Making buildings fit for a second life
For good reason, the demand for revitalising or converting (change of use) buildings is increasing: resources are becoming scarcer and require sustainable use of valuable substances.
Modern architecture stands under the signs of protecting, preserving, restoring. We provide all HOAI service phases to make buildings fit for a second life, taking into account the structural and cultural context.
Modernisierung einer Ikone
Preserving and enhancing value
The basis of every good revitalisation is an intensive analysis of the existing stock. 85 years of company history also mean that we often make our own buildings fit for a second life. We know from our decades of experience, where surprises can be hiding, even in buildings that we did not build, and therefore recommend thorough analysis of the building structure.
Claudia Roggenkämper, Partner HPP
"A sucessful revitalisation project depends on a thorough analysis of the existing structure."
During the analysis we get to know the identity of the building: What are its strengths, what are its weaknesses? For example, is a conversion, i.e. a change of use of parts of the building or the entire building, possible? Only when these questions have been clarified do we deal with the technical questions of fire and noise protection, building physics, acoustics, etc. Here, too, we always seek solutions in dialogue, especially when conservation is an issue.
The early involvement of the authorities makes it possible to find solutions that preserve identity and at the same time are pragmatic.
The only good listed building is living, functioning listed building that is put to good use.
Our philosophy: The only good preserved building is a living, used and functioning one! For this reason, we preserve the values of each building, but also find solutions to further enhance and develop its use.
Refurbishment means modernising the energy systems e.g. laying new pipes and cables, new heating and cooling systems, all other new technical systems, fire protection. The existing building is conserved.
Changes to the existing building that go beyond refurbishment of the energy systems (both on a physical and aesthetic level), e.g. the demolition of partition walls to create open-space areas for modern working environments or to improve access.
Mit Konversion bezeichnen wir die Umnutzung/Funktionsänderung eines Gebäudes, z.B. aus einem Bürobau wird ein Wohnungsbau oder aus einer Industriehalle ein Bürogebäude. Meist erfordert dies den größten Eingriff in die Substanz.
Bei allen drei vorgenannten Aufgaben kann das bestehende Gebäude unter Denkmalschutz stehen. Je massiver die Eingriffe sind, desto intensiver stimmen wir uns mit dem Denkmalschutz ab.

The old charm restored
to new splendour
In the case of valuable and listed properties, we are generally in favour of renovation. This is demonstrated by buildings that we have built and modernised decades later, such as the Emporio Tower in Hamburg, the former Unilever Tower, the Dreischeibenhaus in Düsseldorf or the Finnlandhaus in Hamburg. In addition to energy-efficient upgrading, the sustainability of such projects consists in preserving the existing architecture while conserving resources.
In the case of an office property without a special identity or functionality, it may be that (partial) demolition or conversion is preferable to refurbishment. The opportunity: to develop a completely new identity for the building.
For example, maxCologne: Hochtief's project developers commissioned us at the time to do just that for the modernisation of the former Lufthansa high-rise in Cologne. The result is a completely new architecture.
Enabling modern uses
Since our working worlds are increasingly developing into 'open-space areas', in the future even the deepest existing floor plans will have a chance of redevelopment. They allow a communicative organisation with glass meeting areas and conference zones in the central axis.
