Responsible and healthy building

Your building project — Sustainable by design

I support homeowners, contractors, and architects in creating healthy, sustainable indoor spaces using bio-based materials and moisture-regulating, vapour-open construction techniques.

A focus on detail

What is the priority for your project? Together, we define the essential goals for your build or renovation. Whether you are aiming for an optimal indoor climate with clay or lime plaster, focusing on natural insulation materials, or require specialist support for technical detailing and making the building envelope wind and airtight, I provide the necessary expertise.

Water, wind, and airtight construction

Vapour-open, vapour-tight, or vapour-retarding? Where should membranes and boards be used, and where must they be avoided? As conventional and bio-based construction methods increasingly intersect, incompatible combinations can arise, leading to severe moisture issues or structural failure. A precise technical detailing review prevents these errors at the source. If you require a second opinion on your architect's or designer's details, I am here to provide a thorough assessment.

Expert material consultancy

Natural insulation only performs when correctly applied. I consider acoustic and thermal values, phase shift, and moisture balance to find the right fit. While there are many ways to build, not every build-up is practical for every situation. My advice prioritises your requirements—ensuring that plumbing and electrical installations are integrated without compromising the airtightness of the walls.

Radiant heating design

I provide expert guidance on various heating systems, weighing the pros and cons of underfloor heating versus wall heating, or identifying when ceiling heating is the optimal solution. With years of hands-on experience, I can explain which system best suits your specific build. Based on a detailed heat loss calculation, we can design a plan that ensures your heating system perfectly matches the thermal demands of your home.

Supervision and execution in bio-based construction

Consultancy Insulation Clay Plaster & Wall Heating

I provide expert guidance on the selection and application of bio-based and circular building materials. My services also include specialized installation, such as clay plastering and the integration of wall, floor, and ceiling heating systems.

Project execution

I bridge the gap between technical expertise and a hands-on approach, turning a practical plan on paper into the ultimate living comfort. There is nothing more rewarding than creating what I call a 'warm hug wall' for my clients: - Wood fibre insulation paired with wall heating and clay plaster - Underfloor heating finished with natural timber flooring - Ceiling heating finished with clay plaster - And much more. I work with meticulous attention to detail to bring a fresh, positive energy to your home. (For larger projects, I frequently collaborate with a trusted network of fellow independent specialists.)
