Building Advice & Drawing Office Rotterdam
Aboss supports projects in Rotterdam with permit applications, architectural drawings and structural calculations. Fast, technically substantiated and practical for both municipality review and construction.
An extension, dormer, roof build-up or structural intervention requires more than a rough sketch. We produce drawing packages and technical dossiers that are logical for permit review, workable on site, and designed to reduce delay and rejection risk.
Local context: technical dossiers aligned with Rotterdam permit practice.
What we provide
We deliver building-related drawing work in every phase of the process, from initial design through permit application and execution.
Permit documentation
Application drawings, site plans, sections, elevations and full packages for environmental permit submissions.
Structural substantiation
Structural calculations, structural drawings and technical details for safe and reviewable interventions.
The building permit is now part of the environmental permit system
Since the introduction of the Wabo and later the Omgevingswet, several permit types have been brought together under one framework: the environmental permit. This includes categories that were formerly known as building permit, demolition permit, tree-cutting permit, works permit and monument permit.
In practice this means your submission must be technically, architecturally and administratively consistent. As soon as documents are missing or unclear, the municipality can suspend the decision period or leave the application unprocessed.
How long does a permit application take?
Regular procedure
The regular procedure usually takes up to 8 weeks. In some cases, the municipality may extend this once by 6 weeks.
Extended procedure
More complex applications, such as those involving planning deviations or monument-related works, often fall under a longer procedure.
If the application is incomplete, the decision period is suspended until the missing documents are supplied. That is why a technically complete dossier from the start is essential.

Yes. We do not only provide drawings, but also advice, structural substantiation and the technical documents needed for the permit application.

Not always, but for structural interventions, openings, extensions, roof build-ups or other load-bearing changes it is often necessary.

Yes. We also prepare sales drawings, presentation drawings and digitally redrawn plans for existing homes.
What do you need to get started?
