The modernised residential tower on Wiesbaden's Aarstrasse has a gross floor area of 9,560 m². The 2nd to 11th floors are reserved for THE FLAG Senior Living Wiesbaden - a serviced residential complex for senior citizens. There will be 65 barrier-free flats with living spaces of between 29m2 and 76m2 as well as magnificent views of Wiesbaden. The additional storey on the top floor will feature communal areas and a large roof terrace for all tenants. The first floor will be used for health-related lettings, which will ensure a high quality of life for the residents.
Externally, the remodelled building has little in common with its monolithic, austere predecessor. According to the design by Willen Associates Architekten, the façades will be partially greened and broken up by staggered balconies as well as staggered storeys. This creates a connection with the surrounding small-scale development and promotes a healthy microclimate, natural shading as well as sound insulation. It goes without saying that the building technology will also be modernised in terms of energy efficiency, which will reduce energy consumption by more than two thirds after the renovation.
On-schedule and cost-conscious construction creates trust
The conversion of office buildings into urgently needed flats not only relieves the tight housing market, but is also much more resource-efficient than a new build. However, conversion work is often a challenge for structural engineers. To ensure the load-bearing capacity, the shell was reinforced with a steel structure and CFRP lamellas. The extension is a lightweight construction.
As the existing underground car park is not approved for lorries to drive over, the delivery of building materials must be precisely coordinated with the suppliers and the various trades, which often work in parallel. We therefore use Lean Construction to manage the demanding processes on the construction site effectively and holistically," explains PORR Building Construction West Technical Director Bernward Schmitz and continues: "We are very pleased that we are now able to realise another project with our customer THE FLAG. It's great to see that our on-time and cost-conscious construction methods are bearing fruit."
