This portfolio shows several solutions for creating an opening in a load-bearing wall: straight, round and semi-circular. Aboss provides the complete technical package: structural calculations, structural drawings and, where required, permit support.
The goal is not only a visually strong opening, but also a safe load path, clear execution details and a dossier that works for contractor, client and municipality.
Creating an opening in a load-bearing wall directly affects the structure. Depending on the building type, location, heritage status and scope of the alteration, it may require a permit or formal notification. Even where no formal permit is needed, structural substantiation remains essential for safe execution.
Practical start: send the project address, a few photos and any existing PDF drawings. We can then advise on the most logical route.
In Amsterdam, structural openings often involve older buildings with masonry walls, timber floor structures and existing settlement or deformation. That requires extra attention to bearings, cracking risk, site method and phasing. In listed buildings or protected areas, the dossier strategy should be defined early.
Aboss operates from Insulindeweg 649 in Amsterdam and supports projects in Amsterdam and surrounding municipalities.
A wide opening improves sightlines, daylight flow and functional connection between rooms. The supporting steel can be designed as a straight, round or semi-circular solution, depending on the interior ambition, available build-up space and existing structural conditions.
If you want to combine living room and kitchen or connect two rooms, a structural opening in a load-bearing wall with a steel frame is a common solution. Aboss handles the technical route from assessment to calculations and drawings, so the contractor can execute the work safely and efficiently.
We provide structural calculations and technical drawings. When required, we also support the wider process, including architectural coordination, dossier logic and contractor or municipality communication.
Whenever the wall is load-bearing or contributes to structural stability, a structural assessment is needed to ensure safe execution and to reduce technical risk.
Often yes, but it requires careful detailing, dimensional control and a proper review of the wall build-up, bearing conditions and finishing space.
The project address, a few photos of both sides of the wall, approximate dimensions of the intended opening and any existing PDF drawings are usually enough for a first technical proposal.
Send the address, photos and your preferred opening. We will respond with a practical route and price indication.
