With its monumental concrete pits floating a meter above a light glass box is the administration building for the glass company J.A. Alstrup, designed by architect Knud Blach Petersen in 1967, a significant exponent of the business architecture of the 60s and 70s and one of the first examples of an open office landscape in Denmark. Realdania By & Byg buys the property to secure an icon from late modernism and provide concrete solutions for concrete renovation.

"We are pleased with the acquisition of Glasalstrup's administrative building, which, with its huge roof structure - a concrete concrete cast on site - is a unique exponent of late modern business architecture. Concrete as a building material is eroded by many, but when used as in the case here, the term becomes completely unique. With the acquisition, we will ensure the property the best possible future conservation through sustainable operation and use," says Peter Cederfeld, CEO of Realdania By & Byg.

The administrative building is now part of Realdania By & Byg's collection of over 60 historic properties that represent Danish building culture for 500 years. Awaiting extensive restoration awaits must ensure the operation of concrete structures and future life.
