Renovation of a 100-year-old garden pavilion in Frauenfeld, Switzerland

“Our Pavilion is clearly the jewel of our property. About 4 years ago, practically all professionals and builders we know believed that this dilapidated garden pavilion would no longer be reasonable to save. Jan Stelcl seemed to be the only one still seeing a future in it. And indeed, with a lot of tenacity and commitment, he brought this neat building back to bloom. This was not the only challenge. The pavilion also had to be rebuilt about 30 meters to the south, away from the road to a quieter corner of the garden. So the dilapidated pavilion had to be detached from the foundation and moved to another location by crane.

Then the newly renovated pavilion got its worthy place, the rotten boards were replaced, replastered and the roof was erected in a new and stable way. The rain gutter received a decorative drain and also the new paint on the pleasure house now invites one to enter. It was worth it!

Everyone can feel that this was not only a technician at work, but an engineer with heart.”

Renovation of manor House by Dolni Kounice, Czech Republic

“I own a historic building that was leaking and as a result the beams were rotting. The property had become unusable. I consulted with various engineers and Mr Stelcl came up with a very sensible solution. He struck a wood-concrete composite ceiling – the beams are connected to the concrete with the help of a screw. This construction has the advantage that much is historically preserved, but at the same time these floors have become fully functional.

Mr. Stelcl proposed wise solutions in which the deflection of the structure should be a maximum of 1-2 cm with a span of the beam of 7 m. Currently measured with the help of a laser, I am at 0.7 cm. Mr. Stelcl suggested sensible solutions and above all he was always helpful in the video chats. I am thankful for his advice and as a result I saved a lot of money.”
