The Mast with a View is a small-scale intervention in the landscape, located in Libčice nad Vltavou, Czech Republic. It forms an initiation point, an intervention to stimulate engagement and enhance the importance of the site; the first building project in an area meant to be transformed from a neglected locality into a residential park.
The inspiration was the fame of Libčice’s historic brickmakers, who not only produced bricks but also specialized in the construction of factory chimneys, with over 1000 raised in the Czech lands alone. The mast bears aloft the town’s flag, and in its shape recalls the famed Libčice chimneys.
Standing at an elevated position in the heart of the future park, it forms the vicinity’s chief landmark and meeting place. It can be seen from the immediate vicinity, and at the same time offers an exceptional view of the Větrušice Gorge on the opposite bank of the Vltava River.
Structurally, the mast combines an internal steel structure and an outer wooden envelope, with both components working together to provide structural integrity. In total, the height of the tower is 7.9 m, diameter 1.85 m. It is grounded on a concrete foundation slab, which because of the difficult foundation conditions is reinforced at the corner with concrete pillars.
The steel structure consists of the central tube, the flagpole support, the stair risers, the base and the anchoring foundation ring. To ensure the necessary coordination with the external timber structure, the individual stair risers are welded to a steel tube ring that has the height of a single riser and positioned onto the inner load-bearing tube. Such a design allows for correcting the structure during the assembly process. The steps are provided with a diagonal brace strut on the underside to ensure that the entire structure interacts when under horizontal load from wind. Above the platform level, the Mast ends with its flagpole section, with the railing anchored to it. The structure is anchored to the concrete foundation by means of threaded rods. All steel elements are hot-dip galvanized.
The timber envelope consists of 16 vertical larch beams and 168 horizontal rungs. In its form, the wooden structure is inspired by traditional formats of brick bonds. The horizontal beams define the placement of the stair risers and are placed at alternating height between the vertical timber studs. Towards the center of the tower, the horizontal rungs are beveled to allow water to drain off the surface. Wooden elements, both vertical and horizontal, are connected by screws. The vertical beams are mounted on steel plates welded to the base ring and secured with bolts. The top ring reinforces the entire structure and serves as a handrail. It is three mutually shifted layers of wood planks, which ensures the concurrence of interaction of the ring in transmitting the loads and additionally the stability of the vertical post above the entrance, which is suspended from the ring.
The “Mast with a View” is a student design-build project by the Hlaváček - Čeněk studio of the Faculty of Architecture of the Czech Technical University in Prague. Design-build projects have a tradition at the world's leading architectural schools, but in the Czech environment they are relatively rare. As an alternative to standard teaching, this method enables students not only to invent and draw a building, but also to realize it with their own hands.
A 9-member team worked on the project over four months. In the first phase, everyone focused on their own individual design, after which the team together chose one concept which they finalized into production documentation and then built by themselves.
