The construction of the elaborate building, made mostly of wood and glass, was completed in February and work has since focused on equipping the building and giving it its final look.

The SPIRIT tourism and investment promotion agency overseeing Slovenia's participation at the expo said it fully expected the building and its surroundings to be ready to accept the first visitors when the global fair opens on 1 May.

Slovenia was among the first countries to complete construction of the pavilion and focus on what it will offer to visitors.

Featuring a pyramidal shape, the inside of the building is divided into five spaces each hosting the key themes that the country will promote: salt, bees, thermal and mineral water, healthy lifestyle, and green technology.

In addition to its futuristic shape, the building has focused on the use of sustainable materials and construction methods.

For an even more distinctive feel, the interior will feature live elements, such as walls covered with grass, moss and fern to highlight its environmental features.

Wood was used as a central building material to highlight Slovenia's rich forest resources and its commitment to modern building trends, which have focused on state-of-the-art use of wood, said Bruno Dujič of CBD, the company in charge of project design.

The building, measuring 83 metres in length, 14 metres at its widest point and nine metres in height, required 3,000 sq. metres of wall and ceiling elements on top of some 35 tonnes of steel frames, according to Lumar, the company which built it.

The large glass facades will allow interaction between the interior and exterior are designed to get passers-by to take a look inside, said Edi Blažko from the architects SoNo arhitekti.

The landscape surrounding the building will consist of gardens featuring plants native to Slovenia. Four themes will be represented, director of the landscaping company working on the garden Tomaž Čufer said, consisting of olive trees, aromatic plants, herbs, conifers, vines and rosemary.

A total of 2,400 hours of work was spent on building the pavilion, with material having been brought to the venue by 25 lorries.
