Tilmann Lossen of Lossen Ingenieure impresses with his extensive expertise, experience, and highly professional approach. The combination of structural engineering, thermal insulation, and responsive project management is particularly noteworthy. – Pierre Lässig & Team, fonlos services GmbH & Co. KG
Tillmann Lossen and his team are the right choice when it comes to more than just a single-family home. As structural engineers, they are the competent experts for, among other things, extensions and timber construction. Reliable and dependable, with state-of-the-art tools like BIM planning, a large network, and the right company values, I am happy to recommend Tillmann.
Not only do they do what they do with the highest quality standards and always with a focus on sustainable solutions. HOW their results are brought to the world is also in tune with the times: people-oriented—whether that's their own employees, business partners, or society as a whole.
I worked with a team from Lossen Engineers and was always satisfied with their professionalism in structural engineering, their ability to listen, and their willingness to allow for creative freedom. That's how collaboration should be! High praise – I wholeheartedly recommend Lossen Engineers.
Clean work and friendly staff. Would gladly use them again!
