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.
