Termalija Family Wellness is the latest in the series of projects which we have built at Terme Olimia in the last fifteen years and concludes the complete transformation of the complex from a classic health centre built in the 1980s to a modern relaxing thermal spa. The transformation has been characterised by its gradual nature – each step was carried out in response to the then-current needs and did not follow any preconceived development plan. In fact, every new building was believed both by the investor and by ourselves to be the last.

Termalija Family Wellness By ENOTA - Sheet8The usual development of such complexes results in a series of extensions that slowly fill the space and do not conceal their origin in terms of either the period or the design. We took a rather different approach in the renovation of Terme Olimia, and with each new building, we tried to improve the situation also in terms of the urbanism. At the same time, we invested a lot of effort into designing the buildings in such a way that despite the new programme added each time, the buildings do not actually fill the space but connect it even more with the nature that surrounds them.

Termalija Family Wellness By ENOTA - Sheet9The same applies to the Termalija Family Wellness. The new facility is located at the site of the former wintertime covering of the outdoor pool. The cover was supposed to be retracted every summer to free up the scarce outdoor space, but in practice, this was never done because of the complexity of the retraction process. With its size and form, the membrane covering of the outdoor water surfaces stood out considerably from the surrounding built structure.

Termalija Family Wellness By ENOTA - Sheet10While the previous projects were the result of the wishes of the investor, this one was actually proposed by us. The existing winter covering was a definite detriment to the guests’ experience of this otherwise very naturally designed complex. But this was not the sole reason: in its programme and design, the old part featuring thermal content stood in stark contrast to the new one, giving rise to mounting complaints from guests who wanted the service to be on an equal level. This persuaded the investor to go ahead with this last step of the transformation of the entire complex.

Termalija Family Wellness By ENOTA - Sheet12Previously, a greater portion of the building was cut-and-filled under the surrounding terrain with each subsequent project, which reduced their presence on the site. In the case of the Termalija Family Wellness, however, we weren’t able to simply repeat this design approach. The volume of the necessary space, especially in the area with water surfaces, required the siting of a much larger structure which could not simply be buried below the grade. No longer being able to reference only the surrounding natural landscape, the solution was found in the scale and form of the surrounding vernacular structures.

Termalija Family Wellness By ENOTA - Sheet14While we were still able to design Termalija’s supporting programme in the same way as we had previously done Orhidelia, the large roof above the water area was divided into sets of smaller segments to prevent its scale from overwhelming the surroundings. Viewed from a distance, the shape, colour, and scale of new clustered structure of tetrahedral volumes is a continuation of the cluster of the surrounding rural buildings, which simply visually extends into the heart of the complex.

Termalija Family Wellness By ENOTA - Sheet16The resulting fine structure of volumes has enabled us to solve another important task. The seemingly complex geometry gives the new roof static strength, allowing the entire pool space to be covered virtually without supports. In this way, the new roof floats above the pool platform, which is designed as an exterior space. Due to the lack of outdoor spaces in the summer, it was imperative to examine solutions which would deliver the same closed space used by the guests in winter as an open space in summer. Numerous skylights in the roof, together with the ability to fully open all the facade glass surfaces, enable the guests to seamlessly pass through the interior of the building. Despite its size and the space it occupies, the new roof simply acts as a big summertime sunshade and does not usurp any of the precious exterior space.

ENOTA was founded in 1998 with the ambition to create contemporary and critical architectural practice of an open type based on collective approach to development of architectural and urban solutions. ENOTA’s team of architects focuses on research driven design of the environment where study of contemporary social organizations and use of new technologies are interwoven to produce innovative and effective solutions. ENOTA’s solutions are strongly influenced by research, reinterpretation and development of social, organizational and design algorithms that derive from nature. The result is always a strong binding of the buildings with the environment that surrounds them. Over the years ENOTA has been constantly developing and from its beginnings it has served as creative platform for more than fifty architects. ENOTA is led by founding partners and principal architects Dean Lah and Milan Tomac.

ENOTA’s projects vary from residential and office buildings to hospitality, cultural, leisure and sports facilities as well as public spaces. Main built works include Promenada Velenje (2014), Ptuj Performance Center (2013), Stambolžioski Dental Studio (2011), Podčetrtek Sports Hall (2010), Wellness Orhidelia (2009), Gruškovje Border Shop (2009), Ilirska Apartments (2008), Terme Tuhelj Spa Resort (2007), Jurčkova Housing (2007), Hotel Sotelia (2006), Wellness Centre Termalija (2004), NKBM Bank Branch (2002), Kraški zidar Headquarters (2002).
