The substructures of the concrete instrument stands of the observation rooms had to be Laid deeper than the walls, 3 metres below pavement level, and they were covered with "hard plate" carved from limestone quarried in Süttő. Designs of the steel roofstructure which could be pulled over the corridors of the corner pavilions were made by the engineering office of Schlick's Iron Foundry and Machine Works Co. The same company was commissioned with manufacturing and execution.

The walls and the vaults above the corridors were made of brick. The wooden structure of the low-pitched gable-roof to the central pavilion was tiled. The building featured wood cement cladding and cast jointless floor, heating was provided by a stove fuelled with gas. Ironmongery (hanging conduit pipes, drains, roof trap-doors, dormer windows] were made by János Bründl. A wide pavement was made to skirt the building. The permit to use the observatory was signed on January 10th, 1910.

There is no data available about the damage done to the Geodesic Observatory during World War II. A bomb hit the south-western corner of the courtyard wing of the Central

Building. In the photo made in 1942 the observatory is still documented, which means it must have been destroyed sometime during the siege of 1944-1945. The last site plan (scale 1:250) still showing it was made in 1947 for a geodesic survey which rates the building as "ruin". The observatory is already missing from the general plan of the building site documenting the area of the Campus dated June 23rd, 1948.
