Hotel of the “Gründerzeit” epoch. From 1930 onwards the use of the building was destined to that of a hotel, practically without it having gone through any rehabilitation since that date. The total rehabilitation took place in 2007.

State of the work

Case windows with mono-crystal. Bad quality of both the opening and closing systems, as well the ironworks and handles, where the exterior ones were especially damaged. Serious damages in the wood, especially in the exterior part. Different paint layers in a very bad state of preservation.

Diagnosis

According to the guidelines of the Patrimony of Protection Office, the exterior façade of the windows had to be preserved. The windows presented a state of abandonment which disabled the possibility of proceeding with their renewal. The new fabrication, reproducing loyally the original windows, was the only road to follow. The interior parts of all of the windows had to be fabricated again, integrating all the elements that the actual technologies supplied for a perfect thermal and acoustic protection.

The main problem consisted in that the lintel was of little depth, which made the window have to adapt to such scarce lintel depth and therefore preventing it to open towards the inside.

Solution

By enlarging the depth of the windowsill, as well as enlarging its height allowed to solve the problematic.
