Therme ARC

Therme ARC is Therme Group's in-house architecture practice and design company, with offices in Romania and Germany. The leading architects at Therme ARC develop spectacular and environmentally friendly architectural concepts that create an optimised environment of wellbeing.

Connected Green Architecture for the Cities of Tomorrow

Therme Group facilities are world-renowned for their ambitious and complex structures. Through state-of-the-art technology, Therme ARC designs some of the most sustainable buildings in the world. Therme Bucharest, for example, is accredited with LEED platinum in sustainability, equivalent to BREEAM Outstanding in the UK.

Therme Group facilities’ architectural design is central to creating their unique wellbeing ecosystems.

Designing Wellbeing For All

Therme ARC creates environments that foster wellbeing, where guests can connect both with nature and each other. In line with Therme Group’s mission to drive inclusive urban wellbeing, each resort is designed to encourage social interaction and ensure equality of access to space and facilities – a healthy, inclusive environment to spend free time in the city. Furthermore, navigation throughout the space is designed to be intuitive, generating a sense of openness for guests.

The biophillic architecture of Therme facilities bring humans and nature together in harmony.

The combination of state-of-the-art technology and design methods with natural elements ensures Therme Group resorts are truly unique.

An Interdisciplinary Approach inspired by Nature

Inspired by nature and bringing together specialists from botany, material science, philosophy and psychology, Therme ARC ensures that each new Therme Group building is a perfect ecosystem, catering to both human and environmental need. 

Using Therme Group’s propriety BioTrue™ system of development – a system founded in material and structural biomimicry – Therme ARC replicates highly sophisticated natural processes to develop structures that are sustainable, technologically advanced and in harmony with the natural world. These concepts of biophilic design also help to support visitors' wellbeing.

Therme ARC’s BioTrue designs takes inspiration from nature, using biomimicry to create environments optimised for human wellbeing. The shape of Therme Manchester’s wellbeing garden is inspired by the delicate folds of a rose.

BioTrue™ Architecture

Therme ARC understands that nature holds the answers to many design challenges. BioTrue™ architecture is Therme group’s interdisciplinary design system that, through technology, applies mechanisms from the natural world to inform visionary design concepts. 

The BioTrue™ system replicates with mathematical precision natural shapes, structures and functionality, resulting in ‘living structures’ that endure over time and are self-sustaining. Using this system, Therme ARC’s architects have found that nature can offer integrated solutions to a range of design elements including stability, wind dynamic responses, hydraulics and light and ventilation. 

By embracing nature as the original architect, Therme ARC applies natural design solutions that are high performing, visually appealing and energy efficient.

Therme ARC’s interdisciplinary approach allows it to deliver iconic projects across the world.
