ISOAUSBAU GmbH –

"You can't build character – but you can preserve it."

ISOAUSBAU GmbH stands for modern interior design concepts in existing buildings. We combine substance with style, renovation with sensitivity – and develop solutions that respect the value and history of a building.

With a specialisation in renovation and interior finishing in existing buildings – for commercial, public and institutional clients.

Administrative buildings, school buildings, office spaces and large-scale residential complexes are just as much a part of our range as special technical cases during ongoing operations.

We bring experience from numerous complex existing projects to the table, think ahead, and deliver solutions that are architecturally viable, economically sensible and technically precise.

Renovation & modernisation of old buildings
From complete interior fittings to the targeted renewal of individual aspects – tailored to the building type, year of construction and usage concept.

Interior design & drywall solutions
New floor plans, modern room layouts and intelligent wall and ceiling systems for more light, air and structure.

Bathroom renovations & tiling
Contemporary bathrooms with a clean aesthetic, high-quality surfaces and clever room layouts – even on the smallest floor plans.

Floor coverings & surfaces
Harmoniously coordinated materials and colours: parquet, vinyl, laminate or tiles – depending on the usage and design requirements.

Substance analysis & technical evaluation
We evaluate the building structure, use, existing technology and requirements – the basis for reliable renovation concepts.

Planning & coordination
Our approach is interdisciplinary: with us, architecture, specialist planning and construction management work together seamlessly.

Implementation & documentation
Each stage is transparently documented – for security, traceability and a clean handover.
