ARCHITECTURAL FOCUS
The pavilion likens the Czech Republic to a shared landscape made up of millions of cultivated gardens with a single sky above . exhibition pieces . The building is meant to represent the Czech Republic as a work of art , therefore the design reflects contemporary building technologies and traditional Czech know-how . This philosophy is also reflected in the interiors , which are furnished with high-quality Czech products and the leftover material from the CLT panels .
Environmentally friendly operation and transport
On the way up , they are accompanied by a stream fed by rainfall , of which there is no shortage in Osaka . The pavilion ’ s interior engulfs visitors , allowing a view of the sky created by the projection . The ground floor is a public space with a covered atrium . Two staircases connect the entrance area with the second floor . Individual unique 3D-printed steps form a micro landscape right in the middle of the building , a touch of nature in an orthogonal system of wooden columns and panels . The second floor is dedicated to Czech cuisine , the way the interior is arranged encourages interpersonal contact . Above the gastro corner is a multifunctional auditorium that is actively integrated into the curated dramaturgy of the pavilion , a multimedia stop on the way up .
On the last level of the building , two worlds - the sky and the garden - interpenetrate . The sky under the garden roof is both an exhibition space and a venue for private events . In the delicate web of the load-bearing structure , artistic artefacts intermingle with functional objects . The indoor exhibition has direct access to the garden terraces .
The pavilion is designed as a prefabricated wooden building made of glued timber and wooden panels laid in a square grid . Emphasis is placed on premium appearance , optimum thicknesses , high load-bearing capacities and precise joints . The building envelope consists of CLT panels in combination with double glazing . The gallery space under the garden is clad with laminated glass slats . The walking surface in the parterre is a brushed concrete slab with recycled material from construction debris . Natural light is provided by the glazed parts of the façade and the open atrium . The primary energy source for hot water heating is waste heat from the building cooling and grey water effluent . The green roof serves to improve the microclimate , natural cooling and rainwater harvesting . The water is filtered through the root system of the green roof and further used , among other things , for fine mist sprinkling and central irrigation of the roof garden . The entire building is designed in a passive standard , with a consideration of its possible future dismantling and relocation . The logistics of construction were also taken into account in the design . The panels , beams and additional structures are designed for easy container transport , assembly and disassembly .
Materials
The building is designed with a combination of CLT panels and BSH ( glued laminated timber ) beams , which clearly defines its materiality .
The timber structure is complemented by 3D-printed concrete staircases and a subtle steel roof superstructure , which is covered by a ventilated float glass façade system under the living roof . These materials permeate the entire design . We are not trying to hide them , we are revealing them in their natural beauty .

The garden , too , is an exhibition space , a territory for children ’ s play and a place where visitors can relax and also contemplate under the trees the direction our fragile world is heading .
The landscape design of the pavilion is a reminiscence of the mosaic structure of the Czech landscape . The roof landscape of the pavilion is varied , with different heights showing the diversity of surfaces , the structure of stems , trunks and branches , the texture of leaves and the changing colours during the seasons . On the roof , a small brook springs up and weaves its way through the pavilion , ending in a pool in the parterre . The surface mirrors the clouds , the visitors and the entire exhibition , reinforcing the idea of tying people ’ s lives to the weather , the cycle of the year and life .
The central motif of the garden is also transferred into the form of contemporary floral illustrations . The abstracted flowers of marigolds , sunflowers , morning glories , poppies , four-leaf clovers and brooklily leaves are depicted with a delicate stroke of a line , loosely referring to the technique of Japanese calligraphy and the delicate illustrations in Karel Čapek ’ s The Gardener ’ s Year .
The principle of the design is a building that is not just a box for
