Structural engineering
Structural calculations, structural drawings and details, building inspections and wall openings.
A building plan calls for clear choices, reliable drawings and the right technical information. ABOSS supports private individuals and businesses in preparing and developing a project-specific dossier.

The required drawings, calculations and additional documents are tailored to the activity, location and phase of your project.
The services are organised into five groups. Choose the group that fits your question; from there you will find the related topics and projects.
Structural calculations, structural drawings and details, building inspections and wall openings.
Extensions, roof extensions and dormers, foundations and demolition, full renovation.
Concept design, facade architecture, 3D visualisations and construction drawings.
Environmental permit, permit-free building advice and legalisation files.
A selection of project locations in Amsterdam and the surrounding area.
From the first drawing to the complete permit application. Most detailed service pages are in Dutch; selected topics are available in English.
We check whether your plan needs a permit, prepare the dossier and guide the application through the Omgevingsloket.
Floor plans, elevations, sections and details — from a simple line drawing to a complete permit set.
Calculations for wall openings, steel beams, extensions and roof extensions to the Eurocodes.
Extra living space without moving: design, drawings, structure and permit from one team.
More space in or on the roof, including the permit check and the load-bearing structure.
Signs, lightboxes and projecting signs: permit check, notification and drawings.
ABOSS Bouwadvies & Tekenbureau has supported private clients and businesses in Amsterdam and the surrounding area since 2001 — drawings, structural calculations and permits from one team.
You describe your plan and the address; we assess feasibility and the permit route.
Archive drawings or measuring the existing situation.
Drawings, calculations and supporting documents for your plan.
Submission through the Omgevingsloket and guidance until the decision.
That depends on the type of work, the location and the dimensions. A good first step is the official permit check (Vergunningcheck) in the Omgevingsloket; we then assess your specific situation.
The price depends on scope, complexity, level of detail and timing — from a simple line drawing to a complete permit procedure. You receive a quote without obligation beforehand.
Mainly Amsterdam and the surrounding area, and elsewhere in the Netherlands on request.
