Covered in polycarbonate sheets, The Droplet is a transparent pavilion of 25 sq meters area designed by Copenhagen based architect Kristoffer Tejlgaard.
Pavilions have for long been subsidiary structures installed either freestanding or connected to some buildings. Some assemblies like the Pollution Pod act as travelling exhibitions whereas some are multi functional like the Escape pod. Recently the Komorebi pavilion developed by architecture students of Harvard School of Design and engineering researchers from University of Tokyo showed a non traditional form and random patterning system.
The Droplet pavilion was created out of curiosity of having a contemporary structure as an alternative to conventional glazed greenhouses. As per Kristoffer Tejlgaard, the pavilion is an “engineered self-supporting dome, which can function as a garden pavilion, greenhouse, mobile exhibition, recreational space or whatever your imagination allows you”.
From the designer –
Design and functionality –
“The droplet consists of sheets in transparent 6mm polycarbonate sheets. The sheets are assembled with stainless steel nuts and bolts which allows for an easy and fast build and disassembly. The curvature of the structure is generated by the rhombus shapes of the flat sheets and by displacing the holes slightly between the overlapping sheets in a controlled manner”.
“In order to reach the required precision, CNC-milling is used for the sheets. The curvature of the facade gives the pavilion incredible strength, which allows for the simple and thin facade without the need for internal load bearing walls or steel frames.
With an oval profile and circular footprint the design maximizes available floor space and standing height along the inside of the facade. The polycarbonate sheets are designed to overlap in a fish scale fashion, keeping the structure wind and waterproof, without the need for seals or caulk. The droplet can be tailored to accommodate each client’s needs – from the type of foundation to size, shading, facade solution, transparency level and interior layout”.
“The price of the droplet begins at DKK 94.000 but will vary depending additional acquisitions”.
As a part of customisation, the droplet can be fitted with aluminium or wooden doors and a PEHD thermoplastic foundation ring extended 50cm into the ground to keep rodents at bay. Colours can be varied on the aluminium doors and the foundation. To keep sun at bay, a cotton awning of varying sizes can be attached to the pavilion via stainless steel hooks from within. The base of the pavilion made from 3 interlocking CLT pieces (Cross Laminated Timber) serves as a sound base foundation-an ideal solution for mobile exhibitions! Various ways of maintenance such as annual cleaning and addition of rubber strips or thermoplastic transoms at joints have been proposed by the designer.
Design process –
“For Kristoffer Tejlgaard personally, the fascination with domes, at first geodesics, started with the American architect Buckminster Fuller and his ideas about ecological design. Since Kristoffer erected his first geodesic dome at Roskilde Festival in 2011, several other geodesics have been added to the portfolio. An earlier project, Dome of Visions is a construction of the geodesic type. A method of engineering with which one can create strong and sturdy, but still delicate designs, by deliberately orchestrating the compressive and tensile forces of materials.”

As a result the designer strongly emphasizes that it was Buckminster Fuller who revolutionized the geodesic geometry to construct domes. His foresight of dwindling resources of 21st century made him create resource efficient intelligent constructions. Well, that’s the reason that we see a lot of smart pavilions in the field of architecture and design. Living on the same legacy, Atelier Kristoffer Tejlgaard keeps challenging and evolving established construction methods in these arenas.
For the Droplet project which seeks to meet modern industrial production, a geometry based on rhombuses was developed using 3D-modelling. Usually for geodesic domes, pentagons and hexagons shapes are commonly used. As per designer due to the rhombus shape adopted, material waste could be reduced to 62%. Also the polycarbonate sheets used have been cut to take full advantage of the standard sheet sizes.
Pavilions often are seen as space occupying structures after serving its purpose especially for exhibitions. Taking this into account the Droplet is designed for disassembly. The structure can be easily recycled after it serves its function.
On site assembly of prototype –
‘The Droplet arrives to the building site on pallets, where the flat sheets for the facade contain an engraved number code system to ease the assembly process. The sheets measuring a maximum of 1×1 mt are easily handled by two people and even manageable by a single person. The sheets are joined together with a person on the inside tightening the nuts, as the person on the outside holds the bolts in place. No scaffolding or other heavy assembly supplies is necessary. A ladder, a few simple hand tools and you are good to go.’
