architecture & building permits (hoai 1–9)

We accompany your project from the first sketch to the handover of the keys. Our office covers the full spectrum of service phases according to the HOAI. Whether a private residence or a complex public building: we handle the entire design and approval planning (building permit application) as well as all necessary coordination with the authorities. We ensure that your vision stands on a legally secure foundation.

interior design & spatial concepts

For us, architecture does not end at the facade. We design exclusive interiors that harmonize aesthetics and function. Our interior design includes detailed material and lighting concepts as well as precise space planning for private residences and prestigious public buildings. We create atmospheres that reflect the character of the building and generate lasting value.

renovation & technical standards (din/vob)

The revitalization of heritage-listed monuments and existing buildings requires the utmost precision. Our planning is consistently carried out in accordance with applicable DIN standards and current building regulations. For tendering and awarding contracts, we rely on the VOB to guarantee you maximum legal certainty and cost transparency. We make historical structures fit for the future – technically flawless and legally secure.
