Simon Käslin has supported me on several construction projects. He always does so with great professional expertise and an open, approachable manner.

Lorenz L., Zurich
The collaboration with raumwert+ was a complete success. [...] Thanks to their optimisations, we were able to gain more usable space, reduce construction costs, and increase quality – all without compromising the concept. A definite recommendation for anyone who wants to realise the full potential of their project.

Mark S., Thurgau
Simon reviewed the project for accuracy, clearly explained the key points, and drafted an objection. The construction plans were subsequently revised and adjusted. His assessment was thorough, clear, and very helpful. Highly recommended if you are looking for an independent and expert second opinion.

Balz K., St. Gallen
We first used raumwert plus's free basic screening to have our project reviewed from a fresh perspective. Even then, Simon clearly showed us where there was still untapped potential: especially in space utilization and construction costs. After that, the 360° project optimization went into much greater detail with tangible results: more usable space, smarter structures, and reduced costs. [...] For us , a clear win, both in terms of content and finances.

Franziska S., Zurich
