2022 can only get better!

2021 was not the best year, both on personal as professional level. Both my father and my friend-client Johan Grootaers died. To close this year and as a tribute to them I want to show you 4 of my favorite 2021 projects (all together with Johan). Hope to continue the work on natural building stones in 2022. So, this is also an open invitation to help you with determination of natural building stones:
- Errerahuis, Brussels, official residence of Flemish Prime Minister
- Abdij van Park, Heverlee (Leuven), Floor in Refectorium
- “den Grooten Cruywaeghen”, Mechelsestraat 37, Leuven: facade
- Roof of Meir 47, Antwerp: facade and roof
Best wishes,
David

Facade restoration of ‘den Grooten Cruywaeghen’ in Mechelsestraat in Leuven is a nice job. Challeging to analyse the different applied (weathered) natural building stones and give scientifically based advice.

I wish you all the best for 2021. I hope next year our paths will cross again.
