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. No permit required; the contractor could start the next day.

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 intervention is entirely internal, no building permit is required.
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 contractor completed the demolition and beam placement in 1 day. No permit required, no contact with the municipality. The structural engineer signed off.

What we delivered
A permit-ready drawing for a structural opening starts at Tekenpunt from €595. The exact price depends on the scope and complexity; you receive a fixed price upfront with no additional billing. 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 deliver the construction drawing within 0-3 weeks, or 0-2 weeks on an urgent basis. The permit procedure itself takes eight weeks for a standard application (Environment Act).
Whether you live in Eindhoven, Noord-Brabant or elsewhere in the Netherlands: we handle design and structural calculation from A to Z. Since 2016, 800+ projects. A no-obligation quote within 1 working day.
