Architecture studio YOD have renovated and modernised a Soviet-era building in a Ukrainian pine forest to create a nature-inspired spa and leisure complex.

The facility is an extension to the newly-built Relax Park Verholy Hotel, located in the Poltava region, which the Kiev-based studio designed last year.

The new complex features a spa and sauna, an indoor swimming pool, a cafe, a fitness centre and 17 additional hotel rooms – with all interiors created using veneered plywood to create a link between the building and its peaceful surroundings.

“We kept to the minimalist aesthetics of the whole complex and used natural materials only,” said YOD in a statement. “The architecture of the building is modern and discreet and the main idea is to let nature be the main actor on the stage. There are no unnecessary details in this open and laconic area.”

In the spa, soft colours and dimmed lighting have been used to add to the atmosphere of relaxation, while colourful photographs of Ukrainian competition-winning horses line the walls to reference the region’s equine traditions.

Different rooms have been created for different kinds of treatments, including a hammam, an infrared sauna, a Russian bath and three massage rooms. There are also two heated pools and a jacuzzi zone.

Rust-proof metal and anti-slip flooring have been used to for the jointless walls and floor construction, preventing dirt from accumulating and making the area safe to use for guests.

The complex also has a fitness centre – with equipment supplied by Technogym – and large panoramic windows look out towards the forest and a local racetrack.

A connected phyto-bar provides guests with fresh juices, herbal tea and a detox menu for health improvement and body toning.
