Spaces influence people – and, as a result, the value of a building.
They influence sleep, concentration, recovery, and well-being. For modern architecture and responsible planning, this aspect is becoming an increasingly crucial quality feature. Gingkos combines material technology with the benefits of building biology.
Our solutions harmonize spaces in a subtle, gentle, and lasting way – inspired by the ginkgo tree, a symbol of endurance, balance, and protection.
This provides planners, developers, and architects with a new way to set themselves apart: buildings that are not only technically impressive but also tangibly beneficial to people.

Your Benefits – Cost-Effective, Reliable, and Value-Adding

Businesses & Commercial Spaces
By harmonizing geopathic stress fields, a stable and pleasant work environment is created that promotes satisfaction, concentration, and productivity. At the same time, reducing moisture and mold protects the building’s structure and helps preserve the property’s value over the long term.

Hotel & Wellness Facilities
Feng Shui-inspired architecture and geopathically balanced spaces can be promoted as a compelling quality feature. This allows you to attract new guest groups and offer a tangible sense of well-being – from a more restful sleep to deeper relaxation.

Private Homes & Residential Buildings
Effectively reducing radon levels and harmonizing geophysical stress fields promote the physical and mental health of residents. At the same time, protection against moisture and mold improves the indoor climate and helps ensure a durable building structure that retains its value.
