Aboss Bouwadvies: technical clarity between design, structure and permits
Aboss Bouwadvies supports private and professional clients with architectural and structural questions in the Netherlands. We combine architectural drawings, structural engineering and Dutch permit logic into technical dossiers that are clear, verifiable and usable in practice.
Our work is especially valuable when a project needs more than a visual drawing: when the municipality requests technical clarification, when a contractor needs structural information, or when an existing building must be assessed before a renovation can continue safely.
We do not replace the formal municipal decision process. We help make the technical dossier clearer, more consistent and better prepared for review.
Structural logic
Load paths, steel beams, timber structures, foundations, stability and practical execution constraints.
Permit readiness
Technical documents structured for municipal review, contractor coordination and clear decision-making.
Who we are
Aboss Bouwadvies is an Amsterdam-based technical consultancy working at the intersection of architecture, structural engineering and permit preparation. We focus on projects where clear drawings and a technically defensible basis are essential.
Typical projects include renovations, extensions, wall openings, roof extensions, floor openings, legalization cases, apartment division drawings, foundation-related questions and technical dossiers for environmental building permits in the Netherlands.
We look beyond the visible design. We consider how the plan will be reviewed, how the contractor will build it, and whether the technical assumptions match the real existing situation.
Our role in a building project
Many construction projects are delayed not because the idea is wrong, but because the technical information is incomplete, inconsistent or difficult to review. This is where our work adds value.
We structure the project information so that architectural drawings, structural reasoning and permit documents support each other instead of contradicting each other.
1. Architectural
Floor plans, sections, elevations, existing and proposed situations, measured drawings and technical details for permit applications or construction preparation.
2. Structural
Technical assessment and structural calculation for load-bearing walls, steel portals, timber beams, floor openings, roof structures, foundations and stability.
3. Permit-oriented
Dossiers prepared with municipal review in mind, including clear drawings, calculation logic and additional technical documentation when required.
Our working method
We prefer a structured process. First, we clarify the existing situation and the client’s question. Then we determine which drawings, calculations and supporting documents are required for the project’s goal: execution, permit review, legalization or technical risk control.
-
Initial review
We review the address, available drawings, photographs, municipality letters, contractor input and the intended scope.
-
Technical diagnosis
We identify the critical technical questions: structure, existing conditions, permit requirements, missing data and risks.
-
Drawings and calculations
We prepare the necessary architectural and structural information in a format suitable for review and coordination.
-
Dossier assembly
We organize the documents so the project is easier to understand for the municipality, contractor and client.
Where our technical focus makes a difference
Aboss is often involved when a project contains uncertainty: old drawings do not match the real situation, the municipality requests clarification, a contractor needs structural information, or the client needs a clear technical route before investing in construction.
Renovations and extensions
Drawings and structural checks for extensions, internal changes, roof structures and building alterations.
Load-bearing changes
Structural calculations and drawings for wall openings, steel beams, portals, floor openings and supporting structures.
Permit and legalization files
Technical documentation for permit applications, additional municipal requests and legalization of existing works.
Existing buildings
Careful interpretation of old drawings, visible defects, hidden structures and assumptions that must be verified.
Contractor coordination
Technical information that is not only calculated, but also understandable and usable during construction.
Risk control
Clear explanation of what is known, what is assumed and what still needs to be checked before execution.
Working area
Our primary working area is Amsterdam and North Holland. Depending on the project type and available information, we also support projects elsewhere in the Netherlands.
We work for homeowners, apartment owners, small property investors, contractors and clients who need practical technical support for drawings, structural calculations or municipal permit dossiers.
Frequently asked questions
What does Aboss Bouwadvies do?
We support clients with architectural drawings, structural calculations and technical dossiers for renovations, permit applications, legalization issues and structural building alterations.
Does Aboss only work in Amsterdam?
Amsterdam is our main region, but projects elsewhere in the Netherlands can also be supported depending on the project type, complexity and available documentation.
Can you help if the municipality has already asked questions?
Yes. We can review the request, identify what is missing and prepare additional drawings, calculations or technical clarification where required.
Can you help English-speaking clients?
Yes. We regularly explain Dutch building permit and technical requirements in practical English for homeowners, expats and property investors.
Do you guarantee municipal approval?
No consultancy can guarantee the formal decision of a municipality. We can, however, help prepare a clear, consistent and technically defensible dossier.
