rotterdam
Focus on efficient apartment splitting and the structural challenges of roof build-ups (optopping).
Utrecht
Navigating aesthetics/heritage review and increased permit pressure in densified areas.
Typical projects & crisis response
Extension or roof build-up
Full application including drawings, structural file and — where relevant — the often underestimated aesthetic review. Outcome: a dossier that does not stall on incompleteness.
Legalising unpermitted works
Obtain a permit after the fact to avoid penalties, enforcement orders or demolition. We build the technical substantiation the municipality can review.
Lifting a building stop
Immediate intervention when works are stopped due to missing calculations or permit coverage. Focus: recovery plan + submission-ready dossier.
Load-bearing wall / steel portal
Structural calculation and detailing for safe execution and review. Includes temporary propping / phasing logic where needed.
FAQ: answers to critical questions
When is an environmental permit required?
In practice: almost always for structural changes (such as removing a load-bearing wall) or street-facing façade changes. If in doubt, start the permit check and avoid wrong assumptions.
How long does the procedure take?
The regular procedure takes up to 8 weeks. For complex cases, the municipality may extend once by 6 weeks. After approval, consider an objection window (typically 6 weeks) before starting “safely”.
What if my application is marked “incomplete”?
This often results from an incomplete or incorrectly categorised dossier. We diagnose the gap and add missing technical data (Bbl/structural) quickly so the process can resume.
Do not take the risk
Prevent delays and building stops. Let Aboss be your technical and legal partner. We offer a productised solution with a clear scope — so you know what to expect upfront.
If the municipality doubts — we make it correct.
