What exactly does your owner's construction advisory include?

Owner's construction advisory encompasses all project components. I provide comprehensive support to clients in strategic decisions, interpretations, addressing questions, and in all matters necessary for project success.

Who is building consultation suitable for?

My consulting services are aimed at real estate developers, investors and building owners who want to strategically optimise their project early on and make well-founded decisions.

In which phases of a construction project can I make use of your owner's construction advisory services?

Owner's construction advisory can be involved in all project phases, but ideally as early as possible to provide optimal support for strategic planning and key decisions. This can be done on a case-by-case basis or over the long term.

What specific added value does your owner's construction advisory offer for my project?

The tangible added value of our owner's construction advisory lies in the fact that you can make well-informed decisions based on a clear analysis. This allows you to avoid costly mistakes, manage your construction project more safely and effectively, and ensure a smoother overall project progress.

How does your owner's construction advisory differ from traditional owner's representation?

Owner's construction advisory is primarily understood as independent support, not operational project management. I advise clients, assist with important decisions, and ensure that these decisions strategically align with the functional, aesthetic, and economic project goals at every stage.

How do you calculate your fee for consulting services for building owners?

The fee for owner's construction advisory is calculated either as a fixed amount or on an hourly basis, depending on the project size and complexity. After an initial consultation, you will receive a transparent quote that clearly outlines the anticipated workload.

Here's what our customers say

The following feedback demonstrates how collaboration leads to sustainable project success. Read more Google reviews of raumwert plus GmbH.

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
