What exactly does the second opinion include?

The second opinion service analyses individual project components independently and critically at your request. This can involve very specific topics, such as reviewing a floor plan, a purchase contract, or a schedule. The goal is to provide a well-founded second opinion.

Who is a second opinion suitable for?

It is particularly suitable for people who already have documents such as floor plans, layouts, or other materials, but are unsure whether these are coherent, economical, or represent the best solution. A well-founded second opinion is especially worthwhile for major decisions.

What specific added value does your second opinion offer for my project?

You will receive an independent assessment that provides clarity and uncovers blind spots. This allows you to avoid negative developments, better utilise project opportunities, and make decisions on a sound basis.

At which phases of a construction project can I seek your second opinion?

A second opinion can be obtained at any time and tailored to your individual needs.

How do you calculate your fee for a second opinion?

The fee depends on the scope and complexity of the second opinion. We generally work on a flat-rate basis. After a brief initial consultation, you will receive a transparent quote.

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.
