I am a German architect with about 20 years of international experience in architecture and Master planning of various phases and scales.

After a period abroad since 2018 back to Germany I have experiences at doing building permissions, administration and coordination work applying my skills and competence on architectural and urban design with focus on sustainability.

Working in Europe and Asia between 2001 and 2017 has given me a very dynamic experience at different planning phases of mid-size and large scale projects, from the blue-print stage through to the executive, experiencing architectural, construction- and technical knowledge, executive planning, coordination work and preparing physical and virtual models.

My recent qualification as a DGNB consultant speaks to my interest of integrating eco- and sustainability schemes in project-orientated work. Currently I'm working at a construction company focusing on administration work. Prior to that I was employed in an architectural firm and in a development company.


My freelance employments between 2001 and 2017 have seen me integrated in international design firms in Europe, North Africa and Asia where I tried to applied and hone my skills in order to run projects, providing consultancy and coordination work. I’m used to independent and self-motivated work, often in team leading positions.

Widely experienced and proved work experiences:

  • urban Master planning
  • architectural from preliminary to approval planning
  • concept design (focus on sustainability, competitions and direct commissions)
  • coordination work, scheduling
  • preparing architectural models

Since I started working out of Europe my professional activities gained a focus on urban planning.

From 2014 till 2017 I held as Design Director c./o. RSP Design Consultants (India) Pvt.Ltd. in Bangalore (India) . After studying and working in Germany till 2001, my passion for history and art facilitated my move to Italy. In 2009 I followed an appointment as Senior of ECOU urban and architectural design team in Tripoli (Libya). It started there and developed further in Beijing (China) from 2011 till 2014 where I learned to handle large scale Master planning projects, due to my experiences often as team leader. Urban Master planning mixed with architectural design characterized also my job profile at RSP in India.

Urban planning:

  • high rise residential settlements, including facilities for business, leisure activities and shopping
  • business developments for the IT sector (in India)
  • high rise business district (new town center - competition) including a museum, exhibition facilities, art galeries, conference and performance center, residential areas
  • planning of access and traffic solutions including parking strategies

In Europe, I was working on an urban planning scale in:

  • reconstruction of street spaces in historical centres (incl. lighting, urban furniture)
  • urban analysis (guideline catalogue for urban development's of historical towns; guideline catalogue to develop an historical housing settlement)
  • environmental facility studies and planning (landscape and green planning of private and public space; design of a neighbourhood square)

and architectural scale in:

  • residential planning
  • office planning (a firm headquarter; a bank building - competition)
  • transport project (a railway station for high speed train network; a multi-storey parking lot; covered bus station)
  • industrial planning (production space in micro-electronic sector; a workshop pavilion)
  • planning for sport functions (indoor and outdoor)
  • hotel (a courtyard hotel; transformation of a residence into a boarding house)
  • educational (a school; university enlargement; kindergarten)
  • cultural (an open air theatre upon an ancient roman ruin)
  • institutional (mixed use cultural centre - competition)
  • hotels and accommodation
  • museum (restoring and enlargement of an exhibition hall; a museum)
  • housing (private housing, social housing, housing for groups with special needs like students and elderly people)
  • apartment (renovation)
  • mixed use (retail, office spaces, fitness and indoor and outdoor sport functions, gastronomy, housing)
  • transformation in an urbanistic scale (conversion of an industrial zone into a residential area, another in an educational and retail centre) and in an architectural scale
