A 1970s terraced house in Eindhoven-Woensel had the partition wall between the living room and dining room removed. We provided the structural calculation for the steel HEA beam and the permit for the technical building activity.

The terraced house in Eindhoven-Woensel had the classic 1970s layout: a closed living room at the front and a separate dining room at the rear, separated by an approximately 10 cm thick load-bearing cavity wall. The owners wanted an open living space from facade to facade. The challenge lay in the cavity wall construction: both sides of the cavity had to be supported by a continuous beam carrying the upper floor and two bedrooms above.
We surveyed the existing structure along with the load path of the upper floor. The structural engineer calculated a composite HEA 180 beam to be placed in both leaves of the cavity wall. The bearings sit in the load-bearing external walls, with a stainless steel support point to avoid a thermal bridge. Because the wall is load-bearing, a permit for the technical building activity is required; we handled that application.
The home now has an open-plan living and dining room of 38 m² with an unobstructed view from the front facade to the garden. The HEA beam is neatly concealed within the ceiling. The structural engineer signed off and the permit was granted.
Key project details
What we delivered
Very happy with the input. The structural calculation for the wall opening was very thorough. No hassle with the municipality of Eindhoven.
Wall openingA permit-ready drawing for a wall opening starts from €599 incl. VAT at Tekenpunt. The exact price depends on the size and complexity; you get a fixed price upfront, with no surprise extras afterwards. Request a no-obligation quote.
That depends on the type of intervention and the rules of the municipality of Eindhoven. We check the aesthetic review policy and the zoning plan in advance, so you know where you stand and your plan typically passes the review in one go.
We plan the construction drawing by arrangement; rush is available for a surcharge. The permit procedure itself takes eight weeks for a regular application (Omgevingswet).
