It can’t be denied that a tower has always a will of singularity and that its sculptural value is its most precious asset.
In this case, we don’t want to disconnect this sculptural value from its structural expression; we believe that any balancing act which its way of working is easily understood, responding to a carefully measured calculation, will reflect a tension that is, at the same time, harmony.
The history behind the emergence of this modest structure is highly unusual. We received a commission for a tower from the Prague 14 district government in an extensive future park. For it, we prepared three designs: one was a completely unusual construction from young logs, with which we had no previous experience, yet on the land in Horní Maxov, where our second atelier is located, there were several kilometres of them, and so we were naturally attracted to the idea of trying something with them out of pure interest in the penetration of nature into construction systems. To our great joy, but also our great surprise, precisely this tower was selected by Prague 14 for realisation. We said that first of all we needed to test this kind of structure, and so we created this artefakt. The word “artefakt” was used by us to keep it apart from the idea of a building. It is not a building, just a pure attempt, in which it was all about trying what this construction could do. Some might say that it looks a bit like a woman’s behind. A distant similarity could be seen. Yet the actual sense of the matter was to try out in all senses what a structure from young ash and maple logs could look like, how it could be put together, what structural qualities it has. It’s a preparation for the construction of the tower.
Project of the structural thin-bole construction tower in Prague, Kyje. Even though the tower isn´ t still built, the series of construction experiments has been made. The most important of them is the Artefakt in Prague, Kyje.
The history of the tower Bára has got all atributes of a dramatic story. Town council of Chrudim decided to build an out-look tower in the forest boundary, where the landscape provides beautiful panoramic view of the surroundings. An architectonic contest was made and as the winning project was marked the one by Martin Martin Rajniš from e-Mrak team. An out-look tower in the shape of truncated triangular pyramid, made out of larch planks with minimum number of fixed joints, secured by metal tow bars. Acces to the view platform is provided by circular oak stair, which is fixed on the convulated steel pole rod in the middle of the tower. Upon the view platform is placed a mast made of steel tubes with flashlight on the top. Out-look Bára was festively opened for public on the 21st of June 2008. Unfortunately, a massive storms, with a power of tornado in some locations, swept across the Czech republic just four days later. One of them appeared at the region of Chrudim and caused irrecoverable damage to the new-built out-look. Whirlwind left nothing but a mass of wreckage a few meters from the place were original out-look bas placed. However, citizens of Chrudim did not give up and the decision to build a new one was made almost immediately. On the 3rd of September 2009 was the new tower – Bára II opened. This new out-look is pretty much the same as the previous one was. It is just slightly lower and built in a way to resist the wind with power of a cyclone (approximately 200 kms per hour, in contrast to the previous one, which was able to resist only 130 kms per hour). Bára II has also got more security components, including steel cables with tension varying each thirty minutes according to air moisture. View from the platform is usualy the most interesting feature of the out-look, but Bara II has much more to offer. For visitors with interest in technics has to be pleasure to see the unique construction with number of simple, but clever details. Those, who are more into philosophy could use the wall of the tower as a source of meditation. Variation of horizontal wooden lines and gaps between them makes really delightful view. The structure reminds of water clarification and makes interferential optical effect, which is well known for its sedative action.
The urban district development “Gateway Gardens” is part of the Frankfurt Airport City. This project offers opportunities for major groups to position their corporate headquarters in a conspicuous location within an attractive environment at one of Europe’s main transportation hubs.
On a raised piece of land, find a place where rock protrudes from the ground. Place a truss made of four wooden planks onto stacks made of beams which are anchored onto the rock using threaded rods. Place planks onto the truss to form a square measuring 3 x 3 metres. Each unit is made up of two layers of planks interspersed with laths, with a thicker sticker consisting of double-width laths inserted between the units. Wooden steps forming a double helix are placed in each gap between units. There are sixteen steps per each full turn, i.e. 360 degrees. The helix is inscribed in a square. Use four-metre-long planks and laths straight from the sawmill, without planing or drying the wood. All the components are simply placed onto one another without the use of nails. Use steel cords on the walls to brace the tower. Place boulders with holes bored through them into four pits in the ground about seven meters away from the tower. Pull the threaded rods through the holes. The bracing cords are pulled through loops at the end of the rods. Weigh down the boulders with a heap of stones. It is all so easy that I built the tower with the help of a group of young people – students. Even so, there are a few important things one needs to know. So, please – don’t build without us!
The new building for the power station control centre of Tiroler Wasserkraft AG in Silz is a massive, tower-like, free-standing building. The dominant building on the site was and still remains the old turbine building. Various additions reduced the impact made by this building, with the result that the high-energy processes on the power station site were no longer externally legible. Through the forma idiom it employs the new building attempts to depict these processes.

The stairs arranged for seeing site of expo is placed like mountain path.These stairs definitely aren’t trying to hide – they’re the most interesting element in the tower. Reminiscent of a climbing mountain, the stairs of circulation are balanced by the long cable structure.Circulation elements can act as urban focal points outside of where people can come walk and seeing. The symbolic observation tower is conceived as a round arch of steel structure with an open-air stairs at its body.The open-air stairs contains flexible walking path and terrace which are accessed via bazaar entrance.Walking downwards from the top through a continuous stair promenade, the visitors of the observation tower experience all of the building’s in a constant motion, while enjoying dynamic 360 degree views of the city of Antalya and the Expo landscape.
